Cloud computing is really about economies of scale. When you run a massive data centre, not only do you get a better deal buying hardware than smaller businesses buying a handful or servers, you can also invest in automated management, videographers and failover services.
That means cloud isn't just about offering new services like Salesforce.com's online CRM system; a cloud service can offer the same services a business could run in house, like Exchange or SharePoint, but more cost effectively.
The administrators running a cloud service have the expertise to look after the systems they're running for you; they're the ones patching the servers and running the updates and keeping the lights on. That means you can get on with the IT innovation that adds value to your business.
The other advantage is that you can get a cloud service up and running much faster than you could order, set up and deploy your own hardware and software. As long as the service and SLA do what your business needs, you can get a faster return on investment from picking the cloud option. You can scale up', getting more capacity when you need it; and (again, assuming the pricing is set up to allow this) you can scale back down after your busy period when you stop using it, you stop paying for it.
Cloud services have been successful for storage, for hosted services, for applications, but cloud can also work for desktop management. As workers become more mobile, VDI makes more sense; not only does it simplify deploying a desktop system to end users, it also makes it easier to secure both the systems and the data that users are working with. If a desktop PC fails, the user can get access to their virtual system on another PC faster than you can deploy with anything but the most automated systems.
Virtual desktops aren't a new idea. We've been able to offer managed and remote desktop access with Terminal Server for years, but that still means provisioning and managing the servers and packaging and streaming the applications. While there are VDI solutions from all the major players, they're still complex to set up in the first place.
With a cloud service like ThinkGrid you get the advantages of VDI and the convenience of a cloud service. You're paying a monthly fee (49 per user or 490 for a year) that includes Windows XP desktops and Microsoft Office 2007. ThinkGrid also offers hosted Exchange 2007 and SharePoint, or you can integrate the hosted desktops with your existing Active Directory infrastructure. Users can access files on the local machine, your own file servers, file servers hosted by ThinkGrid or shared on ThinkGrid's cloud storage service.
It's a flexible mix; here's how it works in action.
