A specialized software provider can target global markets: A company that made software for human resource management at boutique hotels might once have had a hard time finding enough of a market to sell its applications. But a hosted application can instantly reach the entire market, making specialization within a vertical not only possible, but preferable. This in turn means that SaaS providers can often deliver products that meet their markets’ needs more closely than traditional “shrinkwrap” vendors could.
Web systems are reliable enough: Despite sporadic outages and slow-downs, most people are willing to use the public Internet, the Hypertext Transfer Protocol and the TCP/IP stack to deliver business functions to end users.
Security is sufficiently well trusted and transparent: With the broad adoption of SSL, organizations have a way of reaching their applications without the complexity and burden of end-user configurations or VPNs.
Availability of enablement technology: According to IDC, organizations developing enablement technology that allow other vendors to quickly build SaaS applications will be important in driving adoption. Because of SaaS' relative infancy, many companies have either built enablement tools or platforms or are in the process of engineering enablement tools or platforms. A Saugatuck study shows that the industry will most likely converge to three or four enablers that will act as SaaS Integration Platforms (SIPs).
Wide Area Network's bandwidth has grown drastically following Moore's Law (more than 100% increase each 24 months) and is about to reach slow local networks bandwidths. Added to network quality of service improvement this has driven people and companies to trustfully access remote locations and applications with low latencies and acceptable speeds.
