Take the time to talk through traditional datacenter management. All companies have some form of a datacenter or server room (or desk in break room - ). In these datacenters, all the server hardware, networking equipment, storage, HVAC, power, etc. reside. The network admins manage the physical hardware and the operating systems and applications.For some work loads, companies found it more cost effective to go with a hoster who owns all the hardware associated with a datacenter and just rent computing, storage and networking. A great example is web hosting.There are times where the company wants to own the server hardware, but they don’t want to manage network pipes and HVAC needs in their own facilities for certain work loads so they go to a hoster and rent space to hold their physical servers.. This is the colo scenario.
Since everyone in the world seems to be using “cloud” in their products, let’s take time to really break down what “cloud” really is. I like to look at cloud computing as a methodology. If you look at the methodology, there are some key characteristics that you need to look for. The five items in the slide are from the NIST definition which I like.Take time to discuss each one and why they are important.
Now that we have looked at what really makes up a cloud computing methodology, let’s look at the three most common types of clouds that people refer to. The first is the public cloud. This has been around since Al Gore invented it back in the 1990’s – commonly referred to as the Internet. Seriously though, the public cloud is essentially infrastructure that you don’t own, but you take advantage of the resources. Think hoster from the old days. What are resources you used back in the 1990’s where you didn’t own the infrastructure? Maybe it was free or was for a charge. [aol, compuserve, hotmail, yahoo, messenger, google, etc.] Today, this has blossomed like you wouldn’t believe. Netflix, youtube, etc. The next is the private cloud. This involves taking the infrastructure you own in our own datacenter / server rooms and applying cloud computing methodologies to get greater effeciencies and scalability. This requires automation, workflow, self service capabilities, etc. Just having your own infrastructure in your own facilities does not automatically equate to a private cloud. Having a file server with Exchange servers for email does not mean you have a private cloud.Really take the time to drive this home.Hybrid cloud is combining the power and benefit of both a private and public cloud to take advantage of each in a symbiotic manner.

The story so farThe cloud.. Is a service-based approach Has specific characteristics (On-demand, ubiquitous, elastic, location independent, measured) Has various options for how it’s delivered (delivery methods) and how responsibilities are separated (IaaS, PaaS, SaaS) Ultimately means IT transformation
