Public clouds become revolutionary innovation in IT which is not just for small and medium-sized businesses. At the moment, most companies are experimenting with public clouds as a resource for development and testing or for production applications with low requirements for security, protection of personal data and service levels. It is believed that large companies of public clouds may be of interest only in a specific niche, given their large investments in legacy systems and the critical role of such systems for their business. Nevertheless, a number of these companies see great potential in public clouds. They feel an urgent need to make a choice between pro-active work with the public and the clouds behind the competition.

We talked with many of the companies to begin with development of public cloud services providers. Naturally, the applications that these companies would like to move to public clouds being studied to determine their cost-effectiveness in this model. We propose a generalization read reviews over the ten kinds of hidden costs in the public cloud. We have split these costs into four broad categories:

• one-time cost of migration
• limitations of the model of billing
• residual costs of management
• risk premium

Single migration costs

Its costs are associated with moving existing applications to the traditional, physical infrastructure in the public cloud, including costs to modify the application and transfer of server systems, and associated with writing off the cost of equipment depreciation.

In this category there are two types of potential costs, for which you need to watch.

Rewriting applications. In a typical company, the most used applications are not yet ready for transfer to the cloud. Certain applications that already run on virtual machines or developed in accordance with the standards of the cloud platform, are well-tolerated. But most require significant processing or rewriting code to ensure compatibility. This is especially true for legacy applications. Organizations need to assess the economic feasibility of the transfer of such applications. It may be cheaper to keep them in original form or to completely abandon them in favor of new ones.

Promoting standards of cloud platform and justification of the need to update technology invariably are difficult for application developers. This should be taken into account when considering the use of public clouds.

Write-offs for depreciation. Companies that choose to update the application or infrastructure to accelerate the transition to the use of public cloud, could face the impossibility of further depreciation of existing equipment for depreciation. This explains why many companies intend to begin the study of clouds, when the time comes to change equipment.

Limitations of the billing model

The current model of billing in relation to a public cloud computing has three features that may not correspond to the nature of your enterprise applications.

Award for flexibility. One of the most lauded features of public cloud is the payment of actual consumption, which allows companies to handle peak loads. Because prices are set properly, it could mean an additional fee for applications that are constantly in the public cloud and are subject to bouts of activity. What is important is the right choice with regard to each application. Applications that use smooth or predictable demand, would be economically efficient in the use of models for providing computing power on demand.

The fee for crossing the cloud. The fee for incoming and outgoing data – an important factor that we must always remember, especially in case of heavily used applications. Anxiety also causes an additional delay that occurs in the cloud of server hosting when requests for the transfer of large amounts of data.

Storage costs. Virtual multiplayer server architecture complexity and costly storage, causing the need for optimization through storage virtualization, storage, fast devices only frequently used data and deduplication. Most companies are just beginning to familiarize themselves with the appropriate tools.
Residual management costs

It is important to remember that you will not be able to abandon old service, which will have to continue to provide within the company, even after the transfer of applications in a public cloud.

Attention is drawn to four areas of management

Security, in particular update the OS and antivirus management. Of course, there are the usual and enhanced security measures to be taken when working with the public cloud. There are basic costs associated with software licenses, upgrades and maintenance when installing patches and antivirus software. These costs are present regardless of whether the company chooses a public or private cloud or traditional uses its own physical infrastructure.

Back up

Most public clouds do not provide backup. This is one of the many reasons why businesses often do not even consider the possibility of using public clouds. A significant part of the companies need to continue to maintain all the internal infrastructure for backup and data recovery. This is another cost item that increases the cost of public services, the clouds over the face value.

The redistribution of the load and automatic scaling. These capabilities are required to handle requests to the system, the optimal use of resources and prevent overloads. They require specialized equipment and costly new software. These costs are often passed on to corporate customers, but not to the providers of cloud services.

Services for integration. They are necessary to ensure full compatibility with the client installed and deployed in the cloud systems. Organizations that tolerate application in public clouds must be purchased for this expensive software.

Reward for risk

Use of the public cloud enterprises primarily should always be prepared for worst-case scenario. You need to prepare for the costs of transfer services at its own site in case your provider of public cloud collapses, or you just do not want more use of its services. It is important to determine the extent of the costs of such migration.

Here we should pay attention to the plan out the clouds. Requires thought-out plan migration from public clouds back to their own equipment (which is highly unlikely) or in another cloud (more realistically). Drawing up such a plan requires additional time and effort, as well as extraordinary financing. The companies that have already endured the application of a private cloud in the public or had a case to learn the standards of tolerance, migration costs will be small. But most companies do not have such experience. Therefore, for the transition to a public cloud, they should provide funds for the organization of deliberate withdrawal.

