"There was no risk of lock-in with Canonical’s OpenStack. It’s close to the upstream version, so we have the freedom to fully support internally, if we want to."

"We are working with Canonical to ensure we are properly supported as we scale out our Ubuntu cloud. In particular, we are looking at the Ubuntu Advantage service, which gives us access to Canonical support engineers and Openstack contributors working at Canonical, whenever we ever need them."

"Now that we have teams in Montreal, India and Japan it is important for us to have the right system and tools in place so that we can work effectively and efficiently between geographies. We can’t afford to have delays simply because the teams are distributed."

"Ubuntu had good support for our fibre channel and integrated very well with our Active Directory."

"We’re reinventing how we scale by becoming simpler and modular, similar to how applications have evolved in cloud data centers. Open source and OpenStack innovations represent a unique opportunity to meet these requirements and Canonical’s cloud and open source expertise make them a good choice for AT&T."

"When we discovered that Canonical was offering a new, extended support package, we didn’t hesitate to sign up. ESM effectively rendered the security problem a non-issue."

"We use Ubuntu primarily because it is such a stable and reliable operating system. ESM builds on this foundation even further, and helps us deliver an even better service to our clients."

"A new wave of workloads demand breakthrough efficiencies in density, energy, and operational costs which can be scaled to a customer’s IT environment."

"That was straightforward because Ubuntu is the most open of the open source distributions."

"The ability to go from development to production on the same OS, with the same tools and interface, is invaluable. In fact, it was the main factor in our decision."

"The joint GOSH-ICH website represents the public-facing image of both institutions and is often the first point of contact the public has with us. The website aims to promote our identity, publicise our expertise and communicate our values and vision."

"The new solution is definitely saving us money. Licence costs aside, the fact that we have consolidated our server infrastructure makes a big difference. As well as reducing the number of servers we need to run our day-to-day operations from 11 to four, the new virtualization software means that we …

“We realised that open source was the best option and went for Fedora. While the first three years were certainly a success, we wanted to introduce an operating system that was easier to use but still offered the look and feel of a powerful computing environment, without sacrificing the budget.”

"His main area of concern is the cloud underlayer that can maximise the utilisation efficiency of the computer resources in the data centre, and the cloud networking which can federate various cloud services."

"His main area is developing container data centres with an outside-air cooling system. He is also trying to optimise power efficiency in cooperation with each computer resource and data center facility."
