Cloud Computing• Infrastructure as a Service
– Compute Nodes– Storage– Present resources as infinite
• Advantages– No capitalization of compute infrastructure– No operations of compute infrastructure– Very useful in development phase and during peak load– Easy to use, proven, quick turn around
• Disadvantages– Higher costs during the operations phase– Reduced control of data, location, authority, security etc.
• Existing Clouds– Commercial clouds: “Pay per use” and “allocation” model– Examples: Amazon EC2/EBS, Microsoft Azure, Google
AppEngine etc.
The Problem
• Each modeler has separate collection of scripts and procedures which are typically ad hoc, brittle and hard to maintain.– NCEP NAM: NOMADS/OPeNDAP

Community Involvement• Feedback on this plan• Other data streams we should handle
immediately?• Plan to brief NFRA Modeling Committee
regularly• Wilkin (MARCOOS) has been identified as
an ideal end-user modeler for participation (tech savvy, heavy data assimilation)
• We would like to add two others. Volunteers?
