The What, Why, and How of Cloud Migration

 

What Is Cloud Migration?

A cloud or cloud computing consists of computer services that can be accessed over the internet on-demand. Public cloud, private cloud, and hybrid cloud are the types of clouds. Further, there are three types of cloud service models, SaaS or software as a service, PaaS or platform as a service, and IaaS or infrastructure as a service. And cloud migration is the process of shifting data, workloads, tools, or applications from on-premise infrastructure to the cloud. It also refers to the process of moving data from one cloud to another. Here is why one should migrate to the cloud and the various strategies involved in the process. It can assist you in choosing one of the best cloud hosting providers in India as well.

Why Migrate To The Cloud?

No capital expenditure: With cloud migration, you will no longer have to invest in expensive hardware. Instead, you can pay as you go, thus helping you shift from a capital expenditure to an operating expenditure.

Scalability: The scalability of cloud computing lets you scale up or scale down resources as and when required with changing demands. Hence, you can utilise computer processing or storage resources as needed. Besides, you will have to pay only for the services you use.

Security: Cloud providers give cloud security services top priority, and so you can stay assured of the security of your valuable data. Moreover, your data is more safer on the cloud than on a physical storage device since there is no risk of your device being stolen or damaged.

Reliability: Cloud providers are always up to date with the latest technologies to ensure you get the best cloud backup services, recovery, and network latency. Ultimately, cloud computing offers you the reliability you have been looking for.

Agility: Accessing new services or launching applications can be done quickly with cloud computing as per requirements. Furthermore, all you need is the internet to access services no matter where you are located.

Low maintenance: Since your cloud provider performs the cloud management services, you don’t have to employ a dedicated team for maintenance. Thus, you can focus on your business rather than spending time and resources on maintenance.

Cost-effectiveness: With cloud computing, you can save more as you only need to pay for the resources you use. It cannot be achieved using a physical infrastructure. Also, you can flexibly choose services based on your budget.

How Is Cloud Migration Done?

Cloud migration is a process that requires planning before initiating the process. You have to consider the applications or tools you intend to move, why you are moving them, and how you are going to do it while planning. However, the cloud migration services offered by cloud providers follow specific strategies. Each strategy has its advantages and disadvantages. The different cloud migration strategies include rehosting, re-platforming, repurchasing, refactoring, retiring, and retaining, also known as the 6 Rs of cloud migration. Apart from these, cloud to cloud migration and reverse cloud migration are also performed.
