With the advent of dedicated streaming servers, listening to online music and watching videos are so much a fun, now we need not spend much of the time at buffering for listening to music or watching online videos.
A dedicated streaming server is much more than just the hard drive, a dedicated streaming server integrates the software that is required to deliver media through our internet connection. Many protocols are required to help the audio or video travel from one device to another.
In streaming servers the users visit a web page hosted on the web server and finds the files they like to hear or watch, the web servers send the request to a streaming server and then it sends the file to the user with a little help of a web server.
Dedicated streaming servers are able to deliver audio and video in real time, which is due to the types of protocols they use. RTP (Real-time transfer protocol) RTSP (Real-time streaming protocol). Now these protocols are acting as layers that look after the web traffic. As real-time protocols direct media streams to where they need to go, other web protocols are simultaneously working in the background. Overall, these protocols work together to balance the bandwidth load on a server.
Dedicated streaming servers are designed to handle a large number of traffic in the website without any downtime. A dedicated streaming server provides an enormous amount of network storage to avoid streaming latency. A dedicated server answers the need of streaming video as it provides massive amounts of bandwidth, 100%uptime and maximum amount of storage.
Dedicated servers provide a good amount of bandwidth, so that the servers are ready to supply Streaming of any size project. Dedicated streaming servers are fast, they can also increase the load time for the end user, and are very capable of handling higher volumes of traffic and site usage.
Dedicated streaming servers offer high bandwidth connections to the internet, to serve millions of users, dedicated streaming servers provide huge bandwidth, and dedicated traffic so that there is no stream. Without dedicated hardware that routes traffic to maximize throughput, the streams would fail or buffer. A dedicated staff that provides 24x7x365 supervision supervises dedicated streaming servers. In dedicated streaming servers all systems are optimized to take irregular loads, and can handle high bandwidth demands on them, so the uptime is nearly 100%.
The SAP-ERP – (System Application Product – Enterprise Resource Planning) uses a three-tier client-server architecture, consisting of:
With this structure, it is possible to distribute the tasks to other machines with increasing demands, thereby increasing the efficiency of the overall system.
The various SAP ERP Hosting components set a custom relational SQL – database ahead, which is not supplied by the company itself. SAP ERP and the SAP Web Application Server support in addition to the in-house SAP MaxDB – common products such as DB2, Informix, Microsoft SQL Server and Oracle.
The entire business processing is done in the application server through special programs utilizing the proprietary programming language ABAP / 4 ( Advanced Business Application Programming Language are written) and through tools such as Data Dictionary, mask generator to supplement or Query Management.
The programs are executed within a specific runtime environment, which is called SAP “kernel”.
The kernel is in C programming and can – in contrast to most of ABAP programs – will be viewed but not modified by the customer. The kernel abstracted from both the conditions of the operating systems used and of the special SQL – syntax of the used DBMS, so that ABAP programs on all platforms are capable of running for ABAP kernel.
The kernel contains the following essential components:
The processes can be distributed as needed depending on different machines. The simplest case (all processes running on an application server) is referred to as so-called “central instance”. For smaller scenarios, this arrangement is sufficient, and often can be maintained and the database on the same machine. Some components (especially locking and update processes) may exist only once per system, the “workhorses”, however (the dialogue and background processes), which perform the actual program execution can be distributed across multiple machines. The combination of database and application server processes is called ERP system.
Unlike most of the smaller ERP systems, numerous variations of the functionality can be set only by parameters in SAP ERP. The adjustments to these settings are as customizing designated and must be performed for each implementation of the system or module.
The plurality of parameters is controlled by means of several thousands of database tables, which are evaluated at run time. Your care is via a tree parameter, which is constructed similar to the application structure for modules and Care Masks and function information for the permissible entries offers.
Alternatively, this can also be done directly on the care of the control tables.
Are the settings through the existing customizing functions no longer represent the standard programs in a number of places extension points available, where via a defined interface customized program parts can be embedded in the standard processing ( User Exits, Customer Exits, Business Add-Ins (BAdI), enhancements).
If these options are not enough, (almost) all standard programs can be modified as per customer specifications. These “modifications” are recorded automatically in order to assign responsibility in case of errors can. Because of the increased sequence expense (balance during the update of the standard programs) modifications are, however, avoided if possible.