Cloud services typically implement common features and require an agreement about the quality of service (SLA). In such cases, the business model of the organization will face difficulties related to the management of cloud services. The cloud services management as a process of developing a system is aimed at using the power and possibilities of cloud computing to solve business problems. It is possible to use the experience of its own specialists, but there are other ways to effectively implement this approach in the organization.

With the spread of cloud services to enterprises, it raises a difficult problem to control their use and performance, as well as integration with internal resources. The result is a new area of activity – agent cloud services. By definition, an activity for cloud services management and their integration. These brokers may be the current VAR-value added resellers and system integrators. They will be responsible for compliance with SLA-agreements, and are most likely to specialize in certain industries. They are especially useful for small and medium-sized businesses that are poorly versed in the intricacies of the cloud services market and have difficulties when using them. Such brokers can take advantage of fast-growing cloud market and earn good money on services that they resell or integrate.

Office of the clouds will be the main activity of the cloud brokers. Indeed, cloud services providers are offering ready to use services, but generally do not consider the specific needs of your business and that these services need to be integrated into a single solution with other services that you supply. That enterprises can leverage cloud services, someone has to expand, integrate and customize. In most cases this is not required to make changes in the functional service, but simply to supplement or to aggregate them, while ensuring quality of service.

The basic idea of cloud computing is to allow companies to receive services in terms of outsourcing. If you want to create a completely new technology base and to train employees in the integration or expansion of these services (or their management), it will require large expenditures. Nevertheless, some companies are going to manage cloud services. Such an approach would be more exception than the rule, but if your company has chosen this path, you should make sure that it will solve business problems rather than complicate them. In addition, you must check the availability of a good reason to deploy the cloud infrastructure at the plant. Potential benefits must outweigh the costs and risks.

But most companies do not implement their own cloud, and appeal to a cloud broker. As there is a lot of demand for such services, it would increase costs for companies and the amount of related work.

Eventually this could lead to the fact that the company will be tied to a particular provider and a set of services, because investing in the expansion of services or integrate them, you will not like to lose this investment, changing services or providers.

Solution is to appeal to cloud brokers, who provide mediation service or aggregation of cloud services that enable your company to get what it wanted. With relevant qualification, they play a role similar to system integrators as well as provide managing cloud services to many customers. Over time, these system integrators will be VAR-Reseller of the services that are expanding. In this case, your company will not be tied to a single cloud provider, because you will not pay providers and brokers. If you want to change, you can change the broker, to appeal directly to the provider or ask your broker to provide other enhancements.

In the future, we would hardly expect a clear division between public and private clouds. Companies are likely to use different options, including hybrid models, virtual private clouds and the set of all possible combinations. As the distribution of cloud service providers should expect the possibility of setting the most popular services.

The emergence of cloud represents a major break in a traditional information technology services, which are no longer tied to dedicated hosting. The services began to move freely about the infrastructure, whenever and wherever needed. But it does not mean that companies need to completely reinvent their IT to implement projects in the cloud.

Many organizations have as their main objective of business agility in responding to demands to reduce costs to deliver services and minimize risks. The cloud hosting projects do not change those goals and, indeed, accelerate the process of achieving them. But to succeed in this movement, we need to undergo four major changes: infrastructure, organizational processes, services and culture.

1 – Infrastructure Transformation

Perhaps the most significant change involves the IT infrastructure. In this scenario, it is no longer possible to maintain traditional architectures fragmented, with stacks of applications and data segregated into silos of hardware. The architecture of cloud computing services is unified and smooth. Applications and data move through the cloud to deliver services anywhere and at any time.

And how to transition from a fixed to a fluid environment? You can create environments for testing. Thus, it creates a period to gain experience and further scope of the project, including critical systems.

2 – Transformation process and organization

Over the years, organizations have developed best practice processes for IT disciplines, such as those based on ITIL (IT Infrastructure Library). These practices provide large gains to generate agility, reduce costs and avoid risks.

These processes must be maintained when a project starts with cloud services. And there are several ways to use them, even if it is necessary for some sort of change adaptation processes and increased harmony with cloud environments. For this, there are several technologies that simplify and automate that process management in the cloud.

