We’re three and a half years into OpenStack® and there is still confusion about exactly what OpenStack is, how to compare OpenStack to other cloud platforms, and specific use cases for OpenStack. I find myself having the same conversations over and over again in an attempt to debunk the myths and misperceptions in the market. There are a number of them, but to help people who are still getting up to speed with OpenStack, let’s focus in on the three largest.
Developers have been buzzing lately about how virtualization containers can boost scale while lowering costs. We are big fans of containers and the ways that they simplify the deployment and management of cloud applications. We think the next step is containerizing and virtualizing the application, not just the machine.
There are a lot of good reasons to be excited about containers, a form of operating system-level virtualization with many applications. At Mailgun, we’re excited about containers for four major reasons:
VMworld 2013 was an enormous success for VMware. It attracted 22,500 attendees from all over the world. Its sheer magnitude cements VMworld’s spot among the biggest enterprise IT infrastructure conferences. In my view it is THE EVENT OF THE YEAR for anyone involved in IT operations, whether they are a technology provider, a service provider or an SI partner.
The concept of virtualization makes cloud computing possible and plenty of people are familiar with machine-level virtualization hypervisors such as Xen, KVM and VMware. Machine-level virtualization is an intuitive abstraction level for a lot of enterprise computing workloads because it makes one server look like many servers. Yet there’s a growing interest in operating system-level virtualization and new projects are emerging to take advantage of the unique properties of this technology for cloud computing.
I joined Rackspace 27 months ago as one of about 2,000 Rackers. At that time, the company had a vision of a cloud powered by OpenStack that would give you, our customers, the best of cloud, dedicated and virtualized technologies. It was mostly a vision – OpenStack had been born only a few months before.
