Compute > Cloud Functions > Overview

Users can write codes by function unit. Functions defined on a specific event are automatically executed, processing the required tasks. Without server management or infrastructure configuration, you can focus only on application logic.

Features

• Cost-effectiveness
  • Save money with pay-as-you-go pricing.
  • You can reduce management cost as it allocates resources only when necessary.
  • Scale up and down automatically on demand to keep operating efficiently.
• Rapid development and deployment
  • Focus on the core business logic.
  • Shorten the development speed by reducing the burden of DevOps operation.
• Flexibility and scalability
  • Support for multiple languages and runtimes.
  • The event-based architecture is versatile.

Main features

• We offer multiple languages (environments).
• The code editor makes you write simple function unit code.
• Provide an HTTPS Endpoint as standard to perform the function.
• Iterate the function at regular cycles.

Two modes available

• Pool Manager
• New Deployment

Pool Manager

• Instances are created and use resources only when the function is performed.
• If the function is not performed for a certain period, instances disappear, and the resource usage becomes 0.
• Use it only when the number of requests is small to perform the function and event occurs.

New Deployment

• Once functions are created, instances are created, keeping a certain amount of resources being used.
• Instances are kept to reduce response latency.
• Use it when the number of requests is large to perform the function and a quick response is needed.

Supported languages

Trigger

• HTTP Trigger
  • Basic (support GET, POST)
• Timer Trigger
  • You can add it in the cron expression form.
• API Gateway Trigger
  • It can be integrated with the API Gateway service.
