What is SaaS? — UK Software Development Guide
Direct Answer
SaaS (Software as a Service) is a software distribution model where applications are hosted centrally and delivered to customers via the internet, typically on a subscription basis. Unlike traditional software that users install on their own machines, SaaS products are accessed via a web browser — with the software company responsible for hosting, security, updates, and availability.

Article 28 UK GDPR requires a written Data Processing Agreement between the SaaS provider and each customer. UK SaaS providers should use AWS eu-west-2 or Azure UK South to maintain UK data residency for UK customers' personal data.
