What Is a Replatform Cloud Migration Strategy?

What Is a Replatform Cloud Migration Strategy?

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.

How Is Replatform Comparable to Other Migration Strategies?

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.

What Are the Advantages of Using Replatform Cloud Migration Strategy?

• Cost-efficiency - replatform is very cost-efficient; it does not require any development project but helps you get superior performance with a lower cost thanks to on-demand pricing.
• Simple scaling - you can simply move your workload or a part of your workload to the cloud, experiment, test, and then scale as your needs grow.
• Cloud-native functionalities - with replatofrm, you quickly access cloud-native functionalities such as auto-scaling and managed storage.

What Are the Disadvantages of Using Replatform Cloud Migration Strategy?

Here are some of the risks and disadvantages of cloud replatform.

• Scope creep - there is a risk of turning a replatforming project into a full-blown refactoring project - this means higher costs and more time. It's very important to carefully manage the scope to prevent unnecessary changes.
• Complicated services - you need to be careful when choosing services for replatform - you must assess the ratio between your investment and gains you receive through the project. If the service is too complicated and requires more changes to your application and specialized staff to maintain it, it may happen that a replatform project is not worth it.

What is the Most Popular Service for Replatform to AWS?

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.

• Simple administration - there is no need for infrastructure provisioning or installing and maintaining database software - everything is done through a console.
• Simple scalability - with a few mouse clicks, you scale your database - with no downtime.
• Availability - Amazon RDS runs on a highly reliable infrastructure and offers features for enhanced reliability.
• Performance - Amazon RDS is built with performance in mind and offers performance superior to any other database.
• Security - database instances can be isolated and connected to your existing IT infrastructure through an industry-standard encrypted IPsec VPN.
• Cost Efficiency - depending on your needs, Amazon RDS service can be charged using On-Demand pricing or Reserved Instances if your utilization is known.

Conclusion

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.