The interplay of the various parameters is only partially documented – adaptation to a company therefore needed on the part of the responsible consultant a certain experience.
Adopting cloud computing is no longer a matter of whether or not to adopt, but rather when and with what intensity and speed it should be adopted. This pace will depend, among other factors, the degree of maturity of the company and its IT department, its positioning strategy in the market, the degree of adherence to innovations and, of course, also external aspects such as availability and capacity communications infrastructure that meets the company requirements. The IT department must lead this process and, therefore, analyze the risks involved at your own risk. The success or failure of adoption of cloud depends on how well it is designed and executed.
A few years ago, cloud was curiosity and it is natural that the cloud providers themselves are still in various stages of evolution and maturity. As the word cloud has become a hype, any service provider began to show the market as a provider or expert in cloud offerings. Thus, hosting and colocation providers, from one day to another, become cloud providers, changing only the advertising of their offerings. The cloud offered by them is still hosting or colocation. Companies on-premise software become SaaS providers simply creating instances of your application on an external data center. It is the old ASP (remember?) Masquerading as SaaS. So while cloud is an inevitable trend, the path to it can be a bit rocky …
How IT should act? To Draw a cloud strategy, is a key. This involves defining which applications will go to the cloud, following their migration, and whether these are private or public clouds, or even if both solutions coexist interoperating. The strategy should define where to start. For minor applications? Or for that are more independent and do not require interoperability with other? Or by seasonal applications? Finally, each organization should define its own strategy.
For example, an ERP is a lot of demand characteristic interconnection with various other applications. Take it to the cloud means that these interconnections have to work satisfactorily. And where are these applications? In the same cloud ERP or other clouds? Or continue on-premise? An important and often almost forgotten factor is that, most often, we look at the very low processing costs offered by cloud providers, but the costs of connection (communications) can be high if the volume of data exchanged to maintain interoperability between various applications in cloud and on-premise is very high.
This is a scenario that most medium and large companies will have to endure for long. It will be very difficult to migrate to cloud computing in the Big Bang model. It is a gradual process and therefore the coexistence of this complex and interoperable environment must be considered in the migration strategy.
Migrate to a public cloud does not mean giving of IT governance. This, however, becomes more important. The IT department no longer worry about issues such as installing new operating system release, but must keep track of the level of service performed by the cloud provider. The roles and responsibilities exist today in IT should be redesigned to be distributed and shared between IT and provider.
The choice of provider is another important variable.
Hardly a company born and raised by B2C optical can turn into a successful B2B.
The cloud strategy should involve other areas beyond IT. Risk Management, audit and legal are some examples. Issues such as sovereignty of the data, ensuring adherence to industry regulations which the company operates, the issues of audit trail, issues concerning migration of data and applications in case of exchange of the cloud provider, are among factors that IT will need much support. There are also legal issues regarding the use of current licenses for on-premise software in external clouds. The contract with the provider’s own demand variables, the on-premise model, need not be considered.
An example: If you terminate the contract with a cloud provider, your data will still be stored in it. What conditions and technologies it offers so you migrate to another provider? Or the provider changes, without notice, its data from a data center located in your country to another country, creating a regulatory inquiry. Anyway, are variables that the IT department does not have enough to act autonomously expertise.
The migration process is an important element. Will be treated as any flaws in the operation? Who will be responsible? What is the role of the provider and its IT in every aspect of migration? An important and should be carefully analyzed aspect is to capitalize on the potential of certain public clouds, you will be required to use specific technologies and APIs, which can create a lock-in and substantially delay or any change of provider. Some cloud providers keep under wraps its technology and access to their data centers. This can create complications in case of need for forensic investigations and audits.
Cloud computing is not magic. You, adopting a public cloud, is transferring its hardware to software. You will only see virtual servers. But these virtual servers need the data centers of the cloud provider. Your limit is the limit of the provider. Generally, this limit is infinitely greater than what most companies have in their data center, but even so, some care must be taken. Do not forget that a cloud provider, for profit, need to share the most of their physical resources among its customers. Eventually, you may encounter bottlenecks arising from this share, as interference from other customers who cohabit the same physical servers that make up your virtual or sharing of storage and networks that connect these server machines applications. And the ever-present bottleneck, here in India, the limitations of our broad bands.
