Cloud Foundry / Cloud Foundry Summit Europe 2020

101 Open Service Broker API – Getting to Know the Open Service Broker API - Christian Brinker & Marco di Martino, evoila

Cloud Foundry provides its users with a standardized runtime environment making it easy to push code to production. But when it comes to a productive usage of application, they depend on other necessary components like databases, message queues or log aggregators. But these also have to be provided in a standardized and fast way to speed up a software development process. The solution is called ‘Service Broker’. But how is Cloud Foundry able to make use of such different technologies. The anwser is called ‘Open Service Broker API’. In their talk Christian Brinker and Marco di Martino take the audience on the journey from the reasons for the usage of service brokers via their inner structure and effects to complex production setups. They explain the Open Service Broker API, how to use and implement it. They also present common pitfalls and best practices.

A Journey Through BOSH and BOSH DNS Monitoring - Beyhan Veli, SAP

The BOSH team at SAP operates BOSH as a service for the cloud platform operators and the Cloud Foundry on-demand service brokers. We are also responsible for BOSH DNS, which is used for DNS and service discovery in our Cloud Foundry environments. Like every production service, the performance and availability expectations are very high, because any failed DNS resolution or BOSH operation can have direct customer impact.

Motivated by concrete issues in our production environments, we have continuously worked on identifying the useful metrics and making them available to monitoring tools. No one likes to be paged and that is why it was a crucial task for us to improve the BOSH and BOSH DNS monitoring and define meaningful alerts.

In this talk we share the story of our monitoring journey and the evolution of the metrics which we identified over the time to prevent critical situations on productive environments. Moreover, we will give an update on all the improvements implemented for BOSH and BOSH DNS to make a more sophisticated monitoring possible and the available options to expose those metrics to monitoring tools.

A Set of Tools for Any Kubernetes Project - Mario Manno & Venkata Krishna Rohit Sakala, SUSE

In our effort to build an operator that can deploy Cloud Foundry on Kubernetes, we've discovered several opportunities for features. We'd like to demo these capabilities to the Cloud Foundry community. These can be useful for core contributors to Cloud Foundry, but also users of Kubernetes that have encountered the same limitations as we did. Secret generation, canary deployments, server-side templates, config change detection, feature-rich jobs and more.

App Logging in Cloud Foundry for Kubernetes - Travis Patterson & Jesse Weaver, Vmware

Transitioning to Cloud Foundry for Kubernetes has allowed the Logging and Metrics team at VMware to dramatically rethink and simplify the CF logging experience. In this presentation we'll talk about the new architecture, what operators can expect right now, and upcoming improvements.

Bring-Your-Own Service Mesh to Cloud Foundry - Andy Paine, EngineerBetter

Andy Paine will demonstrate how he used some advanced Cloud Foundry features including container-to-container networking, sidecars and metadata to deploy Hashicorp Consul as just a normal SpaceDeveloper. This will involve deploying the Consul control plane in a way that allows it run automatic leadership elections as well as deploying applications with the Consul + Envoy sidecars that register applications into the service mesh.

Carvel in Action with CF for K8s - Dr. Dave Walter, Vmware

Integrating the myriad of YAML documents that make up the CF for K8s platform is no small task. Fortunately, we have the Carvel suite of tools (formerly known as K14s) in our toolbox. This talk explores the ways in which the CF Release Integration team have made use of vendir, ytt and kapp to pull together a variety of components. Attend this talk and learn how Carvel tools are used to:

* incorporate and extract subdirectories containing K8s templates from other repositories with vendir
* limit the blast radius of ytt overlays by using dynamic library loading
* define custom kapp change and wait rules to provide a better operator deployment experience

Cloud Foundry for Everyone! - Matthias Haeussler & Thorsten Jakoby, NovaTec Consulting GmbH

This talk will give an overview of the various possibilities to easily access and get in touch with the Cloud Foundry platform. Cloud Foundry comes in various flavors, there is a big range of commercial hosted offerings, private deployment options and various development environment alternatives. This presentation is intended for users who would like to get their first hands-on experience or for others who might want to evaluate an alternative deployment option. The analysis will compare the public offerings based on the metrics of price, availability, options and available services as well as the self-deployed options in terms of simplicity in setup and handling and requirements. It is supposed to cover the breadth of the Cloud Foundry offerings and give an easy entry path to the technology. This is an updated version of the talk with strong focus on new Kubernetes-based options

Cloud Foundry on K8s - Path to the Next Generation - Patrick Hartz & Martin Valencia Flores, anynines GmbH

Even now when Kubernetes is becoming more and more popular CF is still a great choice to make micro services available to the outer world. The portability of applications, the easiness of scaling and the dynamic routing are just some benefits. Nowadays VMs are starting to be left behind in favor of containers, and CF is a prime candidate to bring to Kuberntes. For all the reasons mentioned above, and for the user experience that has been gained and built over the years. Progress does not imply starting with a totally clean slate, progress is built upon strong foundations. In this talk we will take you with us on our journey, and tell you why and how we deployed CF on Kubernetes and what challenges came along this road.

