Many enterprises are considering migrating from VMware to AWS. In our previous blog, we covered the importance and benefits of this migration. In this blog, we will detail a three-step process explaining how to migrate successfully from VMware to AWS and what can be done to ensure smooth operations after the migration is complete.
VMware to AWS Migration Methodology in Three Steps
Evaluating the current infrastructure
Assessment of your current VMware environment is the first critical step in this migration journey. This process involves:
- Inventory Analysis: Documenting and cataloging all the VMs, applications and dependencies across your VMware environment.
- Performance Metrics: Documenting data related to resource utilization, including CPU, memory, storage, and network usage.
- Compliance Requirements: Identifying industry-specific regulations or internal policies that could impact the migration.
- Application Dependencies: Understanding how different applications interact to ensure minimal disruption.
This assessment is crucial for making informed decisions and ensures that you have detailed insights into the current state of your existing infrastructure as you progress in this migration process.
Determining the migration path best suited for your needs
Based on the assessment results, you can decide on the most suitable migration path. AWS offers several approaches for migrating VMware workloads as part of its 6R strategy, which comprises Rehosting, Replatforming, Repurchasing, Refactoring, Retiring, and Retaining. For the VMware to AWS migration scenario, the following three approaches are most relevant.
- Rehosting (Lift and Shift): This approach involves moving applications to AWS with minimal changes, ideal for organizations looking for a quick transition.
- Replatforming: This strategy involves minor optimizations to take advantage of cloud capabilities without changing the core architecture.
- Refactoring: This approach involves re-architecting applications to be cloud-optimized for organizations looking to fully leverage cloud-native features.
The choice between these strategies depends on application complexity, time constraints, and desired cloud benefits.
Implementation
You can start executing the migration now that your strategy is in place. In this phase, your data, applications, and services are migrated from VMware to AWS. You must have a good rollback plan to counter risks and issues encountered during the migration process. Thus, constant monitoring becomes essential to ensure the migrated workloads operate as expected post-migration. This stage usually includes:
- Pilot Migration: Starting with a small, non-critical workload to test the process and identify potential issues.
- Data Migration: Transferring data to AWS using tools like AWS DataSync or AWS Snowball for large datasets.
- Application Migration: Moving applications according to the chosen strategy (rehost, replatform, or refactor).
- Testing and Validation: Rigorous testing ensures all systems function correctly in the new environment.
- Cutover Planning: Scheduling the final switch from VMware to AWS with minimal downtime.
Throughout this process, it’s crucial to maintain clear communication with all stakeholders and have a rollback plan in case of unforeseen issues.
Post-Migration optimization
The migration project doesn’t end once your workloads are running on AWS. Continuous optimization is necessary to maximize the benefits of cloud migration. These are some of the monitoring, performance tuning, and security management tools, which are essential for maintaining an efficient and resilient environment.
- Performance Monitoring: Utilize AWS CloudWatch to track resource utilization and application performance, adjusting as needed.
- Cost Optimization: Leverage AWS Cost Explorer and AWS Trusted Advisor to identify cost-saving opportunities, such as right-sizing instances or using reserved instances.
- Security Enhancement: Regularly review and update security measures using AWS security best practices and tools like AWS GuardDuty for threat detection.
- Continuous Improvement: Stay informed about new AWS services and features that could further enhance your infrastructure.
