AWS App Mesh
AWS App Mesh operates as a service mesh for monitoring and controlling microservices. It sits in your networking layer to manage traffic between services, giving you visibility into how they communicate. You pay as you go for this infrastructure, which fits teams already deep in the AWS ecosystem who need granular control over service-to-service interactions without managing the underlying mesh infrastructure themselves.
This setup suits organizations comfortable with AWS-native tools, but there is a clear trade-off. There is no free tier available, meaning every hour of operation costs money. If you are running small-scale experiments or just starting out, the lack of a free allowance makes it a less attractive option compared to other solutions that offer a zero-cost entry point for testing.
