Benefits

Triggered by Events
Function is triggered by events, integrating JD Cloud OSS and API Gateway event source services, meeting demands in different application scenarios, and rapidly constructing applications and services.
No Need for Operation and Maintenance
Only business code is concerned, and there is no need to configure or manage server and other infrastructures, which greatly reduces the operation and maintenance cost.
Auto Scaling
Resources are automatically scheduled in real time to run function based on the number of concurrent requests to easily cope with business peak and trough.
Pay on Demand
Billing is done based on code call times and running time, with the duration metering granularity as low as hundreds of millisecond level.

Function running status and running logs are monitored to facilitate users to view function execution conditions.

Scenarios

Multi-media Content Analysis Processing

Multiple functions can be triggered by Object Storage Service upload events, to complete real-time image or file screening, unloading, creating thumbnails, converting video code as well as other processing and analysis. You can rapidly deploy complicated application and service through event trigger mechanism as well as construct an elastic and reliable backend system.

Serverless Backend Service

The backend is constructed through Function Service and API Gateway to verify and process API requests. Flexibly expandable architecture is constructed with Function Service, to easily create rich and personalized application experience.
