Docker vs OpenStack: What are the differences?

What is Docker? Enterprise Container Platform for High-Velocity Innovation. The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere.

What is OpenStack? Open source software for building private and public clouds. OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.

Docker and OpenStack are primarily classified as "Virtual Machine Platforms & Containers" and "Open Source Cloud" tools respectively.

Some of the features offered by Docker are:

  • Integrated developer tools
  • open, portable images
  • shareable, reusable apps

On the other hand, OpenStack provides the following key features:

  • Compute
  • Storage
  • Networking

"Rapid integration and build up" is the primary reason why developers consider Docker over the competitors, whereas "Private cloud" was stated as the key factor in picking OpenStack.

Docker is an open source tool with 53.8K GitHub stars and 15.5K GitHub forks. Here's a link to Docker's open source repository on GitHub.

Lyft, StackShare, and Shopify are some of the popular companies that use Docker, whereas OpenStack is used by PayPal, HubSpot, and Wikipedia. Docker has a broader approval, being mentioned in 3471 company stacks & 3322 developers stacks; compared to OpenStack, which is listed in 66 company stacks and 50 developer stacks.

over
DockerDocker

lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.

    What are some alternatives to Docker and OpenStack?
    LXC
    LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers.
    rkt
    Rocket is a cli for running App Containers. The goal of rocket is to be composable, secure, and fast.
    Kubernetes
    Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
    Cloud Foundry
    Cloud Foundry is an open platform as a service (PaaS) that provides a choice of clouds, developer frameworks, and application services. Cloud Foundry makes it faster and easier to build, test, deploy, and scale applications.
    Vagrant
    Vagrant provides the framework and configuration format to create and manage complete portable development environments. These development environments can live on your computer or in the cloud, and are portable between Windows, Mac OS X, and Linux.
