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).

    For example, create two buckets in OBS, and build a function for compressing images uploaded to the specified bucket. For details, see Compressing Images.

  • Real-time data stream processing

    FunctionGraph works with DIS to process data streams in real time. FunctionGraph supports application activity tracking, sequential transaction processing, data stream analysis, data sorting, metric generation, log filtering, indexing, social media analysis, and IoT device data telemetry and metering.

    Advantages:

    • Data is collected by means of DIS streams to trigger data processing functions.
    • 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 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 CloudTable, 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.
