Organizations looking to migrate their IT infrastructure to the cloud have three types of hosting to choose from: public, private, and hybrid. The major differences among these three are discussed below:
In public clouds, the cloud services and infrastructure of an organization are stored off-site and can be accessed through the Internet. There are plenty of vendors that provide public cloud solutions, such as Microsoft, Amazon, and Google. These companies own and operate the servers, are in charge of implementation and security updates, and ensure that data standards for various compliances are met.
This hosting type is considered the most efficient as organizations only need to access or “purchase” the disk space and bandwidth they need.
In this case, the services and infrastructure are installed, accessed, and maintained in a private network. The data center is located on premises and are operated and managed either by a team commissioned by the organization or a contracted third-party service provider.
This option is best for businesses who value the privacy and security of their data and information.
As the term suggests, hybrid cloud makes use of both private and
public cloud in hosting the organization’s data. It offers the advantages of both hosting types, making it the most popular option among businesses. It does have a downside, however, as there is a need to keep track of multiple cloud platforms to ensure that the cloud is run effectively.