A service orientation requires an organizational structure for IT that is capable of managing and supporting a cloud environment. The transformation may involve several new functions. For example, the company can replace teams structured by lines of technology by teams such as service administration or management of IT products that work in a service perspective that crosses all technologies.

3 – Processing Service

The ITIL best practices are focused on helping organizations to move in a service perspective. Cloud can support this approach by allowing executives to request services themselves, which increases the agility to meet business needs.

Business executives do not care about the components of IT infrastructure that need to deliver a service. They want speed in a service request and delivery on time. To meet these requirements, standards facilitate the request for services, and simplify management and reduce costs.

The management of business services (Business Service Management) helps companies transition to a service-oriented approach to service management. BSM is a comprehensive and unified platform to make IT work. This lets you manage the infrastructure of a service point of view of linking them with hidden components of the IT architecture supporting these services. Thus, the technology department can manage services based on the impact they have on business, increasing efficiency.

4 – Cultural Transformation

In the past, some departments had budget or organizational difficulties and, consequently, were slow to meet the demands of business. Today, cloud services brings agility, meeting minutes in service demands, which represents a major cultural change not only for the IT area, but for all departments of companies. Thus, executives may be more agile in responding to market changes and seize new opportunities.

IT must be the driving force behind the cultural transformation. Effective communication of the benefits that cloud computing can bring is essential. The message to be passed is that people can request services without effort, fulfilling orders without delay and user expectations with quality services.

Putting It All Together

Cloud hosting is transforming all aspects of IT: infrastructure, processes, service orientation, organizational structure and corporate culture. But despite all the changes this is still an ongoing process, and companies can move to the cloud without putting aside all that has been developed in its traditional environment.

The corporate objectives are still the same: get to be extremely agile in responding to business demands, reduce costs to deliver services and minimize risks. Cloud Providers can help to achieve these goals, and companies can use technologies (virtualization, automation and portals) that provide a basis for design of the cloud. ESDS Data Center helps you to manage services, achieve maximum value, strengthening the ties between IT and business, help to ensure the success of businesses.

In meteorology there is a detailed classification of clouds, numbering at least 12 species. IT professionals do not lag behind in this regard- they can conventionally distinguish several categories of “cloud services“.  It should be noted that the conventional classification generates a certain amount of confusion in concepts, so it’s important to give at least a brief description of categories.

There are three major types of cloud-based technologies: SaaS; software as a service, PaaS; Platform as a Service and IaaS: infrastructure as a service.

SaaS Model – A lease of the software, which is developed by the service provider, and the user can access it via the Internet. This model allows us to reduce the cost of implementation and maintenance of software. A striking example – popular with the U.S. system of Customer Relationship Management Salesforce.com. Paying for its services in proportion to consumption, you can use the ready business process for working with clients. This completely eliminates the need for costly implementation of the system in operation.

PaaS Model involves the provision of a platform as a service, for example, to develop or test software. Thus, any organization can get the missing computational resources for the development and subsequent operation of their own applications. Google App Engine is one of the leaders in such services.

Finally, in case IaaS as services are provided by the hardware resources (infrastructure). IaaS feature is that, this model consists of three main elements – a hardware component (servers, networking equipment and other), the operating system and middle-ware software to manage the first two components. Such services are in a cloud of ESDS “Data Center“.

From my experience I can say that, from the three models of the cloud on the market, today, IaaS is in demand. Gradually, the demand will grow for other models, but so far IaaS is closer to potential customers. One reason for this phenomenon lies in the fact that “cloud” infrastructure involve the use of virtualization technology, which allows you to create boundaries between different users of the cloud.

This is especially important when it comes to the use of cloud computing for large customers.

In addition to the above types, it is important to distinguish between the “cloud” type property – public clouds and private clouds. So, if the company rents a “cloud” from a third party provider, it works and stores its data in the public cloud. This option is suitable for companies in the sector of small and medium businesses (SMBs), as well as for projects in the initial stages of development (start-up). If the company creates its own data processing center (DPC) or within an existing data center expands ‘cloud’ for the needs of its employees, affiliates, etc., then it is private cloud. The second option is suitable for large companies who are interested in reducing costs to ensure the manageability of the infrastructure and software. Thus, in this case the “cloud” is an excellent way to centralize all the IT systems of large holding. Using a private cloud, the company receives all the benefits of the cloud and thus has the ability to completely control its software and content.

It is important to note that, it is economically feasible to create a “cloud” that is only based on its own infrastructure. They can also extract some benefits from the use of public cloud, for example, in test mode to get acquainted with the proposed business applications in order to make the final decision on the necessity of their implementation in their own information environment.

