Not so DDoS

by in Feature Articles on

Joe K was a developer at a company that provided a SaaS Natural Language Processing system. As Chief Engineer of the Data Science Team (a term that make him feel like some sort of mad professor), his duties included coding the Data Science Service. It provided the back-end for handling the complex, heavy-lifting type of processing that had to happen in real-time. Since it was very CPU-intensive, Joe spent a lot of time trying to battle latency. But that was the least of his problems.

The rest of the codebase was a cobbled-together mess that had been coded by the NLP researchers- scientists with no background in programming or computer science. Their mantra was “If it gets us the results we need, who cares how it looks behind the scenes?” This meant Joe’s well-designed data service somehow had to interface with applications made from a pile of ugly hacks. It was difficult at times, but he managed to get the job done while also keeping CPU usage to a minimum.
