Nacos: Dynamic Naming and Configuration Service
What does it do
Nacos (official site: 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.
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.
It is super easy to get started with your first project.
Deploying Nacos on cloud
You can deploy Nacos on cloud, which is the easiest and most convenient way to start Nacos.