When the market began to talk about cloud computing, the most attention in the industry was focused on the concept of public cloud. A situation triggered by the release of the model by large providers such as Google and Amazon. Today, however, the priority of IT departments who study the adoption of cloud architecture is to invest in private cloud , primarily because of issues related to security.

According to a survey of IT executives, issues of security and privacy are the main barriers to adoption of cloud computing. Still according to another study conducted , 75% of the professionals who plan to adopt cloud computing by 2012, give priority to private cloud.

However, the private cloud providers also have their share of challenges and they are not just restricted to security issues. The difficulty to identify and manage operational processes is still a barrier for many projects in addition to the investments and the preparation necessary to migrate the traditional IT environments for cloud computing.

In fact, replacing a conventional data center – even one with virtualized servers – for a private cloud architecture is not an easy task. To make matters worse, there is no market suppliers of solutions for this type of environment and the industry differ on the basic concepts of cloud computing.

Virtualization Is Only One Of The Point

In the view of many IT managers, the cloud amounts to a virtualization solution. Usually, what they describe as a cloud design is nothing more than a virtual structure, i.e., the equipment and systems sharing resources on demand.

“Virtualization and cloud, however, are not the same thing”. Cloud to be seen, the architecture needs to have the layer of management and virtualized automation. This means offering a variety of resources – processing, storage and networking – as a service.

In the cloud, a single command or request triggers a series of actions “and the sequence in which they occur is easy to specify and coordinate with.”

Comparison With Usual Data Center

In a data processing center of the conventional type, each time a new server is implemented, a professional must do all necessary settings and integrate the equipment into an existing infrastructure. In the case of private clouds, such human intervention is minimal.

In this environment, you can make settings for a single console. Thus, the IT staff is free of the task of ‘place’ in different terminals to adjust security settings, network and system functions with.

Another difference between private and cloud data centers involves usual IT processes. To take advantage of the cloud, often, companies need to readjust the data architecture and review some cases. A classic example is the rules to seek investment to acquire more storage capacity, network or servers. Overall, IT departments must meet a series of requirements. With cloud, the purchase decision may not take weeks, but may get limited to just minutes.

The services in the cloud computing are growing with increasing speed over the following days, with this, the initial cost of launching products fall as a result of which businesses can develop, build more for less money and with fewer people. This change, although in the long term, it means that there will be fewer positions in IT, what distinguishes today’s labor market technology, will be the desired skill sets.

Apart from usual software products, web services and cloud services are around the capital that generate content and data. Part of the installation configuration and maintenance works which are carried by people, are becoming automated, resulting in having a skill set focused on the supervisory talents, experience and knowledge of users did not return to technical work.

With the IT market in expansion and changes occurring in addition to training degree in computer science or engineering, some emerging skills should be taken into account for the professionals of the area that must remain to allow competition in the labor market.

The one who combines statistics and artificial intelligence methods that detect patterns in large amounts of data, has good job opportunities waiting. Data mining helps  to gain advantage over competitors in the information, which today is an important field in the environment we live in- the one takes over who knows more knowledge gets  better opportunities.

The research and site traffic on the web generates its revenue. Companies need people who know and are able to analyze the interactions of users and trends, to make a SWOT analysis, which allows finding strengths and weaknesses and opportunities amidst the changing needs of the public that is increasingly demanding.

With more information to filter inside companies, they need people to translate this data and transforms to talk business, we are talking about business intelligence. The greater the flow of information, the greater the need to have professionals who understand the subject, which have competitive air and know how to pass a team what the customer wants.

The skills listed above are additions to the university education, because the colleges are still trying to shape the curriculum for IT students, giving them knowledge deep enough to face the job market with a difference.

The field of information technology is large and the students are not easily graduating with a specific set of skills that enables them to work in a company. Cause they have information at different levels, will allow them to leave with a sufficient set of knowledge and unveil what is thrown in their path.

Search for learning on your own initiative, opportunities for university research projects or internships,  even without affinity for all activities that are established, work on an already established product, it helps a lot.

Speaking about languages for web applications, the practical options are JavaScript and Flash technologies because they are dominant, so study them and get acquainted with them.

For every personality, experience and education are different, and each company will get what you want.
It is important to be dominant in area of knowledge and general understanding of everything, this will depend on where you want to work.

Large companies have significantly greater resources than most startups, technology companies to hire more specific positions. It is important to have knowledge and understanding how the system works overall. With these contradictions, trends and software, hiring people who adapt easily to new technologies, ends up being a better investment for most companies.

