What Is Pivotal Cloud Foundry?
Pivotal Cloud Foundry, now Cloud Foundry, is a multi-language, container-based open source cloud-native platform sponsored by VMware Tanzu. Primarily community-developed, Cloud Foundry operates as a 501c6 organization.
But how did Pivotal Cloud Foundry come to be such a popular cloud-native platform, and will it continue to be a popular platform in the future? This article explores the basics of Pivotal Cloud Foundry, including an overview of Cloud Foundry, its pros and cons as a platform, available distributions and technologies, and a look at Pivotal Cloud Foundry competitors.
Pivotal Cloud Foundry Overview
According to the Cloud Foundry website, Cloud Foundry is used predominately by large enterprises operating large scale, and often multi-language, cloud applications. With a combination of frameworks, services, and clouds, Cloud Foundry is used by thousands of companies across all industries.
A Brief History of Cloud Foundry
Cloud Foundry was originally developed by VMware in 2009, and announced for public availability in 2011. Two years later, Pivotal was formed, and as steward, led Cloud Foundry into the open source era.

Pivotal Cloud Foundry Distributions
With distributions that range from government-compliant to microservices-focused, Cloud Foundry distributions run the gamut of cloud functionality.
Cloud Foundry has 7 certified distributions:
- Atos - Offers cloud transformation, migration, and automation services.
- Cloud.gov - Offers U.S. government-compliant cloud services.
- IBM Cloud Foundry - Offers public and enterprise Cloud Foundry-based PaaS.
- SAP Cloud Platform - Offers enterprise PaaS based on Cloud Foundry, with app development services.
- SUSE Cloud Application Platform - Offers application delivery platform focused on Cloud Foundry and Kubernetes
- Swisscom Application Cloud - Offers secure, dedicated environments with private networks.
Of these distributions, IBM Cloud Foundry and SAP Cloud Platform are the most used.
4 Notable Cloud Foundry Technologies
With more and more companies making a transition to microservices, and the demand for cloud-based applications on the rise, technology and situation-specific distributions help to solve issues for developers who want to use Cloud Foundry.
1. KubeCF: Kubernetes-Native Cloud Foundry Distribution
The Cloud Foundry KubeCF distribution combines the comprehensive utility of Kubernetes, with the infrastructural simplicity of Cloud Foundry.
2. Eirini: Reuse Existing Kubernetes Cluster Infrastructure
Cloud Foundry Eirini is an incubation project based on existing Cloud Foundry efforts. Eirini makes it easy to enable scheduling for the Cloud Foundry Application Runtime, or CFAR.
3. Quarks: Package CFAR as Containers
Cloud Foundry Quarks is another incubation project based on existing Cloud Foundry efforts. Quarks is designed to help standardize the developer and operational experience — allowing for fewer infrastructure considerations.
4. BOSH: Any Cloud Compatibility for Releases and Runtime
Cloud Foundry BOSH manages runtime layers, and allows for deploying (and monitoring) complex, distributed Cloud Foundry application deployments.
Pivotal Cloud Foundry Pros and Cons
While Cloud Foundry doesn't have nearly the market share as other big cloud-based platforms, it does have some benefits that make it a good choice for some developers. This list of pros and cons goes over a few of the benefits, and common complaints, against Cloud Foundry.
| Pros | Cons |
|---|---|
| Open source, free platform | Steep learning curve |
| Great for large, enterprise projects | Not suitable for many small-scale applications |
| Mature, full support | Platform as a service |
| Multiple well-supported distributions | |
| Works with many languages | |
| Infrastructure and cloud agnostic | |
| Great for horizontal scaling |
Because Pivotal Cloud Foundry is open source and offers mature, specialized distributions for a variety of languages, and offers the ability to deploy on premises cloud networks, it can be a popular choice for cloud-based applications. But because other companies like AWS have such a big stake in cloud services and infrastructure, Pivotal Cloud Foundry may remain on the enterprise periphery of the overall cloud PaaS landscape.
Pivotal Cloud Foundry Competitors
Early competitors for Cloud Foundry focused on the limitations of their platform, with container orchestration technologies like Kubernetes and Docker Swarm emerging as infrastructure as a service foils to the Cloud Foundry platform as a service. While Docker Swarm isn't as talked about anymore, the Cloud Foundry foundation has put a clear focus on providing stable and user-friendly Kubernetes integrations (and distributions like KubeCF).
The true competitors to Pivotal Cloud Foundry now, especially in terms of large enterprise-scale applications, are other PaaS platforms like AWS Elastic Beanstalk and Google App Engine.
Pivotal Cloud Foundry vs. Kubernetes
In the past, there was a debate over Cloud Foundry vs. Kubernetes, as Kubernetes was developed in part to solve orchestration issues that Cloud Foundry could not. But, as Kubernetes has become the de-facto standard in container orchestration (even overtaking Docker Swarm), Cloud Foundry has developed integrations and a distributions that make using Kubernetes orchestration within Cloud Foundry easy.
Final Thoughts
For large enterprise companies, Cloud Foundry offers an easily-extensible and mature way to build and deploy large-scale cloud-based applications. With the ability to foster on-premise cloud applications, specialized distributions for enterprise niches, and integrations with popular orchestration technologies, Cloud Foundry is a powerful tool for large, enterprise companies.
