The overall evolution towards microservices has caused a lot of IT leaders to radically rethink architectures and platforms. One can hardly keep up with the rapid onslaught on new distributed technologies. The same people who just asked yesterday "how can we deploy Docker containers?", are now asking "how can we operate Kubernetes-as-a-Service on-premise?", and are about to start asking "how can we operate the open source frameworks of our choice, such as Spark, TensorFlow, HDFS, and more, as a service across hybrid clouds?”. This session will discuss: Challenges of orchestrating and operating
KubeCon Prometheus Salon -- Kubernetes metrics deep diveBob Cotton
Kubernetes generates a wealth of metrics. Some explicitly within the Kubernetes API server, the Kublet, and cAdvisor or implicitly by observing events such as the kube-state-metrics project. A subset of these metrics are used within Kubernetes itself to make scheduling decisions, however other metrics can be used to determine the overall health of the system or for capacity planning purposes.
Kubernetes exposes metrics from several places, some available internally, others through add-on projects. In this session you will learn about:
- Node level metrics, as exposed from the node_exporter
- Kublet metrics
- API server metrics
- etcd metrics
- cAdvisor metrics
- Metrics exposed from kube-state-metrics
Join this session to learn about how these metrics are calculated, their use within Kubernetes scheduling decisions and application in monitoring, alerting and capacity planning. This session will also cover the new metrics implementation/proposals that are to replace the cAdvisor metrics in Kubernetes 1.8.

Storage tiering and erasure coding in Ceph (SCaLE13x)Sage Weil
Ceph is designed around the assumption that all components of the system (disks, hosts, networks) can fail, and has traditionally leveraged replication to provide data durability and reliability. The CRUSH placement algorithm is used to allow failure domains to be defined across hosts, racks, rows, or datacenters, depending on the deployment scale and requirements.
Recent releases have added support for erasure coding, which can provide much higher data durability and lower storage overheads. However, in practice erasure codes have different performance characteristics than traditional replication and, under some workloads, come at some expense. At the same time, we have introduced a storage tiering infrastructure and cache pools that allow alternate hardware backends (like high-end flash) to be leveraged for active data sets while cold data are transparently migrated to slower backends. The combination of these two features enables a surprisingly broad range of new applications and deployment configurations.
This talk will cover a few Ceph fundamentals, discuss the new tiering and erasure coding features, and then discuss a variety of ways that the new capabilities can be leveraged.
Storage 101: Rook and Ceph - Open Infrastructure Denver 2019Sean Cohen
Starting from the basics, we explore the advantages of using Rook as a Storage operator to serve Ceph storage, the leading Software-Defined Storage platform in the Open Source world. Ceph automates the internal storage management, while Rook automates the user-facing operations and effectively turns a storage technology into a service transparent to the user. The combination delivers an impressive improvement in UX and provides the ideal storage platform for Kubernetes.
A comprehensive examination of use cases and open problems will complement our review of the Rook architecture. We will deep-dive into what Rook does well, what it does not do (yet), and what trade-offs using a storage operator involves operationally. With live access to a running cluster, we will showcase Rook in action as we discuss its capabilities.

OSCON 2014 - API Ecosystem with Scala, Scalatra, and Swagger at NetflixManish Pandit
In this talk I’d like to introduce the Scala-based API stack at Partner Innovation Group at Netflix. After seeing a massive growth in the business model and the device ecosystem, we needed a system that could scale and be flexible at the same time. Scala provided the answer and we started with a basic set of APIs which, since then, has evolved towards complex but flexible business flows. Supporting metadata for over hundreds of brands and thousands of devices, the API development has followed a well thought-out, test-driven approach, git-flow, and what most API developers dread – documentation. I will talk about the architecture of the RESTful APIs, and the development + deployment process. We use Netflix-OSS components heavily in the architecture and cloud deployment, so I will cover them as well.
Swagger is what we used for type-safe documentation, which is really easy to use and integrate. I will briefly talk about customizations we’ve done to Swagger in order to make it far more usable at Netflix.
Throughout this effort there were lessons to be learnt, and plenty of best practices and recommendations for anyone starting out to build RESTful APIs, regardless of the platform or stack of choice. It’d be a great opportunity for me to walk through the architecture, and talk about the various components, technologies, and practices that are seeing increasing adoption in the modern, API driven landscape.
As more workloads move to severless-like environments, the importance of properly handling downscaling increases. While recomputing the entire RDD makes sense for dealing with machine failure, if your nodes are more being removed frequently, you can end up in a seemingly loop-like scenario, where you scale down and need to recompute the expensive part of your computation, scale back up, and then need to scale back down again.
Even if you aren’t in a serverless-like environment, preemptable or spot instances can encounter similar issues with large decreases in workers, potentially triggering large recomputes. In this talk, we explore approaches for improving the scale-down experience on open source cluster managers, such as Yarn and Kubernetes-everything from how to schedule jobs to location of blocks and their impact (shuffle and otherwise).

In this deck from FOSDEM'19, Thomas Schwinge presents: Speeding up Programs with OpenACC in GCC.
"Proven in production use for decades, GCC (the GNU Compiler Collection) offers C, C++, Fortran, and other compilers for a multitude of target systems. Over the last few years, we -- formerly known as "CodeSourcery", now a group in "Mentor, a Siemens Business" -- added support for the directive-based OpenACC programming model. Requiring only few changes to your existing source code, OpenACC allows for easy parallelization and code offloading to accelerators such as GPUs. We will present a short introduction of GCC and OpenACC, implementation status, examples, and performance results.
OpenACC is a user-driven directive-based performance-portable parallel programming model designed for scientists and engineers interested in porting their codes to a wide-variety of heterogeneous HPC hardware platforms and architectures with significantly less programming effort than required with a low-level model."

Blockchain (and Cryptocurrency) is an evolution of 20-year old research from scientists like Chaum, Lamport, and Castro & Liskov. Due to the current hype, it's hard to distinguish beneficial aspects of the technology from a desire for a "silver bullet" for device security, verifiable logistics, or "saving democracy". The problem: blockchain introduces new security challenges - and blind adoption without understanding reduces overall security. In this talk, Melanie Rieback and Klaus Kursawe explain the pitfalls and limits of blockchain, so you can avoid making your applications LESS secure.

Performance tests are not only an important instrument for understanding a system and its runtime environment. It is also essential in order to check stability and scalability – non-functional requirements that might be decisive for success. But won't my cloud hosting service scale for me as long as I can afford it? Yes, but… It only operates and scales resources. It won't automatically make your system fast, stable and scalable. This talk shows how such and comparable questions can be clarified with performance tests and how DevOps teams benefit from regular test practise.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
