Cloud Computing in IT

Eric Strause, Global Knowledge Senior Product Director for Network Technologies, presents the foundational concepts of cloud computing. In this first of a five-part series, he compares the typical IT infrastructure of applications and its corresponding network infrastructure to the more efficient infrastructure farm that is the cloud.


Hi, my name is Eric Strause, and I’m the Senior Product Director for Network Technologies here at Global Knowledge, and I’ll be talking to you today about Cloud Computing.

Today we’re going to talk about Cloud Computing in simplified terms.

So Cloud Computing is a transformation of the way IT organizations are structured. If you look at today’s world, what we have is a number of applications sitting on top of network infrastructure.

That network infrastructure consists of routing and switching solutions, server technologies, virtualization technologies and storage components.

Sitting on top of that are the applications themselves. In the way that the world is structured right now, these solutions are largely siloed so a particular application tends to have a set of infrastructure underneath it. In the challenge that’s happening today, is that right now each separate application and hardware infrastructure is only being utilized a certain percentage.

So in this instance right here, you can see this first stack for the customer relationship management application is only being utilized 50% of the time. In this next situation there’s a database that’s only being utilized 20% of the time. And so forth, we’ve got 85% utilization and 100% utilization.

The challenge that IT organizations face today is that there’s no efficient way to harness the power of underutilized assets. So in this environment, even though we’d like to get more users onto this particular set of applications up here, we don’t have an effective way to tap into the servers and the routing and switching and the storage capability that sits underneath all of this today.

What Cloud Computing brings to the table is the opportunity to really build out and separate the functions so that users are able to reach the applications through what is effectively a server farm or an infrastructure farm underneath inside a data center so that each user comes through and as they ask for an application they simply find the next available resource to be able to reach and consume that application.
