Internationalization
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
Accessibility
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
Ui Styling
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
State Management
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
Data Management
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
Frequently Asked Questions about Ibm-cloud-functions
What is Ibm-cloud-functions?
IBM Cloud Functions is a serverless platform based on Apache OpenWhisk that allows developers to run code in response to events without managing infrastructure. It supports multiple runtimes and integrates with IBM Cloud services for event-driven applications.
What are the primary use cases for Ibm-cloud-functions?
