Mikro’s Serverless Saga: From Microservices to Madness and back

This is part 2 of a humor-inspired take on Monoliths to microservices that I wrote a few years back: https://blogs.justenougharchitecture.com/monos-journey-from-monolith-to-microservices/. If you did not read that, please do so first.

Mikro was serving his consumers as always. He consistently met his promises (SLAs), and his life was good. Suddenly, he felt a stab and excruciating pain. “Damnit, what was that?” he said. To Mikro’s horror, he found himself being sliced and diced into smaller and smaller pieces. “But I thought I was already micro enough!” he wailed as functions were extracted from his very being.

Vault for storing secrets (plus Spring Boot & Mongodb)

So this is a mix of a couple of howtos. First, we have a simple Spring Boot app that retrieves some data from a MongoDB database that has authentication enabled to access it. Next, we will see how to store secrets in a Vault implementation and then programmatically access it (in our case the user ID and password to access the database).

Using Spring Boot to invoke ChatGPT/OpenAI API

OpenAI provides us the ability to invoke its features via RESTful APIs. This blog shows how to invoke the API using Spring Boot. There is nothing special here and no OpenAI Java libraries that I use. One can do the same in standard Java (non-spring) or even in more concise code with Nodejs. But here goes a sample with Spring Boot.

ChatGPT, BARD – AI to write blogs & entire apps (the future is coming)

So it’s been some time since I wrote a blog. As I was figuring out what my next blog is, how could I ignore ChatGPT, BARD and the AI excitement that it has brought about (or re-awakened among many of us). And then there is GitHub’s Copilot and AWS CodeWhisperer! Code assistants that can make us slightly more efficient developers.
