When we think about network connections, our focus is usually on bandwidth. Bandwidth is the main metric in everyday use, as most connections are within a local site, where latency will be very low. There are a few specific instances in which this is not true and latency is the main target. High-performance computing (HPC) is one, …

Getting to OpenStack
In the industry, OpenStack is seen as very hard to implement. Considering this, I began to think that most people who deploy OpenStack try to bite off too a large chunk of OpenStack at one go, to implement it all instead of just what they need.

Hoping for a More Open VMware

Vendor each believe that their solution is the best. They feel that integrating with competing solutions is unnecessary. Oracle and Microsoft were the most well-known examples, happily attracting users with a locked-in …

Hyperconvergence and OS
In the good old days (rose-tinted spectacles required), there was only one operating system in the stack. It took care of device drivers and file IO. There were many flavours of OS, depending on the period, from UNIX and Windows to OS/2 and MacOS, and many, many others. Over time, the selection of operating systems in the data center reduced …
Automation, Orchestration, and DevOps in Today’s Data Center
Automation and orchestration are two of the terms that you hear about more and more especially when discussing virtualization and or cloud computing. One of the main reason for that is as virtualization and cloud computing technology continues to mature, so has the automation and the orchestration that are such an intricate part of the solutions presented forth from this technology and as such there are more and more products and services that are built around automation and orchestration itself. For this post, I want to focus more on the underlying technology before I get more into the different products themselves. This may be most interesting for anyone that is looking to expand their skillset to be able to compete and excel in a technology world that is traveling full speed up into the clouds.
