While Consul is a tempting option since it’s extremely lightweight and streamlined, a couple of drawbacks are the fact that it enforces authorization and identity only to Layer 4 though it does plan on adding Layer 7 features in the future. Although there is no single system that provides all the features of Consul, there are other options available to solve some of these problems. If resources are your priority, however, Consul is the way to go, or at least until someone comes up with a “flyweight” mesh that runs on nothing and uses no resources. That paves the way for authentication, encryption, and stronger communication. Consul Connect is another “built-in” feature and uses Transport Layer Security (TLS) to provides service-to-service encryption, as well as authorization. It’s common knowledge that the more components or “moving parts” your service mesh are made up of, the longer the processing time incurred and the lower the overall performance. Battle of the Kubernetes service meshes: Istio vs. Consul The arrival of service meshes has made the job of facilitating (and regulating) communications between microservices a lot easier.

Consul vs. Istio Consul began as a service discovery tool, but its founders have rebranded it as a complete service mesh. Similar to how an SDN functions, Istio is split into a data plane and control plane where the data plane is made up of proxy sidecars and the control plane is further split into three components. The data plane for Consul is pluggable. Yet many other options exist, including Consul Connect, Kuma, AWS App Mesh, and OpenShift. I think the right one will be based on users objectives and needs, as not everyone needs the 47 new CRDs that come with Istio. Fortunately, Consul Connect uses Envoy as its proxy. Whereas Kubernetes does an important job of abstracting infrastructure so that there’s uniformity in deployment, uniformity throughout runtime nonetheless left rather a lot to be desired.
