Microservices

An example of how a Lambda container image can help standardise service deployments — The background Ever since the inception of Lambda support for container images, I hadn’t encountered a specific need for them, and I had been wondering how much added value the acclaimed feature brought. Why not stick to the fit-for-purpose ECS?, I thought. Yes, Lambda does not support every single runtime out there…

To deliver consistency across various platforms — Saga is the most common pattern for ensuring cross-service data consistency. It splits a global transaction into multiple subtransactions. If all subtransaction operations succeed, then the global transaction succeeds, and if one subtransaction still fails after retries, then all executed subtransactions are compensated. The above process is simple and clear…

Previously, I have introduce how to shift from a monolith to CQRS in order to solve some problems. As the architecture gets bigger, the maintenance effort gets higher, so it is necessary to split the monolith into several execution units to reduce the development difficulty. However, CQRS can be used…

A Microservice is not just breaking a big monolithic application into sub-applications, it’s a lot more than that. The concept and epicenter of Microservices revolve around creating a self-contained piece of functionality that offers clear interfaces and could have its own internal components. For more details on microservices and their…

We love working with Rust in my team at Lumen®, where we develop the backend infrastructure for the Lumen® Mesh Delivery and Lumen® CDN Load Balancer technologies: it is a language that boasts great performance, brings valuable compile-time guarantees and is very expressive and feature-complete. However, when we recently needed…

Lately i have been working extensively on kafka related work where i need to test, debug the issues that i encounter during that time. It was getting very difficult to do without having a kafka standalone cluster in local system. Then i was looking of ways through which i can…

There are millions of articles that say how great microservices are and how awesome it is to use them from several points of view, but this article is not meant to measure the greatest of the microservices infrastructure but tell you the real cost, that nobody is telling/displaying you about…

Why a Service Mesh is used with applications architected as distributed collections of micro services — A service mesh it’s an infrastructure layer allowing the control of how independent parts of an application communicate. It’s a layer dedicated to the business logic of an application. Is it a solution to manage communication when moving from monolithic architectures to micro services in a Kubernetes cluster where:
