• Only 64-bit applications

• No graphical applications

• .NET Core

• Only PowerShell Core is available

• PowerShell Core not included by default

(version 1709 onwards)

• Minimal installation of Windows Server 2016/2019

• Windows PowerShell

• .NET Core & .NET Framework

• No Widows Shell Desktop

• Great for migrating existing Windows applications to

containers

• Full installation of Windows Server 2019

• Windows PowerShell

• .NET Core & .NET Framework

• Widows Shell Desktop APIs including DirectX

(but you can’t RDP into it)

Lambda layers

Centrally manage code and data that is shared across multiple functions.

Keep deployment packages small, and avoid errors that can occur when you install

and package dependencies with your function code.

A layer is a ZIP archive that contains libraries, a custom runtime, or other

dependencies.

.NET support for Lambda layers is enabled by the

Amazon.Lambda.Tools NuGet package (.NET Core Global Tool)

Allows you to create and inspect layers, and deploy layer-aware functions

Using layers enables you to pre-JIT the platform-agnostic MSIL into native machine

code, significantly reducing cold-start times! (Requires publishing the layer from an

Amazon Linux AMI EC2 instance)

Custom Runtime support

Use your own runtime within a Lambda function.

Craft and use languages and custom runtimes not provided by AWS

Distribute custom runtimes as Layers if desired

Opens up Lambda to almost any language or customized runtime

environment

.NET support for custom runtimes is enabled by the

Amazon.Lambda.RuntimeSupport NuGet package

Allows you to specify custom .NET Core versions (for 3.0, preview, etc)

AWS also provides reference implementations for C++ and Rust
