AWS Migration — The Architect’s Handbook

Cloud is the way to go. And AWS is the most popular cloud service. So it is natural that everyone wants to migrate to AWS. But often that is not as simple as it sounds. The bigger and older your legacy system, the harder it is to migrate.

Amazon suggests a step by step process for performing such a migration. Here are my two cents on that.

Why Migrate?

The benefits of being on the cloud have been repeatedly advertised over and over in the technical community. I don’t want to repeat them all over again. But here, let’s look at some reasons why people are not eager to migrate.

Do we really need to migrate?

This question has held back many of us. Billions of dollars are wasted every year because people are not able to conclude on this. The answer is, Yes. Even the pettiest application deserves a place in the cloud. May be you are just a simple desktop application that is doing well within the windows. Even then, connecting it to the AWS will add a lot of value that you can never imagine without a cloud.

Cloud Locking

That’s another doubt bubbling in our mind. Well, to think of it, if we are not on the cloud, today we are locked in the premise! And this locking is a lot more wasteful.
