Containers
Containers
Linux containers is a generic term for an implementation of operating system-level virtualization for the Linux operating system. Currently, a number of such implementations exist, and they are all based on the virtualization, isolation, and resource management mechanisms provided by the Linux kernel, notably Linux namespaces and cgroups.

Containers :: Runtime
The Open Container Initiative (OCI) is a lightweight, open governance structure (project), formed under the auspices of the Linux Foundation, for the express purpose of creating open industry standards around container formats and runtime. The OCI was launched on June 22nd 2015 by Docker, CoreOS and other leaders in the container industry. The OCI currently contains two specifications: the Runtime Specification (runtime-spec) and the Image Specification (image-spec). The Runtime Specification outlines how to run a “filesystem bundle” that is unpacked on disk. At a high-level an OCI implementation would download an OCI Image then unpack that image into an OCI Runtime filesystem bundle. At this point the OCI Runtime Bundle would be run by an OCI Runtime.

CRI-O
CRI-O is an implementation of the Kubernetes CRI (Container Runtime Interface) to enable using OCI (Open Container Initiative) compatible runtimes. It is a lightweight alternative to using Docker as the runtime for kubernetes. It allows Kubernetes to use any OCI-compliant runtime as the container runtime for running pods. Today it supports runc and Clear Containers as the container runtimes but any OCI-conformant runtime can be plugged in principle. CRI-O supports OCI container images and can pull from any container registry. It is a lightweight alternative to using Docker, Moby or rkt as the runtime for Kubernetes. Homepage
Intel® Clear Containers
When the Intel® Clear Containers project launched in 2015, our goal was to address security concerns within containers through Intel® Virtualization Technology (Intel® VT). Using Intel VT, we were able to launch containers as lightweight virtual machines (VMs), providing an alternative runtime, which is interoperable with popular container environments such as Kubernetes and Docker. As announced on December 5, 2017 , The Intel Clear Containers project has joined the Kata Containers project, under open governance at the OpenStack* Foundation.

Mesos
What is Mesos? A distributed systems kernel. 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.
