SaaS Comparison

Today, more software companies are emerging with On-Demand (also known as SaaS) versions of business solutions that were traditionally delivered as installed products. However, transitioning to a SaaS model is not as simple as merely repacking an enterprise product. Several unique challenges must first be overcome, including:

Integration with Back Office Applications: SaaS solutions need to integrate with back office systems to avoid duplication of work and create consistency of data across systems. This is quite challenging because back office systems are typically behind corporate firewalls and may expose only proprietary protocols. Integration plans also need to consider the fact that networks or systems may occasionally not be available.

Multiple Client Support: SaaS solutions should have the ability to support multiple clients from a single instance to reduce infrastructure, hosting and management costs.

Performance: SaaS solutions should have the ability to support many users with minimal resources to derive efficiencies and economies of scale.

Security: Hosted applications have specific security challenges because they are often publicly accessible and have a much higher risk of data theft than installed applications. In addition, a multi-tenant architecture creates additional risk since a customer may have access to another customer’s data.

Response Time: Sub-second response time is a requirement for most SaaS applications because Internet users expect pages to load immediately.

Shorter Release Cycles and Ability to Enhance Features: SaaS companies are expected to add innovative features almost continuously since this is a key advantage that SaaS solutions typically offer over traditional installed software.

Usability: Today’s web applications are expected to be as interactive as typical thick client applications. Technologies such as AJAX have become extremely important in this context.

Multi-Browser Compatibility: Since every company has its own standard for supported browsers and operating systems, it is extremely important that SaaS solutions comply with multiple browser platforms and versions.

Manageability: A hosted application requires an infrastructure to support billing, logging and provisioning across multiple customers.

Availability: Continuous, 24/7 application availability requires an investment in the solution’s infrastructure, processes and people.
