Two seemingly contradictory statements… Cloud Computing is MASSIVELY overhyped Cloud Computing will forever change the computing world todayfuture (not so distant…) … both are true, the question is “when”?

Cloud: Hype & Confusion Customer Demand Real success stories have emerged from the internet… −Google, Amazon, eBay, Yahoo, Microsoft, etc Delivering astonishing results … −Robust solutions, at enormous scale, on very low cost infrastructure The pain points around utilization, cost, and flexibility are shared by all customers… −Extremely high demand for solutions to these problems −Aggravated by current economic situation Marketing Hype Dell: Attempted to trademark “cloud computing” – denied! IBM: Suddenly everything is “cloud computing” new and old Others: Every vendor with any product that abstracts anything… Sources of Confusion New/emerging technology & terminology −W−Web2.0, Mash-Ups, Ruby, Rails, AJAX, and many many more… −I−IaaS, PaaS, SaaS, STaaS… Confusion around Internal vs. External Clouds

“A Tale of Two Clouds….” Distinguishing between two distinct phenomena … Enterprise IT Transformation (Internal Clouds) and [True] Cloud Computing

Enterprise/Large SMBs External Service Providers Primary Business Varies: Auto, Aero, Other Manufacturing, Pharmaceutical, Health Care, Retail, Entertainment, Communications, etc. Examples: GM, Boeing, Coach, Glaxo, Kaiser, Walmart, … Providing external services to consumer, SMB, or enterprise customers (for profit) over the public internet. Examples: Google, Amazon, eBay, SalesForce, Yahoo, Facebook Role of IT Business IT; basic IT functions to enable business; HR, Business process, Decision support, collaboration, etc. IT is a cost center same Business IT: Service providers have a business IT function similar to business IT for other enterprises. IT is a cost center External Service IT: Internet facing IT infrastructure optimized for massive scale at a low cost IT is core to the customers business Traditional Enterprise HPC Infrastructure; some enterprises have HPC infrastructure to do modeling and simulation for engineering, research, financial analytics, etc. also a cost center Unique to Service Providers

“Enterprise Class” IT Infrastructure/Services Service Provider = Service Consumer Delivered over an Intranet (private network) Scale = Enterprise Scale “Global Class” IT Infrastructure/Services Service Provider <> Service Consumer Delivered over the Internet (public network) Scale = Global Scale Enterprise/Large SMBs External Service ProvidersTraditional Enterprise

Conclusions The future of Enterprise IT is a hybrid environment… services sourced internally, outsourced, or from cloud service providers Cloud computing is revolutionary and will ultimately change the world…but not overnight Enterprise IT transformation is an evolutionary process that has been happening for years… There are significant barriers for creating and adopting cloud services for enterprises…
