Why do you think executives, particularly in the Asia Pacific, are currently hesitant about adopting cloud computing services? What are their major concerns? Do you think those concerns are justified?
Some of their concerns about adopting cloud are based on the opinion that it is too early to make the move. And some of the cloud offerings arent particularly mature yet although there are some technologies like virtualisation that are pretty well proven. There are also specific concerns, such as security, which are more focused for specific offerings or specific customers.
In some cases, these concerns may slow cloud adoption and may not be in their best business interest especially where things have been proven, such as virtualisation, while in other cases, I think their concerns are very valid.
Asia Pacific is a key region for EMC as we see this part of the world as having strong potential for growth in uptake for cloud services.
Why is the current public cloud model being proposed by Google, Microsoft and Amazon not likely to be the delivery model for the next phase of corporate computing? What are the key turn off issues with the broad public cloud approach?
One of the key things that CIOs are looking for is this ability to control their environment. In many cases, they have to provide compliance statements and they have to guarantee the viability of data and services.
This idea of moving everything to an external cloud provider creates enormous fear. They dont know exactly what happens, whos going to take liability and whos going to manage the risk associated with that. There may be some services that they would be open to receiving from external cloud providers, but fundamentally, this is not the way IT will function in the future.
Hence, I believe organisations will be best served with the hybrid cloud where they may be happy to tap on a public cloud operator for some functions, and in other cases, they need to operate certain functions internally. And the best result would be some combination of the two.
What are the key arguments relating to the public cloud versus private cloud and what are the stand-out key differences between the two?
To put it simply, a public cloud is controlled by a cloud provider which enables dynamic, on-demand, self-service that is flexible and scalable. The downside is that the public cloud can compromise reliability, security and control.
The private cloud, on the other hand, is controlled by the companys IT organisation. While it also offers the benefits of a public cloud, a private cloud gives you full control of your assets, which means you have a trusted, reliable, secure and controlled environment.
