Software as a service definition
How does SaaS work?
SaaS operates on a cloud-based model where software applications are hosted by a service provider and accessed over the internet. Instead of purchasing and installing software on local computers or servers, customers subscribe to the software and use it online. This approach offers several advantages, including ease of access, scalability, and reduced IT infrastructure needs.
When a customer subscribes to a SaaS application, they typically log in through a web browser. The application runs on the service provider's servers, which handle all the processing and data storage. This allows customers to access the software from any device with an internet connection, providing flexibility and mobility. The service provider manages software maintenance, including updates, security, and backups, so customers always have the latest features and security patches.
From a technical perspective, SaaS providers use multitenant architecture, meaning a single instance of the software serves multiple customers. This approach optimizes resources and reduces costs, as infrastructure and maintenance expenses are distributed across many customers. SaaS applications are also highly scalable, allowing customers to easily adjust their subscription levels based on their needs, whether that means adding features, increasing storage, or supporting more users.
Overall, SaaS simplifies software management for customers, providing a cost-effective and convenient way to access powerful applications without the complexities of traditional software deployment.
- SaaS delivers software applications online, allowing users to access and use them without worrying about underlying infrastructure or maintenance. Examples include email services, customer relationship management (CRM) systems, and office productivity tools.
- Platform as a service (PaaS) provides a complete cloud-based environment for developers to build, deploy, and manage applications—all without the need to manage infrastructure. PaaS also offers tools and services for application development, such as databases, middleware, and development frameworks.
- Model as a service (MaaS), like SaaS and PaaS, uses a cloud-based delivery model but is specifically designed for machine learning models. While SaaS and PaaS cater to a wide range of applications, MaaS focuses on AI use cases. This specialization enables MaaS to provide highly efficient and optimized solutions for ML models, helping organizations quickly deploy AI-powered solutions that drive business outcomes.

Frequently asked questions
- Software as a service (SaaS) is a way of delivering software over the internet. Instead of installing and maintaining software on your computer, you access it online through a subscription with a cloud service provider. This makes it easy to use, update, and scale according to your needs.
- Azure AI services are an example of SaaS. These services help developers and organizations quickly build AI-powered applications without requiring them to manage the underlying infrastructure. They include natural language processing, search, monitoring, translation, speech, vision, and decision-making.
- A SaaS company provides software on a subscription basis, hosting it in the cloud for customers to access via the internet without installation. These companies offer scalable solutions, allowing customers to adjust their plans as needed. They manage automatic updates, ensuring users always have the latest version. Most SaaS companies use a multitenancy model, where multiple customers share the same infrastructure while maintaining separate data and configurations.
- SaaS is often offered on monthly subscription basis. Some providers also offer annual plans—often at a discounted rate.
- Starting a SaaS business might be a strong opportunity. SaaS offers recurring revenue, scalability, and lower distribution costs. However, it also requires significant investment in development, marketing, and customer support. With a strong product idea and a solid execution plan, a SaaS business has the potential to be highly profitable.
