Changing how 10 people work is difficult. Changing how 5,000 is near impossible. If you're trying to move beyond your initial success at transforming how your organization builds and runs software, you're experienced this problem. We'll look at common challenges and cover tactics to address them.

Changing how 10 people work is difficult, changing how 100 work is very difficult. And, barring Planck's principle, changing how 5,000 or more people work is, typically, impossible. When it comes to improving how large organizations build, release, and run software, scaling to thousands of people is the real challenge. If you're trying to move beyond your initial success at transforming how your organization builds and runs software, you've experienced this scaling challenge. Thankfully, most of the problems in this challenge are common challenges. Though you may feel cursed and alone, in our experience talking with hundreds of organizations, most of the problems are the same. This talk will look at several of these common challenges and cover tactics to address them. Part of applying a tactic successfully is understanding why the challenge exists in the first place, which the talk starts with.

In rapidly expanding cloud-native ecosystem, managing distributed architectures feels like navigating stormy seas with waves of telemetry data. Yet this data can offer vital insights to sail smoothly. This session will explore strategies to avoid drowning, improving DevEx, and more.

The cloud-native ecosystem has grown exponentially in the last few years, as has the complexity of the distributed architectures being built. In a context where keeping up with technology requires a substantial amount of computational power and data, monitoring our cloud-native applications has become a constant struggle against the storm. The ever-increasing volume of traces, metrics, events, and logs generated by our systems is a double-edged sword: on one hand, if not managed correctly, becoming a distraction from needed insights. On the other hand, if approached with care and thought, providing organizations the chance to sail calm cloud-native seas. In this session, we will discover how to avoid drowning in the sea of monitoring data, instead understanding how to provide insights while using only what is needed. We will explore the emerging scenarios on the horizon, abandoning the oars and testing the waters of artificial intelligence as it applies to our observability use cases.

GenAI has gone from generally available, novel technology to widely adopted in a matter of months. Most engineering organizations are now using GenAI to generate code, write tests, and assist in code reviews. New code is becoming dirt cheap to write - but our delivery pipelines remain miserably unprepared for the tsunami of new code flowing at a much more rapid pace.

Our current pipelines need a hard reset to prepare us for the GenAI revolution - and engineering managers need to get started TODAY.

This talk will dive into where GenAI is starting to break down our delivery pipelines. While scaling CI/CD is easy, and we can always add a few more workers, scaling the humans in the process is the hard part. This talk will demonstrate how massive amounts of new machine-generated code will impact our pipelines, in ways that will require either greater headcount, or smarter, automated pipelines. You’ll come away with ideas for how to modernize your delivery pipeline so you can fully embrace the GenAI revolution.

In today's cloud-native environments, Infrastructure as Code (IaC) has become the foundation upon which modern infrastructure is built and maintained. This keynote explores the vital role IaC plays in ensuring seamless, scalable operations, with a special focus on how SRE teams can enforce best practices without falling into the trap of bottlenecks and manual interventions.

Drawing an analogy to the engineering of a dam, we will dive into how SRE teams can supervise IaC deployments effectively—just as a dam controls water flow—by unifying deployment strategies, ensuring consistency, and avoiding system leaks. The key to maintaining control lies in formatting IaC into reusable blueprints that promote cloud-agnostic solutions, while preserving critical data streams between these blueprints.

But supervision alone isn't enough. To truly prevent leaks, we must introduce and enforce policies that guide deployments, monitor changes, and ensure compliance. By applying these policies at every stage of the deployment pipeline and carefully monitoring each change, SRE teams can create a safe, reliable stream of infrastructure updates. With the right tools and a culture that avoids bottleneck centralization, the potential for scale becomes limitless.

This keynote will unpack how to implement seamless IaC policy enforcement, ensuring secure, scalable infrastructure that can meet the demands of any organization, without the need for constant firefighting.
