OpenStack vs Packer: What are the differences?

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.

What is Packer? Create identical machine images for multiple platforms from a single source configuration. Packer automates the creation of any type of machine image. It embraces modern configuration management by encouraging you to use automated scripts to install and configure the software within your Packer-made images.

OpenStack belongs to "Open Source Cloud" category of the tech stack, while Packer can be primarily classified under "Infrastructure Build Tools".

Some of the features offered by OpenStack are:

  • Compute
  • Storage
  • Networking

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

  • Super fast infrastructure deployment. Packer images allow you to launch completely provisioned and configured machines in seconds, rather than several minutes or hours.
  • Multi-provider portability. Because Packer creates identical images for multiple platforms, you can run production in AWS, staging/QA in a private cloud like OpenStack, and development in desktop virtualization solutions such as VMware or VirtualBox.
  • Improved stability. Packer installs and configures all the software for a machine at the time the image is built. If there are bugs in these scripts, they'll be caught early, rather than several minutes after a machine is launched.

"Private cloud" is the primary reason why developers consider OpenStack over the competitors, whereas "Cross platform builds" was stated as the key factor in picking Packer.

Packer is an open source tool with 9.1K GitHub stars and 2.47K GitHub forks. Here's a link to Packer's open source repository on GitHub.

According to the StackShare community, Packer has a broader approval, being mentioned in 115 company stacks & 21 developers stacks; compared to OpenStack, which is listed in 67 company stacks and 50 developer stacks.

After a machine image is built, that machine image can be quickly launched and smoke tested to verify that things appear to be working. If they are, you can be confident that any other machines launched from that image will function properly.
