When we talk about event-driven architectures, we often focus on things like loose coupling, scalability and DDD. But under the hood, the way consumers receive events matters just as much. And it usually comes down to one of two models: push vs poll. Your choice dictates what service(s) you use and how you handle errors. So, in this article, let’s compare the two models and understand their pros & cons. The post Understanding push vs poll in event-driven architectures appeared first on theburningmonk.com.

Serverful (i.e. paying for uptime) services like RDS makes working with ephemeral environments more difficult and poses a cost concern. In this artcile, let's see how Neon's Serverless Postgres database solves this problem and how we can clone an existing database instantly by branching from it. We will see how Neon differs from Aurora Serverless v2 and give you a step-by-step guide on how to use Neon with ephemeral environments in both your day-to-day feature development work, as well as in CI/CD pipeline[...]

What if you don't have to worry about event versioning or catching breaking changes anymore? What if event consumers are no longer coupled to the schema of the event and instead, subscribe to their semantics? I discovered an exciting new way to manage event schemas that will blow your mind!

Building Evolua, an AI-powered code reviewer, taught us a lot about balancing cost, performance, and developer experience. While selecting the right LLM and crafting prompts is important, the real challenge lies in handling large PRs, mitigating model limitations, and ensuring a smooth user experience. In this post, we break down our architecture, why we chose Bedrock, and key lessons learned - like why the LLM is actually the easy part. If you're using AI to write code, Evolua can help catch bad code befo[...]

"High cohesion, low coupling" is one of the most cited, and yet, most misunderstood principles in software engineering. So in this short post, let's explain their difference with a few easy-to-understand examples. The post Cohesion vs. Coupling appeared first on theburningmonk.com.
