Service is a first-class citizen in Nacos. Nacos supports almost all type of services， ， Kubernetes service ](https://nacos.io/en-us/docs/use-nacos-with-kubernetes.html ).
2018-07-21 00:27:23 +08:00
2018-08-27 00:33:30 +08:00
Nacos provides four major functions.
2018-07-21 00:27:23 +08:00
* **Service Discovery and Service Health Check**
Nacos makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. Nacos also provides real-time healthchecks of services to prevent sending requests to unhealthy hosts or service instance.
* **Dynamic Configuration Management**
Dynamic Configuration Service allows you to manage configurations of all services in a centralized and dynamic manner across all environments. Nacos eliminates the need to redeploy applications and services when configurations are updated，
* **Dynamic DNS Service**
Nacos supports weighted routing, making it easier for you to implement mid-tier load balancing, flexible routing policies, flow control, and simple DNS resolution services in the production environment within your data center. It helps you to implement DNS-based service discovery easily and prevent applications from coupling to vendor-specific service discovery APIs.
* **Service and MetaData Management**
Nacos provides an easy-to-use service dashboard to help you manage your services metadata, configuration, kubernetes DNS, service health and metrics statistics.
