IMS and Cloud Computing<br />
By Trevor Eddolls With Micros<strong>of</strong>t now involved in cloud computing,<br />
via Office Web Apps and Facebook integration, and<br />
Google working with <strong>VM</strong>ware to develop a new operating system<br />
for the cloud, you may wonder where the mainframe fits<br />
into this exciting new world. You might also be curious about<br />
the role <strong>of</strong> <strong>IBM</strong>’s venerable Information Management System<br />
(IMS). Well, that’s what we’re going to explore. According<br />
to Wikipedia, “Cloud computing is Internet-based computing,<br />
whereby shared resources, s<strong>of</strong>tware, and information are provided<br />
to computers and other devices on-demand, like the<br />
electricity grid.” Wikipedia further suggests that: “Cloud computing<br />
describes a new supplement, consumption, and delivery<br />
model for IT services based on the Internet, and it<br />
typically involves the provision <strong>of</strong> dynamically scalable and<br />
<strong>of</strong>ten virtualized resources as a service over the Internet.”<br />
So, you can look at cloud computing as a way <strong>of</strong> delivering<br />
hosted services over the Internet. The accompanying sidebar,<br />
“Cloud Computing Origins and Evolution,” <strong>of</strong>fers further insight<br />
on the types <strong>of</strong> cloud computing that have emerged, but again,<br />
our focus is on how <strong>IBM</strong> and IMS support the concept. ><br />
