Greater resource efficiency: With containers, you can run several times as many copies of an application on the same hardware as you can using VMs.

gigabytes for some VMs), make better use of hardware capacity, and have faster startup times. Container sizes are measured in megabytes (vs.

Lighter weight: Unlike VMs, containers don’t carry the payload of an entire OS instance and hypervisor they include only the OS processes and dependencies necessary to execute the code.

These capabilities - such as control groups (Cgroups) for allocating resources among processes, and namespaces for restricting a processes access or visibility into other resources or areas of the system - enable multiple application components to share the resources of a single instance of the host operating system in much the same way that a hypervisor enables multiple virtual machines (VMs) to share the CPU, memory and other resources of a single hardware server.Īs a result, container technology offers all the functionality and benefits of VMs - including application isolation, cost-effective scalability, and disposability - plus important additional advantages: How containers work, and why they're so popularĬontainers are made possible by process isolation and virtualization capabilities built into the Linux kernel.

and many other organizations and individuals contribute. Docker is essentially a toolkit that enables developers to build, deploy, run, update, and stop containers using simple commands and work-saving automation through a single API.ĭocker also refers to Docker, Inc. (link resides outside IBM), the company that sells the commercial version of Docker, and to the Docker open source project (link resides outside IBM), to which Docker, Inc. Containers simplify delivery of distributed applications, and have become increasingly popular as organizations shift to cloud-native development and hybrid multicloud environments.ĭevelopers can create containers without Docker, but the platform makes it easier, simpler, and safer to build, deploy and manage containers.

It enables developers to package applications into containers-standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment. What is Docker?ĭocker is an open source containerization platform. Learn about containers, how they compare to VMs, and why Docker is so widely adopted and used. Docker is an open source platform for building, deploying, and managing containerized applications.