Therefore, the IT department has a very important role in the design of cloud strategy. Should lead the process and not be driven by it. Otherwise, when problems arise (and always appear), will be forced to chase the game. Thus, it is fitting that the lead and creating policies and practices of adoption and use of cloud computing.
The fact that mobile devices such as smartphones and tablets are becoming cloud devices is not new. What is new is that we’re really getting to the saturation point of these devices, leading to greater use of the cloud for mobile applications and providers. Use one that should increase even faster this year.
Smartphones and tablets are getting faster, more capable, and their applications, more sophisticated. My smartphone can download data faster than most DSL services can, the user interfaces are easy to handle, and the applications are equal or superior to what we can find in a PC. In fact, if not for the fact that my smartphone to have a 4 inch screen, I would have written this post on it.
This does not mean that mobile devices have reached the maximum of their technical capability. Suppliers keep finding new ways to improve them. But this task is becoming increasingly difficult. Therefore, the push toward innovations that improve the use of smartphones and tablets are migrating to the cloud solutions.
Side infrastructure, the cloud is already playing an increasingly important role. With the use of SDN, some operators are moving the base stations to the data center. This is important because the base station is the most expensive part of a cellular network. Moving it to the data center (and the cloud) allows the operator to provide sufficient processing capacity in each cell, being better prepared to handle peak traffic, allocating processing resources in parts of the network where they are most needed at any given time.
Also the platform vendors like Apple and Google are pushing computing and storage to cloud-based platforms. Good example of this movement are Google Drive support for document editing and expanding iCloud editing capabilities from the iWork suite.
In fact, mobile devices are becoming more data friendly than stand-alone terminal platforms. This provides better performance, resilience, and of course, another source of revenue for suppliers (again, Google Drive and iCloud are good examples).
On the application side, application providers are taking the same path as the platform vendors, which means greater use of the cloud. Application providers are focusing on development tools for native cloud applications and trying to push as much processing and storage systems to back-end.
Of course, this means more reliance on network connectivity and bandwidth, but this problem is being solved with the increasing use of WiFi, 3G and 4G cellular networks.
The growth of mobile technology has clearly changed our lives. Now, the increasing use of cloud will drive more and more evolution of mobile platforms and infrastructure.
It is now fashionable to point the finger at data centers as part of their energy consumption. But it’s a bit soon to forget that they are solid tools for reducing the carbon footprint! Digital technology has changed our habits and reduced our environmental impact: a few clicks are enough now to book train tickets, without the need to move. But beyond this (r) evolution, data centers themselves also contribute significantly to reduce the carbon footprint.
1 kilowatt consumed in a data center is 10 kW would be consumed if it does not exist!
Imagine 300 companies each with their own infrastructure: 300 inverters, 300 air conditioners, generators … In comparison, a data center can accommodate 300 guests, is equipped with fifteen inverters shared! And this equation is repeated for each device. Infrastructure sharing gives the title to the data center a virtuous impact on the carbon footprint of companies.
This is not an end in itself. Many innovations can still contribute to reducing the energy impact of data centers. The news shows us regularly that many projects exist to optimize or reduce the energy consumption of data centers ( server cooling oil bath, use of the heat generated by the servers to heat installations communities or businesses proximity, test fuel cell , etc.). initiatives that will ultimately optimize the energy produced and consumed by them. But it takes to much stick to it? Being “responsible”, is it limited to reduce its own energy bill? Or is it to go beyond its own interests?
Research funding, use of ecological materials (cables without PVC , banning of chemical additives in air conditioning systems, etc..), design of the building to prevent any discharge of liquid effluent in urban networks, construction of the center under construction green label, subscribe to + Balance Certificates of EDF, the use of “electronic nose” analyzing chemical particles in the air to maximize the direct input of outside air as a means of air conditioning, etc.. are all measures that contribute to reducing the environmental impact of our business. While these initiatives have a significant cost, but be “responsible” is also investing in future generations. And experience shows that a company can now be perfectly profitable while leading a highly political “responsibility”. Therefore, it is essential that manufacturers who engage in this virtuous path are recognized for their efforts.
