John Gannon asking me a question about “the implication of VMware acquisition of Spring Source?”
VMware: I already have the most popular virtualization software and I will integrate Spring Source and create the best PaaS offering.
Amazon EC2: I am extending my cloud facility to a virtual private environment so that you security concerns are taken care.
Microsoft: I am giving you a platform which is very similar to what you use so that you can seamlessly extend your application to the cloud and even the developers can continue to use the same set of tools.

IaaS: Infrastructure as a Service

PaaS: Platform as a Service

SaaS: Software as a Service

The proposition:

- I will give you a virtual machine in the cloud which you can provision any time you want
- You pay for what you use
- You can scale it up or down whenever you wish
- You continue to use the same set of software
|
- I will give you a software platform which you can use to build and deploy application in the cloud
- You pay based on usage
- You do not need to pay for any additional software

Questions / doubts:

- Will things work exactly the same way it works now?
- Is my data secured with you?
- What guarantees do you provide?
|
- I have to rewrite my existing applications
- I will also have to learn the new platform which is different
- I will get locked in to your platform
|
- How do you take care of my needs if it is beyond or different from what you provide?
- How do I integrate with my existing applications?

Different vendor strategy
Here is a diagram which shows the strategy of some of the major player in the Cloud Computing space to counter the questions and doubts:
SalesForce.com: I am giving you a Force.com with which you can build what you need over and above what I provide out of the box.
Google App Engine: I am creating a platform with which you get access to my complete infrastructure – practically unlimited processing power & storage and all my existing services.
What do I think?
This is my view for the longer term – 3 to 5 years.
To take full advantage of the power of cloud computing we need to break away from traditional programming paradigm – thinking bounded by …
- …sequential processing
- …relational storage
- …the physical boundary of a machine
And, I think Google App Engine is in the best position to provide solution for the new paradigm.
