We just celebrated our 7th birthday at Linux Academy with a trivia challenge! Let’s just say some of us enjoyed it more than others. Click here to see why. But, beware… things get really hot!
Just a short week later, we’re celebrating 6 years of Docker! Docker has led the container revolution and become the most popular container runtime over the past 6 years. Click here to participate in Docker’s show-and-tell celebrations around the world!
Why We Love Docker
- Docker reduces infrastructure requirements saving you money. Docker easily automates the packing, distributing, and managing of applications inside containers using fewer resources.
- Each container is secure and segregated from each other. This grants you complete control over traffic flow and management. If one container happens to be compromised, this won’t affect the others.
- Docker is fast. You can have multiple containers up and running in seconds rather than configuring and waiting for a virtual machine to boot up.
- Docker is open source. You can extend or manipulate it to meet your exact needs, whatever they may be.
- In March of 2013, Solomon Hykes introduced Docker in a PyCon Lightning talk.
- 4 years later in October 2017, Docker integrated Kubernetes into their enterprise edition.
- Then, just last year, Docker was named a Leader in The Forrester New Wave™: Enterprise Container Platform Software Suites, Q4 2018 evaluation.See Docker’s other milestones here!
Docker now has over 37 billion container downloads, over 3.5 million Dockerized apps, and over 200 active Docker user groups.
