Speaking

Tracking a request’s flow across different components in distributed systems is essential. With the rise of microservices, their importance has risen to critical levels. Some proprietary tools for tracking have been used already: Jaeger and Zipkin naturally come to mind. Observability is built on three pillars: logging, metrics, and tracing. OpenTelemetry is a joint effort to bring an open standard to them. Jaeger and Zipkin joined the effort so that they are now OpenTelemetry compatible. In this talk, I’ll describe the above in more detail and showcase a (simple) use case to demo how you could benefit from OpenTelemetry in your distributed architecture.

All mature tech stacks nowadays offer infrastructure-related capabilities, either a standard lib or in 3rd-party libraries, e.g., rate-limiting and authorization. While it’s great to have such features, it’s impossible to audit them easily. You’d need to be familiar with the stack and dive deep into the code. This approach just doesn’t scale, A well-designed system keeps the right feature at the right place. In this talk, I’ll go through all steps toward making your system more easily auditable. I’ll use the authorization of a security policy as an example and start from a regular Spring Boot project with Spring Security. I’ll then move step-by-step, introducing the Open Policy Agent (OPA) and the Apache APISIX API Gateway. The end result will have moved all authorization details buried in the code in a readable accessible place.

Il est essentiel de suivre le parcours d’une requête à travers les différents composants d’un système distribué. Avec l’essor des microservices, cette fonctionnalité a atteint un niveau de criticité comme jamais auparant. Certains outils propriétaires de suivi vous sont peut-être connus : Jaeger et Zipkin viennent naturellement à l’esprit. L’observabilité repose sur trois piliers : la journalisation, les métriques et le traçage. OpenTelemetry est un effort conjoint visant à mettre en place un standard ouvert pour ces trois piliers. Jaeger et Zipkin se sont joints à cet effort et sont maintenant compatibles avec OpenTelemetry. Dans cet exposé, je décrirai plus en détail ce qui précède et je présenterai un cas d’utilisation (simple) pour démontrer comment vous pourriez bénéficier des traces OpenTelemetry dans votre architecture distribuée.

It’s been said that GitHub is a developer’s CV. Just a quick look at your commit history and recruiters know all about you. There are a couple of issues with this approach. Most companies don’t even publish their source code under an Open Source license. If you work for one of them, and if you’re not a rabid Open Source developer, then it’s obviously not helpful. Recently, GitHub allowed some degree of customization of one’s profile. So, even if your commit history has more white than green, you can provide a good entry-point for potential employers. But it’s only as good as the effort you put in it, and it might decay fast. Yet, with a bit of work, and the help of automation tools (such as GitHub Actions), you can provide an always up-to-date profile. In this talk, I’ll present you how to do it, using my own setup as an example.

When you publish your first HTTP API, you’re more focused on short-term issues than planning for the future. However, chances are you’ll be successful, and you’ll hit the wall. How do you evolve your API without breaking the contract with your existing users? In this talk, I’ll first show you some tips and tricks to achieve that: moving your endpoints, deprecating them, monitoring who’s using them, and letting users know about the new endpoints. The talk is demo-based, and I’ll use the Apache APISIX project for it.

Micro services are ubiquitous. However, most companies that implement micro services do not reap their full benefits - at best. At worst, it’s an epic failure. There are reasons for micro services: independent deployment of business capabilities. However, the unspoken assumption is that you need to deploy all capabilities all the time. My experience has shown me that it’s plain wrong. Some capabilities need frequent deployment, while some are much more stable. In "the past", we used Rule Engines to allow updating business rules without deployment. While it solved the problem, this approach had issues. Between introducing a Rule Engine and migrating your complete system to micro services, I believe that there’s a middle path, and that this path is Function-as-a-Service. In this talk, I’ll detail every point I’ve made above, and show how one can use Serverless to pragmatically design a system that allows deploying as often as you need.

One of the web architect’s main challenges is to tackle image optimization. The age-old approach is to deliberately create size variants of a single image to deliver the best user experience. It was a time-consuming task, which can be marginally improved with Machine Learning. In this session, I’ll offer a new approach that should both avoid this process and cut storage costs. Join me for practical insights into reducing expenses without compromising web performance.

Die Entwicklung einer vollwertigen API braucht Ressourcen, sowohl Zeit als auch Geld. Ihr müsst über das Modell, das Design, die REST-Grundsätze usw. nachdenken, ohne eine einzige Zeile Code zu schreiben. Meistens weiß man nicht, ob es sich lohnt: Man möchte ein Minimum Viable Product anbieten und von dort aus iterieren. In diesem Vortrag möchte ich euch zeigen, wie ihr das mit PostgreSQL, PostgREST und Apache APISIX erreichen könnt.

On dit que les données sont le nouveau pétrole. Pour connecter des systèmes hétérogènes, le standard de facto est est les APIs HTTP. Mais aucune entreprise ne se permet d'exposer directement son système d'information à l'extérieur. Vous avez besoin d'un point d'entrée central pour gérer les problématiques transversales comme l'authentification et une liste noire d'adresses IP, mais aussi la limitation du débit et le déploiement canari. Dans cet atelier, nous utiliserons Apache APISIX (sur Docker) pour montrer quelques capacités qui peuvent aider votre système d'information à faire face aux défis introduits par les APIs. * Routage de vos appels vers le bon Upstream * Les abstractions disponibles : Route, Upstream, Service * Le tableau de bord Apache APISIX * Configurer APISIX avec le tableau de bord * Configurer APISIX avec la ligne de commande * Surveillance d'APISIX * Introduction au développement de plugins en Lua
