Cloud migration is a critical step for businesses looking to scale, reduce costs, and improve agility. However, without proper planning, migrations can lead to downtime, data loss, and budget overruns.
Choose between rehosting (lift-and-shift), replatforming, or refactoring. Each approach has different timelines and benefits.
Inventory all applications, databases, and dependencies. Document performance baselines and current resource utilization.
Compare AWS, Azure, and GCP based on your specific needs, pricing, and service offerings.
Use cloud calculators to estimate monthly costs. Factor in data transfer, storage, and compute resources.
Plan phases: pilot migration, core services, and remaining applications. Allow buffer time for testing.
Create cloud-native architecture diagrams. Plan for high availability, disaster recovery, and security.
Configure IAM roles, encryption at rest/in-transit, and ensure compliance with industry standards.
Set up logging, alerting, and performance monitoring before migration begins.
Create complete backups and test restoration procedures. Have rollback plans ready.
Migrate a non-critical application first. Document lessons learned and refine the process.
Follow the planned order, prioritizing based on business impact and technical complexity.
Test functionality, performance, security, and integration with other services.
Right-size instances, implement auto-scaling, and optimize databases for cloud efficiency.
Ensure your staff is trained on cloud operations, monitoring, and troubleshooting.
Use cloud-native tools to track costs, performance, and security posture. Optimize regularly.
