Forrester survey: 70% "Private Cloud" is a misnomer

If the data center of an enterprise has a highly virtualized environment, users can use to request and access the network port of the virtual machine, as well as a set of methods to track the usage of these resources ... In fact, this is not a real private cloud.

If there is sufficient capacity to provide employees with almost any computing resources they need, and can dynamically increase or decrease capacity, this requires the IT staff to configure the system. Sorry, it's not a private cloud either.

The line between virtualization and private cloud is blurred, according to Http://www.aliyun.com/zixun/aggregation/13534.html, a recent report by >forrester, which says that up to 70% The IT administrator claims that the private cloud is not actually a private cloud.

And why? "If you call a highly virtualized environment a cloud, but it doesn't have one or more of the main characteristics of a private cloud, it is actually setting an unrealistic expectation for users," says James Staten, a Forrester cloud computing expert. If the user discovers that the environment is not configurable, or is not a flexible resource pool, then they will be disappointed.

Most cloud computing experts have a general definition of cloud computing-whether private or public, according to five features listed by the National Technology Standards Agency, including:

-On-demand, self-service

-Extensive network access

-Shared resource pool

-Flexibility to extend resources

-Measuring Service

Without these five features, it is technically not a cloud. Unlike some people, virtualization is not the same as a private cloud, nor is virtualization a necessary technology to support the cloud. VMware Marketing manager Mike Adams says the private cloud contains more advanced management capabilities over virtualized environments.

Andi Mann, vice president of CA Technologies Strategic Solutions, believes that the real problem is not to use these five characteristics to measure whether it is a cloud, but it is the ability to provide services to users appropriately. "80% of the cloud is good enough, people really care about the business value, what you call it, you care about your customers, your business users can get the resources they need." ”

Perhaps the enterprise does not need resilient scalability because there is already a static workload. The cloud has other benefits, self-service, debit, extensive network access, and shared resource pools. But Staten says fundamentally IT administrators are afraid of the cloud. The virtualization experts in the past are the ones who control everything, and when they need resources, they allocate capacity. Now, they think of the cloud as a threat to this pattern because users can help themselves and expand resources dynamically. So what can virtualization experts do?

Staten said the idea was wrong. There is a lot more to be set up by IT administrators to ensure that the cloud has an option directory available to the user, perfecting the appropriate security protocols, resource availability, and virtualization components. Administrators must accept this idea, because if they do not, then users will access the resources themselves, but the dreaded "shadow it".
