HP Virtualization VMWare

http://www.vmware.com/a/vmmark/ – Impressive Benchmarks by HP

Personally, I love seeing stuff and tests like these.

Whilst other technologist’s from representing companies may be quick to defend why their particular company’s hardware doesn’t get the top score they would of hoped. I try to take another angle on approaching these sort of benchmarks.

Why? I’ll break down the reasons why I think these are good to have.

Competitive – Simply, without some form of benchmark or competitor to design your products to compete with – Then technology wouldnt get as sophisticated as it has. Whilst server virtualization hasn’t been as prevalent or utilised as much as it is over the recent years. This particular benchmarking results show there are some worthy competitors to HP in the server market. It wouldn’t be as fun if it was a one horse race. This keeps the engineering team from Fujitsu, Dell, HP etc returning to the drawing board to make servers better and better.

And for a virtualization geek, this is exciting.

Trending – We can see how well servers do now and compare in five years time, There may be a gradual improvement in scores in the five years, or they may just increase exponentially.

Reviews – Simply put, some-one looking to buy a server for virtualization purposes has a great source of information on best performing models as a starting point to purchasing the right server. It also provides the consumer with an idea of just what elements affect server performance.

Well done to the top four server vendors – Fujitsu, Dell, HP and Cisco


Cloud Computing – My own definition.

This will no doubt be tweaked over the years to come, but I thought I would share my own personal definition of what the concept of cloud computing is today.

“Cloud Computing refers to a virtual shared IT infrastructure where resources are provisioned as required from a shared pool of computer, storage and network on a pay per use basis via the Internet or WAN.”

Alternatively Wikipedia offers the following definition (Retrieved 5th August 2011 from (http://en.wikipedia.org/wiki/Cloud_computing)  “Cloud computing refers to the logical computational resources (data, software) accessible via a computer network (through WAN or Internet etc.), rather than from a local computer.”

My employer HP define it as “a delivery model for technology-enabled services that provides on-demand access to an elastic pool of shared computing assets.” from Finding the right cloud solutions for your organization,

Gartner defines cloud computing as a style of computing where scalable and elastic IT-related capabilities are provided as a service to customers using Internet technologies (Retrieved August 8th 2011 from http://www.gartner.com/technology/research/cloud-computing/).

So lets dissect these and dig out the common denominator between the three different definitions. The common theme or series of words are

“Shared, Instant, scalable and accessible”.

Behind all these definitions, you’ll see a lot of supporting detail that give a broader understanding of what the cloud really is.  I think the common themes really boil down to:

  • Instantly available – services that can be made immediately available
  • Scalability & elasticity – both are enablers of resources becoming instantly available. Without the cloud’s scalability, the whole speed aspect of the cloud goes away.
  • Shared resources – services that run within a set of shared resources – infrastructure or applications – that gain the benefit of multi-tenancy.
  • Accessibility – services that are processed over the Internet to the end user.

Private Cloud A private cloud refers to a cloud computing  environment which offers services within a single enterprise organisation and it’s firewall but may be hosted internally or externally to the organisation.

Public Cloud A public cloud refers to a cloud computing environment made available to the general public using the Internet and is external to the 0rganisation’s firewall that owns the environment

Hybrid Cloud A hybrid cloud refers to a computing environment that combines both private and public cloud computing environments.

Agree? Please comment and share your definitions, I’d love to read! There are more exciting posts to follow this one, particularly around Hybrid Cloud the many cloud offerings that HP have in this space. But for now, we’ll save it for another time