But again, we should have a tool to measure the energy performance. The PUE (Power Usage Effectiveness) is so far the benchmark for data centers – which in addition to the overall energy performance of the site that reflects the improvement or deterioration of performance of the latter as well as the savings generated by technical investments. However, today it shows its limits:
All factors that qualify the relevance of this single performance indicator. This does not mean that we should dismiss definitively, but it cannot be the only measure for energy performance of data centers. Latest indicator, CUE ( Carbon Usage Effectiveness ) has the advantage of measuring the carbon footprint of a data center (dividing emissions CO2 by power consumption equipment IT it hosts, on an annual basis).
Investing in innovation! More than ever, this must be the leitmotif of data center operators wishing to plan for a sustainable future.
In most cases, companies are looking at the connectivity, physical security, building characteristics, the financial stability of business, etc …
While all these features are important when evaluating data center service providers in india, companies must also focus on the factors that play an important role in ensuring high availability of the service, such as business processes, the organization of services, the maintenance policy and the equipment life cycle .
Control procedures and documentation processes are also critical spots. Able to know the downtime not nocplanned and the log of the last incidents is a very important point. In addition, many incidents are the result of human error.
Therefore documenting and validating process is a very important point. For most procedures are reliable and known more likely it is they will be followed, and the less likely that human error causes a service interruption . It is also important to know how these procedures are distributed and what are the associated training .
On SLA ( service level agreements ) it is essential to know but also how they are managed operatively. During diagnosis it is important to understand how SLAs are implemented and how they are monitored and measured.
Each company’s requirements, needs, and it is very important to know them. Then looking for a web host often resembles solving an equation with unknown x.
Solve, make the right decision is to ask the right questions, get into the details of the procedures and internal policy. Because these elements are essential safeguards to achieve true high availability.
If this topic interests you I recommend reading this Article ( How to Build a Data Center ? ). It allows you to understand the building infrastructure of data center when searching for your hosting provider.
Has the internet effected your life? Currently you no longer need a computer to write a text, you do so on your tablet, phone, or how about the Google Docs? Or even reach a customer? You can gain new customers through the internet, there are businesses and people earning your valuable money via Internet. A great example is the team’s “Back Door” is a comedy channel that started gaining public via YouTube, posting videos, its beginning was in 2012 and today has had videos that have reached over 1 million internet users.
How cloud computing solutions effects this?
Cloud computing is a form of the central computer (server) perform all processes that should be done on your home computer, as a result you get just the result of this processing. A tool as an example, is the google docs, you create files for it and just type text, the rest is a google server that processes the data and makes the whole job.
Ok, and how cloud computing effects me?
Effects a lot! With cloud computing growing every day, computers for jobs of the future will be cheaper, requiring only the ram-memory, processor and motherboard. The google has given some indications that it will release an OS for the internet, you will not even need a HD, because your data will be hosted in the cloud, requiring only an Internet connection. If you are opening a business, I recommend you to look for a good business or professional who understands the concept of cloud computing.
Software of the Future: Cloud
Today, you simply hire a professional or a company who understands SEO, cloud computing, and it will make your company earn more and save you any costs because you will not need a technician, another example is that with cloud computing, the software updates (system) for your business can be conducted without the presence of a technician.
As we have seen, cloud computing is the future and will only grow, we see everyday people increasingly using the internet to access information and even have meetings. Update your company with a system in the cloud and enjoy its benefits, software that are installed on your computers are already getting in the past and it tends to increase more and more.
But there is growing concern about what could happen in a world where so much information is stored in the “cloud computing”.
For many people, the worry begins with a term that is already very difficult to set and get their heads around. But it’s actually not that complicated. The “cloud computing“ simply refers to an off-site server where the files and data are stored for future use.
Nowadays, the amount of data being stored and accessed in this manner is increasing daily. In fact, you can think this way – if you need an internet connection to access something, it is probably using the technology of cloud computing.
In and of itself this is not a bad thing! It has provided the world with services like streaming video, webmail and a huge amount of cool apps on our phones!
But many are starting to worry about as a loss of such data that could complicate their lives.
And rightfully so. After all, the concept of this technology speaks about your main drop – a loss of control on data directly.
