Amazon Web Services, the largest public cloud provider, announced today that the Docker Trusted Registry software — a tool for storing and managing container images that can be used to run applications — is now available in the AWS Marketplace.

Docker Trusted Registry, formerly known as Docker Hub Enterprise, is the enterprise-focused software from hot billion-dollar startup Docker that became generally available in June. Engineers and admins have been able to buy it on the Microsoft Azure Marketplace, and IBM said it would resell the software, too.

“This new offering supports the popular laptop-to-cloud workflow by giving you a central, highly accessible location to store and manage your Docker images for deployment in your chosen on-premises or cloud environment,” AWS chief evangelist Jeff Barr wrote in a blog post today. “You can create custom access control levels and use them to regulate access to the images in your registry. You can require the use of SSL certificates or LDAP entries, and you can take advantage of all of the network access controls that are part of the Virtual Private Cloud (VPC).”

Docker has popularized the deployment of applications in containers, several of which can run on a single physical server. The open-source Docker container technology has picked up adoption among developers and is thought of as a lightweight alternative to more mature virtual machine technology from VMware, Microsoft, and other companies.

AWS itself, of course, offers the EC2 Container Service for deploying containers onto the AWS public cloud to run applications. IBM and Google have similar container deployment tools, too. A trusted place for storing critical containers, not just the public Docker Hub, is the next piece to become important across clouds.

Of course, Docker also needs many platforms on which it can sell its commercial software. Docker recently brought on a new CFO, Mike Gupta, who had been the CFO at Twitter.
