Migration Strategies: AWS Consultant’s Deep Dive Into Cloud Migration

As an AWS consultant, I can help you learn everything there is to know about making the switch to the AWS cloud. Several of your applications and data can be moved to the cloud with the help of AWS’s many services and capabilities. Let’s take a look at the AWS services that work in tandem with some of the most important migration approaches.

1) Lift and Shift (Rehosting)

With little adjustments, this technique moves your applications from on-premises infrastructure to AWS. The objective is to move your systems to the cloud as rapidly as possible without losing any functionality.

Features of Amazon Web Services:

•    Automates the process of moving VMs from on-premises hardware to AWS EC2 instances with the AWS Server Migration Service (SMS).
•    To help in the process of moving databases to Amazon’s Relational Database Service (RDS), AWS offers the Database Migration Service (DMS).

2) Replatforming (Lift, Tinker, and Shift)

Taking advantage of cloud-native features while minimising fundamental architecture modifications, replatforming optimises your applications during migration.

Features of Amazon Web Services:

•    Elastic Beanstalk, one of AWS’s services, simplifies application deployment, operation, and scalability.
•    AWS Lambda is a serverless computing platform that allows applications to run without the need to provision or manage any underlying servers.
•    Support for moving data from on-premises databases to AWS managed services like Aurora or Redshift is provided through the AWS Database Migration Service (DMS).

3) Refactoring (Re-architecting)

Refactoring entails making significant modifications to your application design to fully harness the cloud’s benefits. Scalability, performance, and cost optimisation may all benefit from the additional work involved in this approach.

Features of Amazon Web Services:

•    Elastic Kubernetes Service (EKS) on Amazon Web Services is a managed Kubernetes service designed for use with containerized software.
•    Microservices architectures and event-driven apps find a natural home with AWS Lambda.
•    To create serverless workflows, you can use the AWS Step Functions orchestration service.
•    High-performance applications can benefit from Amazon DynamoDB, a fully managed NoSQL database service.

4) Repurchasing (Retiring and Replacing)

This technique entails retiring legacy systems and replacing them with commercial software or cloud-based SaaS solutions.

Features of Amazon Web Services:

•    The AWS Marketplace provides access to numerous commercial applications and hosted services.
•    The AWS SaaS Boost framework is used to create and update SaaS applications.

5) Retaining (Hybrid Architecture)

It may be necessary to keep some systems on-premises while transferring others to the cloud. With a hybrid architecture, you may take advantage of the cloud while still utilising your current setup.

Features of Amazon Web Services:

•    With AWS Direct Connect, you may link your on-premises data centre to the cloud provider.
•    With AWS Outposts, you can bring the power of the cloud to your own data centre.

Here are a few cloud migration approaches and the related AWS services that can help ease the transition. Your needs, the architecture of your applications, and your business objectives should all guide your decision. Working with an AWS consultant or partner to determine your specific migration requirements and craft a custom migration strategy is highly recommended.
