Is the cloud too much of a good thing? Virtualization and Cloud Computing have been one of the biggest technological advancements of the twenty first century and it continues to grow at an amazing pace. Cloud computing has started to obtain mass appeal in corporate data centers as it enables the data center to operate like the Internet through the process of enabling computing resources to be accessed and shared as virtual resources in a scalable manner. Each day there seems to be a new announcement or press release about a new product or service that has been released utilizing some form of cloud computing and I do not see this trend changing anytime soon.

CERN goes Hybrid: Have you heard the news that CERN is going to the cloud? The term CERN is used to refer to the European laboratory located in the northwest suburbs of Geneva snug on the Switzerland border. The main function is to provide the particle accelerators, as well the other part of the laboratory infrastructure needed to perform high energy physics research. CERN was originally established in 1954 as The European Organization for Nuclear Research. The research at the facility has moved past nuclear research and has fully expanded into one of the largest laboratories for particle physics research using the Large Hadron Collider. On an interesting side note, the main site at CERN is also the birthplace of the World Wide Web and, historically before that, these facilities were a major wide area networking hub for sharing the scientists research with different scientists located elsewhere.

What happened to Software Defined Networking? A while back I wrote a post where I thought 2012 would be the year for Software Defined Network (SDN) and I am really surprised that this technology has not gained greater ground. Now that we are half way through 2013, I find myself still waiting for the adoption of this technology to really take off. With investments from companies like Cisco, IBM, Alcatel, Juniper Networks, Broadcom, Citrix, Dell, Google, HP, Intel, NEC, and Verizon which all have current SDN initiatives, SDN will assume a role in IT infrastructure at some point. It just seems like it is going to take a little while longer to catch on.

A look at Network Automations Automate 9: Last month I wrote a post titled “Is Automation Killing the Engineering?” For this post I want to explore the idea that it is not the automation that might be killing the engineering but rather how far and good some of the 3rd party application are in pretty much doing the work for you. One prime example of that concept is Network Automations’ AutoMate 9.

There are different public cloud use cases. Here at The Virtualization Practice we moved our datacenter from the north to the south part of the country and utilized the cloud to host the workloads during the transition. Edward Haletky, yesterday posted about Evaluating the Cloud: Keeping your Cloud Presence and presented the question and his thoughts of is it worth staying in the cloud or bringing the data home.

My thoughts on the VMware vCloud Hybrid Service: There was an announcement made last week about the new VMware vCloud Hybrid Service which will bring VMware Public Cloud Service to the masses later this year. There are a couple of posts from our own Virtualization Practice analysts which can be found here and here. Since there has been plenty of conversation about just what the vCloud Hybrid Service is, I am going to use this post to share my thoughts on the service itself.

Is automation killing the engineering? When MTV first appeared on air, the first video it played was, “Video Killed the Radio Star.” Fast forward a few decades and I have to wonder if automation is killing the engineering. In the early days of virtualization the administrators were expected to be proficient via the command line and to be honest if you wanted to really understand how things worked, command line administration was an absolute must have skill. Virtualization has evolved from those early days with more and more features and services getting added to the infrastructure that the need for the vast command line skills seem to be fading as the technology continues to mature. Looking forward where cloud computing is working to achieve complete and total automation, I have to wonder how administrators will handle the stress of getting issues resolved when automation is not an option.

What is the future of virtual storage in a Software Defined Data Center (SDDC)? As more and more technology gets moved from hardware to software in the SDDC, I have to wonder which direction virtual storage will go.

If we use networking as an example, the technology has evolved from setting up local virtual switches on each of the hosts to a virtual distributed switch (VDS) model where all the individual host-level virtual switches are abstracted into a single large VDS that spans multiple hosts at the Datacenter level. In this design, the data plane remains local to each VDS, but the management plane is centralized with VMware vCenter Server acting as the control point for all configured VDS instances.
