Vendors and their services:

1. Netflix
2. Spring Cloud
3. Apache (Zookeeper License)
4. Hashicorp

Vendor wise services:

2. Netflix Ribbon – Dynamic Routing and load balancer
3. Netflix Zuul -Edge/Proxy/Gateway server
4. Netflix feign – REST Client

Use-case wise services –

Gateway – One is the Eureka and other is Spring cloud Gateway

Configuration management – for distributed configuration management etcd , vault /consul ,

Spring cloud :

What is Eureka and how does service discovery work?

Sample Answer:

Eureka is Spring Cloud’s service discovery component. Each microservice registers itself with the Eureka server on startup and periodically sends heartbeats. Clients (or the API Gateway) query the Eureka server to discover other service instances. This enables load-balanced service-to-service communication without hardcoding hostnames.
