Cloud Foundry is an open source Platform-as-a-Service (PaaS) technology with broad industry support. SAP Cloud Platform Cloud Foundry environment provides the benefits of the open source Cloud Foundry technology along with several, differentiating enterprise-grade features and functionalities.

A key design principle of Cloud Foundry is to build applications as scalable, stateless microservices that utilise various backing services for persistence, messaging, etc.

Microservices can be developed in practically any programming language as long as there is a corresponding Cloud Foundry buildpack. SAP Cloud Platform provides in-built support for certain buildpacks such as Java and NodeJS and allows use of any other community buildpacks.

SAP Cloud Platform includes several backing services including the flagship SAP HANA as well as other popular open source services such as PostgreSQL, RabbitMQ and Redis.

In addition, the Cloud Foundry environment of SAP Cloud Platform includes various other technical services such as Connectivity, AutoScaling, Security and Job Scheduler.
