Microservices is an architecture pattern that is realized through a set of patterns and technologies. This article sets the foundation for our series which helps in understanding each of these patterns along with their sample implementations. Our exercise-driven learning series is based on Spring Boot, Spring Cloud, and the related technologies. — Before we jump into the world of Microservices, let's spend some time understanding the fundamentals. As it involves, a multitude of technologies, it's easy to lose track. …

In this article, we are going to understand the fundamentals of Centralized Configuration Service based on Spring Cloud Config. We will do the sample implementation based on Spring Boot & Spring Cloud. — Spring Cloud Config is one of the Spring Cloud Projects. This is directly mapped to one of the important patterns of Microservice Architecture — Centralized Configuration Service. This provides the means to centralize and manage the externalized configurations across different applications/services in a distributed system.

In this article, we will try to understand the fundamentals of Spring Cloud Gateway which represents one of the most important patterns in the Microservices Architecture — API Gateway. We will create sample implementations based on Spring Boot & Spring Cloud Gateway. This is the fifth part of our Spring Boot Microservices series. — API Gateway Spring Cloud Gateway provides a library to build an API Gateway. This is the preferred gateway implementation provided by Spring Cloud. It's built with Spring 5, Spring Boot 2, and Project Reactor.

In this article, we will learn the fundamentals of one of the must pattern in the Microservices world — Circuit Breaker. We will do the sample implementation based on Spring Boot, Spring Cloud & Resilience4j. This is the sixth part of our Spring Boot Microservices series. — What is Circuit Breaker? As the name suggests, the pattern derives its inspiration from the electrical switches, which are designed to protect an electrical circuit from damage, caused by excess current from an overload.

In this post, I will provide a quick overview of Amazon Q, its features and capabilities from a developer perspective. — Today morning, when I opened up my visual studio code, I was surprised to find Amazon Q, plugged-in to my IDE. I tried to play around with it, and found it very useful. Especially if you are a developer and dealing with AWS technologies. In this post, I will provide…

In this post, I will demonstrate how to use Aspects feature in an AWS CDK Application — Overview Aspects are a way to apply a set of instructions or logic to all the constructs in a given scope, in an AWS CDK application. For instance, let’s say, you want to ensure that all the AWS S3 buckets inside a given CDK stack are encrypted. You can create a…

In this post, I will walk through the concept of CDK Context in AWS CDK — Overview Context values are key-value pairs that can be associated with a CDK App, Stack, or any other CDK construct. The context keys are specified as strings. And the values can be specified in any supported JSON type including numbers, strings, arrays, or objects. CDK Context is used in variety of…

In this post, I will discuss the testing options and assertion utilities provided by AWS CDK — Overview AWS CDK provides the framework to develop your IaC (Infrastructure as a Code) in a programming language, like Typescript. This makes the CDK application, as testable as any other business application. For instance, if CDK applications are built with typescript, you can use Jest, which is a popular javascript testing…

In this post, we will discuss the best practices to develop CDK constructs which are the building blocks of your AWS CDK applications. — Best Practices AWS CDK provides the platform to develop the cloud infrastructure code with the help of a programming language like Javascript, Python, etc. Constructs are the key components in AWS CDK which help in defining the AWS resources. For instance, if we talk about AWS S3, there would be a CDK…