It is one side of a double-edged sword: Firstly, placing the data in the cloud can significantly increase accessibility and hence productivity. It reduces the need for constant updates and system hardware.
Moreover, since data on some server, it cannot be directly monitored… In other words, it’s out of your hands.
Needless to say, this can be somewhat troublesome in the event of a disaster! But fortunately, there is a large industry that is developing to deal with such situations. Draas – Disaster Recovery as a Service, is offered by companies as a way to minimize or reverse the loss of data in such a situation.
It is easy to see why the demand for this company is kicking into high gear! Many fear a systemic failure as never before. Cyber security is becoming increasingly critical with each passing year. Most areas of our lives are now fully connected to internet technologies. And it’s probably only a matter of time before “real life” is perfectly integrated with the web.
How can we walk deeper and deeper into the cloud (new territory for the human race!), There is a great need for a system checks and balances to offset declines incredibly beneficial potential of this technology.
And disaster recovery services will likely continue to play an important role in the development of this cloud computing system.
One thing that becomes very crucial in Disaster Recovery is a data and information, as mentioned earlier, it is very important to maintain the consistency of data and information for the company. These needs can be accommodated using data replication technology. Data replication is a process that copies the contents of the data to a remote location either that lasted continuously or at specified intervals. Replication of data will provide complete results of data copy for disaster recovery purposes. Remote Location is usually a secondary data center.
Data replication technology has complicated functions as intelligently copy data to a location that is remote, once the complete data has been replicated to the target, it is then only the changed data to be replicated further, the resulting demands on bandwidth. Initial copy of data storage that is in a remote data center is commonly referred to seeding (planting seeds). When the data is “seeding”, the next replication functions can be run in two modes, namely:
Synchronous Replication Mode
Synchronous Replication Mode allows replication of data exchange in real-time so that the data will be maintained, if the data is currently operational on the disk source, the same writing is also done on the target disk that is in a remote location. The entire process of writing on the source disk and the target disk must be completed first before moving to the next operational transactions and acknowledgment for both if it has been completed. In this replication mode, the need for high system performance should be considered. In addition, the distance between the source disk and the target disk is also the main prerequisite, that the parties involved in the replication mode should be within <100km between the two. The advantage of this mode of replication is to provide consistent recovery and complete for all periods.
Asynchronous Replication Mode
Asynchronous Replication Mode allows the exchange of data buffering in the sense that the data will be put in a ‘temporary receptacle first, then at a certain period will be replicated to disk targets’. The data is replicated to the target disk does not require acknowledgment that the writing of the transactions on the source disk can take place again. Replication mode does not guarantee the data on the two parties involved because if one happens to crash on one side and the data have not been replicated, the data contained on both sides cannot be said as a synchronous data. While this can improve system performance, but has a lot more risk. If this is the case then the recovery, it is quite complicated (do not guarantee the results of data recovery is correct and consistent because there is the possibility of the loss of some data). The advantage of this mode of replication is cost effectiveness.
In addition, based on the place where the replication process is running, the type of replication can be determined suitable for the company’s business needs, namely:
Database to Database replication process that takes place on the database server. The database server will act as a master and then there are several database servers as a slave copy of the database that stores the data. When there is the process of writing the database, the writing will be immediately sent to the master database who will then be replicated by the database server which is a slave. When done reading process in the database, it can be done on all servers available, this course will improve the performance of database systems associated with load sharing. Another advantage of database replication is the availability of a high level, because when the crash occurred on the master database server, the slave server database can take over the work of the master server.
Host to Host Replication Mode
Known also as the replication – based processor. Replication processes running on the source and target systems. Therefore, it may be a dispute between the source and the target system during the process of replication. This occurs because the agent running on each system in the running process tracking changes to data and replication data path is done through an IP connection. Data replication mode runs at the application level or OS level. Host-to-host is the most common mode of replication which is a solution implemented as software. Host-To-Host Replication exploit the resources in the source and target dedicated servers that will have an impact on performance, and then requires that the system is in a remote location should always be up all the time. The significant advantage of this mode of replication is agnostic storage, which means that it can be done pen – deploy early regardless of the type of storage used (internal, external, SAN or NAS ).
