Alibaba is back with yet another project. Nacos is a dynamic naming and configuration service that provides a service-centered modern application architecture with a microservices or cloud-native approach. Let’s take a look.

The Alibaba team never rests!

Today we take a look at a new Alibaba project named Nacos.

Nacos is a dynamic naming and configuration service and it provides a set of features that aim to help you to realize dynamic service discovery, service configuration, service metadata, and traffic management.

According to its GitHub repo, “service is a first-class citizen in Nacos!” So, as you can imagine, support for multiple types of services is central to this tool.

With no further ado, let’s have a look at Nacos’ main characteristics and functions.

What can you do with Nacos?

As mentioned earlier, service support is a central concept in Nacos and it supports almost any type of service including:

  • Kubernetes Service
  • gRPC & Dubbo RPC Service
  • Spring Cloud RESTful Service

To make it a bit more clear, the following figure represents Nacos’ basic architecture and concepts.

But what exactly can you do with Nacos?

Among others, Nacos offers four key features.

  • Service discovery and service health check: Offers support for DNS-based as wells as RPC-based (Dubbo/gRPC) service discovery.
  • Dynamic configuration management: Enables you to manage the configuration of all applications and services in a centralized, externalized as well as dynamic manner across multiple environments.
  • Dynamic DNS service: By supporting weighted routing, this function makes it easier for you to implement mid-tier load balancing, flexible routing policies, traffic control, and simple DNS resolution services in your production environment within your data center.
  • Service governance and metadata management: You can manage all of your services and metadata as a microservices platform builder.

Head over to the official documentation or Nacos’ GitHub repo to find out more about these features.
