SaaS
SaaS (Software as a Service) is a cloud computing model where software applications are hosted and managed by a third-party provider and delivered to users over the internet, typically on a subscription basis. It eliminates the need for users to install, maintain, or update software locally, as the provider handles all infrastructure, security, and updates. This model enables access to software from any device with an internet connection, often through a web browser.
Developers should learn about SaaS to build scalable, multi-tenant applications that can serve a large user base efficiently, as it's widely used for business tools, collaboration platforms, and customer-facing services. It's particularly valuable when creating products that require frequent updates, global accessibility, or lower upfront costs for users, such as CRM systems, project management tools, or streaming services. Understanding SaaS helps in designing cloud-native architectures and integrating with other cloud services.