Being proactive and passionate about what we do, take advantage of the skills that will acquire and work. Get knowledge, understanding a specific area enables the IT professional to have a competitive advantage in the labor market, as he has the new qualities and abilities needed for the area of web development.

So, first it was the mail systems, then the CRM, however, in the Enterprise resource planning world, the change never comes neither quick nor easy, but when it does, it stays. And in the case of cloud models, it is not an exception.

Soon many companies will have to choose to upgrade their ERP software and then have to decide whether to continue with the costly traditional models or move to cloud-based systems or not.

With traditional software systems, the return on investment can take 4 to 6 years. In any of the options offered to us by Cloud Computing, either through public or private clouds, taking advantage of these new technologies leads to a rapid return on investment, making the decision to the CIO and IT management. This fact may push companies to make the final leap into the cloud.

The Cloud Services not only brings economic benefits to the company, ERP allows to have real collaborative environments where we can create spaces for group work, improving organizational efficiency and business relationships. And all this in a simple, fast and scalable way without causing headaches for the IT department.

With regard to SMEs and micro companies, they undoubtedly benefit from large ERP systems online, as to the advantages discussed above we must note that it will allow the users  to use applications and infrastructure as technologically advanced as those used by large companies, and all by paying a small fee. In addition, online ERP due to its scalability, can help SMEs on other fronts, such as international expansion or the desired reconciliation of work and family life, facilitating the mobility of employees.

So, ERP in the cloud is advantageous for the company and may become one for the supplier: cost savings in maintenance and distribution allow to obtain more reliable and competitive products. As for the design of online applications often used such as ERP web browser interface, here the provider will have to make extra effort in R & D for its solution compatible with different existing platforms and give at least Speed and ergonomics applications in-house.

In short, online ERP are becoming more attractive and more companies seek low cost solutions, rapid deployment and ease of use. This is where the dual-ERP SaaS has a promising future.

In the past, IT managers and IT staff had similar priorities and objectives. They needed to streamline internal operations of companies with systems enterprise resource planning at the enterprise level. They needed to increase employee productivity by introducing wireless access to the commercial units within the office, as well as develop and implement new technologies for more effective work.

But the situation has changed now. IT managers are increasingly looking to IT departments as a means of introducing new solutions for business. At the same time, they realize that the existing IT-organization established in accordance with previous commercial requirements and to meet the new requirements they often have to transform. This explains the interest of IT managers to “cloud hosting” technologies that can be used in IT infrastructure.

With regard to IT departments, they are trying to keep pace with technological changes in the IT industry, as well as maintain all existing systems. Cloud computing is usually not included in their list of priorities. They care about security, enterprise data management and ongoing system health.

This new distinction priorities CIOs and IT managers raises the issue of choosing the format of cloud computing, which most suit the specific enterprise. In favor of choosing one or another variant of such arguments are usually:

Public “cloud” requires less spending, but we need to pay special attention to safety and accessibility of data. May need to reprogram the application.

Public “cloud” offers the best IT infrastructure, in particular a more efficient use of resources, but to take advantage of this new technology, you will need to learn new skills to crossover, and increase the level of automation.

Outsourcing of cloud services (from data center service provider) can also be considered as an option, as the market appears to get more and more relevant offers from trusted providers.

Choose a way to transition to the cloud by using the architectural concept of Data Center Business Advantage. This concept allows customers to determine the extent of participation in the IT transformation and the need to engage in this process is a trusted IT partner by using their own resources or hosting services. As a result, the company receives “cloud hosting” services in the version in which you want, and its professionals can use their existing IT skills.

For customers who want to create a more powerful, more flexible and efficient computing environment, ESDS offers a unified computer system. IT serves as the basis for a private “cloud” and can be easily combined with such complex decisions as Vblock and SMT, which include virtualization, computing, network and storage systems .

In addition to the IT infrastructure, ESDS offers the cloud-based services that can interact with enterprise architectures.

Ultimately, the “cloud” – is not a product, but rather a range of services that improve the functioning of the IT systems of enterprises. As a Data Center Business Advantage, it is tied for first place on commercial needs. It creates a flexible infrastructure to provide the necessary new applications, and allows you to manage risks associated with the services provided to users.

Below I detail what I understand about the advantages and disadvantages of SaaS and PaaS, and of course what influences decision making in business. To a greater or lesser extent all these relate to paas saas and therefore I have chosen not to separate them.

