Rewatching Computer Chronicles: Everything Old Is New Again

DataCenterVirtualizationIt has been thirty-one years since the first Computer Chronicles show, and that first show depicted many interesting things that were not considered new at the time. Today, we find them new and interesting, or more to the point, improved such that they are usable in ways only dreamed of then. Computer Chronicles discussed touchscreens, the importance of software over hardware, and telcos as a major source of networking. Today, we have touchscreens on EUC devices, hypervisors, and high-speed bandwidth. I wonder, would the producers of Computer Chronicles consider what we are doing today new, or just improvements on the technology of the 1970s and early ’80s?

Cloud Dependency: The Honeymoon Is Over

CloudComputingWhen you try out a new technology, there is a honeymoon period. The new technology can do no wrong, or at least it is working as you desire for the moment. Yet even if it is working as you desire, how do you know that a new cloud offering will grow with your business? Do you have the proper people managing those relationships? Have your compliance and other documents been updated to reflect that clouds are in use? Who is ultimately responsible? Continue reading Cloud Dependency: The Honeymoon Is Over

Cloud Dependency: Adoption

CloudComputingWe have spoken about other cloud dependencies: visibility, upgrades, and networking. Now we need to talk about adoption. Not the techniques, but how you move forward. What is this change in your work life now that you are using a cloud? Why is this a change in dependency? You now have instant responsibility for things outside your control: you have new people working with you, and there is now a new way of doing things. Continue reading Cloud Dependency: Adoption

Cloud Dependency: Visibility

CloudComputingWe have looked at the hidden dependencies around upgrades (Cloud Dependency: Automated Upgrades) as well as the hidden dependencies around networking (Cloud Dependency: Ubiquitous Networking). Now, we will look at the hidden dependencies on visibility. Or more to the point, the lack of visibility within the cloud. With regard to visibility, the question most often asked is, “Do we know what is happening behind the scenes within our tenancy?” Continue reading Cloud Dependency: Visibility

Virtualizing the Last Mile

DataCenterVirtualizationThe last mile of virtualization has multiple dimensions, based on where you are going with virtualization. When you ask about the last mile of virtualization—about what it will take to get to 100% virtualized either within your data center or within a cloud (hybrid, public, or private)—the “it depends” answer is the one you will get most often. So, what will it take to get to 100% virtualized?  Continue reading Virtualizing the Last Mile

Cloud Dependency: Automated Upgrades

CloudComputingIn my last cloud dependency article, I reviewed the need for ubiquitous networking. In this article, I look at the need for automated upgrades. I do not mean the need for automation in general, but specifically the need to automate any upgrade or update behavior. There are two sides to every cloud story: what the tenant does and what the cloud service provider does. In both of these stories, there is a need for well-planned, automated upgrades. Also needed is very good documentation on how to upgrade if the automation fails or if there is no easy way to automate. Upgrades should be bulletproof. We trust, but verify.  Continue reading Cloud Dependency: Automated Upgrades
