The State of SQL-Based Observability

by Ryadh Dahimene

Many successful paradigms in engineering and computer science are the result of two distinct approaches colliding with each other, leading to broader and more powerful applications. In this talk, we’ll look at the parallel backgrounds of two established paradigms: SQL and Observability.

We’ll be tracing back the history of both paradigms. How they managed to avoid each other despite SQL being the lingua franca of data manipulation, and how the industry standardization, fuelled by open-source innovation, has now propelled SQL back into the game as an observability language. We’ll also highlight case studies and benchmark results to provide the necessary elements for the attendee to answer a simple question: is Sql-based observability applicable to my use case? highlighting also the current limitations of this approach and leaving the conclusions for the attendees to draw.

Generative AI: bliss or miss?

by Diana Todea

GenAI is not a brand new technology yet it has become a hot topic in the last couple of years. As many organisations are adopting it within different business cases, SREs and DevOps engineers have a great deal to say about its best use cases.

This talk puts GenAI on the DevOps map, and deep dives into the GenAI applications within the DevOps/SRE realm.

In this talk, I will revisit concepts and technologies linked to GenAI such as transformers, LLMs and RAG and see them applied into observability, in particular in the shape of the AI Assistant and focus on some use cases for DevOps engineers. Whether GenAI is really a must try technology, we will understand by the end of this talk.

A Tale of Tail Latency: Understanding Kubernetes CPU Requests and Limits For Sustainability and Profit

by Ara Pulido

When deploying an application to Kubernetes, each container in a pod should define CPU requests and limits. It is more commonly understood how CPU requests affect the scheduling of your pod and the future pods in the same node. But outside scheduling, CPU requests and limits have some effects on how your containers are created and can heavily impact their performance and their energy footprint.

In this talk we will help clarify some misconceptions about CPU requests and limits by explaining, in a developer friendly way, how they translate to some Linux internals. We will offer some quick tips on how to understand those effects, minimise them, and select good values to reduce your application energy footprint while ensuring its performance.

Scaling: from 0 to 25 million users

by Josip Stuhli

A story of how our infrastructure evolved over time to accommodate an increasing number of users - from on-premise to cloud and back down.

How does one make an infrastructure to handle more than a couple of users? How do you go from 100 to 1000 to 100,000 to tens of millions? What happens when due to popular demand hundreds of thousands of users hit your servers at the same time?

I'll tell you a story of how a small team of people managed to move software and services from one server to two, and then to dozens on cloud and then back to on-premise. What we encountered on the way, where we failed, and how we solved it.
