Application Scenarios
FunctionGraph is suitable for various scenarios, such as real-time file processing, real-time data stream processing, web & mobile application backends, and AI application.
Scenario 1: Event-Driven Applications
Services are executed in event-driven mode and resources are provisioned based on demands. Developers do not need to be concerned about service peaks or troughs. Idle resources are not billed, reducing O&M costs. Event-driven applications include file processing, image processing, live streaming/transcoding, real-time data stream processing, and IoT rule/event processing.
- Real-time file processing
When files are uploaded from a client to OBS, functions can be triggered to create image thumbnails in real time, convert video formats, aggregate and filter data files, or implement other file operations.
Advantages:
- FunctionGraph automatically allocates resources to run more function instances as the number of received requests increases.
- Files are uploaded to OBS to trigger file processing functions.
- You will be billed only for resources used to process files as needed (you are not billed for idle resources during lows in demand).
Scenario 2: Web Applications
Interconnect FunctionGraph with other cloud services or your VMs to quickly build highly available and scalable web & mobile backends. Web applications include mini programs, web pages/apps, chatbots, and Backends for Frontends (BFF).
Advantages:
- FunctionGraph ensures high reliability of website data using OBS, and high-availability of website logic using API Gateway.
- FunctionGraph automatically allocates resources to run more function instances as the number of received requests increases.
- You will be billed only for resources used to process files as needed (you are not billed for idle resources during lows in demand).
Scenario 3: AI Applications
Intelligence evolution requires various services to be integrated for quick rollout. These services include third-party service integration, AI inference, and license plate recognition.
Advantages:
- FunctionGraph works with EI services for text recognition and content moderation to suit a wide range of scenarios – make adjustments whenever you need as demands change.
- You only need to apply for related services and write service code without having to provision or manage servers.
- You will be billed only for function execution and used EI services without having to pay for idle resources when service demands are low.