Advantages:

Less initial investment and less risk, the use of the software without having to make an initial investment in machinery, software base (so) and additional software to run the application they would need in an environment in-house, is an important benefit for IT managers and ultimately for the company.

Cost reduction, in addition to paying for only what you need, you get a cost savings of maintaining the platform of machinery and the necessary software (databases, application server) to run your application.

Immediate updates and new features , a party that will not require dedicated staff for updates and software upgrades immediately. Sometimes we choose to use new features.

Support more agile and quick implementation. Bugs have a direct treatment and commissioning solution faster than in-house facilities.

The company focuses its efforts on your business , you really are outsourced to the point that systems do not expend effort in the choice and maintenance of systems.

However, always require care dept. IT but to a much lesser extent.

Increased availability and data security, against what may appear and in view of the disadvantages that we will see below, many companies have no procedures for backup, restore and general contingency plans in case of loss of information or hardware failure.

Most companies that offer software as a service offers an SLA (service level agreement) as to each type of user.

Disadvantages :

Low confidence in data security, the fact that corporate data can be critical or not but it is private, not located within the walls of the company is something that is not generally liked and especially to senior management in some occasions it is conservative and skeptical.

It remains an arduous task to convince and exposure of the idea by the IT manager the rest of the policy. Typically, it begins to introduce the idea of software as a service to applications that manage critical data (human resources, billing, law, etc.) and quantify the benefits of SAAS through a control panel.

Integration with the rest of the systems applications, as normal will be installing applications with local or in-house and SaaS, there is increased complexity in case you want to connect or use the data we have in the cloud with the data we have in the company.

This increases the degree of importance as to keep data in the cloud is important.

Need for availability of cloud data, if in addition to the above disadvantage the application or platform does not have a system (web service, API, etc. ..) that allows to extract data, is a clear disadvantage for not adopting the application in the cloud services.

Feeling customer captivity, but in general we have the same problem in-house facilities in paas-saas or where the volume of stored information is important and if we add the latency and speed of internet, can be decisive for the choice of software.

Possible breach of the agreements on the level of service, is related to the degree of confidence we have about the software vendor or platform as a service. We put in the hands of a vendor performance and application service we are aware of its advantages, but its disadvantage is whether comply with the agreed service level, and obviously is something that should have it in-house would take into account or not .

Why do companies like Amazon.com, Sun, IBM, ESDS, and many others are developing Cloud Computing infrastructure?

To try and understand it, going back 100 years ago and see how was the evolution of electricity.

Soon after the invention of electricity in the late 19th century people (and companies) have built their own sources of energy. People realized that it was easier and cheaper to buy energy than having the responsibility to keep their generators and taking care of all infrastructure required to have an own generation of electricity.

Perhaps the time is coming when the people think to keep their own data centers (unless this is the business of your company).

Each company with data centers?

Because every company or business (regardless of size) must have its own server farm to host their applications, their ERP, CRM, their databases.

Some of the small and medium enterprises of our servers are used in part: only about 20%, consuming 100% of energy. This is a problem. The bad news is its going to get worse. We will not have an inexhaustible source of energy that will enable rapid growth of the number of servers and PCs in the world.

Green IT initiatives and other help, but the concept of Cloud Computing, in my opinion is what can actually optimize the utilization of software, hardware and infrastructure, more effectively. Each company or individual will use only the resources it needs, at the time that is needed.

I have a friend who has in his house (he, his wife and daughter, 10 years): 03 laptops, 02 PCs working as robust home server, so many monitors, external hard drive, 02 broadband connections to meet the demands of their jobs … … and I think rightly, to consolidate some of the machines on a server. If this is a reality in many homes of middle and upper class, imagine how much the hardware base is increasing in business.

Is Cloud Computing ready to be used in companies?

Let’s see what this study says.

Cloud computing is a new IT outsourcing model That Does not yet meet the Criteria of enterprise IT and isn’t supported by most of the key corporate vendors. It’s wildly popular with startups, Exactly fits the way small businesses like to buy things.

Applications that can benefit from Cloud Computing:

• Those who need to access information in real time
• Security systems and transportation
• Payment systems and financial services
• Virtual worlds (Second Life) and social networks
• All applications which make billions of mobile devices (doing) use

The infrastructure needs to improve (a lot!), Especially here in India.

How companies can ensure availability of services?

Look what happened to one of the most popular services and one of the best examples of Cloud Computing:

And if your business depended solely on cloud hosting services, the future of processing enterprise seems even to Cloud Computing.
