Microservices

Implementing a Service Mesh with Istio in a Kubernetes cluster is like adding a superpower to your microservices architecture. It’s akin to giving your services a cape and a utility belt, making them more resilient, secure, and manageable. In this article, we’ll dive into the nitty-gritty of setting up Istio in your Kubernetes cluster, complete with code examples and diagrams to guide you through the process. Why Service Mesh? Before we jump into the implementation, let’s quickly address why you might need a Service Mesh....

Introduction to Contract Testing In the world of microservices, where each service is a tiny, independent piece of a larger puzzle, ensuring that these pieces fit together seamlessly is crucial. This is where contract testing comes into play, acting as the glue that holds your microservices architecture together. Imagine contract testing as the ultimate matchmaker, ensuring that each microservice knows exactly what to expect from its counterparts. What is Contract Testing?...

Введение в Тестирование Договоров В мире микросервисов, где каждый сервис является небольшим, независимым фрагментом более крупной головоломки, обеспечение того, чтобы эти фрагменты идеально сочетались, имеет решающее значение. Именно здесь на сцену выходит тестирование договоров, выступая в роли клея, который держит вместе вашу архитектуру микросервисов. Представьте тестирование договоров как идеального посредника, гарантирующего, что каждый микросервис точно знает, чего ожидать от своих аналогов. Что такое Тестирование Договоров? Тестирование договоров — это техника, которая фокусируется на проверке взаимодействий между микросервисами путем определения договора, который конкретизирует входные и выходные данные каждого сервиса....

Introduction to Backpressure In the world of microservices, managing load effectively is crucial for maintaining system stability and performance. One powerful pattern for achieving this is Backpressure, which allows the receiver to control the flow of data from the sender. This mechanism is particularly useful in scenarios where the receiver is overwhelmed by the volume of incoming data, helping to prevent system crashes and ensure smooth operation. Understanding Backpressure Backpressure is a design pattern that helps in managing the flow of data through a system, especially when the receiver is unable to process the data as quickly as it is being sent....

What is gRPC? Imagine you’re at a high-speed racing track, and instead of driving a vintage car, you’re behind the wheel of a sleek, modern sports car. That’s what gRPC feels like compared to traditional REST APIs. Introduced by Google in 2015, gRPC is a modern, high-performance RPC (Remote Procedure Call) framework designed to facilitate communication between client and server using Protocol Buffers and HTTP/2. Protocol Buffers: The Secret Sauce Protocol Buffers, or protobufs, are the data exchange format that makes gRPC so efficient....
