By migrating to AWS, you’re not just moving workloads – you’re gaining a platform to reimagine what’s possible, from automating operations to launching groundbreaking products.
AWS Cloud Migration Strategies
Crafting an effective AWS cloud migration strategy is key to success. AWS offers six tailored approaches, known as the “6 Rs,” each designed to meet specific business needs and technical requirements:
- Rehost (“Lift and Shift”)
Swiftly move applications to AWS without code changes using AWS Application Migration Service (MGN). Perfect for legacy systems like Windows servers, this approach minimizes disruption while unlocking AWS’s scalability and cost benefits, making it ideal for tight timelines. - Replatform
Optimize applications during migration for enhanced performance, such as shifting an on-premises database to Amazon RDS. This strategy strikes a balance between speed and modernization, enabling businesses to leverage AWS’s managed services without extensive reengineering. - Refactor / Rearchitect
Transform applications into cloud-native architectures using AWS Lambda for serverless computing or Amazon ECS for containerized workloads. Though resource-intensive, this approach maximizes scalability, resilience, and cost efficiency, future-proofing your IT stack. - Repurchase (Move to SaaS)
Replace legacy software with AWS-hosted SaaS solutions, such as Salesforce or Workday, to reduce maintenance overhead and accelerate deployment. This approach streamlines operations, allowing teams to focus on core business priorities. - Retire
Identify and decommission redundant or obsolete applications during the assessment phase, using AWS Migration Hub to streamline the process. Retiring unused systems cuts costs and simplifies your IT portfolio, freeing resources for strategic initiatives. - Retain
Keep mission-critical applications on-premises with AWS Outposts, which extends AWS infrastructure to your data center. This hybrid approach ensures seamless integration with AWS services while addressing regulatory or latency requirements.
Step-by-Step AWS Cloud Migration Process
The AWS cloud migration steps provide a structured roadmap to ensure a smooth and successful transition. Here’s a detailed breakdown of the four-phase AWS cloud migration process:
Step 1- Assessment and Planning
Begin by taking stock of your IT environment with AWS Migration Evaluator, which catalogues applications, servers, and databases. Use AWS Application Discovery Service to map dependencies, revealing how workloads interact.
This phase also involves assessing cloud readiness, prioritizing low-risk applications, and building a business case with cost projections. A thorough assessment lays the groundwork for a tailored migration plan, minimizing surprises down the road.
Step 2- Mobilization and Preparation
Set the stage for migration by creating a secure, scalable landing zone with AWS Organizations, Virtual Private Clouds (VPCs), and IAM policies. Implement AWS Control Tower to establish governance for multi-account environments, ensuring compliance and cost control.
Configure essential tools like AWS Migration Hub for centralized tracking and Amazon CloudWatch for real-time monitoring. This phase is about building a rock-solid foundation for your AWS journey.
Step 3- Migration Execution
Execute the migration with precision, using AWS MGN for lift-and-shift workloads or AWS Database Migration Service (DMS) for seamless database transfers. Conduct rigorous testing with AWS CloudFormation to validate performance and functionality.
Validation ensures applications perform as expected in the cloud, with minimal disruption to users. This phase transforms planning into action, bringing your workloads to life on AWS.
Step 4- Post-Migration Optimization
After migration, fine-tune your environment for peak performance. Use Amazon CloudWatch to monitor application health, AWS Compute Optimizer to right-size resources, and AWS Budgets to manage costs effectively.
Continuous optimization ensures your AWS environment remains efficient, secure, and aligned with business goals, delivering long-term value.
Essential AWS Cloud Migration Best Practices
To make your AWS cloud migration a triumph, follow these AWS cloud migration best practices:
Start with Low-Risk Applications
Begin your migration journey by focusing on non-critical workloads, such as internal tools, HR systems, or staging environments.
This strategy helps build confidence and refine your migration processes without impacting core operations. AWS Migration Evaluator can pinpoint low-complexity workloads, ensuring minimal disruption. By establishing a solid foundation early, your teams gain the experience needed to handle mission-critical applications more effectively and with lower risk.
Maximize Automation for Efficiency
Harness the power of automation with AWS Server Migration Service (SMS) or AWS MGN to streamline virtual machine and application migrations, slashing manual effort and errors.
AWS CloudFormation enables infrastructure-as-code, ensuring consistent, repeatable setups across development, testing, and production. Automation accelerates timelines, reduces costs, and ensures precision, making your migration a well-oiled machine.
Establish a Cloud Center of Excellence (CoE)
Build a CoE to centralize cloud expertise, drive governance, and align migration with strategic goals. Populate it with cloud architects, DevOps engineers, and security specialists, and conduct regular AWS Well-Architected Framework reviews to optimize performance, security, and costs. A CoE transforms migration into a disciplined, business-driven initiative, ensuring long-term success on AWS.
Adopt CI/CD and DevOps Practices
Embrace AWS CodePipeline and CodeDeploy to enable continuous integration and delivery, accelerating deployments and fostering agility. AWS CodeStar enhances team collaboration with Git-based workflows, streamlining development cycles.
By embedding DevOps principles, you create a culture of rapid iteration, ensuring applications evolve seamlessly post-migration and deliver value faster.
Perform Comprehensive Testing
Leave no stone unturned with User Acceptance Testing (UAT), performance, and security tests, leveraging AWS CloudFormation for automated validation and AWS Fault Injection Simulator to stress-test resilience.
Simulate real-world workloads with AWS Load Testing services to ensure scalability under pressure. Thorough testing catches issues early, ensuring a flawless user experience and rock-solid reliability.
Develop Robust Rollback Strategies
Safeguard your migration with AWS Backup for automated, point-in-time recovery and AWS MGN’s continuous data replication for a live fallback environment.
These tools minimize downtime and ensure business continuity if issues arise during cutover. A well-crafted rollback plan instils confidence, allowing you to migrate boldly while mitigating risks.
Engage Stakeholders Early and Often
Rally business and IT stakeholders from day one to align migration with organizational priorities, from cost savings to customer satisfaction. AWS Migration Portfolio Assessment generates compelling business case reports, showcasing ROI to secure buy-in and funding.
Regular stakeholder engagement fosters transparency, builds trust, and ensures your migration delivers measurable business impact.
