7. Overview

• Nacos /nɑ:kəʊs/ is the acronym for Dynamic Naming and Configuration Service, a dynamic service discovery, configuration management and service management platform that is easier to build cloud-native applications.

• Nacos is dedicated to helping you discover, configure and manage microservices. Nacos provides a set of easy-to-use feature sets to help you quickly realize dynamic service discovery, service configuration, service metadata, and traffic management.

• Nacos helps you build, deliver and manage microservice platforms more agilely and easily. Nacos is a service infrastructure for building a "service"-centric modern application architecture (such as microservice paradigm, cloud native paradigm).

• Nacos provides real-time health checks on services, preventing requests from being sent to unhealthy hosts or service instances. Nacos supports transport layer (PING or TCP) and application layer (such as HTTP, MySQL, user-defined) health checks. For the health check of services in complex cloud environments and network topology environments (such as VPC, edge network, etc.), Nacos provides two health check modes: agent reporting mode and server active detection. Nacos also provides a unified health check dashboard to help you manage service availability and traffic based on health status.

8. Ecology

  Use Nacos to simplify service discovery, configuration management, service governance and management solutions, making it easier to discover, manage, share and combine microservices.
