Google (GOOG) has been building out its containerization strategy recently, and the latest development is the beta release of Google Container Registry, which the company describes as a service offering secure hosting, sharing and management of private container repositories.

This follows on the previous week’s announcement from Google about the introduction of container technologies on Google Cloud Platform. The Google cloud provides container support through the Google Container Engine, a service powered by Google project Kubernetes, but with Container Registry, Google is hoping to provide additional benefits to customers and partners.

As Google’s Pratul Dublish, technical program manager, explained it in a blog post, there are three key benefits that Google Container Registry provides to Google Cloud Platform customers:

“Docker registry availability, security, performance, and durability become more and more critical as more of our Compute Engine applications are containerized with Docker. Private registries help, but they need valid certificates, authentication and firewalls, backups, and monitoring. Google’s container registry provides us with a complete Docker registry that we integrate into our development and deployment workflow with little effort,” said Steve Reed, principal engineer of core engineering at zulily, an early adopter of the service, in a prepared statement.

Google is a little behind some of its competitors when it comes to container support, but the company is getting there and is adding support for containers. Docker is still the big name in containerization, and having support for that technology is the first step is making customers and partners happy.
