Cloud Foundry is an open source cloud platform as a service (PaaS) on which developers can build, deploy, run and scale applications. VMware originally created Cloud Foundry, and it is now part of Pivotal Software, whose parent company is Dell Technologies.

Cloud Foundry is licensed under Apache 2.0 and supports Java, Node.js, Go, PHP, Python, Ruby, .NET Core and Staticfile. The open source PaaS is highly customizable, allowing developers to code in multiple languages and frameworks. This eliminates the potential for vendor lock-in, which is a common concern with PaaS.
Developers choose Cloud Foundry for its free, open source nature and for the ability to use their own tools and code. Organizations can deploy Cloud Foundry PaaS on their own internal infrastructure; on cloud providers’ infrastructure, such as Amazon Web Services or OpenStack; or on Cloud Foundry-certified platforms, including IBM Bluemix Cloud Foundry, Pivotal Cloud Foundry, SAP Cloud Platform, Huawei FusionStage and Swisscom Application Cloud.
Cloud Foundry components
According to the Cloud Foundry Foundation, the Cloud Foundry platform is made up of seven core groups of components:

developers at Pivotal, discuss
the fundamentals of Cloud Foundry
and provide a tutorial at
the 2016 Cloud Foundry Summit.
- Routing. Directs traffic coming into the Cloud Foundry platform to the appropriate component.
- Authentication. Contains an OAuth2 server and login server for user identity management.
- Application Lifecycle. Provides application deployment and management services. It includes the Cloud Controller, a service that pushes or deploys an application to Cloud Foundry; pieces of Cloud Foundry’s Diego architecture for the management of containerized applications; and nsync, which monitors the state of an application.
- Application Storage and Execution. Contains a Blobstore repository for large files, as well as Diego Cell, another component of the Diego architecture. Every virtual machine (VM) has a Diego Cell that manages when an application starts and stops, as well as the VM’s containers.
- Service Brokers. Helps link applications to certain services, such as databases.
- Messaging. Provides the ability for VMs to communicate through HTTP or HTTPS protocols. It includes the Consul server, which stores long-term control data like component IP addresses, as well as the Bulletin Board System (BBS), which stores data that is updated more frequently, such as application status.
- Metrics and Logging. Provides Loggregator, which streams application logs to developers, and the Metrics Collector, which provides data to help organizations monitor their Cloud Foundry environment.
The history of Cloud Foundry
In 2009, VMware engineers Mark Lucovsky, Derek Collison and Vadim Spivak started to lead the team that designed and architected the Cloud Foundry platform. On April 11, 2011, Cloud Foundry was launched by VMware, which called the platform the industry’s first open source PaaS.
In 2012, VMware and its parent company EMC revealed plans to spin off parts of their cloud and software business — including Cloud Foundry — into a new business called Pivotal Software.
In September 2016, Dell Technologies acquired EMC, including its VMware and Pivotal businesses.
Cloud Foundry Foundation members
In February 2014, Pivotal announced its intention to establish an open governance model for the Cloud Foundry platform, as well as create a nonprofit foundation dedicated to advancing the Cloud Foundry technology and vendor ecosystem around it.
The Cloud Foundry Foundation has since grown to more than 50 members, including:
- APL Software
- BNY Mellon
- Dell EMC
- ECS Team
- Fidelity International
- GE Digital
- Grape Up
- Hewlett Packard Enterprise
- JPMorgan Chase
- Redis Labs
- Resilient Scale
- Stark & Wayne
