We already talked about six cloud migration strategies, also called 6R's. Each strategy has its advantages and disadvantages - today, we will go into more detail and talk specifically about the replatform cloud migration strategy.
In general, we can say that cloud replatform is a strategy that enables you to use some cloud benefits with minimum changes to your application code.
Cloud replatform is a cloud migration strategy that sits in between lift and shift and refactoring strategies. While lift and shift is the most simple strategy and enables you to move to the cloud quickly, it does not fully exploit all cloud benefits. On the other hand, refactoring helps you fully exploit all cloud benefits; the problem with refactoring is that refactoring is a lengthy and costly procedure.
Cloud replatform is right in the middle; with minimum code changes, you use specialized cloud services with specific benefits such as performance and scalability.
Here are some of the risks and disadvantages of cloud replatform.
The most popular service for a replatform to AWS is the database. Databases often present a bottleneck in terms of application performance. Having the ability to quickly migrate and deploy new databases in the AWS cloud is very attractive.
AWS offers fully managed specialized database services like Amazon RDS and Amazon DynamodDB. Additionally, we use AWS Database Migration Service for database migration; with this service, we migrate MySQL, PostgreSQL, MariaDB, Oracle BYOL, or SQL Server database to AWS cloud. The service handles the differences between database engines.
As a customer, all you need to do is change the database connection configuration and install additional drivers or database libraries if needed. The benefits you gain are noticeable.
As we said initially, replatform is a cloud migration strategy that sits in between lift and shift and refactor strategies. Generally, it is the best cloud migration strategy if you want to migrate something to the cloud and benefit from cloud-native features like autoscaling - without major changes to your application's code. Replatform is usually a rapid and very efficient process.
The most popular service for replatform to AWS cloud are databases. With Amazon RDS, you can quickly migrate your database to AWS and experience many attractive benefits, such as simple administration, cost efficiency, simple scalability and others.
As AWS Advanced Consulting Partner, we help companies of every industry and size solve their infrastructure problems with cloud migration.
