21 Service Models Software as a service (SaaS) Platform as a service (PaaS)Infrastructure as a service (IaaS)
23 Software as a service (SaaS) Web-based, on-demand distribution modelSoftware is hosted and updated at a central site and does not reside on client computers/servers.SaaS applications are hosted and run by service providers, saving the end user the upfront investment in software purchases and the ongoing upkeep and maintenance.
24 Software as a service (SaaS) Commercial Software Web access to commercial software Software is managed from a central location Software delivered in a “one to many” modelUsers not required to handle software upgrades and patches Application Programming Interfaces (APIs) allow for integration between different pieces of software
25 SaaS CostsSaaS services could be FREE or billed through subscriptions or usage licenses.Businesses use a pay-as-you-go method (typically monthly) for SaaS applications allowing them to save their capital for core business functions.Free when there is opportunity to generate revenue from streams other than the user, such as from advertisement or user list sales

27 Installation Ease and Low Maintenance SaaS BenefitsServer applications are hosted in a highly-available datacenter, minimizing the effects of power outages and Internet outages from incidents that affect local offices.UptimeInstallation Ease and Low MaintenanceUpgrades and patches to latest versions take little time and reduce resource requirements.Access AnywhereCustomers can connect to their applications anywhere with internet connection.
28 Where SaaS Makes Sense“Vanilla” offerings where the solution is largely undifferentiated. A good example of a vanilla offering would include where many times competitors use the same software precisely because this fundamental technology is a requirement for doing business, but does not itself confer an competitive advantageApplications where there is significant interplay between the organization and the outside world. For example, newsletter campaign software Applications that have a significant need for web or mobile access. An example would be mobile sales management software Software that is only to be used for a short term need. An example would be collaboration software for a specific project Software where demand spikes significantly, for example tax or billing software used once a month
29 Where SaaS May Not be the Best Option Applications where extremely fast processing of real time data is required Applications where legislation or other regulation does not permit data being hosted externally Applications where an existing on-premise solution fulfills all of the organization’s needsWhere SaaS May Not be the Best Option
