Definition
Platform as a Service - in Salesforce context, the Lightning Platform (formerly Force.com) which provides a cloud-based development environment where customers build custom applications without managing underlying infrastructure.
In plain English
“PaaS stands for Platform as a Service. In Salesforce context, the Lightning Platform (formerly Force.com) is a PaaS offering. It provides a cloud-based development environment where customers build custom applications without managing servers, databases, or other infrastructure.”
Worked example
A developer at Greenstream Capital builds a custom loan-origination app on Salesforce, using PaaS - Platform as a Service. Salesforce provides the underlying infrastructure (compute, database, storage, network), the runtime (Apex, LWC), the deployment platform, and the security model. She doesn't manage servers, install operating systems, scale capacity, or worry about uptime - Salesforce does all of that. She focuses on building the app: data model, business logic, UI. PaaS is what makes a small dev team able to ship enterprise-grade applications without an enterprise-grade infrastructure team.
Why PaaS matters
PaaS (Platform as a Service) is a cloud computing category where the provider gives customers a platform for building and running applications without requiring them to manage the underlying infrastructure (servers, storage, networking, operating systems). In Salesforce context, the Lightning Platform (formerly called Force.com) is a PaaS offering that lets customers build custom applications using Salesforce's data model, security, automation, and UI tooling, without dealing with infrastructure concerns.
PaaS sits between IaaS (Infrastructure as a Service, where customers manage the OS and runtime) and SaaS (Software as a Service, where customers use a complete pre-built application). The Lightning Platform's PaaS nature is what enables rapid development on Salesforce: developers and admins focus on solving business problems rather than managing servers. The trade-off is being constrained to the platform's capabilities and architectural choices. For most Salesforce customers, the constraint is far outweighed by the productivity benefits.
How organizations use PaaS
Treats Salesforce as their enterprise PaaS for any internal application that needs CRM-style data, security, and automation.
Built multiple custom apps on the Lightning Platform PaaS without ever managing servers or infrastructure.
Trains developers on PaaS concepts to help them understand how Salesforce architectural decisions reflect the platform model.
