Apache Mesos is a cluster manager that provides efficient resource isolation and sharing across distributed applications, or frameworks. Mesos is built using the same principles as the Linux kernel, only at a different level of abstraction.
The Mesos kernel runs on every machine and provides applications (e.g., Hadoop, Spark, Kafka, Elasticsearch) with API’s for resource management and scheduling across entire datacenter and cloud environments.
Mesos plays well with existing container technologies (e.g., Docker) and also provides its own container technology. It also supports composing different container technologies (e.g., Docker and Mesos). The Composing containerizer allows multiple container technologies to play together.
This is free and open source software.
Features include:
- Linear scalability – industry proven to easily scale to 10,000s of nodes.
- High availability – fault-tolerant replicated master and agents using Zookeeper. Non-disruptive upgrades.
- Containers – native support for launching containers with Docker and AppC images. The Mesos containerizer allows tasks to be run with an array of pluggable isolators provided by Mesos. It provides lightweight containerization and resource isolation of executors using Linux-specific functionality such as control cgroups and namespaces. It is composable so operators can selectively enable different isolators.
- Pluggable isolation – first class isolation support for CPU, memory, disk, ports, GPU, and modules for custom resource isolation.
- Two level scheduling – support for running cloud native and legacy applications in the same cluster with pluggable scheduling policies.
- APIs – HTTP APIs for developing new distributed applications, for operating the cluster, and for monitoring.
- Web UI – built-in Web UI for viewing cluster state and navigating container sandboxes.
- Cross platform support – runs under Linux, macOS, and Windows. Cloud provider agnostic.
