The Ultimate Guide to AWS Cloud Migration Checklist

Description of the image

Do you know how complex migrating your application to the AWS cloud is? In today's competitive world, every business has to take this step for digital transformation. With the right checklist, you can simplify the daunting task of AWS cloud migration.

The path to Amazon Cloud becomes clearer through strategic planning and execution.

Application Review and Architecture Preparation

The AWS migration checklist begins with a thorough app review. It is important to check if the app can be migrated to the AWS cloud. It can be done by the following checklists:

  • Identify Business Drivers: Consider all the benefits and drawbacks of transferring app data to the Amazon AWS cloud. Determine the business motives behind the action.
  • Cost Estimation: Due to expensive cloud services, create a budget using a cost-handling tool by calculating the cost of scaling, storage, computing, and data transfers.
  • Assess Application Components: Determine in-house components in your app that are made to be deployed or require refactoring. Set a plan for migrating those components whenever needed.
  • Data Security: Determine the endpoints for data transfer, ensuring safe input-output operations. Decide to transfer data through a dedicated fiber or the public internet.
  • Check Databases: The app database can either be migrated to Amazon Aurora or the SQL server ported to EC2.
  • Analyze Dependencies: Using the App Discovery service by AWS, understand the dependencies and workflows between the components to identify potential issues.

During the initial step of cloud migration, organizations find the reasons to refactor it and make it ideal for web use. If it is a massive investment for the business, extra time and effort are required for application optimization.

Find the Right Hosting Environment

After knowing the resources and operational demands for migration, you must find a way to host the app on the cloud correctly. Consider the further checklist to differentiate your hosting choices.

  • Create an Infrastructure Plan: Check if the app needs Amazon VPC or multiple tenant instances for deployment. For migration, it is recommended that a multi-user account be developed in the AWS landing Zone.
  • Choose Instance Types: Your instances should fulfill the app's scaling needs. For better execution, the team should consider AWS's high-level options, like Lambda.
  • Automated Scaling: Scale your application automatically, considering the resource consumption and costs. Adjust the limit manually to plan to scale cost-effectively.
  • Create Storage Space: Use Snowball to shift massive data to the AWS web. Using storage lifecycle management, you can move data within different storage tiers or vice versa.
  • Pick the Hosting Environment: Considering the geographic restriction, pick the perfect hosting environment for your application to minimize latency and easy deployment.

App Deployment

While transitioning from server maintenance to standardized, automated instances, companies must consider automated tasks and IaC. Using a deployment package and integrating agile strategies, migrate your application successfully to the Amazon cloud. Follow the checklist to ensure you are deploying the app correctly. 

  • Migrate the App Components: Use CloudEndure, VMware, database, and server migration services by Amazon AWS to migrate multiple components of your application.
  • Use CD/CI Pipeline: With the help of these pipelines, you can deploy the app and related updates to the resources. Amazon AWS provides CodePipeline along with CodeBuild with independent pipelines like the Jenkins pack of tools for deployment.
  • Use IaC Templates for Configuring App Infrastructure: For rapid deployment, use third-party tools like HashiCorp's Terraform, a fusion of CloudFormer and CloudFormation templates.
  • DevOps Execution: It will restrict AWS web migration if your app is created using a waterfall development model.

Operations and Migration Support

After a successful AWS web migration, the app life cycle begins. It includes monitoring performance, resource management, or incident detection to prevent security issues. Follow the following checklist to monitor the app's overall performance after deployment.

  • Track App Performance: Using third-party tracking tools like CloudWatch, monitor the performance parameters and ensure the components are updated well enough for cloud-based services.
  • Track Infrastructure Resources: AWS tracks and ensures availability, maintaining the performance of the infrastructure. The team determines when the app is experiencing issues and incorrectly configured instances.
  • Security Measures: Security parameters change automatically when the app shifts to AWS web. Check the status of firewalls and how it is managing traffic. Keep your application secured by regular vulnerability scans. For log handling, create a centralized-based log management system.
  • Handle Incident Response: Administrators manage and troubleshoot the servers depending on the on-premises operations. Utilizing on-demand resources will roll back all the issue-causing updates.
  • Curb Sprawl: After cloud migration, check the deployment operations and scaling constraints to adjust them promptly to control your budget. If there is unexpected usage, keep checking the bills and app performance.

Project Management

The final step of Amazon web migration is project management, including application evaluation and cost control. It is important to keep revising the configurations to monitor the app performance and handle the budget. Once your app is successfully deployed, consider these checkpoints for further project management. 

  • Long-term Cloud Migration Goals: To manage your account and expenses for the long term, plan your goals. Check whether cloud adoption is centralized and how organizations make further project decisions.
  • Provide Staff Training: Assessing and training your staff skills in AWS tasks is important. Train your staff regarding present improvements and handling future goals.
  • Manage Costs: Utilize cost simulations to create your budget and keep your spending under control.
  • Pick Necessary Tools: The Ultimate Guide to AWS Cloud Migration Checklist tools to understand the team requirements and provide training to administrators accordingly.

What are the types of Cloud Migration Strategies?

1. Rehost (Lift and Shift)Shifting applications to the cloud with minimal changes.
2. Replatform (Lift, Tinker, and Shift)Optimizations without changing the core architecture of the applications.
3. Repurchase (Drop and Shop)Replace the current application with a new native solution.
4. Refactor (Re-architect)Redesigning and rewriting applications to better fit the cloud environment
5. RetireRemove applications that are no longer useful or needed.
6. Retain (Revisit)Keeping certain applications on-premises due to business.

Final Thoughts

Proper planning and execution are essential for adequate cloud migration. However, you can ease your journey by using the detailed checklist. Navigate each process in-depth and ensure you meet all the requirements before proceeding to the next step.

Successfully covering each step will move your app to the AWS cloud smoothly. After migration, keep monitoring the app's performance and controlling unnecessary expenses. Migrating your application to the AWS cloud transforms your business to another level, leading to future growth. Go through all the phases of cloud migration and scale your application cost-effectively.
