A Practical Guide to AWS Cloud Migration for South African Businesses

Cloud migration is no longer optional for growing businesses. Here is a practical guide to migrating to AWS.

Why Migrate to AWS?

AWS offers scalable infrastructure, pay-as-you-go pricing, and a vast ecosystem of services. For South African businesses, the Cape Town region (af-south-1) provides low-latency access for local users.

Migration Strategies

There are several approaches to cloud migration. Lift-and-shift moves your existing applications as-is. Re-platforming makes minimal changes to take advantage of cloud features. Re-architecting redesigns applications to be cloud-native.

Step 1: Assessment

Start by assessing your current infrastructure. Inventory your applications, dependencies, and data. Identify which applications are good candidates for migration and which might need re-architecting.

Step 2: Planning

Create a migration plan that prioritises low-risk, high-value migrations first. Plan for data transfer, testing, and cutover. Consider using AWS Migration Hub to track your progress.

Step 3: Execution

Execute migrations in waves. Start with a pilot migration to validate your process. Use AWS Database Migration Service for database migrations and Application Migration Service for servers.

Step 4: Optimisation

After migration, optimise your AWS environment. Right-size instances, set up auto-scaling, and implement cost monitoring. Many businesses save 30-50% after optimisation.
