API Design

Caching

Storing frequently accessed data in a fast-access storage layer to reduce latency and improve performance.

Idempotency

The property where an operation produces the same result regardless of how many times it is executed.

Rate Limiting

A technique for controlling the number of requests a client can make to an API within a specified time period.

Circuit Breaker Pattern

A design pattern that prevents cascading failures by stopping calls to a failing service temporarily.

Concurrency

The ability of a system to handle multiple tasks simultaneously by interleaving their execution.

Parallelism

Five principles of object-oriented design promoting maintainable, flexible, and understandable code.

Automatic memory management that reclaims memory occupied by objects no longer referenced by the program.

A deployment strategy where changes are gradually rolled out to a small subset of users before full deployment.

A tool that automates the process of installing, upgrading, configuring, and removing software packages.

A deployment strategy using two identical production environments to achieve zero-downtime releases.

A visual workflow management method that limits work in progress and optimises the flow of tasks through a system.
