Today the Technology Preview version (0.8) of the vCloud API was released. This opens the door to build your own cloud based upon proven VMware technology. This is the next step of VMware entering the Cloud Computing arena.
Who is the vCloud API targeted towards?
The vCloud API is targeted towards developers and IT Admins across our service provider, ISV and enterprise customer community
What are some key distinguishing characteristics of the vCloud API?
Pure virtual nature makes it very easy to use and implement
Supports the industry standard OVF 1.0 format.
It is designed to support existing customers as well as enterprise still running applications on physical hardware to move their legacy applications into the cloud.
Developing an application to the vCloud API, makes it compatible with a large number of VMware-based internal clouds or external service provider clouds à broad application compatibility and choice of SPs (no lock in)
This API opens the cloud to application vendors, service providers and enterprise IT. Simplifying the way applications are deployed and managed within the cloud.
Well it’s going to be big (and is already being hyped as such). It’ll be a paradigm shift in the world of IT as we know it. But as I explained in an earlier post: we still have a long way to go before it’ll be mainstream. Cloud Computing is the come together of multiple technologies that already exist. It can be compared to a chemical reaction : Every component is there, we are now in the process to evolve to a new level in IT.
Defining Cloud Computing seems to be something that nobody can agree upon. Here goes mine:
Cloud Computing is an IT model which allows business to scale IT capabilities in such a way that it suits the needs at any time. This can be realized real-time through on-demand self-service. It will be delivered as-a-service anytime, anywhere and will be paid per use afterwards.
Such a definition can be broken down into 4 characteristics that build up Cloud Computing:
Elastic & dynamic infrastructure; The infrastructure on which Cloud Computing is build should be able to handle the ever changing demand from business. In such in needs to be elastic and dynamic to supply this demand. Virtualization is the method to provide this flexibility.
On-demand self service; Business needs to have the ability to self service their needs real-time. Controls should be provided that service this need without the help of external parties.
Location independent; End-users should be able to access the service anytime, anywhere. Internet is the highway that will connect the service to standard input devices.
Pay per use; A consumption model must be in place where one pays for the services that have been provided to them. No more, no less. Just the capacity that has be used should be billed afterwards.
For more information look at the following information sources :
As we all have noticed Cloud Computing has become the next best thing that has hit IT in a long time. Every company all of a sudden has a product that is “in the cloud”. It’s good to see that a lot of companies are boarding the train, but it also results in confusion and a feeling that is “it’s just to good to be true”.
This can also be seen in Gartner Hype Cycle for Cloud Computing. Cloud Computing is currently at the top op the so called “Peak of Inflated Expectations”. It has been hyped by the IT industry and is indeed generating a lot of expectations. As Gartner predicts this will eventually result in “disillusionment”. Thinking that it’s just one of those “IT things” that will eventually fade away and be replaced by another big hype.
It will however become mainstream in next 2 to 5 years. Evolving into mature business model for provisioning IT services. The “fog” surrounding Cloud Computing will eventually clear the sky. Till that time follow the next simple rules:
Proceed with caution; Don’t believe everything that is said / written about Cloud Computing. There is a lot of rubbish out there. Rational thinking is the key.
Inform yourself; Knowledge is power! Gather as much information as possible about the subject. But again Proceed with Caution!
Fit it into your strategy; No rush! But Cloud Computing should eventually fit into your IT strategy. Keep it in mind making future decisions.
Your not the only one; There are more people / companies out there dealing with the same “cloud”. Talking amongst peers helps a lot in generating your own vision regarding “cloud computing”.
