We all need performance and capacity management tools to fine tune our virtual and cloud environments, but we need them to do more than just tell us there may be problems. Instead, we need them to find root causes for problems, whether those problems are related to code, infrastructure, or security. The new brand of applications, if designed for the cloud à la Netflix, or older technologies instantiated within the cloud need more in order to tell us about their health. Into this breach comes a new set of tools, as well as an existing set of tools.
The latest and greatest thing in the data center is apparently containers. For those of us with long enough teeth to remember the heady days of the early millennium, they look and smell a lot like Solaris Zones.
Containers in their current incarnations are garnering a great deal of attention, especially in the DevOps world, where continuous deployment is the latest word in deployment strategies.
It is said that nothing is new in the world, and with containers, this statement could not be truer. I think, therefore, that an overview of the evolution of the container may be useful.
As technologists and analysts for the virtualization and cloud spaces, we are always talking about various places within the IT stack. Actually, as we talked about within the article Technical Arc of Virtualization, we have noticed that many people are moving up the IT stack, forming new and more interesting substrates of IT. These substrates are used to simplify the actions one takes to deploy new and more interesting applications, while at the same time abstracting away the physical and virtual layers of the stack—in essence, forming new substrates on top of which to build.

On the 29th of July, Microsoft released to the world the latest iteration of its highly popular desktop operating system. Well, I say “popular” because in over 80% of all desktops and notebooks it is the desktop operating system of choice. However, “choice” may be too strong a word, as the OS comes with the hardware, so perhaps “Hobson’s Choice” would be a better phrase.
In previous articles, we discussed IT transformation in general, IT transformation and security, and the top-down and migration approaches to IT transformation. Now, it is time to discuss a method of IT transformation I call “no changes to management.” With this method, IT transformation happens by natural, existing means within the data center, by adding software to aid and augment existing management software. That software forms the core of a transformation engine that, in effect, migrates and manages your cloud presence from your on-premises existing management suite.
