docker pull mcr.microsoft.com/windows/nanoserver:1909 docker pull mcr.microsoft.com/windows/servercore:1909 docker pull mcr.microsoft.com/windows:1909

*Current versions are ltsc2019 or 1909

• Smallest base layer available for Windows • 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) • Useful for automating builds and testing that rely on GUI APIs

. Container with .NET Core 3.1 runtime . Container with ASP.NET Core 3.1 . Container with .NET Core 3.1 SDK

docker pull mcr.microsoft.com/dotnet/core/runtime:3.1 docker pull mcr.microsoft.com/dotnet/core/aspnet:3.1 docker pull mcr.microsoft.com/dotnet/core/sdk:3.1

*Current .NET Core version is 3.1

Amazon ECS Amazon EKS

Amazon ECS Amazon EKS . Original AWS container . Managed Kubernetes service orchestration service introduced in 2018 . Supports Linux & Windows . Supports Linux & Windows . Just docker hosts . Master node + worker nodes . Supports Fargate . Supports Fargate “serverless “serverless containers” containers” . Launch using ECS CLI, AWS . Launch using eksctl CLI, or AWS .NET tool for ECS

. ECS Service Discovery . AWS App Mesh . Running containers in Elastic Beanstalk . Running containers on vanilla EC2

Operations and management Scaling

Provisioning and utilization Availability and fault tolerance

No servers to provision Scales with usage or manage

• Buy compute time in Free Tier 100 ms increments 1 million requests and 400,000 GBs of compute every month, every customer • Low request charge $0.0000002 per request (Ohio) • No hourly, daily, or monthly minimums • No per-device fees • No paying for idle

. 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)

. 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
