Cloud computing is the result of technology’s rapid evolution. Cloud can be offered in two types: The Private Cloud and the Public Cloud. Cloud offering as a service over the Internet is known as the Public Cloud. A Private Cloud is cloud deployment where the business IT team manages the cloud. To choose between a public cloud and private cloud, it is important to understand the differences between the two. The following outlines the differences between a Public Cloud and Private Cloud.
With a public cloud, users are normally charged on a monthly basis. Users pay for the usage per Gb. It is based on the on-demand storage scalability. The hosting provider has the responsibility of managing the infrastructure and pool of resources. Users are not required to buy hardware or software. With a public cloud, back-up on a single laptop or deploying an application is quite simple. As users need increase, they have the ability to lease more capacity and there is linear cost scaling. The length of time to store user data may affect the selection of a public cloud, particularly for businesses that have a high quantity of data. The longer the data stays on the public cloud the more increase in costs.
Since public cloud is accessed via the Internet, there is a limitation to accessibility. As well, because there is bandwidth limitations associated with the Cloud, problems with sufficient bandwidth could be a potential problem. It is helpful to select the appropriate bandwidth resources to avoid any problems.
Private clouds are licensed like businesses. They are deployed and accessed over the Ethernet LAN at high speed. It is quite easy to deploy the cloud architecture. The Private cloud is created using cloud software operating on a hardware that has been provided by the cloud hosting company. Users can download the software and the private cloud can be up and running within an hour. Storage is completely controlled and retained by the client and not shared with anyone else. Private cloud allows for high scalability which permits users to make additions of servers to the current architecture that is completely managed by the users. The duration of time for data storage is very fast and each node addition boosts performance. Replication of files to multiple nodes gives each node the ability to serve independent requests. Private clouds can be built at a budget-friendly cost.
Choosing between the Public Cloud and Private Cloud involves having a general understanding of your data requirements and usage. The more data and usage you require, the more likely you will need a Private Cloud.
