What is software as a service?

Software as a service (SaaS) is a cloud-based model in which users access software applications over the internet, typically through a subscription or pay-as-you-go rather than a perpetual license. Instead of installing and managing software on their own devices or infrastructure, customers rely on the provider to host, maintain, secure, and update the application.

How does SaaS work?

SaaS providers host applications on their own or cloud-based infrastructure, with users typically accessing them through a web browser. SaaS applications commonly use a multi-tenant model, where a single platform serves multiple customers while keeping each customer’s data and access separate. Providers generally handle application maintenance, updates, security, and the underlying infrastructure.

Why is SaaS important?

SaaS gives organizations faster access to new technology without requiring them to purchase infrastructure or manage software themselves. It can simplify IT management and maintenance while shifting software spending toward a predictable subscription model. These advantages have helped make SaaS a major part of how organizations purchase and use business software, helping IT shift spending from capital expenditures (CapEx) to operating expenditures (OpEx).

Benefits and use cases

SaaS gives organizations access to software capabilities without having to develop, host, or maintain them in-house. It’s become a common way to deliver business applications, including customer relationship management (CRM), enterprise resource planning (ERP), e-commerce, security, collaboration, and productivity tools.

Key benefits include faster deployment, frequent software updates, lower infrastructure and maintenance requirements, and greater financial flexibility. SaaS also makes it easier to support distributed workforces because applications can typically be accessed from anywhere with an internet connection. Providers generally manage uptime, software updates, and security patches while also proving data on usage and performance.
