Cloud Foundry Day Europe 2024

In this talk you'll explore how the Cloud Foundry business case is still alive and that there might be an increase of momentum in the Cloud Foundry ecosystem. Kubernetes is versatile and its community is growing fast. However, the hypothesis that Kubernetes will fully cannibalize Cloud Foundry territory did not come true. Large scale Cloud Foundry environments running lots of cloud native applications provide a much better economy of scale compared to Kubernetes environments. With a closer look at the issues arising from using Kubernetes in large scale environments, you will learn how the operational efficiency of large Cloud Foundry environments remains superior for a range of workloads.

We all love the smooth “push” experience that Cloud Foundry brings along. But all the cool kids want to run on Kubernetes these days. Meet Korifi - your ticket to the Kubernetes ecosystem. Sounds interesting? Hop on the train and let us share the lessons we learned while trying to integrate Korifi into the SAP Business Technology Platform. Spoiler alert: it has not been a smooth ride.

Estimating and understanding cloud costs is difficult exercise. It gets even more complex when attempting to do this with Kubernetes at scale. What really obfuscates it the most is when you install an abstraction that is meant to manage build, deployment, scaling, and all other functions. OpenCost lifts the veil on Kubernetes spending. This open-source project delivers real-time cost allocation, giving you a detailed breakdown from entire deployments down to individual containers. It integrates seamlessly with major cloud providers (AWS, Azure, GCP) and even supports on-premises clusters, ensuring dynamic asset pricing for all Kubernetes environments. When applied to Korifi, it tells us many things. In this talk, I intend to explore what it costs to operate the tool on Kubernetes clusters. Can we find out what a build costs? Can we ascertain the cost of scaling an instance? Come to the talk to find out!

This session presents new and exciting features brought to Cloud Foundry by the App Runtime Interfaces working group. The working group covers Cloud Controller, CF CLI and clients, Buildpacks, Autoscaler and MultiApps. You will hear about Cloud Native Buildpacks, CAPI performance improvements and Puma, steps on the migration path towards CF API v3 and more. Finally, I will give an outlook about the next planned features.

Currently, the Cloud Foundry routing stack does not support the configuration of features for a specific route. A case in point is the load balancing algorithm between Gorouters and backends. This algorithm is defined globally and is utilized generically to distribute requests among available backends for a given route. The ability to define the load balancing algorithm on a per-route basis could help in optimizing the use of application instances, based on the workloads on the application side. In this talk Tamara and Max, on behalf of the SAP BTP CF Routing team, present several scenarios for which a more flexible approach of per-route functionalities can provide benefits. They are going to highlight a proposed solution that keeps the implementation overhead as simple as possible. Furthermore, they will talk about the current implementation state and challenges we have encountered. This talk is intended to raise some further discussions and ideas that could be integrated as a per-route feature.

This session will explore how leveraging economies of scale can lead to significant cost optimizations in Cloud Foundry environments. Participants will learn strategies for maximizing resource utilization, reducing operational expenses, and achieving efficient scaling in cloud deployments. Through real-world case studies, we'll illustrate successful implementations and best practices for cost-efficient cloud management. Attendees will leave with actionable insights to enhance their cloud infrastructure's economic efficiency and scalability. Join us to uncover practical methods to optimize costs and drive value in your Cloud Foundry operations.

Our clients frequently express a paradoxical need: They value the developer experience and production readiness of Cloud Foundry (CF) but simultaneously seek novel and innovative solutions. While they are committed to utilizing CF for the next 3 to 5 years, or even up to a decade, they are also exploring new, cutting-edge technologies. This presentation will address how to overcome this challenge by modernizing CF while retaining its core strengths. We will discuss how advanced customization tools can enhance CF's cost efficiency and how integrating AI can further improve the developer experience through automation and performance optimization. This session will provide key insights, resources, and strategies to ensure CF remains a compelling solution for the foreseeable future.
