Containers vs Virtual Machines

Pack many more containers on a host machine than you can virtual machines

Each VM is a self-contained system in its own right, with its own operating system and virtualized hardware and its own unique resources.

…result is significantly faster deployment, much less overhead, easier migration, faster restart

Containers Advantages

SecureContainers isolate applications from each other and the underlying infrastructure while providing an added layer of protection for the application.

OpenDocker containers are based on open standards allowing containers to run on all major Linux distributions and Microsoft OS with support for every infrastructure..

LightweightContainers running on a single machine all share the same operating system kernel so they start instantly and make more efficient use of RAM.

Orchestration

Enables the definition of simple multi-container applications

Docker Compose

Manages and organizes Docker containers across multiple hosts via the same API used by a single Docker host

Docker Swarm

Orchestration and management solution that actually predates Docker, but has recently added support for Docker into its built-in application framework Marathon.

Mesos – DC/OS

DeisOpen source PaaS platform to deploy and manage applications integrated with Docker

Open-source solution built by Google offering container grouping into “Pods” for management across multiple hosts, also supported on Azure
