Website Analysis and Migration Planning

Examine Your Current Website Setup

Before moving to AWS, take a close look at your existing website infrastructure. Create a detailed inventory that includes your web server configuration, database systems, storage solutions, traffic patterns, and any third-party integrations. This information is critical for shaping your migration plan and timeline.

Build a Migration Timeline

Start your migration timeline by assessing your current infrastructure. The AWS Migration Acceleration Program (MAP) provides a structured framework to guide this process. The time it takes to migrate will vary depending on factors like the complexity of your setup, the amount of data, and your business needs.

Divide the migration into three key phases:

1. Assessment Phase
   Identify dependencies, evaluate risks, and conduct a cost analysis.
2. Planning Phase
   Set clear milestones, define success criteria, allocate resources, and prepare contingency plans.
3. Execution Phase
   Deploy the required AWS infrastructure, migrate your data, and thoroughly test the new environment to ensure everything works as intended.

Involve stakeholders from the beginning to ensure alignment and timely decisions. Once your timeline is in place, shift your focus to securing your data and systems.

Evaluate Security Requirements

After finalising your timeline, ensure your security measures align with UK GDPR standards. Use a security checklist to address data protection and compliance:

Data Protection Measures

• Ensure data remains within UK/EU borders.
• Apply encryption for both data in transit and at rest.
• Establish reliable backup and disaster recovery systems.

Compliance Documentation

• Review AWS's Data Processing Agreement.
• Document your organisation’s data handling practices.
• Create clear protocols for incident response.

Collaborating with an AWS Advanced Tier Consulting Partner can help you navigate the migration process while ensuring your strategy meets AWS best practices and complies with UK data protection laws.

Calculate AWS Costs

Use the AWS Pricing Calculator to estimate your monthly expenses based on your resource requirements.

• Cost-Saving Options
  • Reserved Instances can cut costs by up to 72% compared to standard on-demand pricing.
  • Savings Plans offer flexible pricing with similar discount potential.
  • Review your S3 usage to ensure you’re using the most economical Storage Classes for your access patterns.

"In an example provided by Aligned Technology Group, a small AWS deployment with little management oversight resulted in a 51% monthly savings by eliminating unused storage volumes and an old application server."

Website Migration Steps

Set Up Your AWS Account

To begin, you'll need to set up your AWS account:

1. Visit the AWS website and provide your email address and account name.
2. Enter your business details and agree to the AWS Customer Agreement.
3. Add a valid payment method.
4. Complete the phone verification process.
5. Choose an AWS Support plan that fits your needs.

For added security, take these steps:

• Enable multi-factor authentication (MFA) for the root account.
• Create an IAM administrator user for daily tasks instead of relying on root credentials.
• Set up IAM access to the Billing and Cost Management console under Account settings.

Note: While most AWS accounts are activated within minutes, it can take up to 24 hours for full activation.

Once your account is ready, you're set to begin migrating your website content.

Move Website Content

With your AWS account configured, use your documented configurations to start migrating your website content. AWS offers several tools designed to handle different types of migrations:

Choose the tool that best fits your migration needs to ensure a smooth transition.

Switch to AWS and Test

Before updating your DNS records, conduct thorough testing to ensure everything works as expected:

1. Initial Validation
   Update your local hosts file to point to the new EC2 instance. This allows you to test the website without affecting live traffic.
2. Performance Testing
   Check that all applications are functioning correctly on the new infrastructure. Use tools like SSH or Telnet to test connectivity and response times.
3. Database Verification
   For WordPress, update the configuration file to connect to the new database instance. For other applications, confirm that all database queries and connections are functioning properly.

Once testing confirms your website is stable, you can proceed to optimise your setup after migration.

After Migration Tasks

Once your website migration is complete, the focus shifts to ensuring strong performance, tight security, and efficient cost management.

Monitor AWS Performance

Use AWS CloudWatch to monitor your website's performance. Set up a dashboard to track key metrics like:
