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.
Real-World Example
At their company, the IT director at Vertex Global leverages PaaS to scale their operations using the Salesforce platform. PaaS gives them the infrastructure and tools needed to support new business requirements, handle increased data volumes, and serve a growing user base without compromising performance.
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
- •TerraForm Tech — Treats Salesforce as their enterprise PaaS for any internal application that needs CRM-style data, security, and automation.
- •NovaScale — Built multiple custom apps on the Lightning Platform PaaS without ever managing servers or infrastructure.
- •CodeBridge — Trains developers on PaaS concepts to help them understand how Salesforce architectural decisions reflect the platform model.
