Getting Started with AWS Migration Evaluator

Prerequisites

Before using AWS Migration Evaluator, ensure that you meet the following requirements:

• An AWS account with appropriate permissions to create and manage AWS Migration Evaluator resources.
• Access to your on-premises infrastructure for data collection (this may require the installation of the AWS Migration Evaluator agent).
• A clear understanding of your migration goals and objectives.

Setting Up AWS Migration Evaluator

 Accessing the AWS Migration Evaluator

1. Log in to the AWS Management Console.
2. Navigate to the AWS Migration Evaluator service from the AWS Management Console.

Installing the AWS Migration Evaluator Agent

1. Download the Agent:

   • AWS Migration Evaluator requires a lightweight agent to collect data from your on-premises environment.
   • Download the appropriate agent for your operating system from the AWS Migration Evaluator console.

2. Install the Agent:

   • Follow the installation instructions provided in the AWS Migration Evaluator documentation.
   • Ensure that the agent is installed on the servers you wish to assess.

3. Configure Network Settings:

   • Ensure that the agent can communicate with AWS services over the Internet. This may involve configuring firewalls or proxy settings.

 Data Collection

• Data Collection Period: The agent collects utilization data over a defined period (usually around 14 days). This data includes CPU usage, memory utilization, disk I/O, and network traffic.
• Data Upload: After the collection period, the agent automatically uploads the collected data to the AWS Migration Evaluator.

Using AWS Migration Evaluator

Creating a Migration Project

1. Define Project Scope: In the AWS Migration Evaluator console, create a new migration project by defining the scope of the assessment, including which workloads to evaluate.
2. Select Agent Data: Choose the data collected by the agent to analyze specific workloads or applications.
3. Configure Project Settings: Set preferences for cost estimation, such as desired AWS regions and service types.

Analyzing Workloads

1. View Workload Insights: After the data is processed, you can view detailed insights on each workload, including:

   • Resource utilization metrics.
   • Application dependencies.
   • Potential AWS services for migration.

2. Cost Analysis: Utilize the cost estimation feature to generate reports that compare on-premises costs with potential AWS costs. This report helps stakeholders understand the financial implications of migration.

3. Performance Optimization Recommendations: Based on the analysis, the tool provides recommendations for optimizing workload performance on AWS, such as instance types and storage options.

Generating Reports

1. Comprehensive Reporting: AWS Migration Evaluator offers various reports summarizing findings, including workload assessments, cost estimates, and performance recommendations.
2. Export Reports: You can export reports in different formats (PDF, CSV) for sharing with stakeholders or for documentation purposes.

Best Practices for Using AWS Migration Evaluator

Define Clear Objectives

Before starting with AWS Migration Evaluator, clearly define your migration objectives and success criteria. This will guide the assessment and help you measure success post-migration.

Use a Sufficient Data Collection Period

Allow enough time for data collection to ensure accuracy. A collection period of at least 14 days is recommended to capture variations in resource usage.

 Analyze Workload Dependencies

Pay attention to workload dependencies identified during the analysis phase. Understanding these dependencies is crucial for planning the migration sequence and minimizing downtime.

Involve Stakeholders

Engage relevant stakeholders throughout the evaluation and planning process. This includes IT teams, finance, and business unit leaders, ensuring alignment on migration objectives and strategies.

Regularly Review and Update Reports

As your on-premises environment changes (e.g., new applications or infrastructure), regularly revisit AWS Migration Evaluator to update assessments and refine migration plans.

Case Studies and Real-world Applications

Financial Services Company

A financial services company used AWS Migration Evaluator to assess its data center environment, enabling it to identify underutilized resources and opportunities for consolidation. By moving to AWS, they estimated a 30% reduction in operational costs and improved application performance by selecting optimized instance types.

E-Commerce Business

An e-commerce business leveraged AWS Migration Evaluator to analyze its seasonal traffic patterns. By assessing workload dependencies and utilization, the company planned a phased migration that minimized downtime during peak shopping periods. Post-migration, they experienced enhanced scalability and flexibility in handling traffic spikes.

Healthcare Provider

A healthcare provider utilized AWS Migration Evaluator to understand its legacy systems' performance and dependencies. The tool helped identify compliance requirements for data handling in the cloud, ensuring that the migration plan adhered to industry regulations. This led to a successful migration that improved patient data accessibility while maintaining compliance.

Troubleshooting Common Issues

Data Collection Errors

Problem: The agent fails to collect data or report errors.

Solutions:

• Check Agent Status: Ensure the AWS Migration Evaluator agent is running and configured correctly.
• Network Configuration: Verify network settings to ensure the agent can communicate with AWS services.
• Firewall Rules: Confirm that necessary ports are open for data transmission.

 Incomplete or Inaccurate Data

Problem: Collected data appears incomplete or does not reflect actual usage.

Solutions:

• Data Collection Period: Extend the data collection period to capture variations in workload utilization.
• Multiple Agents: Deploy multiple agents across different servers to capture a more comprehensive view of the environment.
