Cloud Foundry / Cloud Foundry Day 2022

Cloud Foundry Technical Governance: Past, Present, and Future - Eric Malm, VMware

Do you have a feature you want to contribute to Cloud Foundry, but you're not sure how to get it accepted? Do you want to get more involved in the community and are looking for a good place to start? After nearly a year of preparation, in 2021 the Cloud Foundry Foundation moved to a new model of project and technical governance designed to provide more transparency and inclusivity to all contributors. Since then, the community has elected two Technical Oversight Committees, formed eight Working Groups to oversee Cloud Foundry projects, and iterated on the roles and processes that make sense for contributors to our community. Let's look back over the progress we've made in the past couple of years and see what remains to be done to make Cloud Foundry a welcoming, productive community for contributors of all levels.

App Runtime Interfaces Extravaganza! - Greg Cobb, VMware

You won't want to miss this talk!

Grappling with Kubernetes Eventual Consistency in Korifi - Tim Downey, VMware

Historically, the Cloud Foundry APIs have been backed by a relational SQL database. This provided atomicity and strong consistency for each request and many of the CF APIs and clients now rely on those guarantees. With Korifi we no longer have that luxury. Korifi’s CF APIs maintain state through Kubernetes custom resources (CRDs) that are backed by an eventually consistent etcd key-value store. That means that when interacting with the Kubernetes API you are not guaranteed to be able to read data back immediately after writing it – but you will be able to eventually. As you might imagine, this behavior can cause trouble if it is not accounted for. In this lightning talk, Tim Downey will discuss some of the problems with eventual consistency we have encountered while reimplementing the CF APIs in Korifi and how we have worked around them.

How we Modernized and Reduced the Infrastructure Costs for Running CF - David Stevenson, VMware

The infrastructure costs associated with running CF have traditional been a significant burden for operators and experimenters alike. David takes us through the process of modernizing CF and BOSH to use next-generation infrastructure, including some exciting drama discovered along the way. Finally he'll highlight how your CF deployment can be saving significant money by leveraging the next generation of Hyperscaler VM types.

Introducing Korifi: The Evolution of CF on Kubernetes - Dr. Dave Walter & Andrew Wittrock, VMware

The CF on K8s working group has decided to take a new approach to bringing the Cloud Foundry API to Kubernetes with Korifi. Korifi is a ground-up reimplementation of the Cloud Foundry API contract, backed by Kubernetes Custom Resources, Controllers, and Webhooks. In this session, we will dive into Korifi’s Custom Resources and how they simplify application deployment on Kubernetes - including a live demo of the platform in action. We’ll walk through how they fit together and how we leverage existing Kubernetes ecosystem projects such as Contour and Kpack to provide a fast, secure, and extensible platform.

Keynote: Cloud Foundry - The Standard for Developer Experience and its Evolution Forward - Catherine McGarvey, VP Software Engineering, VMware

Cloud Foundry Foundation successfully established norms in a developer platform with operational elegance, intuitive patterns, and abstraction of clouds. In a paradigm shift of the underlying infrastructure what outcomes and patterns highlight it's continued relevance. A look at what CFF has achieved this year and what ecosystem opportunities lie ahead.

New Features in BOSH: Improved NATS cert rotations - Maya Rosecrance, VMware

Maya will cover a short overview of features shipped in the BOSH director and embedded releases in the last year. From IMDS V2 to Template Rendering Speed improvements, we'll go through a quick and dirty overview of what's new in BOSH with a focus on the improvements to the rotation of NATS Certificate Authorities. This talks is or anyone that hasn't been closely following the work of the BOSH Ecosystem TOC and uses BOSH.

Recap: Ten Years of Working With Cloud Foundry - Julian Fischer, anynines GmbH

In this talk anynines CEO Julian Fischer shares ten years of history working with Cloud Foundry. He talks about the transformation of Cloud Foundry as a technology as well as its unique community. It's been a fantastic journey from hearing the word Cloud Foundry for the first time to transforming an entire company into an organization focused on application development platforms ... and the story goes on. Learn about how the zeitgeist has forged Cloud Foundry throughout the years. See how changes of the CF architecture have adapted to an ever changing context. Be entertained by tales collected from planning and operating dozens of different Cloud Foundry environments for various, vastly different organizations and purposes. These tales tell about small and large CF environments with few dozens to thousands of apps. Moreover, they tell about challenges of changing technologies, security in the enterprise and emerging friendships among the Cloud Foundry community. A projection on how existing Cloud Foundry environments may evolve will be presented and Cloud Foundry's future potential illustrated. At the end of the talk you will have gathered an impression on how unique Cloud Foundry is from both perspectives: as a technology and as a community.

Remote Debugging of .NET Core applications with Paketo Buildpacks + Visual Studio Code - Timothy Hitchener, VMware

Remote debugging can provide insight into the behaviour and interactions of complex applications running in remote machines/containers. This practice is supported for .NET Core applications via the Visual Studio Debugger (vsdbg), which the Paketo Buildpack for .NET Core can now optionally include in your application image via an environment variable passed at build time. The debugger can attach to a running .NET Core process and be bound to a client-side debugger via STDIN across a connection invoked via a transport program (e.g. ssh, docker exec or kubectl exec). Using Paketo Buildpacks with Omnisharp's C# extension for Visual Studio Code, .NET Core users can take advantage of a powerful workflow for accelerating iterative development.

Stemcells are now Jam-packed with Jelly(fish) - Long Nguyen, VMware

It's a new year jam-packed with new stemcells! Learn about the new stemcell Jammy Jellyfish and the journey of how it was created. Find out about the new features that come with Jammy and the challenges that come with a new operating system. Learn how to update your BOSH releases to support Jammy.

The Future of Logs and Metrics in Cloud Foundry - Carson Long, VMware

The CF community is no stranger to complicated diagrams, but it's rare that they get as complex as the current logging and metrics architecture: multiple versions of Loggregator are deployed in tandem, agents are mostly involved but not ubiquitous, an instance group exists purely to buffer logs. Carson Long presents the new, old vision for logging and metrics in Cloud Foundry: Shared-Nothing.

What's new with Paketo Buildpacks? - Sophie Wigmore & Ryan Moran, VMware

The Paketo Buildpacks project has been pretty busy this year developing new features to make containerizing your application, in a number popular languages, easier than ever. With new features such as support for a software bill of materials (SBOM), remote debugging, and live-reloading to name a few, Paketo maintainers and contributors are driving forward the Cloud Native Buildpacks experience. At this session, attendees will get a Paketo project update, as well as first-hand insights into how to leverage the power of buildpacks to get secure and performant builds.
