Many of us remember when virtualization was in its infancy, when we didn’t have features like high availability to protect against hardware failures, and live migration to move a virtual server off of the host it resided on for maintenance.  Back then, the benefits were all about reduced power and cooling requirements, and using less …

I’ve already talked about one of OpenStack’s core building blocks, Cinder, which is OpenStack’s block based storage feature.  Now, I want to take a closer look at Swift, OpenStack’s object based storage project, and another key component to an OpenStack deployment. Swift enables the storage and retrieval of data by using a simple API.  It …

When we talk about OpenStack, there is a lot of focus on the Continuous Integration/Continuous Deployment (CI/CD) methodology it uses to achieve its rapid release schedule of two releases a year.  Think about that for a moment, a network of thousands of developers working together to release an operating system that runs clouds.  Clouds that …
