Can you name the main tools for automatic service discovery in a distributed system?

Main tools for automatic service discovery in distributed systems:

• Consul — a service by HashiCorp that provides registration, discovery, and configuration of services with support for health checks.
• etcd — a distributed key-value store often used to store information about services and their status.
• Zookeeper — a centralized service for managing configuration and synchronization, used for service discovery.
• Eureka — a service by Netflix, popular in the Spring Cloud ecosystem for registering and discovering microservices.
• Kubernetes DNS and CoreDNS — built-in service discovery mechanisms in Kubernetes clusters.

These tools help automatically find addresses and statuses of services, simplifying scaling and management of distributed applications.
