What is Private cloud computing?
Private cloud computing and public cloud computing are two most popular types of cloud computing which delivers the similar flexibility and scalability to general users. But in contract to public cloud, private cloud infrastructure is operated solely for a single organization and data under private cloud is only accessible to that organization only. This helps organization with sensitive data attain greater control and privacy and reduce the risks of security like information thief, leak, or nonrecognized access.
Private cloud computing is a new wave in business computing that offers several benefits resulting in a total lower cost for any type and size of company or organization.
The most compelling benefits of private cloud computing
1. Elasticity and scalability
Under private cloud computing, the supply of cloud is always available and can be offered on demand thanks to the ability of increasing computing resources unlimitedly. This characteristics and the charging model of pay as you go, which means you only have to pay for the amount of computing instance in the amount of time you used them, create the best economical and scalable service as well as provide consumers the opportunities to reduce business costs.
2. Better security and privacy
Private cloud computing uses techniques that deny accesses made from connection out of the customer organizations firewall. This helps keep the instance as well as the data of that single organization private and safe from online security threats.
3. Greater control over cloud space
Since the cloud space under private computing is only accessible to a single customer, this cloud can be modified, configured and managed to comply with the need of that customer. However, there is one thing should be noticed is that, this greater level of control of private cloud computing will remove some cost benefits as it is often more expensive than public cloud computing.
4. Cost and resource efficiency
Due to increasing management cost and smaller economy of scale, private cloud computing may not be as cost effective as public cloud computing. However, it does improve the allocation of an organizations resources by minimize the investment into unused capacity, thereby offering customers more cost saving benefits than the traditional LANs
The downsides of private cloud computing
There is one thing cannot be denied is private cloud computing has it downsides alongside the benefits. As a result of sending data to a third party serve and being rely on the organization that implements private cloud service, customers are passive in their own running or managing IT problems.
Private cloud computing providers
It is not true that every private cloud computing providers are offering the same benefits scalability, flexibility, cost savings, high security, control. Following are some high performance vendors that should be taken into consideration when choosing a private cloud computing provider
Rackspace Private Cloud (Powered by OpenStack)
