Evaluating Cloud Foundry Against the PCI DSS Security Standard

Cloud Foundry adopters come from all areas, including the highly regulated healthcare, finance, and public sectors. A common question is, “Can an open-source platform comply with security standards accepted in our industry?” In this post, I evaluate Cloud Foundry against the requirements of PCI DSS v3.1, a security standard widely used in the financial industry.

Warden is a container implementation currently used in Cloud Foundry. At the same time, Docker is another option to easily and efficiently manage containers. That’s why a lot has been made to enable Docker in the Diego runtime.

Here, I briefly compare Warden and Docker: their implementation, what makes them alike/different, and how they’ll work together in Garden—the new container back end that will become available in Diego.

Until recently, all custom BOSH CPIs were forks of the BOSH project. They were hard to maintain and had to be implemented in Ruby. In August 2014, the BOSH team introduced the new external CPI mechanism that has removed these constraints. The second part of our blog series on adding BOSH support to custom clouds will be dedicated to external BOSH CPIs, how they are used, and what it takes to build one.

How to Remotely Debug Cloud Foundry Apps

Juan Pablo Genovese

How to remotly debug Cloud Foundry applicationsWhen using Cloud Foundry for deploying apps, one might expect that all the test suites will run painlessly and what works in development/testing/staging will work in production. However, what if it won’t? What if it is impossible to replicate those conditions in a non-production environment? Here, remote debugging comes to the rescue.

In this blog post, I provide guidelines on how to remotely debug Ruby and Java applications deployed with Cloud Foundry.
