Technology foundations
A neutral overview of architecture patterns used in modern platforms: data pipelines, services, logging, and reliability practices.

System layers
Most platforms are composed of multiple layers: client applications, APIs, service logic, data storage, and monitoring.
Understanding layers helps explain why performance and behavior can vary across regions, devices, or network conditions.
- Clients (web/mobile) communicate with APIs
- Services apply rules and validations
- Storage retains state; logs capture events
- Monitoring detects anomalies and incidents
Reliability and incident handling
Well-run systems plan for failure. They use staged rollouts, feature flags, and rollback mechanisms to reduce risk.
- Staged deployments and canary releases
- Observability: metrics, logs, traces
- Clear incident response processes
Transparency in documentation
Clear documentation reduces misunderstanding and supports safer user interactions. It should explain what the system does and does not do.
- Readable policies and terms
- Change logs for major updates
- Support and reporting channels
