The nature of public safety applications is such that the advantages of shared systems are greater in both cost and utility. Public safety applications are increasingly interconnected to inter-agency, regional, state, and national systems and databases.

As new data sources and applications become available, the cloud model makes it possible to amortize the investment required (to make third-party plug-in services available to users) over the entire user population. With lower integration costs come greater incentives for the creation of new, innovative technologies. As the cost-benefi t of supporting third party services is enhanced by lower up-front costs, support for the add-on marketplace becomes a competitive advantage. Here is a complete report
