High Performance Magnolia with Anycast Routingbkraft
Anycast Routing is an industry best practice to give servers the highest possible uptime, but that's only the network part. Magnolia CMS easily manages to synchronize multiple server nodes when publishing content. That's the content part. We at MiroNet bring the content and the network together and want to talk about our experiences on "The Internet" (literally) with Magnolia and Anycast Routing.
CloudFlare operates a global anycast content delivery network (CDN) to improve website performance and security. Their network routes web traffic through data centers located around the world, where services like caching, security filtering, and optimizations are applied. Anycast routing allows a client to connect to the closest data center, and if that location fails traffic will automatically reroute to the next closest one. Operating an anycast CDN presents challenges around efficient routing, new market deployments, and troubleshooting unusual routing behaviors between networks. Peering is important for reachability but must be considered economically in each region.

Hardware fails, applications fail, our code... well, it fails too (at least mine). To prevent software failure we test. Hardware failures are inevitable, so we write code that tolerates them, then we test. From tests we gather metrics and act upon them by improving parts that perform inadequately. Measuring right things at right places in an application is as much about good engineering practices and maintaining SLAs as it is about end user experience and may differentiate successful product from a failure.
In order to act on performance metrics such as max latency and consistent response times we need to know their accurate value. The problem with such metrics is that when using popular tools we get results that are not only inaccurate but also too optimistic.
During my presentation I will simulate services that require monitoring and show how gathered metrics differ from real numbers. All this while using what currently seems to be most popular metric pipeline - Graphite together with com.codahale metrics library - and get completely false results. We will learn to tune it and get much better accuracy. We will use JMeter to measure latency and observe how falsely reassuring the results are. We will check how graphite averages data just to helplessly watch important latency spikes disappear. Finally I will show how HdrHistogram helps in gathering reliable metrics. We will also run tests measuring performance of different metric classes

Mehr und schneller ist nicht automatisch besser - data2day, 06.10.16Boris Adryan
Das Gesetz der großen Zahlen gilt immer: Die statistische Sicherheit nimmt mit der Anzahl der Datenpunkte immer zu, sofern die Datennahme fair erfolgt. Leider kostet das Sammeln der Daten oftmals Geld, und so ist man vor allem im Bereich der Sensorik (Stichwort: Internet der Dinge) gezwungen, sinnvolle Kompromisse einzugehen. In diesem Vortrag fasse ich die Erkenntnisse eines Projekts zusammen, in dem die Datenanalytik zeigte, dass man zukünftig nur 60% der ausgebrachten Sensoren wirklich braucht. Auch muss es nicht immer Echtzeit-Analyse sein: Mit einer auf den Business-Case abgestimmten Datenstrategie lassen sich unnötige Ausgaben vermeiden.

- The document discusses methods for estimating traffic matrices, which describe the flow of traffic between origin-destination pairs in a network.
- Early methods relied on direct measurements, which are computationally intensive. Recent approaches use inference based on link measurements and routing information.
- Current research looks at techniques like principal component analysis, Kalman filtering, and incorporating additional data like access link measurements to improve estimates while reducing measurement needs. Hybrid methods combining analysis and some direct measurements are also promising.

January 22nd 2014
We are entering a data-rich era. Advanced computing, imaging, and sensing technologies enable scientists to study natural and physical phenomena at unprecedented precision, resulting in an explosive growth of data. The size of the collected information about the Web and mobile device users is expected to be even greater. To make sense and maximize utilization of such vast amounts of data for knowledge discovery and decision making, we need a new set of tools beyond conventional data mining and statistical analysis. One such a tool is visualization. I will present visualizations designed for gleaning insight from massive data and guiding complex data analysis tasks. I will show case studies using data from cyber/homeland security, large-scale scientific simulations, medicine, and sociological studies.

Netflow records network traffic metadata like source, destination, protocol, and duration of communications without inspecting traffic contents. This allows analysis of network usage patterns to identify bottlenecks, leaks, and attacks. While netflow reveals metadata, actual email contents remain private. Netflow is generated by network devices and collected by software that can provide aggregated traffic statistics or detailed records for forensic analysis. Placement of collection points is important to observe relevant traffic.

Corporate Open Source Anti-Patterns: A Decade LaterScyllaDB
A little over a decade ago, I gave a talk on corporate open source anti-patterns, vowing that I would return in ten years to give an update. Much has changed in the last decade: open source is pervasive in infrastructure software, with many companies (like our hosts!) having significant open source components from their inception. But just as open source has changed, the corporate anti-patterns around open source have changed too: where the challenges of the previous decade were all around how to open source existing products (and how to engage with existing communities), the challenges now seem to revolve around how to thrive as a business without betraying the community that made it one in the first place. Open source remains one of humanity's most important collective achievements and one that all companies should seek to engage with at some level; in this talk, we will describe the changes that open source has seen in the last decade, and provide updated guidance for corporations for ways not to do it!

Metadata Lakes for Next-Gen AI/ML - DatastratoZilliz
As data catalogs evolve to meet the growing and new demands of high-velocity, unstructured data, we see them taking a new shape as an emergent and flexible way to activate metadata for multiple uses. This talk discusses modern uses of metadata at the infrastructure level for AI-enablement in RAG pipelines in response to the new demands of the ecosystem. We will also discuss Apache (incubating) Gravitino and its open source-first approach to data cataloging across multi-cloud and geo-distributed architectures.
The "Zen" of Python Exemplars - OTel Community DayPaige Cruz
The Zen of Python states "There should be one-- and preferably only one --obvious way to do it." OpenTelemetry is the obvious choice for traces but bad news for Pythonistas when it comes to metrics because both Prometheus and OpenTelemetry offer compelling choices. Let's look at all of the ways you can tie metrics and traces together with exemplars whether you're working with OTel metrics, Prom metrics, Prom-turned-OTel metrics, or OTel-turned-Prom metrics!
