Over the past few months, I’ve had the exciting opportunity to work on a cloud migration project. This adventure took me through the ins and outs of moving existing microservices from an on-premises environment to the cloud. And let me tell you, it’s been quite a journey!

One of the most interesting parts of this experience was getting hands-on with Istio service mesh. For those of you who might not be familiar, Istio is this awesome tool that simplifies communication between microservices, and it’s got some cool features we’ll explore together.

I’m writing this blog post mainly as a personal reference for future projects, but I’m really hoping it can help some of you out there as well. I plan to use AWS EKS and the Terraform EKS blueprint, which is a great way to quickly set up our infrastructure without getting bogged down in the details.

In the upcoming sections, I’ll walk you through the general building blocks and concepts of Istio, complete with examples to make things clearer. I’m aiming to keep things light and easy to understand, so whether you’re new to this or a seasoned pro, there should be something for everyone.

So, grab a cup of coffee, and let’s dive into the world of Istio and cloud migration!
