 Hi my name is Raj. A big part of being an operation engineer is managing a cluster of machine. This can be your web server, your cache server or your Hadoop cluster. A static set of machine runs a static set of applications. So you have some machines which are at 80% CPU utilization and some machines which are at 10% CPU utilization. If an operation engineer ends up managing the cluster of grids and the uptight, Mesos provides a way of solving this problem. It allows us to think in terms of resources like CPU, storage and memory instead of thinking in terms of static host. I will be presenting a case study of migrating the URL shortening service of Twitter from physical from static host to Mesos. If you have been thinking of increasing your machine utilization and reducing your operational cost, this talk is for you. You will learn about the benefits and the issues to be aware of when migrating to Mesos.
