Last week we talked about one of the most popular cloud models. Public cloud solidified the cloud as a viable storage solution. However, with it, several issues became more evident. Security and privacy concerns, were, and still are at the forefront of Cloud Computing. The term ‘Public’ began to have a negative connotation, forcing many companies to seek different solutions.
What is the Private Cloud?
Private cloud, is a model that consists of a separate and secure cloud environment, where, only the client can operate. Similar to other cloud models, private cloud provides cloud computing services in a virtualized environment, sharing various computing resources. What separates the private cloud from other models, is that, only a single organization has access to the resources. Inherently, private cloud offers more control and privacy to organizations that can afford it.
As we have mentioned before, cloud computing is at times hard to define, due to the broad spectrum of services it can provide. Private cloud services, are often categorized by the features offered to the client. Some of these features include: an isolated pool of resources for the sole use of one organization and, a higher level of network security. This pool of hardware, can also be hosted internally or externally.
The private cloud model, is similar to the more traditional local access networks (LANs) used in the past by many companies. Except, private clouds benefit from a virtualized environment.
The benefits of private cloud:
More security and privacy: public clouds provide today a significant level of security. However, if you can afford to take advantage private clouds, you will benefit from an exclusive pool of resources. The restricted access it provides, makes sure that your company operations remain confidential.
More Control: since its only accessible by one organization, there is more freedom configuring and managing the cloud. This level of control, comes at the cost of not having centralized management. Scaling cloud resources takes more time.
Improved reliability: even if the resources are hosted internally, the virtual operating environment, provided by private cloud means that the network will be more resilient to failures. For example, virtual partitions can pull resources from the remaining unaffected servers. In the case of private cloud hosted with a third party, the organization can benefit from the physical security around and within data centers.
Public and Private clouds offer many benefits, but what if you could use both? Hybrid Cloud has been gaining more traction among cloud users. Specially, because it provides advantages of both public and private clouds. Next week we will explore what Hybrid and it is becoming so popular.
