Learning Cloud Migration · concepts → clouds → practice

Move from the data center to the cloud — without the fear.

A self-paced, beginner-friendly path through IT migration: what it really means to move applications and data from your own server room to the cloud, the 7 R’s for deciding how to move each thing, the migration lifecycle, modernization, the patterns the pros reuse, and how data and cost actually behave — then the concrete specifics for the three clouds people move to: AWS, Microsoft Azure, and Google Cloud. No prior experience assumed.

☺ Like you’re 10

Imagine your family runs everything out of a creaky old house you have to fix yourselves — when the heater breaks at midnight, that’s your problem. The cloud is like moving into a giant apartment building where you rent exactly the rooms you need and the landlord fixes the pipes. This whole course is a friendly map for making that move: what to pack, what to throw away, how to carry the heavy boxes (your data) safely, and how not to drop anything on the way.

⚠ Independent & unofficial

Learning Cloud Migration is an independent, third-party educational resource. It is not affiliated with, endorsed by, or an official product of Amazon/AWS, Microsoft/Azure, or Google/Google Cloud. All product and service names are trademarks of their respective owners, used here only to describe what this course helps you learn. Tools, pricing, and limits change constantly — always verify current details in each provider’s official documentation.

How the course is built

☺ Like you’re 10: First you learn the moving basics that are true no matter which new building you pick. Then you get a guided tour of each of the three big “apartment buildings” in the sky. Then there are tools to help you practice and remember.

The course has four parts. Migration Foundations teaches the provider-neutral ideas — they’re true whether you move to AWS, Azure, or Google Cloud, so nothing you learn is wasted. Migration Directions widens the map beyond the classic move: cloud-to-cloud, hybrid, multi-cloud, and repatriation. The Cloud Tracks then show how each of the big three actually does a migration: their framework, their tools, and their gotchas. And Practice & Reference gives you case studies, a searchable glossary, flashcards, and a printable checklist.

Migration Foundations

The universal ideas: what & why we move, the 7 R’s, the migration lifecycle & frameworks, data migration, modernization, architecture patterns, anti-patterns, best practices, and security/cost/resilience. Start the foundations →

Cloud · the big three

Cloud Tracks

The same move, done three ways: AWS (Migration Acceleration Program, MGN, DMS), Azure (Cloud Adoption Framework, Azure Migrate), and Google Cloud (Migration Center, Migrate to Virtual Machines).

Directions

Cloud-to-Cloud & beyond

Not every move starts on-prem: switching providers, running hybrid and multi-cloud, and moving workloads back (repatriation). Explore the directions →

Cement it: real case studies, a searchable glossary, flashcards, the tools landscape, and a pre-move checklist.

Meet the Migration Academy

☺ Like you’re 10: To make the big ideas stick, this course is taught by a team of animal friends. Each one is an expert at one moving job — so the moment the elephant shows up, you know it’s time to talk about carrying the heavy boxes of data safely.

Every big idea has a recurring character who is that idea — 🦉 Professor Owl draws the map, 🐼 Master Panda keeps it calm and slow, 🦊 Foxy asks the question you’re thinking, 🐿️ Nutty takes inventory before you pack, 🦫 Benny the Beaver does the actual move and build, 🐘 Ellie the Elephant guards your data, 🦋 Mira the Butterfly transforms old apps into new ones, and 🐢 Timmy the Turtle double-checks everything — while 👺 Gizmo the Gremlin tries to tempt you into shortcuts. Watch for the “Your hosts for this topic” strip and the little 🎬 At the Migration Academy scenes in each lesson.

The one mental model that makes it all click

☺ Like you’re 10: For every single thing you own, you get to choose: keep it, toss it, move it as-is, tweak it a bit, or rebuild it brand-new. You don’t make one choice for everything — you choose per item.

Before any tool or cloud, internalize this: a migration is not one decision — it’s a decision per application. Every app you own gets sorted into one of the 7 R’s — Retire, Retain, Rehost, Relocate, Repurchase, Replatform, or Refactor — sliding along the spectrum above from “change nothing” to “rebuild it cloud-native.” Get that sorting right and the rest of the move is mostly execution.

Hold that idea. Most of this course is just filling in the spectrum — how to assess each app, pick its R, and move it safely, one wave at a time.

What’s inside

☺ Like you’re 10: The lessons are stacked like levels in a video game — each one uses what you learned in the level before, so you keep getting stronger.

01 · Start here

What & Why We Move

The big picture: what IT migration is, why organizations move, the directions (on-prem → cloud, cloud → cloud, hybrid), and IaaS/PaaS/SaaS.

02 · Foundations

The 7 R’s

The seven strategies for moving each app — Retire, Retain, Rehost, Relocate, Repurchase, Replatform, Refactor — and how to choose.

03 · Foundations

The Journey

The full lifecycle: assess, mobilize, migrate & modernize, operate — plus discovery, dependency mapping, TCO, landing zones, waves, and cutover.

04 · Foundations

Wave Planning

The heart of a safe move: grouping apps into waves, sequencing them pilot-first, sizing each batch, and running every wave with a runbook and a rollback.

05 · Foundations

Data Migration

The trickiest boxes: online vs offline, database migration, replication & CDC, and why data gravity and egress fees make data the hard part.

06 · Foundations

Modernization

Not just moving, but leveling up: containers, microservices, serverless, managed services, IaC, and when to modernize vs. just migrate.

07 · Foundations

Architecture Patterns

The proven recipes: strangler fig, anti-corruption layer, blue-green & canary cutovers, parallel run, and hybrid connectivity.

08 · Foundations

Anti-Patterns

Gizmo’s traps: big-bang moves, lift-and-shift-everything, moving junk, no rollback, bill shock, the distributed monolith — and the fix for each.

09 · Foundations

Best Practices

The handbook: assess first, wave planning, automation & IaC, the Well-Architected pillars, testing, rollback, and change management.

⌁ A note on dates

Cloud tool names, framework phases, and pricing move constantly. This course reflects the landscape in 2026; treat specific product names and numbers as “true at time of writing” and verify live details in each provider’s official docs. The concepts — the 7 R’s, the lifecycle, the patterns — are stable; the buttons and prices are not.
