In this post, I will give an overview about how to write event-driven distributed systems in Go, with gRPC, NATS JetStream and CockroachDB. As a Go developer and a solutions architect, my favorite technologies include gRPC, NATS ecosystem and CockroachDB amongst several technologies. I will use these technologies to demonstrate…

In this post, I will give a brief introduction to NATS JetStream as a distributed event streaming system, which comes from the NATS ecosystem. In a nutshell, NATS JetStream is a distributed streaming system with publish/subscribe as the messaging pattern. When I introduce NATS to my clients in my consulting…

In this post, I will share my experience of working as a consulting solutions architect and a mentor on Go programming language and distributed systems architectures, in India, and I will also share some of my recommendations based on my experience, when you adopt Go in your organisations. I am…

I have been working as a consultant and trainer on Go programming language and distributed systems architectures, in India, and guided a lot of software development teams to adopt Go for building their systems.

Update on 16-May-2022: This post has been updated with a new post Building Event-Driven Distributed Systems in Go with gRPC, NATS JetStream and CockroachDB In this post, I will demonstrate a simple Event Sourcing/CQRS Example in Go to demonstrate how to solve the practical challenges of Microservices based distributed systems…

In this post, we’ll take a look into how to write gRPC Interceptors in Go. When you write HTTP applications, you can wrap route specific application handlers with HTTP middleware that let you execute some common logic before and after executing application handlers. We typically use middleware to write cross-cutting…

Here’re some technology predictions for 2018 based on my technology focus and interesting areas: Kubernetes, the open source container orchestration engine, will be the technology of 2018 in all aspects. Kubernetes, one of the most successful projects in the history of open-source ecosystem, will be the “new Linux” in cloud…
