Behind the tech that saved YouTube from a scalability nightmare

Back in 2010, YouTube was in a fix. The platform was growing fast and its infrastructure couldn’t match its pace. Pumping in more CPU and memory wasn’t helping; it was still falling apart at the seams. 

That’s when two YouTube engineers, Sugu Sougoumarane and Mike Soloman decided to take a step back and analyse the problem from a different perspective: “When we actually sat down and wrote a huge spreadsheet of all problems and solutions, and when we looked at all that, it was obvious that we needed to build something that sits between the application and the MySQL layer, and moderate all these queries,” says Sugu in a sit-down with TechRadar Pro on the sidelines of the Percona Live Conference Europe 2019 in Amsterdam.
