If you are one of those people that think most of the products featured on HighScalability use way too many servers then you'll love this story: 130 VMs serving less than 10,000 users daily were chopped down to just one machine.
Here's the setup. A smallish website was having problems. Users were unhappy. In the balance was not only the product, but the company. The site was built using Angular, Symfony2, Postgres, Redis, Centos, 8 HP blades with 128 G RAM each, two racks, a very large HP 3par storage array, a 1Gbps uplink, and VMWare.
More than enough power for the task at hand. Yet the system couldn't handle the load. What would you do?
That's the story Jacques Mattheij tells in his very entertaining and educational Saving a Project and a Company article.
Jacques says much was right about the website, but time pressure and mismanagement created big problems at the system level. "A single clueless person in a position of trust with non technical management, an outsourced project and a huge budget, what could possibly go wrong?" Sound familiar?
