# Nacos: Dynamic *Na*ming and *Co*nfiguration *S*ervice [](https://gitter.im/alibaba/nacos?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge) [](https://www.apache.org/licenses/LICENSE-2.0.html) [](https://travis-ci.org/alibaba/nacos) ------- ## What does it do Nacos (official site: [nacos.io](https://nacos.io)) is an easy-to-use platform designed for dynamic service discovery and configuration and service management. It helps you to build cloud native applications and microservices platform easily. Service is a first-class citizen in Nacos. Nacos supports almost all type of services，for example，[Dubbo/gRPC service](https://nacos.io/en-us/docs/use-nacos-with-dubbo.html), [Spring Cloud RESTFul service](https://nacos.io/en-us/docs/use-nacos-with-springcloud.html) or [Kubernetes service](https://nacos.io/en-us/docs/use-nacos-with-kubernetes.html). Nacos provides four major functions. * **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 health checks of services to prevent sending requests to unhealthy hosts or service instances. * **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, which makes configuration changes more efficient and agile. * **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. ## Quick Start It is super easy to get started with your first project. #### Step 1: Download the binary package You can download the package from the [latest stable release](https://github.com/alibaba/nacos/releases).
