Paasta is Yelp's platform for running services, built on Docker, Mesos, Marathon, SmartStack, git, and Jenkins. It provides all the neat features you'd expect from a PaaS, but provides pragmatic solutions to real-world problems. Learn how we migrated from our legacy deployments to Paasta, enabled self-service creation of new services, and addressed other hard problems like monitoring, testing, safe deploys in a hybrid, multi-region, multi-environment world.
