Switched from development to ops team few years ago to become first DevOps at Brainly - biggest social learning network. Since then I've been improving my skills in ops area to manage, improve and design both bare metal and cloud based infrastructures.
Creating infrastructure for global web and mobile applications can be hard. Creating infrastructure for fast growing global applications can be very hard :) In brainly we had to move from traditional LAMP setup with bare metal servers to something new and cloud was not enough. With software like ansible, mesos, docker, consul, we have designed fully automated immutable setup, even with tests! On this presentation we will show you how, and share with you our exeperince with running this kind of platform.
