Are you done yet? Mastering long-running processes in modern architectures
#1about 4 minutes
Explaining synchronous and asynchronous communication with metaphors
A pizza ordering metaphor illustrates the difference between synchronous blocking communication like a phone call and asynchronous non-blocking communication like an email.
#2about 7 minutes
Defining long-running processes and business reasons for waiting
Long-running processes are defined by periods of waiting, driven by business needs like human tasks, response delays, or mitigating buyer's remorse.
#3about 4 minutes
The hidden complexity of building stateful applications
Implementing stateful, long-running logic with simple database columns leads to accidental complexity around visibility, escalations, versioning, and reliability.
#4about 10 minutes
A live demo of a workflow engine with spring boot
A practical demonstration shows how to use a workflow engine like Camunda with Spring Boot to model, execute, and monitor a customer onboarding process.
#5about 9 minutes
Using long-running patterns to build resilient systems
Failures in distributed systems, such as an unavailable service during an airline check-in, necessitate long-running retry patterns to create a resilient architecture.
#6about 6 minutes
Implementing safe retries with idempotency and compensation
Safely retrying operations in a distributed system requires idempotent APIs to prevent duplicate actions and compensation logic to clean up after ultimate failures.
#7about 6 minutes
Designing clean service boundaries with orchestration
Empowering individual services to handle their own long-running logic, like payment retries, leads to cleaner service boundaries and avoids creating monolithic god services.
#8about 4 minutes
Why graphical models are powerful tools for developers
Graphical models like BPMN serve as living documentation, facilitate communication between business and technical teams, and provide crucial operational visibility.
#9about 9 minutes
Q&A on Camunda, implementation trade-offs, and scale
