Online GIS applications can be delivered using cloud computing platforms which provide Infrastructure as a Service(IaaS) resources. An introduction to essential cloud computing concepts and considerations will be reviewed in addition to a presentation of public sector industry trends involving other cloud hosted technologies related to GIS applications. The presentation will feature examples of cloud hosted GIS applications at federal, state, and local government levels including the City of Novi\'s ArcGIS Server 10 deployment using a public cloud hosting provider.

1. Exploring Cloud Computing Technologies for Geospatial Applications 2011 IMAGIN Conference DoubleTree Hotel & Conference Center Bay City, MI 3:30 – 4:15 pm Monday, May 2 nd Christopher Blough, PMP, MPA GIS Manager City of Novi Department of Information Technology

3. Gartner’s 2010 Hype Cycle: Cloud Computing

6. Service Models SaaS Software as a Service End user applications delivered as a service vs. on-premises software PaaS Platform as a Service Application platform or middleware as a service which developers build and deploy applications IaaS Infrastructure as a Service Compute, storage, and operating systems required for fundamental computing resources Increasing Service Provider Management Responsibility Increasing Tenant / Subscriber Management Responsibility

8. Examples by Service Model Software as a Service Applications (SaaS) Geospatial Apps E-mail / IM Document Management Social Media Virtual Desktops Legacy Applications Organization’s Web Site Office Software Apps Line of Business Apps Platform as a Service (PaaS) Database Testing Tools Developer Tools Database Mgt System Directory Services Infrastructure as a Service (IaaS) File Storage Systems Web Services Server Hosting Server VM Systems Virtual Servers

9. Deployment Models Private Cloud Enterprise Owned or Leased (on or off premises) Community Cloud Shared infrastructure for a specific community or industry Public Cloud Available to the general public and provides greatest economy of scale Hybrid Cloud – Composition of more than two of the above. Example: Cloud Gateways
