Why Cloud Foundry is Making the Open Service Broker API Even More Open

by December 13, 2016

Since becoming the Executive Director for Cloud Foundry, I have been eagerly awaiting today’s launch of the Open Service Broker API project. This collaborative project with Fujitsu, Google, IBM, Pivotal, Red Hat and SAP enables developers, ISVs and SaaS vendors to deliver services to applications running within cloud-native offerings — including Cloud Foundry, OpenShift and Kubernetes — in the most straightforward, effective way possible.
Part of what I love so fiercely about the open source world is the ability to shed ego, come together to collaborate and to envision a radically open future.

Cloud Foundry: What’s the state of the project?

by October 20, 2016

With thousands of contributors and more than 130 core committers on Cloud Foundry, it can be challenging to keep up with the state of the project. At Cloud Foundry Summit in Frankfurt, Cloud Foundry Foundation VP of Technology Chip Childers provided an up-to-the-minute status report on Cloud Foundry. He kicked off the discussion with the to-be-released incrementally v3 API, moved on to “secret weapon” buildpacks, explained the need to migrate to Diego Runtime and delved into Garden before attacking cf v242’s volume services, container to container networking, route services, “bits” service, isolation segments, Abacus, BOSH “2.0” (“the heart of the Cloud Foundry multi-cloud promise”) and the OpenStack CPI.

Platforms Beat Products, Every Time

by October 8, 2015

Platforms beat products. 10 years ago, that might have not been the popular thinking. However, the latest cloud platforms are beating product. Over at CIO.com today, Bryan Kirschner posted an interesting piece on how platform economics work – and why a product strategy will always lose.
As he puts it: “a successful platform strategy requires upending product strategy assumptions. Products win on features. Platforms win with communities. Value creation must shift from internal optimization to external servicing. Behavior must shift from command-and-control to openness by default.”
He goes on to highlight the three key pillars of a presentation from Cloud Foundry’s CEO, Sam Ramji:

Working with the Cloud Controller API in Ruby: Beyond CFoundry.

by March 24, 2014

Cloud Controller is the primary API through which third parties interact with Runtime; it encapsulates the myriad internal services that take a user from ‘cf push’ to a running application. Both the Pivotal Developer Console (the web application that ships with Pivotal CF and backs console.run.pivotal.io) and the CloudFoundry CLI interact directly with the Cloud Controller API. The two applications were originally written in Ruby and shared a common Ruby code base for talking to Cloud Controller called CFoundry.
CFoundry provides a friendly interface to the Cloud Controller API.

Securing RESTful Web Services with OAuth2

by October 9, 2012

As an active committer on Spring Security OAuth and the Cloud Foundry UAA, one of the questions I get asked the most is: “When and why would I use OAuth2?”
The answer, as often with such questions, is “it depends.” However, I must admit, there are some features of OAuth2 that make it compelling in a wide variety of situations, especially in systems composed of many lightweight web services. This article guides you through updating a system to be secured with OAuth2 and the decision points for choosing to build such a system.
There is a strong trend at the moment towards distributed systems with lightweight architectures based on plain text web services (usually JSON).

High Level Features of the UAA

by July 24, 2012

The User Account and Authentication Service (UAA) in Cloud Foundry is responsible for securing the platform services and providing a single sign on for web applications. A previous article introduced the UAA and placed it in the context of the platform, and here we go into a bit more detail and describe the features of the UAA individually:

Centralized Identity Management
Single Sign On
Delegating Access to Services
User Account Management
Client Application Registration
Other UAA Resources

Centralized Identity Management
Applications that want to act on behalf of a User, for instance to view or push apps to the users Cloud Foundry account, need to authenticate the User against the platform.

Introducing the UAA and Security for Cloud Foundry

by July 23, 2012

Cloud Foundry is a distributed system with many components front and back end. If you are familiar with the Cloud Foundry architecture you have probably noticed that the Cloud Controller exposes its functionality via lightweight HTTP APIs. The internal components also use the same approach to communicate with each other. Up until recently this was done using a custom authentication mechanism which had some drawbacks. This blog post will walk you through the changes that we are making in this area.
We created a new component to handle all external user-facing security concerns named the User Account and Authentication Service or UAA for short. It has been live in cloudfoundry.
