Cloud Computing Addresses Two Wholly Different Market Needs
IT organizations need to focus their efforts on the specific facet of cloud computing that applies to a given project

One of the fun aspects of a nascent cloud computing market is that there are "veins" of innovative thinking to be mined from all of the hype. Each of us discover these independently, though the velocity of recognition increases greatly as the effects of "asymmetrical follow" patterns take effect. Those "really big ideas" of cloud computing usually start as a great observation by one or a few independent bloggers. If you are observant, and pay attention to patterns in terminology and concepts, you can get a jump on the opportunities and intellectual advances triggered by a new "really big idea".
"Cloud computing is a confusing topic for vendor strategists. One reason? Most of us confuse two fundamentally different types of compute clouds as one. Server clouds support the needs of traditional business apps while scale-out clouds are designed for massive, many-machine workloads such as Web sites or grid compute applications. Scale-out clouds differ from server clouds in five key ways: 1) much larger workloads; 2) loosely coupled software architecture; 3) fault tolerance in software, not hardware; 4) simple state management; and 5) server virtualization is for provisioning flexibility — not machine sharing. Strategists must update their server virtualization plans to embrace the evolution to server cloud, while developing a separate strategy to compete in the arena for scale-out clouds."
Get it? There are two plans of attack for an enterprise looking to leverage the cloud:
Around then I started seeing references to other posts that suggested the same thing; that there are two customers for the cloud: those that need to achieve higher scale at lower costs than possible before, and those that want to eliminate data center capital in favor of a "pay-as-you-go" model.
The point here, I guess, is that comparisons between Scale-out and Enterprise clouds, while sometimes tempting (especially in the Google vs. Microsoft case), are rather useless. They serve different purposes, often for completely different audiences, and enterprise IT organizations would do better to focus their efforts on the specific facet of cloud computing that applies to a given project. If you are a budding PaaS vendor, understand the distinction, and focus on the technologies required to meet your market's demand. Don't try to be "all cloud to all people".
