What's the Best Way to Migrate to the Cloud?

Not sure what migration strategy is right for you? This tutorial will help you understand the best way to migrate to the cloud.

Going cloud-native

So, you know the different options for cloud migration, but how do you know which is best for you? It’s important to understand how you will derive value from the cloud, and take it from there. 

In an ideal world, you’d re-build everything to go cloud-native. But this can be time-consuming and potentially risky.  Think carefully about how, where and when you will leverage cloud capabilities. Be pragmatic as well as strategic. 

Lift and shift migration

Many organisations go for the speed of ‘lift and shift. This is a good option when you need to move fast, for instance if there’s a datacentre exit deadline looming.   

However, it doesn’t unlock advantages such as scalabilty, flexibility, and cost-savings. In fact, simply replicating your current infrastructure in the cloud could cost more and make existing problems worse. 

Modernisation is key

To maximise cloud benefits, you need to evolve your infrastructure, modernising systems and improving operability. This can be done during the migration. Or it can happen after you’ve completed a lift and shift.   

Modernisation is key. The main question is whether it’s best to migrate then modernise, or modernise as you migrate. And the answer might vary across different parts of the estate. 

Improving your cloud performance

Classic DevOps approaches such as containerisation, platform-as-a-service and infrastructure as code can deliver excellent outcomes. They drive tangible improvements in the cost, reliability and operability of IT, without a full rewrite.   

These infrastructure-level improvements make a big difference to performance in the cloud. What’s more, they work with the existing codebase, so you don’t need largescale refactoring, or new languages and frameworks.  

There’s no single best way to get to the cloud. The trick is to determine which combination of approaches best suits your needs and your application portfolio.
