When we talk about service mesh, consul is one of the open-source tools which is widely used as a service discovery for multiple ephemeral or non-ephemeral resources. There are multiple consuls [service mesh] alternatives which are used as a service discovery but we won’t be discussing service discovery & alternative comparisons here.

If we talk about consul, it is not only used as a service mesh but also provides multiple options and features other than a service mesh. Yes, you heard it right, this lad can do lots of things that we didn’t know or haven’t explored yet.

Let’s talk about some of the options or features provided by the consul and further, we will discuss some of the aspects and impact of things provided by the consul.

What is a Service Mesh?

A service mesh helps in monitoring and controlling how different parts of an application share data with each other.

This helps in identifying issues and making it easier to optimize communication and avoid downtime as an app grows. A service mesh ensures that the communication among the services within the containerized infrastructure is fast, reliable, and secure.
