Hey everyone 👋
If you're getting serious about moving to the cloud, especially with AWS, you'll eventually run into one big question:
How do I actually migrate to the cloud?
Not just spinning up new stuff — but actually moving apps, databases, and data from wherever they are today.
In this post, I’ll walk you through the AWS approach to cloud migration — including the strategy, the planning framework, and the services/tools AWS gives you to pull it all off.
Let me break it down the way I wish someone had explained it to me 👇
🗺️ Think of It Like Planning a City-Wide Move (With Everyone Involved)
Imagine your company as a small city.
You've got homes (apps), warehouses (databases), documents (files), and people with very different job titles.
When it’s time to move to a brand new digital neighborhood — AWS — you’ll need:
✅ A plan to align everyone (that’s AWS CAF)
✅ Strategies for moving each "building" (the 7 Rs)
✅ Tools to get it all done safely and efficiently (AWS migration services)
🧭 Step 1: AWS CAF — The Cloud Adoption Framework
CAF = your migration game plan, built to include every team — from HR to Ops to Security.
🧠 It breaks your company into 6 perspectives:
- Business (goals + financial ROI)
- People (training and staffing)
- Governance (tracking and risk)
- Platform (the actual cloud build)
- Security (compliance and data safety)
- Operations (day-to-day workflows)
🧩 Think of this like assigning roles for the big move. Everyone gets a checklist. No one is left behind.
🚚 Step 2: Choose the Right Migration Strategy (The 7 Rs)
Not every app should be treated the same. That’s why AWS uses 7 migration strategies — known as the 7 Rs:
| 📦 Strategy | 💡 Description | 🏠 Analogy |
|---|---|---|
| Rehost | Lift and shift as-is | Move your furniture into a new house, no changes |
| Relocate | Move whole environment | Move the entire building as-is |
| Replatform | Minor cloud tweaks | Swap the sofa, keep everything else |
| Refactor | Rewrite the app | Tear down the house and build new |
| Repurchase | Replace with SaaS | Cancel your lease and rent a new place |
| Retain | Leave it as-is for now | Keep a few things in storage |
| Retire | Shut it down | Sell or donate what you no longer need |
Most orgs use a mix of strategies depending on the app.
Start with the low-hanging fruit (like Rehost or Replatform), then tackle the complex ones later.
🧰 Step 3: Use the Right AWS Tools to Move Your Stuff
AWS gives you migration tools for apps, databases, and data. Here's the cheat sheet:
✅ Application Migration
- AWS Application Migration Service (MGN) Automatically replicates and moves apps from on-prem to AWS. No need to rebuild manually.
✅ Database Migration
- AWS Database Migration Service (DMS) Moves your DBs with minimal downtime Works for MySQL, Oracle, PostgreSQL, and more
- AWS Schema Conversion Tool (SCT) Converts DB structure when switching engines (e.g., Oracle → Aurora)
✅ Data Transfer (Files & Datasets)
- AWS DataSync → Large online transfers (S3, EFS)
- AWS Transfer Family → Secure FTP, SFTP transfers
- AWS Direct Connect → Private, high-speed dedicated network
- AWS Snowball Edge → Ship physical storage when internet won’t cut it
🧠 Why This Matters
Without a clear plan, migration can be:
❌ Expensive
❌ Slow
❌ Risky
❌ Frustrating for teams
But with AWS CAF, the 7 Rs, and the right services, you’re more likely to:
✅ Migrate faster
✅ Save money
✅ Modernize your stack
✅ Get early wins
🧩 Final Thoughts
Moving to the cloud isn't just a technical task — it's a team-wide transformation.
Luckily, AWS gives you the blueprint (CAF), the roadmap (7 Rs), and the moving truck (DMS, MGN, Snowball, etc.)
If you’re planning your migration or already mid-move, I hope this gave you a clearer picture of what’s possible — and how to do it without chaos.
