What is Software as a Service (SaaS)?
Traditional software applications such as Microsoft Office™ are installed on your desktop computer, and they use data (documents, spreadsheets and emails) that is also stored locally. In contrast, SaaS software is installed on Internet sites and used by people through their Internet connections. Generally all that is needed to use the software is a Web browser and perhaps a small helper application called a “plug-in.” That change can dramatically lower costs, increase data sharing, and raise the level of security for critical data. It lowers costs because users don’t need powerful computer servers to run the complex programs – those are owned and operated by the software company, in this case, CrimeCog. The potential for data sharing is increased tremendously because it is stored where every authorized user can access it, regardless of where they are. And the security is high because data is not stored on personal computers or local servers. A dropped laptop or a loss of power locally
Software as a Service is more than simply software delivered over the internet by an ASP – Application Service Provider. And is certainly different from the traditional client/server model where access is gained by a program on your PC (the client) and the shared data is stored on your organisations network server (the server). SaaS providers such as NGA.NET and Salesforce.com deliver business solutions via the internet using a shared infrastructure on-demand model that by design and architecture reduces upfront costs and Total Cost of Ownership (TCO) as well as delivering increased business performance. It enables business to minimize infrastructure and maintenance costs while accessing the latest technology and business solutions with more frequent upgrades. It is also one of the fastest growing IT sectors globally.
