Netflix Hystrix Circuit Breaker In one of my previous blogs, I have already discussed the Circuit breaker pattern and its usage, Today, we will see how can we implement it in our application using Spring Cloud Netflix Hystrix . In this document, I’ll walk you through the process of applying circuit breakers to potentially-failing method calls using the Netflix Hystrix fault tolerance library. Hystrix is watching methods for failing calls to related services. If there is such a failure, it will open the circuit and forward the call to a fallback method. To understand it in a better way, I’ll take the same problem statement that I have already discussed in my previous blog i.e. E-commerce Portal.  I am assuming you must be aware of Spring boot framework as this implementation is completely based on it. As per problem statement, we need two applications i.e. Product Service & Price Service but in this tutorial, I’ll talk about just Product Service as Price Service ...

Circuit Breaker and Microservices Architecture  In this article, I’ll talk about the Circuit Breaker pattern which is widely used in Microservices but before jumping to Circuit breaker design pattern or microservices. Let’s first understand the requirement so that you should know where we can use it in our application and Of Couse, How 😊 Let’s understand it with the real scenario as It’s already June month and we know there are so many online summer sales is going to start where they will offer you a various type of deals on their products. And as we know most of the online portal has upgraded their application arch from Monolithic design to Microservices like Amazon, Flipkart, Snapdeal and so on and with that their each service will be running as an independent micro-services in the cloud like Authentication Service using which a user can be logged in to the application, Product Detail Service, Billing Service, Price Service, Card Services, etc. Now just imagine the sce...
