DockerCon sailed through Seattle recently, leaving behind in its wake a new swath of rapid adopters plus a trail of related company and product announcements. Docker itself produced perhaps the most exciting
Docker’s rapid adoption and deep penetration signal the beginning of the end for the Puppet and Chef IT automation platform.
Computerword – Puppet and Chef make way for Docker
Docker usage has quintupled in a single year — following the patter of most-hyped technologies, according to a recent study by Datadog, a monitoring and analytics platform. But this raises some questions: Can this growth be sustained? And, if so, what will be the likely patterns of adoption?

Nice analagy from Mike Coleman about the underlying architecture of Docker.
Houses (the VMs) are fully self-contained and offer protection from unwanted guests. They also each possess their own infrastructure – plumbing, heating, electrical, etc. Furthermore, in the vast majority of cases houses are all going to have at a minimum a bedroom, living area, bathroom, and kitchen. I’ve yet to ever find a “studio house” – even if I buy the smallest house I may end up buying more than I need because that’s just how houses are built. (for the pedantic out there, yes I’m ignoring the new trend in micro houses because they break my analogy)
Apartments (the containers) also offer protection from unwanted guests, but they are built around shared infrastructure. The apartment building (Docker Host) shares plumbing, heating, electrical, etc. Additionally apartments are offered in all kinds of different sizes – studio to multi-bedroom penthouse. You’re only renting exactly what you need. Finally, just like houses, apartments have front doors that lock to keep out unwanted guests.

Another new feature and revenue generator for Docker. This announcement officially integrates the features from Tutum (an acquisition made in Oct of 2015). Tutum is a cloud service used by developers and sysadmins to deploy and manage Docker applications.
Docker Cloud is where developers and IT ops meet to build, ship and run any application, anywhere. Over the past few months our team has been hard at work expanding on the features of Tutum and building native integration with Docker Hub, Docker ID (the new shared account system across all Docker services), Docker official repositories, and commercially supported Docker Engine (CS Engine).
Start using Docker Cloud today by logging in to Docker Cloud using your Docker ID.
