The Yelp's Platform-as-a-service distributed system PaaSTA is highly available and used to build, deploy, and run services using containers such as Docker and Apache Mesos. PaaSTA is designed and developed by Yelp and has been recently open sourced. You can take a look at the open sourced repository at the following URL: https://github.com/yelp/paasta
This is a suite for developers to specify how they want their code from their Git repository to be built, deployed, routed, and monitored. Yelp has used PaaSTA for more than a year to power its production-level services. PaaSTA is best suited if you have a strict production environment, such as Yelp, which requires many tiny microservices and where rolling out a new piece of code should be seamless and not disturb production systems. PaaSTA helps automate this entire process.
