How readily a relevant audience can discover, understand, and use a page across search and answer experiences.
Read definitionSearch and development glossary
A practical glossary for search, content, and product teams.
API
An API is an interface and set of rules through which software components request data or actions from one another. Its contract defines operations, inputs, outputs and errors; documentation explains how to use it.
Read definitionAPI endpoint
An API endpoint is a specific address and method through which a client accesses one operation, such as `GET /users`. Its contract defines accepted parameters and response behavior.
Read definitionAuthentication
Authentication verifies who a user or service is, for example by checking a password or signed token. It does not decide what that identity is allowed to do.
Read definitionAuthorization
Authorization decides which resources and actions an authenticated identity may use. Keep it separate from authentication: a valid login does not automatically grant every permission.
Read definitionCI/CD
Continuous integration (CI) automatically builds and checks code changes. Continuous delivery keeps verified changes ready for release, which may require approval; continuous deployment automatically releases verified changes to production.
Read definitionContainer
A container is a running, isolated instance created from an image. It shares the host OS kernel, unlike a virtual machine with a guest OS; persistent data is usually stored outside the image.
Read definitionContainer image
A container image is an immutable, layered package used to create containers. It contains an application and its runtime dependencies; persistent data should usually live outside the image.
Read definitionEnvironment variable
An environment variable is a named value supplied to a process at runtime, often for configuration. Do not put secrets in client-side bundles or expose them in logs.
Read definitionUnit test
A unit test checks a small unit of code in isolation, such as a function, against expected results. Dependencies are often replaced with controlled test doubles.
