= Understanding Containers
|
|
|
|
The basic units of {product-title} applications are called _containers_.
|
|

|
|
are lightweight mechanisms for isolating running processes so that they are
|
|
limited to interacting with only their designated resources.
|
|
|
|
Many application instances can be running in containers on a single host without
|
|
visibility into each others' processes, files, network, and so on. Typically,
|
|
each container provides a single service (often called a "micro-service"), such
|
|
as a web server or a database, though containers can be used for arbitrary
|
|
workloads.
|
|
|
|
The Linux kernel has been incorporating capabilities for container technologies
|
|
for years. {product-title} and
|
|
Kubernetes add the ability to orchestrate containers across
|
|
multi-host installations.
