<p>Function Compute is an event-driven Serverless compute service. It can provide you with more flexible and reliable compute service while allowing you to focus on writing and uploading codes. Function Compute elastically provides compute resources in a fully managed manner with no fee incurred if you do not run the codes.</p>

Function Introduction

<p><strong>1.&nbsp;Function Overview</strong></p> <p>Function is the basic unit of system scheduling and operation. Supporting nodejs6, python2, python3 and java8, a function now could be created in two ways, online or local upload.</p> <p><strong>2.&nbsp;</strong><strong>Use Cases</strong></p> <p><strong>Multi- media processing</strong></p> <p>Functions could be written to zoom, clip or watermark pictures</p> <p><strong>IoT</strong></p> <p>Functions written in multiple languages could enable real-time processing of IoT messages.</p> <p>&nbsp;</p>


<p><strong>1.&nbsp;Trigger Overview</strong></p> <p>A trigger is an event that triggers the execution of a function. The OBS trigger and API GateWay trigger are currently available.</p> <p>&nbsp;</p> <p><strong>2.&nbsp;</strong><strong>Use Cases</strong></p> <p><strong>OBS trigger</strong></p> <p>If you intend to clip the avatars uploaded by users with the OBS service of Ping An Cloud, you can bind the trigger to the function by creating an OBS trigger and binding it to the corresponding bucket upload event, so as to realize expected functions.</p> <p><strong>API Gateway</strong></p> <p>Functions created through Function Compute service could be published to the API Gateway of Ping An Cloud to trigger the execution of the function by scheduling HTTP</p>

Product Advantages

<p><strong>Simple and convenient</strong></p> <p>Users can focus on the core code instead of concerning about related resources, which largely reduces the complexity of the service architecture. Without any manual configuration, the function elastically scales in real time based on the amount of business requests. The function platform could automatically schedule reasonable computing resources to cope with the peak demand in the changing application traffic.</p> <p>&nbsp;</p> <p><strong>Cost-saving</strong></p> <p>No charges incurred if users do not run the function. For some services that do not require long dwell time, it could largely reduce the resource costs. With service fees charged based on the number of requests and the runtime of the computing resources when executed, Function Compute does have obvious price advantage.</p> <p>&nbsp;</p> <p><strong>Easy management</strong></p> <p>The user only need to set the configuration via the function platform while the platform will automatically handle the deployment and operation, with separation guaranteed by exclusive containers and online one-click testing available.</p> <p>&nbsp;</p> <p><strong>Multiple triggers</strong></p> <p>Users can also trigger the functions through events generated by other cloud products in addition to the API Gateway.</p>
