Alibaba Cloud Function Compute is a fully managed, event-driven compute service. Function Compute allows you to focus on writing and uploading code without having to manage infrastructure such as servers. Function Compute provides compute resources to run code flexibly and reliably. Function Compute provides free trial quota for the first-time users of Function Compute. New users who activate Function Compute can purchase a trial plan that is worth USD 24.13 free of charge. The validity period of the trial plan is three months. Each new user can purchase the trial plan only once. The trial plan includes 500,000 vCPU-seconds of vCPU, 1 million GB-seconds of memory, 4 million function invocations, and 100,000 GB-seconds of GPU memory.
Efficient and O&M-free
Function Compute frees you from purchasing servers, configuring load balancers and resource scaling, and other O&M operations so that you can focus on developing business logic and writing core code. This simplifies service construction and speeds up development and iteration.
Elastic and Highly Available
Function Compute automatically scales and mobilizes computing resources within milliseconds to handle traffic peaks. The reserved instance feature will provide enhanced performance and help you easily migrate online applications to Function Compute as well as avoid latency glitches caused by cold start.
Low Cost on Demand
Function Compute provides flexible billing methods for a variety of scenarios to save costs. The pay-as-you-go method charges you for instances you have used. The subscription method allows you to purchase computing powers based on estimated business load. The combination of pay-as-you-go and subscription instances effectively reduces costs.
Stable and Highly Reliable
Function Compute is deployed in distributed clusters that are located in multiple zones. If a natural disaster or power failure causes a zone to become unavailable, Function Compute automatically uses instances in another zone of the same region to run functions and ensure high service availability.
Function Compute associates event sources with triggers. An associated event source triggers a function to execute either synchronously or asynchronously when an event occurs. The change event is passed as an input parameter to the entry function.
Automatically triggers function execution when bucket objects are changed.
Passes change information as an input parameter to trigger function execution when table data is changed.
Log Service Trigger
Regularly obtains updated logs and triggers functions for custom log processing.
Writes functions to process messages published on topics in real time.
Writes functions for customized processing of CDN events such as refreshing and prefetching.
Receives and processes HTTP requests as well as returns HTTP responses.
Triggers function execution at a specified time point.
Route events to Function Compute by using event rules.
Kafka Connector trigger
Export data from a topic in the Kafka instance to a function.
Cloud Monitor trigger
Allows you to use monitoring events as event sources.
Export data to an HTTP function of Function Compute by using data outflow rules in the MQTT console.
Function Compute supports multiple programming languages and custom runtimes.
Node.js 6, Node.js 8, Node.js 10 and Node.js 12 are supported. Node.js runtimes configured with HTTP triggers are compatible with Express, a Node.js web application framework.
Python 2.7 and Python 3 are supported. Python runtimes configured with HTTP triggers comply with the WSGI specification.
Java 8 & Java 11 is supported. Java runtimes configured with HTTP triggers are based on the Servlet protocol.
PHP 7.2 is supported. PHP runtimes configured with HTTP triggers comply with the PSR standard (HTTP message interfaces).
.NET Core 2.1 is supported. C# runtimes configured with HTTP triggers comply with .NET Standard 2.0.
Customizes execution environments for multiple languages such as Go, Ruby, and Lua. Applications can be directly migrated to Function Compute by one click.
Custom Container Runtime
It offers developers a simpler experience and makes development and delivery more efficient.
Function Compute provides convenient development tools to help you smoothly develop, debug, and deploy applications in local environments.
An application development tool for you to create resources, debug locally, and install third-party dependencies online.
It is a command line tool provided by Alibaba Cloud Function Compute to help you manage resources in Function Compute.
Visual Studio Code Extensions
