The Ultimate Guide to Cloud Migration Strategies: 7 Rs Explained

These days, more and more businesses are moving their computer systems to the cloud. Instead of keeping all their programs and data on their own computers, they're choosing to use services over the internet. But moving to the cloud isn't always simple - there are different ways to do it based on what your business needs. Let's look at the seven main ways you can move to the cloud, known as the "7 Rs."

1. Lift and Shift (Rehost)

This is like picking up your furniture from one house and putting it in another without changing anything. You take your programs exactly as they are and move them to the cloud. It's quick and simple, but you might miss out on some cloud benefits.

When to use it:

• You need to move quickly

• You want to keep things simple

• You're not ready for big changes

2. Rebuild Better (Refactor)

This is like renovating your house completely. You take your programs apart and rebuild them to work better in the cloud. It takes more time and money, but your programs will run better afterward.

When to use it:

• You want your programs to run faster

• You're ready to invest time and money

• You want to use all the cloud's special features

3. Small Changes (Replatform)

This is like making minor home improvements. You keep most of your programs the same but make small changes to help them work better in the cloud. It's a middle ground between lifting-and-shifting and rebuilding.

When to use it:

• You want some improvements but can't rebuild everything

• You have limited time and money

• You want better performance with fewer changes

4. Buy New (Repurchase)

Instead of moving your old programs, you switch to new cloud-based ones. It's like selling your old furniture and buying new pieces that fit your new house better.

When to use it:

• Your current programs are outdated

• You want to use ready-made cloud services

• You don't want to maintain your own programs

5. Get Rid Of (Retire)

Sometimes you discover programs you don't need anymore. This is like throwing out old stuff when you move houses - it saves money and makes things simpler.

When to use it:

• You find programs nobody uses

• You want to save money

• You want to simplify your systems

6. Keep As Is (Retain)

Some things are better left where they are. This means keeping certain programs on your own computers instead of moving them to the cloud

When to use it:

• Some programs must stay for legal reasons

• Moving right now isn't practical

• The program works fine where it is

7. Move Between Clouds (Relocate)

This means moving from one cloud service to another, like moving between apartment buildings to get a better deal or better features.

When to use it:

• You find better prices elsewhere

• Another cloud service has features you need

• You want to avoid depending too much on one provider

Choosing the Right Strategy

Picking the best migration strategy depends on:

• Application Dependencies: Map out relationships and compatibility.

• Business Goals: Align with priorities like scalability or cost reduction.

• Resources: Consider time, expertise, and budget.

• Compliance: Ensure adherence to regulations.

• Cost Analysis: Gauge ROI to make informed choices.

Cloud Migration Best Practices

• Assess Thoroughly: Audit your IT environment.

• Start Small: Begin with non-critical workloads

• Automate Processes: Leverage migration tools.

• Upskill Teams: Train staff on cloud technologies.

• UMonitor Performance: Continuously optimize post-migration.
