Is cloud computing revolving back to Grid Computing?

A couple weeks ago I was at Sydney Google offices attending the Sydney CloudCamp and while there I attended the Cloud & Application scalability session. It was a very good session.

CloudCamp is by nature an unconference and there are no specific subjects to discuss, no key notes and no presenters. The attendees are part of the discussion and are responsible for deciding the themes to be discussed.

In this specific session I brought up a topic related to scalabity of applications in cloud enabled environments when applications require more resources from Utility Computing than a single host is able to provide. All attendees agreed that there is necessity to re-design applications if more resources than what a single host can provide is required. I understand that in most cases it is possible to ramp up host resources in a way that even the most demanding applications would be fulfilled, either adding memory, I/O or processors.

Some advancement suggests that soon applications will be able to share CPU and memory resources from different hosts in the cloud. However what is the real scalability of the cloud then? This brings the question – Is cloud computing revolving back to Grid Computing? Haven’t we been there already a decade ago?

Learning Path to VCP4

I am on my learning path to VCP4 and should soon seat for exam as Vue has released the exam to general public about a week ago. Of course I have been using VSpehere in my labs but I also have been running it in production environment. VSphere4 so far proved to be a steady product with few minor bugs to be fixed during the next minor releases. In my opinion one of the biggest drawbacks however is the incompativility with VMware’s VDI (VMware View) framework and other products. VMware is promissing to fix this yet this year, tho.

During my studies I found few diferent learning sources and posts and I would like to recomend the following:

The ultimate vSphere4 learning path: Videos, Webcasts, Podcasts, Free online classes and much more| The deep core of the phenomena.| HyperViZor by Hany Michael
VCP4 Resource Page by bunchc (??)
Lastly, Scott Lowe’s (@scott_lowe)new Mastering VMware vSphere 4 that can be purchased from Mastering VMware vSphere

Blog Introduction

After 3 full years involved with virtualisation and cloud computing I have decided to setup my own blog to share ideas, technical discussions and information. There is big virtualisation hype at the moment and the products, concepts and technologies are quickly maturing and reaching large organizations. Concepts like VDI are promising to change the way organizations manage and deliver their desktops while allowing them to reduce management footprint. These framework changes will also affect the IT resourcing industry and will shape the profile of the IT professionals for the next five year. There is a lot to talk about and that is why we are here.
