Aggregator Design Pattern Tutorial with Examples for Software Programmers & Beginners

In this video we will learn about Aggregator design pattern. This is the second design principle in Integration design patterns category for microservices. In microservices the Aggregator Design Pattern is a service that receives a request, then makes requests of multiple services, combines the results and responds to the initiating request. The Service aggregator design pattern is receives a request from the client or API Gateways, and then dispatches requests of multiple internal backend microservices, and then combines the results and responds back to the initiating request in 1 response structure. In Microservices Architecture, we split a large, complex application into small, autonomous, independently deployable services. Therefore, it’s necessary to think about how to collaborate the data returned by each service. Aggregator Microservice collects pieces of data from various microservices and returns an aggregate for processing. By Service Aggregator Pattern implementation, we can reduces chattiness and communication overhead between the client and microservices. ** Usage of this Design Pattern ** 1. Use this pattern when requires low transaction rate/low demand/low expected increased rate of demand activities. 2. Use this pattern when project requires more than one team to implement it in parallel. ** Advantages of this Design Pattern ** 1. This pattern is easy to understand and implement. 2. This pattern provides single access point for microservices. 3. This pattern reduces chattiness and communication overhead between the client and microservices. ** Chapter Timestamps ** 0:00 Welcome to Aggregator design pattern 1:01 Agenda of tutorial 2:07 Introduction of Aggregator design pattern 5:40 Real world examples of Aggregator design pattern 6:02 Usage of Aggregator design pattern 7:00 Advantages of Aggregator design pattern 8:04 Summary of Aggregator design pattern 8:37 Next video on Aggregator design pattern #microservicedesignpatterns #aggregator #aggregatorpattern ** CHECK OUT OUR OTHER VIDEOS ** 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 ** Spring Boot Complete Tutorial    • Spring Boot Tutor...   Docker Containers Complete Tutorial    • Cloud & Container...   Microservice Architecture and Microservice Design Patterns Tutorial    • Microservice Arch...   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.
