Eureka VS consul

I was setting up microservices based on Netflix Eureka and experimenting on top of spring-cloud and after weeks of research and development the question rose!

The closest thing I've found is Netflix's Eureka, though its very Java oriented and I found hard to use.

There's an open issue documenting this problem on Spring Cloud Netflix and Netflix Eureka.

if you want to get more knowledge of the services, eureka etc, you can debug it. but I will digest you use the library instead of the annotations: https://github.com/Netflix/eureka

Service discovery — Traditionally provided by platforms like Netflix Eureka or Consul.

With multiple services running, it’s hard to discover where they’re located. The dependencies between multiple services are not always easily found, and new services may be deployed with a new dependency on an older service. Those services can be deployed anywhere in the infrastructure, so what you need is a Service Discovery service. There are plenty available, such as Netflix Eureka or HashiCorp Consul.

When a backend starts or stops, something needs to update, whether it’s Consul, kube-proxy, ELB, or otherwise. To stop a worker without incurring failures, you need to prevent the load balancer from sending new requests and then finishing existing ones.

Consul - To set up secure network communication via mTLS, service location and certificate issuance

Hashicorp Consul

The JHipster scaffolded sample application has a gateway application and two microservices. It uses Consul for service discovery and centralized configuration.

Service Discovery: Microservices need to discover and communicate with each other dynamically. Service discovery tools like etcd, Consul, or Kubernetes built-in service discovery mechanisms help locate and connect to microservices running on different nodes within the infrastructure.

After some research and testing, I landed on using Consul and Fabio as the demo infrastructure. Of course, there is a myriad of other options to accomplish this task, but because of the low configuration and ease of use, I was impressed with this pairing. Both projects are mature and well-supported, and very flexible--just because you can run them with low configuration, doesn't mean you have to. I wanted to keep this demo constrained, but the exercise did get me excited about exploring things further: circuit breakers, traffic splitting, and more complex service meshes.

The goal is to be able to use Consul SD configurations to allow for retrieving scrape targets from consul. Is this possible? Can anyone provide an example? Thank you!!

The Consul collector is production ready! Consul by HashiCorp is a powerful and complex identity-based networking solution, which is not trivial to monitor. We were lucky to have the assistance of HashiCorp itself in this endeavor, which resulted in a monitoring solution of exceptional quality. Look for common blog posts and announcements in the coming weeks!
