Learn How to Control Consul Resources Using ACL

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.

Running Non-containerized Microservices

Whenever someone says orchestration for microservices, the first thing that usually comes to mind is Kubernetes. I believe that’s normal. I used to think the same but then I came across an interesting scenario that changed the way I used to think about microservice orchestration completely.

Usually, people think microservices mean containers, hence they build their application in a cloud-native approach so that it can easily run on any platform using the containerized approach. Well, I agree that containerization is a decent way of designing a cloud-native application especially when we integrate it with orchestrators like Kubernetes or OpenShift. It takes away a lot of overhead from us like:- scaling, failover, deployment, etc but it doesn’t imply that microservices can only be managed inside a containerized ecosystem. Microservice is an ideology or mindset for designing the application and containerization is a power-up that supports the ideology.