Deep Dive: CF API on K8s - Piyali Banerjee & Michael Gresham, Vmware

What happens when the strengths of Cloud Foundry and Kubernetes are combined? A radically enhanced experience for developers and operators. This talk provides an overview of the work the CF API team (CAPI) has done over the past year to evolve the Cloud Foundry API to work natively with Kubernetes. Piyali will cover how the CF API server and related components are organized in the cluster, and how major workflows supported by the CF API (i.e.: app staging, stack updates, deployment) works in a system without BOSH and Diego through some exciting demos! Mike (CAPI PM) will share what CAPI’s roadmap will look like for the rest of 2020.

Running a Publicly Available Developer Sandbox - Andrew Gracey, SUSE

So, you've built your platform, what next? How do you get users onboarded? How do you make sure everything works externally? How do you stop problems before they occur? In running the SUSE Developer Sandbox, we've learned a lot about the rough edges of Cloud Foundry and have found some nice ways to smooth them out. Join me for a talk about the lessons we've learned in the last 6 months and 500 users!

SUSE and Cloud Foundry: Helping Customers Simplify, Modernize, and Accelerate - Troy Topnik, SUSE

SUSE has been at the forefront of adopting Kubernetes as a platform for running Cloud Foundry. As part of our mission to help our customers adopt cloud-native technologies, we've learned that the path to successful utilization of Kubernetes can be difficult - for end user software developers, for platform operators, and even for Cloud Foundry itself. This session will summarize how KubeCF, Quarks, and Stratos are building a bridge for platform operators from current BOSH-based releases to the next generation of Cloud Foundry components currently under development.

Service Broker Integration with Kubernetes Operators - Julian Fischer, anynines GmbH

Cloud Foundry can be run on top of or alongside Kubernetes. Simultaneously, Kubernetes becomes more popular for automating data services and in particular the operator pattern is applied frequently. In this talk you will get a brief introduction into the operator pattern and how it works. Furthermore, it will be discussed how operators can be integrated with Cloud Foundry using Service Brokers. After this talk you will have a conceptual understanding of operators and how they might fit into your Cloud Foundry marketplace.

If you don't know what Stratos is, or you want to hear what the team has been up to, this is the talk for you.

The Diversity Conversation: Making the Invisible Visible: Seeing, Respecting, and Valuing Care and Maintenance in our Code and Beyond - Lauren Bacon, &yet

Introduction by Caitlyn O’Connell, Cloud Foundry Foundation.

This year's COVID-19 pandemic has pulled back the curtain on the role of care work within our individual, social, and collective lives. While many of us in the tech sector have experience working remotely and from home, few of us have done so under such extreme and trying circumstances.

In particular, parents with children living at home have been navigating a new world of remote schooling and loss of childcare in an economy that tends to treat child-rearing and other forms of care work as externalities, rather than as central to our lives. In her talk, Lauren Bacon explores the ways in which care work is and isn’t noticed or valued, especially in the tech sector -- and what each of us can do to make that invisible work more visible, more clearly understood -- and ultimately, more valued.

The Diversity Conversation is dedicated to subjects relating to diversity, equity and inclusivity. It is a session open to all Summit attendees. We invite you to attend this event regardless of your prior experience with these topics. It is our hope that you leave the Diversity Conversation inspired and with a call to action, whether it’s a workshop to take, a conversation to have, a book to read, a practice to implement, or a question to ask.

Up and Running with Prometheus in CF for K8s - Kaitlin Barrer, Vmware

Prometheus, an open-source metrics-based monitoring system, has become a widely adopted and standardized format for emitting metrics. It is the monitoring tool of choice for Kubernetes and Docker and is the standard for metrics in CF for K8s. This lightning talk will demonstrate how to get up and running with Prometheus in CF for K8s via ytt. Topics covered include: * How contributors to CF for K8s can setup components to emit Prometheus metrics * How application developers can deploy their application to emit Prometheus metrics * How to use Prometheus to monitor and gather useful information about the platform and deployed applications
