There is a lot of buzz about a “new” technology called Docker. I say “new” in quotes, because most of us greybeards should remember a technology called “containers,” circa 2004, and the arguments about which was better: virtualization or containers.
Well, it seems that the wheel has turned full circle, and we are back in that same place again. Somebody in the Linux world has invented Docker and marketed it. But what is it? Basically, Docker is a containerization tool for Linux—wait, déjà vu, there’s a glitch in the matrix. Substitute the word “Docker” for “Solaris Containers,” and you have the same beast. But now containerization is open source, so it must be right, because all the cool kids are talking about it. Continue reading Docker: What Is It? Hint: It’s Not a Harbour Worker→

Citrix Workspace Services, an all-encompassing Platform as a Service (PaaS) built on Microsoft Azure, will enable service providers and enterprises to offer Citrix virtualization and cloud services to their customers. It will be in tech preview later in 2014, and no release date has been announced.
With so many vendors in the virtualization marketplace, new products are released daily, and only some of them will ultimately prove to be successful.

Since around the turn of the century, I have had a motto that goes like this: “Virtualization is a journey, not a project.” It seems now would be a good time to bring that slogan up to date, changing the message to “The cloud is a journey, not a project.” It really amazes me when people bring it up in conversation that their company is going to build a cloud to better meet the needs of its users and customers. The only thing that amazes me more is the number of people I have talked to who believe that because they have a few hypervisors with virtual machines, they have a cloud.
