When a cloud provider offers cloud service to multiple customers, it is called a public cloud. It serves on a remote server managed by the provider. Customers can access that cloud over the internet. Multitenancy is a very common word when it comes to public cloud. Sometimes, the same physical server is shared by multiple organisations and then it is called multitenancy. It happens when multiple customers of a cloud provider access the same server. The same server is used to process two different applications along with storing data from two different companies.
Public cloud vs private cloud
A private is the one which is used to process the application of only one company or user. This cloud stores the data of that user only. Any part of this cloud is never shared by any other user. On the other hand, a public cloud is shared by multiple users. Their applications are processed and data is stores in the same server and sometimes it happens at the same time. In a public cloud the data and application of one user remain hidden from other tenants. Professionals like We Have Servers help people to decide which cloud will be best suited for their usage.
Benefits of public cloud
Public clouds cost less than private clouds. It is a great way to cut down IT operation costs. Outsourcing helps as the provider can handle it more efficiently ad you have to spend lesser than a private cloud. For small businesses the security of a private cloud helps them to keep the data safe. There is also no need to spend time on managing servers.
Cons of public cloud
Businesses that need to meet regulatory compliance standard, might have issues with multitenancy. Though the risk of data leakage is very small, it might become a big problem for some businesses. The security measures of a public cloud may not be enough for some users.
