Chained Microservice Design Pattern with Examples for Software Developers

In this video we will learn about Chained Microservices design pattern. This is the 5th design principle in Integration design patterns category for microservices. Chained microservice design pattern the request from the client is received by Service A, which is then communicating with Service B, which in turn may be communicating with Service C. Chained microservice design pattern produce a single consolidated response to the request. A chain with a single microservice is called singleton chain. This may allow the chain to be expanded at a later point. Chained microservice Design Patterns produces a single output which is a combination of multiple chained outputs. The key part to remember is that the client is blocked until the complete chain of request/response, i.e. ServiceA calling ServiceB and ServiceB calling ServiceC, is completed. Another important aspect to understand here is to not make the chain too long. This is important because the synchronous nature of the chain will appear like a long wait at the client side, especially if it’s a web page that is waiting for the response to be shown. There are workarounds to this blocking request/response and are discussed in a subsequent design pattern. ** Usage of this Design Pattern ** 1. Use this pattern to achieve loose coupling where a request from the client is passed to a chained microservices. 2. Use this pattern when Multiple services have to handle a request. 3. Use this pattern When you want to issue a request to one of several services without specifying the receiver explicitly. ** Advantages of this Design Pattern ** 1. Chained microservices pattern avoid coupling the sender of a request to multiple services. 2. Chained microservices pattern simplifies the request and response for client to make call to only one service. 3. Chained microservices pattern support single responsibility principle to make sure each service is doing their job and request is passed to respective service in the chain. 4. It is easy to add new microservice in chain if requires in future. ** Chapter Timestamps ** 0:00 Welcome to Chained Microservices design pattern 0:59 Agenda of tutorial 1:50 Introduction of Chained Microservices design pattern 3:56 Real world examples of Chained Microservices design pattern 4:56 Usage of Chained Microservices design pattern 5:30 Advantages of Chained Microservices design pattern 6:16 Summary of Chained Microservices design pattern 6:57 Next video on Branch design pattern for microservices #microservices #chainedmicroservices #designpatterns ** CHECK OUT OUR OTHER VIDEOS ** Gateway Routing Design Pattern for Microservice    • Gateway Routing D...   Difference between Monolithic and Microservice Architecture    • Difference betwee...   Spring boot project setup:    • Spring boot Proje...   Spring Boot Microservice with postgres database Project:    • Spring Boot Micro...   Prepare Docker file, Container and Build Image:    • Docker Tutorial f...   Deploy Docker Image AWS Elastic Container Service:    • Deploy Springboot...   Solid Principle Tutorial    • Solid Principles ...   ** CHECK OUR PLAYLISTS ** Microservice Architecture and Microservice Design Patterns Tutorial    • Microservice Arch...   Spring Boot Complete Tutorial    • Spring Boot Tutor...   Docker Containers Complete Tutorial    • Cloud & Container...   Solid Principles Tutorial    • Solid Principles ...   Java Design Pattern Complete Tutorial with Examples    • Java Design Patte...   ** ABOUT OUR CHANNEL ** CodeOneDigest is a youtube channel that produces videos on programming languages, cloud and container technologies, Software design principles, Java frameworks in English and Hindi languages.
