Function Compute (2.0):Overview

Background

Function Compute invokes your function in an execution environment. The execution environment provides a secure and isolated runtime environment that manages the resources required to run your function. If an execution environment from a previous invocation is available, Function Compute reuses the execution environment. Otherwise, Function Compute creates a new execution environment.

Each runtime of Function Compute is based on a specific Linux distribution. Debian 9 (Stretch) and Debian 10 (Buster) are supported. A runtime can use a single version of a language, multiple versions of a language, or multiple languages. When a version of a language reaches the end of life, runtimes for the version and language framework are deprecated.

Supported runtimes

Node.js

Python

PHP

Java

.NET

Go

Custom runtime

Runtime deprecation policy

With the iteration of runtime versions, Function Compute stops maintaining specific runtimes and no longer provides technical support or security updates for these runtimes. The deprecation of a runtime is divided into two phases.

• Phase 1

  You can no longer create functions that use the runtime, but you can still execute and update existing functions that use the runtime.

• Phase 2

  You can no longer create or update functions that use the runtime, but you can still execute the existing functions that use the runtime.

The following table lists the deprecation plans for runtimes in Function Compute. For runtimes that are not listed in the table, no deprecation plans have been made yet. Function Compute notifies you by email or internal messages if you have functions that use a runtime that is to be deprecated in the next 60 days.
