Overview
Service Overview
Cloud Functions is a serverless computing-based FaaS (Function as a Service) that lets you easily run function-based applications without provisioning servers. Users do not need to hassle with managing servers or containers for scaling and can focus on writing code and deploying applications.
Features
- Easy and convenient development environment: Developers can easily create Function resources that connect to events across multiple environments using a Code Editor suitable for the selected runtime, and can write and invoke code with ease.
- Serverless Computing: You can use a serverless code execution service for development in the Samsung Cloud Platform environment. * The resources required to invoke and run function-based applications are allocated and managed by the Samsung Cloud Platform according to the scale of execution.
- Efficient Cost Management: The invoked Function aggregates usage (total number of calls, total execution time) and charges based on the time actually used to run the application. * Functions with low usage can have the Cloud Functions scaler adjusted to a scale-to-zero state, so they do not consume resources, enabling efficient cost management.

Caution
Runtime scheduled for deprecation
- For Runtime versions scheduled for deprecation, technical support is expected to end within 60 days (End of Technical Support) (detailed schedule will be announced on the console).
- If technical support for a Runtime version ends, security patches and updates will no longer be applied to that Runtime version.
- Functions that have already been created can be used indefinitely without a call time limit, but they cannot be modified.
- We do not guarantee against bugs, errors, defects, or vulnerabilities that arise in Runtime versions for which technical support has ended.
- It is recommended to safely use functions slated for deprecation by migrating to a different version of the function.
