Taming Configuration Complexity Made Fun with CUE

Configuration has become the number one complexity problem to solve in infrastructure and beyond. Configuration is in more places than people imagine. Every part of your tech stack—databases, apps, schemas, services, workflows, policy, models, networking—must be configured. Not only that, there are dependencies between these configurations. With cloud, multi cloud, IoT, and edge computing, the number of things to configure within growing systems has exploded. The consequences of getting configuration wrong have only worsened over time. 

We are in the middle of a major shift where configuration is becoming a first-class citizen across your stack. New engineering roles dedicated to solving configuration problems have emerged: Platform, Site Reliability, Resilience, Observability, Data, “DevOps” and “YAML” engineers all deal with easing configuration toil. There are many tools and approaches that aim to help developers deal with growing configuration complexity: Configuration Management, Infrastructure as Code, GitOps, Policy as Code, and finally, Infrastructure as Data. The industry needs something to unify all these roles, approaches, and challenges, and break down configuration silos. CUE (cuelang.org) does exactly that.  

In this presentation, you will hear:

  • hard-won insights and experiences of configuration at scale, culminating in the design of CUE,

  • how configuration can go wrong,

  • the need for testing and validation,

  • how CUE is paving the way for a holistic approach to configuration via a language, tooling, and APIs that support a vibrant configuration ecosystem,

  • where the magic happens for data, schema, validation, and templating, in real-world examples,

  • how CUE can adapt to existing systems and tooling, allowing for a phased approach to grappling with configuration,

  • the new generation of projects, companies and technologies adopting CUE,

  • what the future of Configuration Engineering looks like.

Programming Your Policies

Tuesday Dec 6 / 11:20AM PST

Software is eating the world, and this talk is about how it is coming to eat the world of policy. I will talk about why this is happening, what the business drivers are, and how it affects developers and compliance and security departments, and the cultural and communication changes there.

Sprinkling eBPF Onto Your Observability

Tuesday Dec 6 / 10:10AM PST

When talking about Observability in 2022 there is no way around eBPF. However, eBPF is often seen as magic dust that can be sprinkled into infrastructure and magically do anything, when the reality is much more complicated.