Disk to Disk Replication Mode
Disk to Disk Replication mode is running on an external storage device such as a SAN or NAS. This replication mode is normally implemented in a vendor-vendor disk arrays such as IBM, HP, ESDS and others. Each vendor will provide the application software that is compatible with an array of storage. Mostly disk array connections uses fiber channel so that the storage router is needed to improve the ability to connect via a WAN link. Disk-To-Disk Replication devices utilize external resources of storage and is transparent to the host.
Cloud computing also known as virtual server computing, the model computing technologies using computer and network development based on internet. The term “cloud” here is a metaphor for networking parlance Internet and as an associate of the complexity of the infrastructure contained in it. In this computing model, all possibilities related to information technology are provided in the form of “service”, allowing users to access technology services from a provider that “in cloud” without having to have the knowledge and experience of the technology, and not care about the infrastructure that serves the technology.
According to the experts, “Cloud Computing Services is the form in which information is stored in the permanent server on the Internet and is only temporarily stored in the client computer, including PCs, center entertainment, computers in business, the media handheld computers”. Cloud computing is a general concept including concepts such as software services, Web 2.0 and other issues appeared recently, the trend emerging technologies, including its main theme is Internet-based problem to meet the computing needs of the users. For example, the service Google AppEngine application provides conventional business online, can access from a web browser, while the software and data are stored on the server.
The term cloud computing was born between 2007 not to talk about a new trend, but to generalize the direction of information infrastructure which has been taking place since the past few years. This concept can be interpreted in a simple way: the enormous computing resources such as software, services and the services will be located at the virtual server (cloud) on the Internet rather than in computer and family office (on the ground) for people to connect and use whenever they need to. With these services available on the Internet, businesses are not buying and maintaining hundreds or even thousands of computers and software. Most people already use popular cloud services with e-mail, photo albums and digital maps.
The term cloud emanate from application grid computing in 1980, followed by on-demand computing (utility computing) and Software as a service (SaaS).
Grid computing focuses on moving a workload to the location of the computing resources needed to use. A network is a group of servers on which tasks are divided into smaller tasks to run in parallel, is seen as a virtual server.
With cloud computing, computing resources such as servers can be shaped or trimmed from the infrastructure and hardware platform becomes available to perform the tasks.
Virtual server computing is often confused with grid computing, (“a form of distributed computing in which the existence of a ‘virtual supercomputer’, is the inclusion of a cluster computer network, the computer link Soft, coordinate activities to implement the massive task“), computing on demand (utility computing) (“blocks of computer resources, such as processors and memory in a service role. A similar observation for the infrastructure works such as traditional electricity or telephone networks“) and autonomic computing (“computer systems capable of self-management“). In fact, many systems are equipped with grid system, which autonomous features and are marketed like utilities, but cloud computing can be seen as a natural step following the development of model-on-demand network. Many successful cloud architectures have not provided the infrastructure or at specified files or file systems including marketing network peer like BitTorrent and Skype.
The majority of the infrastructure of cloud computing today is a combination of reliable services that are delivered through data centers built on the server with different technologies of virtualization. These services can be accessed from anywhere in the world, in which the cloud is a single access point for all computer needs of customers. The commercial services should meet the requirements of service quality from the customer and are typically given the service level agreement. The open standards and open source software also contribute to the development of virtual server computing.
Thus, before to be able to deploy an application (e.g. a Web page), you have to go buy / rent one or more servers, then a server located in the data center, then this cloud computing allows you to simplify the process of buying / renting it.
Reduce costs: Enterprises will be able to cut costs for the sale, installation and maintenance resources. Clearly, instead of having to appoint an expert to buy servers, install server, server maintenance, now you do not need to do anything than to identify their exact needs and resource requirements. Too convenient!.
Reduce complexity in the structure of the enterprise: Enterprise to produce goods that have both a specialist IT to operate, maintain server is too costly. If you outsource this process, the business will focus on the production of their goods and expertise reduce complexity in structure.
Cloud computing is developed and provided by multiple vendors, including Google, Salesforce as well as the traditional providers such as Sun Microsystems, HP, IBM, Intel, Cisco, Microsoft and ESDS eNlight Cloud. It is used by many individuals and major companies such as General Electric, L’Oreal, Procter & Gamble and etc.
