Overview: In the distributed systems, we enable loose coupling between systems by passing messages via a service bus / message queue. We had implemented that in one of the architectural pattern series here. Sometimes, when the message throughout is extremely high – that is number of the incoming messages per unit time is greater than […]
Overview: Let’s consider a distributed application in which requests are processed as and when they arrive. Let’s also consider that these requests are time-consuming tasks triggered by user actions on our application. As tasks will take time to process, it is better to get these requests queued, we could process them sequentially and notify the
Overview: In the reactive programming series with project reactor, I would like to show you the difference between Reactor Repeat vs Reactor Retry. If you are new to reactive programming or project reactor, take a look at this entire series to get a good idea on that. Need For Reactor Repeat & Retry: As we
Overview: In this tutorial, I would like to demonstrate the use of Kubernetes Adapter Pattern with a simple example. Kubernetes Adapter Pattern: Design Patterns are repeatable & reusable solutions for commonly occurring problems in the software/architectural design and they encourage the developers to design a highly cohesive and loosely coupled applications. Design patterns can be
Overview: In this tutorial, I would like to show you the gRPC Spring Boot Integration for inter microservices communication. gRPC is a RPC framework implementation from google for client-server application development. We have discussed gRPC, protobuf and their advantages for inter microservices communication in these articles before. If you have not read them, check them
Overview: In this Project reactor series, Lets take a look at switchOnFirst and its usage. If you are new to reactive programming, take a look at these following articles in the given order. Reactive Programming – A Simple Introduction Reactive Programming – Creating Sequences – Flux vs Mono Reactive Programming – Publisher Types – Cold
Overview: In this tutorial, I would like to show you passing messages between services using Kafka Stream with Spring Cloud Stream Kafka Binder. Spring Cloud Stream: Spring Cloud Stream is a framework for creating message-driven Microservices and It provides a connectivity to the message brokers. Something like Spring Data, with abstraction, we can produce/process/consume data
Overview: Applications have become very complex & user’s expectations have changed over the years! Applications nowadays have to be resilient and fault tolerant. It is easy to scale in / out our applications when they are designed stateless. But what about Database? Database is supposed to be a stateful application! How can we scale out
Overview: Over the years, MicroServices have become very popular. They are smaller, modular, easy to deploy and scale etc. However MicroService architectures do have some challenges. MicroServices have specific responsibilities. In order to complete an application workflow / a task, multiple MicroServices might have to work together. For example, an user would like to buy
MicroServices – How To Share DTO (Data Transfer Objects)Read More »
Overview: In this tutorial, I would like to quickly show you Reactor Flux File Reading example. How we could access a file, read the content stream and close the file etc with Project Reactor – to properly consume and cleaning up resources. We have been discussing reactive programming in this blog for a while. There
