The U.S. National Institute for Standards in Technology, (NIST) defines cloud computing, which is acceptable to the industry. According to research firm Gartner, there is still a lot of “drain” in the market, or confusion about the precise definition of the technology. Gartner Firm has released a list of five misconceptions about the cloud.
YOU KNOW WHAT IS CLOUD?
Poll: One-third of people around the world believe that “cloud” is related to the weather.
ALL PR? Cloud computing is one of the most hyped terms.
First, let’s focus on the cloud. NIST defines five characteristics of cloud computing: The allocation of resources on-demand, access to a broad network, pooling of resources, elasticity or the ability to rapidly expand, and pay only for services consumed.
According to an analyst firm Gartner, the adoption of cloud services is stimulated by “rapid penetration of virtualization” the company and the ability to improve the delivery of IT services. But ads are usually appeared with confusing definitions. Gartner has given one simple tip for confused users of IT services. According to Gartner, IT organizations do not need to pay attention to the ads and focus on private cloud computing projects that have the most sense for the business. Here are a few misconceptions about the nature of cloud computing, which exist in the industry:
The Cloud Computing Is Not Just Virtualization
Creating a private cloud is not just a setting on the server hypervisor. While virtualization is a key component of cloud computing, by itself it is not a cloud. Virtualization technology allows organizations to consolidate and provide the resources that are an integral part of determining the NIST. But for its technical definition of a cloud environment than self-service and scalability of these resources are necessary, and other properties as well. In contrast, public or hybrid cloud, private cloud is used by a single organization due to the resources that they require.
Cloud Is Only A Means To Save Money
One of the biggest misconceptions of IT organizations is that the cloud will save money. It can do this, but this is not its characteristic property. Automation, an important element of a network of private cloud can be a serious investment for many IT organizations. As a result, they are able to better redistribute the resources, and this may allow some organizations to lower their overall capital costs for new equipment, and thus save money. But according to Gartner, the main impetus making cloud model should not be an opportunity to save money, but its greater flexibility and dynamic scalability, which can reduce the time to market.
Private Cloud Solutions Is Not Always At The Customer’s Site
Most of the private cloud is associated with an internal data center organizations, and public cloud – with a third-party service provider. However, many suppliers will sell private clouds, located outside the territory of the customer, which involves the allocation of resources for a single user, multi-user without a resource pool for general use. According to Gartner firm, private cloud computing is defined as confidential and no accommodation, the property relations and administration. However, be careful with the different definitions of security given by the different providers. For example, some may be placing their data center in a third-party service provider with colocation service, or can combine users resources, and share them via VPN. Gartner firm advises to carefully consider offers of cloud services that are placed outside of the customer.
Private Cloud Is Simply An Element-Level Infrastructure
Often, private cloud computing represents itself as a virtual service infrastructure. However, there are other private cloud implementation, especially in software and platform levels, and a growing number of other forms. According to Gartner firm, the level of IaaS is the fastest-growing segment of the cloud, but it may not necessarily be the most important.
According to Gartner firm, IaaS provides a usable form only with low-level data center resources, and does not alter the nature of IT. And for the users, it is at the level of the platform as a service (PaaS), organizations can create custom applications designed for cloud infrastructure. There are also private and public options for PaaS, where application development services are located in your own data center or in a specialized environment provided by the supplier.
It May Not Always Be Private
For many organizations, the private cloud is a natural step in the direction of the cloud network. It allows you to enjoy the benefits of the cloud as the flexibility, scalability and performance, and at the same time eliminates some security problems, real or imagined, that are associated with the use of a public cloud. But as the market develops, organizations will increasingly use public cloud resources. Service agreements and precautions will be developed, and the impact of power outages and downtime will be reduced to a minimum. According to forecasts by Gartner, over time, most private clouds will turn to hybrid clouds, in the sense that they will use public cloud resources. This means that your current private cloud may be hybrid cloud tomorrow. With the private cloud, IT organizations are positioning themselves as a broker of all corporate services, whether private, public, hybrid or traditional. The private cloud, which is converted into a hybrid or public, may reserve the ownership of self-service portal, and therefore, users and interface.
