## **Cloud Foundry**&#x20;

Cloud Foundry is a well-establish open source PaaS offering that boasts a straightforward workflow to go from source code to a running application. Minimally, to use Cloud Foundry, a single configuration file with the application’s runtime, name, and required memory is required. A single cf push command starts the build and deployment processes. Once successful, a publicly accessible route is created, and your application will start receiving traffic.&#x20;

#### **Cloud Foundry** &#x20;

* Cloud Foundry is an open-source project that implements PaaS. Cloud Foundry has a container-based architecture that runs apps in any programming language.&#x20;
* PaaS implementations allow developers to focus exclusively on code without worrying about the underlying infrastructure.&#x20;
* Cloud Foundry on IBM Cloud is lite plan compatible and has built-in benefits like auto-scaling, auto-routing, and health management.

## **Cloud Functions**

* Cloud Functions on IBM Cloud are built on the Open Source project OpenWhisk that implements FaaS.&#x20;
* Cloud Functions are broken up into Actions, Triggers, and Sequences.&#x20;
* Cloud Functions on IBM Cloud are lite plan compatible and has built-in benefits like 5M free executions, tight integration with other providers, and an integrated API gateway.&#x20;

**Serverless**&#x20;

Cloud Functions, IBM Cloud’s Function-as-a-Service capability is based on the Apache OpenWhisk project and provides serverless functionality. With Cloud Functions you don’t deploy an application that runs waiting for work. You write code that is run as an action, which is triggered when a defined event occurs. Until such an event occurs your action is not executed. Actions are scaled up and down as needed by the cloud provider, this results in no maintenance overhead for the code being run, hence the term serverless. &#x20;
