This presentation is for Gartner Symposium 2011 in Barcelona. Audience is IT managers and the focus is on highlighting the challenges of ICT
The three parts of the presentation are some background on how cloud computing will impact existing IT infrastructures, how different kinds of applications have an impact on the infrastructure and then how all this comes together.
The first of these is “virtualization”, which is the ability of a single physical server to do the work which was previously done by many servers. This is an example from Huawei’s own implementation for desktop consolidation and you can easily see the substantial benefits in terms of CAPEX and OPEX. Virtualization is all about efficiency and reducing costs.
First, let’s talk about Cloud Computing. It is a very confusing area and this fictional book title shows how a Google search would return a million different definitions from some of the smartest people in IT. I’m not going to give you a different definition to add to the confusion, but I want to focus on a couple of key issues related to Cloud Computing.
And the explosion of social networking on the Internet will also drive local versions and even enterprise versions of these types of applications. They need lots of storage for videos, pictures and graphics and also can use a lot of processing when key events occur.
But that is not the most important part of Cloud Computing. Easily as important are “flexibility” and “responsiveness”. With the proper cloud infrastructure, you can re-use the physical server resources based on the overall need, using them during the day for desktop virtualization and at night for product testing – this is something we do within Huawei. This flexibility can actually be every few minutes, not just at different times of day. Responsiveness is about the ability to change the way that business is conducted in IT. Previously, if you needed a new server for a new application, you had to go through a long purchasing process and wait for installation. With the right cloud infrastructure, this time can be collapsed to a few minutes, which can have a dramatic impact on new product development times, as shown in these two examples.
<Note clicks><First>In my view, achieving the right infrastructure foundation must be:scalable and reliable, have support for ICT and be open. I’ll summarize these as:<click> Providing “digital dial tone”. By this, I mean the type of reliability that is just like dial tone – you take it for granted, it is just always there.<click> Support “all media”. More and more traffic and work in the IT environment includes video and other types of rich media. This means that the cloud infrastructure must be structured to support these media or you will run into problems in the future.<click> The last characteristic, of being “open” is really about having options for the future. If the cloud infrastructure is open, you will have a much better chance of being able to support whatever comes up in future applications.
One way to ensure that you have a reliable and scalable architecture is to make sure that it can scale to a large size and be physically distributed. This provides needed flexibility and both reliability and resilience.
To ensure support for all media, look at the types of applications that need to be supported, the way that this will converge for users and for the types of devices that will require support.
<NOTE clicks><First> Of course, any cloud infrastructure requires a solid foundation, including the physical data center, the hardware that runs the cloud and the critically important software that makes the cloud work.<click> But it also must have open interfaces to support all types of applications and the tools that will be needed to support all types of development in the cloud. At the present time, there are not formal standards for these interfaces, but the de facto standards provided by Amazon Web Services, which are shown here, are a good basis.<click> And don’t forget all of the management, provisioning, billing and other services that are required. You need to make sure that you have open interfaces, preferably built on web standards, so that these can be integrated with existing systems and evolve as needed.
<NOTE clicks><First> As we have seen, there are many types of information that are converging in the IT and Communications worlds and they all need a unified infrastructure.<click> The best way to support that need is with a cloud
On top of having that cloud infrastructure, you also need tools to manage the cloud, build and deploy applications on the cloud and you also want to be able to take advantage of the wealth of applications which are already being deployed on clouds.
