Software as a Service Definition

With SaaS, the customer can make use of software products by subscribing to them online. The application itself, including its code, servers, and database, is maintained by software providers like Amazon Web Services or Google Cloud. Users can access the software simply through a web browser or mobile app.

How does Software as a Service actually work?

There are two steps involved: first, the vendor develops the software; second, customers use the software.

The vendor creates software to meet business needs or challenges. They usually gather requirements from customers and aim to solve problems faced by multiple users simultaneously.

Customers pay for the product over time with a subscription, expecting that their feedback will be implemented. It is important to note that customers do not own the software itself but benefit from not having to worry about its maintenance.

Core Benefit of Software as a Service

The primary benefit of Software as a Service is that it provides an alternative to traditional software installation, which typically involves configuring a server, installing the program, and setting it up at the customer''s site. SaaS products, on the other hand, are housed in a cloud network, accessible via the Internet or an API.

Unlike traditional models, SaaS products come preconfigured, eliminating the need for on-site installation and configuration.

Advantages of Software as a Service

• Installation costs are significantly reduced, as SaaS installations are completed in just a few clicks.
• Time to start using the software is reduced, as there is no need for server setup.
• Maintenance and updates are cheaper, as the vendor handles these tasks and applies changes globally.
• SaaS provides scalability and integration, with vendors like AWS ensuring minimal interruptions during usage spikes.

Challenges of Software as a Service

• Consideration prior to commitment: Evaluate customer support and data security before committing to a SaaS provider.
• No control and SLA arrangements: Once using SaaS, you have no control over programming and must rely on the vendor for repairs, as specified in the SLA.
• Problems with software integration: Dependency on the vendor''s support team can impact your reputation, especially if software downtime affects clients.

Key Characteristics of Software as a Service

• Accessibility: SaaS applications should be globally accessible and available 24/7.
• Multi-occupancy model: Services are provided to multiple users through a shared software system.
• Security: Encrypted storage must be provided to protect user data, with restricted access.
• Scalable Architecture: Infrastructure must be able to scale up or down based on resource needs.
• Single Sign-On: Users should be able to authenticate and access the service using a single set of credentials.
