The organizations have various methods to deploy cloud service resources namely- public private and hybrid cloud. Each of the three has its own set of advantages related to their performances, cost-effectiveness, scalability, cloud security practices and reliability. It is up to the enterprises to decide which of the three should be deployed based on the individual requirements. This blog gives you an insight into what is public private and hybrid cloud and the differences between them in cloud computing technology.
Nowadays, cloud computing is a necessity for businesses. Cloud storage space and servers are now managed by third-party cloud service vendors and supplied over the web. Microsoft Azure, Amazon Web Services, Google Cloud, IBM Cloud are some popular examples of public cloud service providers. It is totally their responsibility to handle the cloud infrastructure like hardware, software and other supporting systems. The benefit of cloud computing is that enterprises can share their storage, hardware and network details with other cloud accounts or partners. Online accounts and services can be managed by web browsers. The online email, online storage, online Office applications and the development and testing environments are serviced by the public clouds.
The private cloud can be hosted in two ways that are:
Hybrid cloud is a combination of public and private cloud. In this, higher efficiency can be achieved by migrating the data and programs from public to private or private to public; thus achieving higher flexibility with deployment options. Public cloud can be used to store high volume data but with fewer security requirements like web-based email clients. The private cloud can be used to store confidential data and critical operations like customer personal information. In the hybrid cloud, there is an option of cloud bursting. Here, the enterprise resources and software works on the private cloud till there is an absolute necessity or high demand to ‘burst through’ the public cloud. This helps the enterprise to acquire more computing resources on the cloud.
Public private and hybrid cloud are very useful when enterprises understand their cloud computing requirements. The enterprises have to understand the technical concepts of the three and select the best. The security of data in the cloud cannot be compromised even when one among the three is selected. It is best that the enterprises go in for CASB solutions that add an extra layer of security into the confidential data; thus rendering them safe and secure.
