6. Deploying WSO2 Middleware
on Apache Mesos

7. An Introduction to Apache Mesos
● An open-source cluster manager that was developed at
the University of California, Berkeley
● It "provides efficient resource isolation and sharing across
distributed applications, or frameworks
● Twitter, Airbnb, Apple and over 50 organizations use
Mesos.
https://en.wikipedia.org/wiki/Apache_Mesos

8. Apache Mesos Features
● Scalability to 10,000s of nodes
● Fault-tolerant replicated master and slaves using ZooKeeper
● Support for Docker containers
● Native isolation between tasks with Linux Containers
● Multi-resource scheduling (memory, CPU, disk, and ports)
● Java, Python and C++ APIs for developing new parallel
applications
● Web UI for viewing cluster state
