Based in Vancouver, Canada, Hootsuite is the most widely used SaaS (software as a service) platform for managing social media. Since its humble beginnings in 2008, Hootsuite has grown into a billion-dollar company with more than 15 million users around the globe. As Hootsuite evolved over the years, so did the technology stack. A key change was moving from LAMP (Linux, Apache, MySQL, PHP) to microservices. A shift to microservices didn't come without its challenges, however.
