Consider migrating from home to a remote location to get better prospects. You will plan your move, choose a great place to stay, and then move your belongings and furniture to a new place. Once moved, it will be installed and examined if you have everything that has been transferred. This is the same case when migrating to the cloud. Now let’s look at the different stages involved during migration and also the different types of migrations.
What is cloud migration?
Cloud migration is a plan or process in which data and applications are moved to the cloud. You migrate your digital business operations through this.
What are all the steps in the migration process?
Migration is not a one-step process. Migration can be a complex process depending on the size and complexity of your applications. Here we mention some of the fundamental steps of the migration process.
Migration planning: Before you plan your migration, you need to have a clear goal about the reason for the migration and the strategies to use. You need to calculate your cloud server requirements based on the current resource requirements of your application. This is because you do not have to pay extra for what you do not need. You can turn to migration specialists at this stage to determine all dependencies and requirements.
Choose your cloud provider: Once you plan to migrate, you can decide which cloud environment to adopt. It can be a public cloud, hybrid cloud, private cloud, or multi-cloud (or services such as Google, Azure, or AWS). Depending on future requirements and needs, you can decide.
Application and data migration: With the help of experts and a tailored plan, you can migrate your data and applications with ease. Just take into account all security, data and backup issues when migrating.
Migration validation: We can only call the migration a success if it delivers the desired performance. You can compare performance before and after migration from a technical and business perspective.
What are all types of migration processes?
Rehosting: The rehosting strategy is also called lifting and moving because it involves lifting servers or applications from the current hosting environment and transferring them to the cloud infrastructure. While rehost carries exact copies of your current environment without making any changes. This saves money for retraining staff on a new system. This strategy usually starts when companies initially think about migration
Replatforming: Replatforming is nothing but rehosting. With this strategy, we migrate applications and their components to a cloud-managed platform without having to change the core application architecture. You can increase or decrease your company’s resources and capabilities at any time by adopting this strategy.
Buyback: By adopting this strategy, you abandon the old app platform and buy new platforms. It has such disadvantages as loss of familiarity with the existing code and retraining of employees.
Refactoring: Refactoring is also called redesign where you rebuild applications from scratch. Although this is the most expensive method, it is the best option when you want to improve services. Companies often adopt it when their current environment is difficult to improve.
Retreat: As the company plans to migrate applications to the cloud, it lists its applications. They check that everything needs to be migrated and also understand the use and cost to the business. If the company believes that the application is not quite worthy of migrating, you can simply reduce its size and remove it from the list. This not only simplifies costs, but also allows an organization to promote scalability and efficiency
