Complex Event Flows in Distributed Systems

Event-driven architectures enable nicely decoupled microservices and are fundamental for decentralized data management. However, using peer-to-peer event chains to implement complex end-to-end logic crossing service boundaries can accidentally increase coupling. Extracting such business logic into dedicated services reduces coupling and allows to keep sight of larger-scale flows - without violating bounded contexts, harming service autonomy or introducing god services. Service boundaries get clearer and service APIs get smarter by focusing on their potentially long running nature. I will demonstrate how the new generation of lightweight and highly-scalable state machines ease the implementation of long running services. Based on my real-life experiences, I will share how to handle complex logic and flows which require proper reactions on failures, timeouts and compensating actions and I provide guidance backed by code examples to illustrate alternative approaches.

Designing Events-First Microservices

In this talk, we will explore the nature of events, what it means to be event-driven, and how we can unleash the power of events and commands by applying an events-first domain-driven design to microservices-based architectures.
We will start by developing a solid theoretical understanding of how to design systems of event-driven microservices. Then we will discuss the practical tools and techniques you can use to reap the most benefit from that design, as well as, most importantly, what to avoid along the way.
We’ll discuss how an events-first design approach to building microservices can improve the following characteristics over competing techniques:
  • increase certainty
  • increase resilience
  • increase scalability
  • increase traceability
  • increase loose coupling
  • reduce risk

Skeptics should definitely attend.

Debugging Microservices: How Google SREs Resolve Outages

When using tens or hundreds of microservices to provide an application's critical functionality, diagnosing what interaction between components is causing an outage can be challenging. Engineers spend a lot of time building dashboards to improve monitoring but still spend a lot of time trying to figure out what’s going on and how to fix it when they get paged. Building more dashboards isn’t the solution; using dynamic query evaluation and integrating tracing is. Learn how SREs discover and debug problems at Google during outages, and hear real stories about our experiences.

No Microservice Is an Island

You don't deploy a single microservice. The journey to microservice architecture involves more than how code is written or applications are packaged. It's about creating an interconnected ecosystem that keeps things running. Infrastructure and tools have only grown in importance as microservices have emerged as a dominant architecture pattern. Deploying, scaling, and monitoring are more important for microservices than they ever were before. Attendees will leave this session knowing the basic infrastructure and tooling needs for microservices to be successful.

Design Microservice Architectures the Right Way

Learn from first hand, deep experience, the most critical decisions we face in building successful microservice architectures: how to think about the tradeoffs that impact the productivity of our teams and the quality of our software. In particular, understand how to avoid creating an architecture that eventually (and sometimes quickly) paralyzes our ability to execute. This talk highlights specific key decisions that very directly impact the quality and maintainability of a micro service architecture, covering infrastructure, continuous deployment, communication, event streaming, language choice and more, all to ensure that our teams and systems remain productive as we scale.
