How to Choose the Right Migration Strategy and Pattern for Your Applications?

• Explain that there is no one-size-fits-all approach to cloud migration and that you need to consider your business goals, application requirements, and cloud readiness before choosing a migration strategy and pattern.
• Introduce the six common migration strategies and patterns, also known as the 6 R’s, and explain their pros and cons:
  • Rehosting: also known as lift-and-shift, this strategy involves moving your applications to AWS without any significant changes. This is the fastest and easiest way to migrate, but it may not take full advantage of the cloud’s features and benefits.
  • Replatforming: also known as lift-and-tinker, this strategy involves making some minor changes to your applications, such as changing the operating system or database, to optimize them for the cloud. This can improve the performance and cost-efficiency of your applications, but it may require some additional effort and testing.
  • Refactoring: also known as rearchitecting, this strategy involves redesigning and rebuilding your applications to leverage the cloud-native features and services, such as serverless, containers, and microservices. This can enable greater scalability, agility, and innovation, but it may be the most complex and costly way to migrate.
  • Repurchasing: also known as drop-and-shop, this strategy involves replacing your existing applications with new ones that are already cloud-ready, such as SaaS solutions. This can reduce the maintenance and operational burden of your applications, but it may also involve some trade-offs in terms of functionality and customization.
  • Retaining: also known as reevaluate, this strategy involves keeping some of your applications on-premises or in a hybrid cloud environment, either temporarily or permanently. This can be useful for applications that are not suitable or ready for the cloud, such as legacy or mission-critical applications, but it may also limit the benefits of cloud migration.
  • Retiring: also known as remove, this strategy involves decommissioning or eliminating some of your applications that are no longer needed or used. This can help you reduce the complexity and cost of your IT portfolio, but it may also require some careful analysis and planning.
• Provide some tips or criteria on how to choose the best migration strategy and pattern for your applications, such as:
  • Assess the cloud readiness and compatibility of your applications using tools such as AWS Cloud Adoption Readiness Tool or AWS Migration Evaluator.
  • Align your migration strategy and pattern with your business objectives, such as reducing costs, increasing agility, or enabling innovation.
  • Consider the complexity, risk, and effort involved in each migration strategy and pattern and how they affect your timeline and budget.
  • Prioritize your applications based on their value, impact, and dependency and migrate them in phases or batches.

How to Plan, Execute, and Optimize Your Cloud Migration Journey?

• Explain that cloud migration is not a one-time event, but a continuous journey that requires careful planning, execution, and optimization.
• Provide a high-level overview of the cloud migration process and its main stages, such as:
  • Discovery and assessment: this stage involves identifying and analyzing your current IT environment, including your applications, data, infrastructure, and dependencies. The goal is to understand the scope, cost, and potential benefits of your migration project and to create a migration plan and roadmap.
  • Design and migration: this stage involves designing and implementing your target cloud architecture, including your network, security, storage, and compute resources. The goal is to migrate your applications to AWS using the chosen migration strategy and pattern and the appropriate migration tools and services.
  • Validation and testing: this stage involves verifying and testing your migrated applications on AWS to ensure that they are functioning correctly and meeting your performance, availability, and security requirements. The goal is to resolve any issues or errors and to prepare for the cutover and go-live.
  • Cutover and go-live: this stage involves switching your traffic and users from your on-premises environment to your AWS environment and decommissioning your old resources. The goal is to complete the migration and start running your applications on AWS.
  • Optimization and innovation: this stage involves monitoring and optimizing your AWS environment and applications to improve their efficiency, reliability, and scalability. The goal is to leverage the AWS services and capabilities to enhance your applications and to innovate with new features and functionalities.
• Provide some best practices and tips for each stage of the cloud migration process, such as:
  • Discovery and assessment:
    • Use tools such as AWS Migration Hub, AWS Application Discovery Service, or AWS Migration Evaluator to automate and simplify the discovery and assessment process.
    • Define clear and measurable migration goals and success criteria and track them throughout the migration project.
    • Establish a migration team and assign roles and responsibilities for each stage of the migration process.
    • Communicate and collaborate with your stakeholders and users and get their feedback and buy-in.
  • Design and migration:
    • Follow the AWS Well-Architected Framework and the AWS Cloud Adoption Framework to design and migrate your applications to AWS following the best practices and principles.
    • Choose the right AWS migration tools and services for your applications, such as AWS Application Migration Service, AWS Database Migration Service, AWS Server Migration Service, or AWS Snow Family.
    • Automate and orchestrate your migration tasks and workflows using tools such as AWS CloudFormation, AWS Systems Manager, or AWS OpsWorks.
    • Document and review your migration process and outcomes and capture any lessons learned or best practices.
  • Validation and testing:
    • Use tools such as AWS CodeDeploy, AWS CodePipeline, or AWS CloudFormation to automate and streamline your validation and testing process.
    • Perform various types of testing, such as functional, performance, load, security, and user acceptance testing, to ensure the quality and reliability of your applications.
    • Use tools such as AWS X-Ray, AWS CloudTrail, or Amazon CloudWatch to monitor and troubleshoot your applications and identify any issues or anomalies.
    • Implement a rollback or recovery plan in case of any failures or disruptions during the cutover and go-live.
  • Cutover and go-live:
    • Choose the right time and method for your cutover and go-live, such as a big bang, phased, or parallel approach, depending on your application characteristics and user expectations.
    • Use tools such as AWS Elastic Load Balancing, Amazon Route 53, or AWS Global Accelerator to redirect your traffic and users to your AWS environment and balance the load across your resources.
    • Use tools such as AWS Backup, AWS DataSync, or AWS Storage Gateway to backup and synchronize your data between your on-premises and AWS environments and ensure data consistency and integrity.
    • Use tools such as AWS Cost Explorer, AWS Budgets, or AWS Trusted Advisor to track and manage your AWS costs and resources and optimize your spending and utilization.
