In this global business era, cloud technology is capable of providing cloud services anytime and any place. Whether we like it or not, cloud computing is here to stay for good and for the benefit of society as a whole.
The process of transferring on-premise hosted services such as databases, web applications, file systems, network drives and so on to the cloud is known as cloud migration. It is similar to physical relocation, except that instead of packing and transferring tangible objects, it entails moving data, apps, and IT processes from one data centre to another. Cloud migration, like moving from a smaller to a larger office, involves a significant amount of planning and preparation, but it is usually well worth the effort, resulting in cost savings and increased flexibility.
Types of cloud migration strategies:-
Lift & Shift: The simplest cloud migration path is lift and shift. It simply means that you can transfer apps, virtual machines, and server operating systems from your present hosting environment to public cloud infrastructure without making any changes.
Replatforming: Re-platforming entails OS optimizations, application API updates, and middleware upgrades.
Replacing: You switch from a proprietary programme to a cloud-based platform or service under this strategy. Typically, this entails ending your current licence agreement (or allowing it to expire) and replacing it with a new platform or software as a service.
Refactoring: This solution entails rethinking how an application is designed and developed, usually with the help of PaaS’ cloud-native characteristics. This is frequently motivated by a strong commercial need to add features, size, or performance to the application that would be difficult to do in its current context.
The benefits of cloud migration:-
Reduced operating costs: Companies that deploy assets to the cloud save huge costs of setting up and managing their own data centres. This drastically minimises the amount of money spent on hardware and in-house IT.
Faster speed to market: Cloud vendors offer pre-built automation tools and capabilities that allow businesses to shorten deployment cycles and release new products more quickly.
Scalability and implementation: On-premise systems were built to handle peak loads and only used about 20% of their capacity. Cloud systems allow businesses to utilise only the resources they require at any given point in time.
Reducing upfront project costs: Computing platforms provide flexible payment alternatives, such as “pay-as-you-go,” which reduce upfront licence and hardware costs.
