The first part of every development effort is a proof of concept (POC) to demonstrate the concept and prove it possible. Since it’s built quickly and with a specific goal of showing the user, the back-end doesn’t get much love. It is usually minimal, just enough to get the POC to run.
If the concept gets approved, a slew of new requirements require the team to keep moving forward on enhancing the POC. Sometimes this works out fine; however sometimes it doesn’t. When it comes down to making systems that process data, building it on a distributed model with easy parallel processing is the key to scaling easy.
Trust me when I tell you; spending a few cycles on building in parallelism into your application before you start writing code to process your data is much easier than later retrofitting your code with it. Here are a few tips:
