Let's say you've been working on your project for awhile, but can't shake the feeling that it is performing sluggishly. More importantly, your client is also unhappy with the code's responsiveness. Remember, your code doesn't need to be fully optimized. 80% of the gains generally come from focusing on 20% of the code.

Imagine this scenario: you're responsible for integrating your company’s system with an old system from one of your clients. Every day, just when you think you've achieved it, the client’s system crashes and you have no idea why. You are so disappointed that you don’t even want to get a drink with your friends anymore, you just want to stay home thinking of ways to solve the problem. Well, that was my story - until I found Apache Camel and Apache Wicket.

Reactive Programming is a "chameleon"! :-) It can be understood as "a style of micro-architecture involving intelligent routing and consumption of events, all combining to change behaviour"¹; or it can be defined as "a programming paradigm oriented around data flows and the propagation of change"². It has something to do with the Reactive Manifesto. Functional programming comes to mind when thinking about reactive programming. And it is a software development field where a lot of interesting progress is being made! Lots to discuss here!

It was Todd Mcleod that said something like this… "The more I learn the harder it gets to ask questions, the more I ask questions the more I learn"

Functional programming paradigm and languages are usually associated with core features like pure functions and immutable data (structures)¹, and other properties like referential transparency, higher-order (first order) functions, lazy evaluation, and recursion². They arguably provide programmers with better tools and abstractions to deal with difficult actual problems that involve concurrency, parallelism, big data, etc.

DevOps has become the practice du jour among innovative IT departments. But what does it look like day to day? And how did it evolve over time? Below, I'll explore some tools and platforms that help enhance your DevOps practice.
