“Microservices, in a nutshell, allows us to break our large system into a number of independent collaborating components.”
- Microservices is a variant of the service-oriented architecture (SOA) architectural style that structures an application as a collection of loosely coupled services.
- Each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API.
- Clients of a service use either Client-side discovery or Server-side discovery to determine the location of a service instance to which to send requests.
- Service instances are registered with the service registry on startup and deregistered on shutdown.
- API Gateway is a server that is the single-entry point into the system
- API gateway availability requires a load balancer that can provide flexibility to cope with rapid changes in microservices, such as versioning and dynamically shifting scale.
- A Hystrix system provides such data as a stream of JSON documents via HTTP. The Hystrix Dashboard can visualize the data in a web interface. The dashboard presents all Circuit Breakers along with the number of requests and their state (open/closed)
- Central configuration server provides configurations (properties) to each micro service connected
- With the Config Server you have a central place to manage external properties for applications across all environments.” Basically, a config server allows you to externally store variables your application will need to run in all environments, regardless of lifecycle, and update them in one, centralized place.
- Zipkin is very efficient tool for distributed tracing in microservices ecosystem.
- It helps gather timing data needed to troubleshoot latency problems in service architectures
