A multi-tenant cloud-based full-function GIS

Cloud computing in itself is not sufficient be provided GIS as an on-line service at low cost to organizations ranging from individuals to thousands of users. "Multi-tenancy" is a technology that allows cloud computing resources to be shared amongst multiple organizations so as to offer full-function GIS on-line at low cost to organizations ranging from individuals to thousands of users. This presentation will cover: 1. How multi-tenancy works, and how it differs from hosting existing web/server GIS in the cloud. How it makes it possible to (1) Provide at a low cost GIS functionality equivalent to desktop GIS to organizations of scales ranging from individuals to thousands of people; and (2) Make GIS solutions instantly available "on demand" to new adopters. 2. This will have a critical business impact of this technology on GIS by dramatically lowering cost, reducing start-up time, and increasing flexibility compared with traditional GIS and with simpler cloud hosting approaches. 3. A working multi-tenant cloud-based GIS can be demonstrated, from creation of a service for a new organization, through loading data and adding users, to GIS use. Experience of deploying this technology shows new types of users starting with GIS as a Service, with high expectations of ease of use and of an instantly availability.
