So We Want to Do Some Migrations

Mike Amundsen describes the STAR (Stabilize, Transform, Add, and Repeat) method for safely and effectively migrating your existing IT infrastructure to a microservice platform. Watch a clip and read a transcript from the presentation. Watch a clip and read a transcript from the presentation at the GIDS Architecture Live 2020 series.

Let's talk about why we would ever do something as crazy as a migration, as dangerous as a migration for a running business, a business that's up and working already.

Well, it turns out all organizations, no matter what size they are, but especially as they mature, as they get larger, as they grow over time, have all sorts of technology all over the place. Technology that's five years old, technology that's 50 years old. I've got some organizations that have technology that's 70 years old. In some, sometimes they have technology that's just months old or they're still experimenting.

It's all over the map!

And eventually what we want to do is we want to harmonize pieces. We want to get pieces to start working together. So, we want to do some migrations.

Now, there've been lots of talk about why people migrate, and there's a great ResearchGate publication that talks about why people want to migrate. And what I find really interesting is some of the most common reasons for migration has to do with scalability and agility.

We want to make things more agile. We want to make things more flexible, but we also want to make them more scalable. There's lots of reasons for this. Now, extensibility and maintainability and reliability are up there too. We want all of those, but for the most part, most people talk about this notion of scaling and being agile.

In the full video, watch Simon talks about some production-ready, battle-tested strategies for evolving live systems with zero down-time. We will look at adding new functionality, refactoring live code, evolving database schemas, and a few of worst mistakes we made along the way.

If you are convinced that adding microservices to your IT organization’s offerings is a good idea but don't know how to get there or what it takes to move from monolithic releases to microservice releases and how can you do this in a way that doesn’t disrupt your current business, watch the full video of Mike's talk.
