1. Mauricio Salatino & Thomas Vitale KubeCon+CloudNativeCon Europe Mar 21st, 2024 Unlocking New Platform Experiences with Open Interfaces @vitalethomas @salaboy
2. Challenges That teams face when trying to go faster Onboarding Process Application Runtime and Operations Distributed Systems @salaboy @vitalethomas
3. Let’s Start with a Demo Polyglot Distributed System Based on https://github.com/dockersamples/example-voting-app @salaboy @vitalethomas

6. Onboarding Process Risk of complexity and high cognitive load for developers How to bootstrap a new project? Containerization? Is the developer’s responsibility? Local development work fl ow requiring Kubernetes? Di ff erent con fi guration between local and production? What’s the overall cognitive load for developers using the platform? @salaboy @vitalethomas
7. Onboarding Process @salaboy @vitalethomas Risk of complexity and high cognitive load for developers
8. Dealing with State @salaboy @vitalethomas
9. Dealing with State @salaboy @vitalethomas
10. Dealing with State Challenges * Do you run infrastructure like Redis and PostgreSQL locally for development? Do you run them using Docker Compose? * We introduced coupling between the apps and the environment (the infrastructure that they need to run) * Is Redis and PostgreSQL for local development the same versions as the one running in Production? * How are clients/drivers con fi gured? Di ff erent con fi gurations lead to applications behaving unexpectedly di ff erent @salaboy @vitalethomas
11. Event-Driven Scenarios @salaboy @vitalethomas
12. Event-Driven Scenarios Challenges * Event-Driven interactions can enable multiple integrations, platforms should promote and support complex event interactions * But, event-driven applications involve several consumers and producers. Coupling is introduced between the services and the infrastructure * Message Brokers like Kafka, RabbitMQ or cloud provider speci fi c services are complex to set up and miscon fi gurations can cause the entire application to stop working @salaboy @vitalethomas
13. Complex Service Orchestration @salaboy @vitalethomas
14. Complex Service Orchestrations * Sometimes we need more than just calling X services in a sequence * We want to make sure that: * If things fail we have a backup plan like: custom retries, circuit breakers and domain-speci fi c logic hooks * Support for long running and stateful interactions, for example waiting for a human input that might be on holidays * That we have compensation logic to undo operations @salaboy @vitalethomas
15. Application Runtime and Operations The Complexity of Going to Production How to rollout new deployments safely? Does the app have to be platform- aware? Autoscaling? Can we scale from zero? Can you infer the state of the app from its output signals? How to manage and operate a platform? @salaboy @vitalethomas

Flux Continuous deployment via GitOps and RegistryOps. OpenTelemetry Uni fi ed APIs and protocols for observability signals (logs, metrics, traces…).
31. Takeaways * APIs, standards and open source projects: help you to protect your platform investments * Speedy Onboarding process: simplify and reduce cognitive load from new team members * Out of the Box Cloud-Native patterns: abstract away complexity to reduce cross-environment differences * Smooth Operations: optimise for your use cases, there is no silver bullet @salaboy @vitalethomas
