Apache Mesos

Apache Mesos is an open-source cluster manager that provides efficient resource isolation and sharing across distributed applications or frameworks. It is designed to handle large-scale data center workloads by abstracting CPU, memory, storage, and other compute resources and offering a unified interface to manage and schedule tasks across clusters of machines.

Mesos architecture is based on two key components: the Mesos Master and Mesos Agents. The Mesos Master is responsible for managing the cluster's resources and scheduling the tasks that need to run on the agents. The Mesos Agents are responsible for running the tasks that the Mesos Master schedules.

Mesos also provides a pluggable framework for building and deploying distributed applications. This framework enables developers to build and run different types of distributed applications on top of Mesos, such as Hadoop, Spark, and Docker containers, among others.

Mesos is used by companies like Twitter, Airbnb, and Apple to manage their large-scale data center workloads. Its key benefits include improved resource utilization, better fault-tolerance, and simplified deployment and management of distributed applications.
