Challenges That teams face when trying to go faster Onboarding Process Application Runtime and Operations Distributed Systems @salaboy @vitalethomas

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

Dealing with State @salaboy @vitalethomas

Dealing with State @salaboy @vitalethomas

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

Event-Driven Scenarios @salaboy @vitalethomas

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

Complex Service Orchestration @salaboy @vitalethomas

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

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
