In this lesson, we explore AWS Migration Hub—a powerful service from AWS designed to assist enterprises and organizations in planning and managing application and workload migrations to the AWS cloud. With a centralized view, Migration Hub enables you to monitor and track migration progress across multiple AWS and partner solutions efficiently.

​
Discovery Phase

Before initiating your cloud migration, gathering detailed information about your on-premises environment is crucial. AWS Migration Hub facilitates this through a discovery process that collects extensive data about your servers and services. You can choose from two discovery methods:
  • Agent-based discovery: Install an agent on your servers to retrieve detailed metrics and insights.
  • Agentless discovery: Collect essential data without installing any software on your servers.
This process compiles information such as CPU utilization, memory usage, and network traffic, providing you with the necessary details to plan your migration accurately.

For optimal accuracy, ensure that the chosen discovery method aligns with your current infrastructure and privacy requirements.

​
Assessment Phase

After completing the discovery phase, AWS Migration Hub transitions into the assessment phase. Here, the service analyzes the gathered data to recommend ideal target EC2 instance sizes and provide cost estimates. This phase addresses important questions such as:
  • Am I selecting the optimal EC2 instance size for my workloads?
  • Will this migration be cost-effective based on projected resource usage?
These assessments simplify the planning process by offering actionable insights tailored to your specific environment.

Migration Process

Upon finalizing instance sizing and evaluating costs, you can move forward with the migration process. AWS Migration Hub serves as the central management console, integrating seamlessly with several AWS migration services, including:
  • AWS Application Migration Service
  • AWS Database Migration Service
…as well as various partner migration tools. During this stage, Migration Hub continuously provides updates on your migration progress until the entire process is successfully completed.
