Description
Choreography is a concept that describes how systems or components communicate and interact with each other. It enables the decentralization of control and promotes flexible, reactive architectures.
✔Benefits
- Increased flexibility in system architecture.
- Better maintainability of components.
- Easier integration of new features.
✖Limitations
- Can become complicated when many systems are involved.
- Requires well-defined interfaces.
- More effort in synchronization.
Trade-offs
Metrics
- Response Time
The time it takes for the system to respond to requests.
- Error Rate
The percentage of erroneous requests in the system.
- System Availability
The percentage of time the system is operational.
Examples & implementations
Project A
A project using microservices to scale the application.
Project B
A system for real-time data processing for online transactions.
Project C
An automation tool for business processes in a large organization.
Implementation steps
1
Design the system architecture.
2
Define the API interfaces.
3
Implement and test components.
