No built-in i18n for functions

Responses can be localized by function logic

Works with multilingual IBM Cloud services

Event payloads can carry language-specific data

Focus is infrastructure and execution, not translation

Accessible via CLI, web console, or REST API

Functions reachable via HTTP triggers

Logs and metrics accessible for debugging

Namespace isolation supports multi-tenant deployments

Integration with IBM Cloud services for event sources

No dedicated UI for functions; dashboard provides management and analytics

Integrates with IBM Cloud web console

Focus is backend execution and event processing

Function output typically JSON or HTTP response

Sequences can be visualized in console

Functions are stateless

Persistent data managed externally (DBs, Object Storage)

Environment variables provide configuration

Sequences maintain temporary payload between actions

Isolation ensures no shared global state

Input from HTTP, cloud events, or messaging systems

Output returned via HTTP or downstream services

Supports JSON, text, and binary payloads

Environment variables and secrets for sensitive data

Logs stored and accessible for monitoring
