Whether you’re a founder thinking about using third party software for your start-up, or thinking about how best to structure licenses to your software, it’s important to consider how “Software as a Service” or “SaaS” licenses differ from traditional software licenses and understand the legal issues related to using them.
This report will help you understand the salient features of both the models.
Traditional software Licenses
In this model the vendor permits the organisation to use a copy of their software on your servers and systems.
This means the the client or the organisation must have a large initial capital outlay to “purchase” the license.
• The software has to be tested and certified to operate on various platforms.
• Updates and maintenance require a planned, structured and multiple stakeholders to be involved.    Massive backup and precautions are a must. Plus upgrade cost is on the client.
On Cloud
Everyone is talking about cloud now days
It enables browser-based delivery, developers realized that providing applications as a “hosted” software service (known as “Software as a Service” or “SaaS”) is a more efficient approach because :
• Customer doesn’t need to do capital investment for purchase of license and server. They essentially    subscribe for the service.
• The client only pays for the number of employees on the roll. So no wastage of unused capacity.
• The developers can provide bug fixes and updates to all the licensees at once.
• You can work on your regular platforms. No need to install new systems and platforms. Which mean    no extra installation costs? No learning curve.
• Auto updates & upgrades
• NO Annual Maintenance cost
• Green Environment
• Guarantee of quality of service, as it is linked to payments to the SaaS provider.
• Why own an item, which has no appreciation value
