AWS Innovate 2016

1. Moving Microsoft .NET applications
one container at a time
• Daniel Zoltak, Solutions Architect, Amazon Web Services

2. Agenda
• A brief history of .NET
• Explore developer experience outside of Windows OS
• Demystify .NET in Docker and Containers
• .NET & Docker hands on demos
• Your AWS service adoption options

3. Let’s talk about Microsoft
.NET

4. v
Multi Language VM – .NET
(Common Language Runtime)
• Launched with support of 23 programming languages
• Languages such as Pascal, Haskel, Cobol, VB.NET, C#, J#/Java,
etc
• Designed to abstract Windows 32 API & COM
• Simplification of Windows development which was a “black art” at
the time
• Visual Studio .NET IDE launched as the primary
developer experience

5. v
.NET & Open Source Efforts
• MSFT Shared Sourced & ECMA standardized .NET
• Shared Source Common Language Infrastructure (SSCLI)
codenamed Rotor
• Not licensed to be used commercially
• It didn’t go very far outside of academia and research
• Then Mono came along…
• Took the great ideas of .NET CLR and Rotor and rebuilt it from
scratch
• Made it multi-platform (OSX and Linux - and Windows)

6. v
.NET & Open Source Efforts (2)
• Microsoft decided to go full Open Source with .NET
Runtime
• Announced and Released .NET Core CLR
• Cross platform run-time support for .NET applications + ASP.NET
Core
• Docker support announced for Windows Developers
• MSFT and 3rd Party Projects at dotnetfoundation.org
• Aims to take open source community projects to the next level

7. v
ASP.NET Core & CoreCLR Cross Platform
• Premiere developer experience on Windows (still)
• Predominantly GUI and now more command line centric
• Now developers can edit in Visual Studio Code,
Sublime, Emacs with intellisense and tools extensions
• Learn more from http://www.omnisharp.net
• Command Line experience same across all platforms
• Windows, OSX and Linux variants
• Enables true automation, continuous integration + delivery (CI/CD)

8. v
Visual Studio Code on Mac OSX
Visual Studio Code
A mini-Visual Studio IDE development environment for cross Platform
development

9. v
Demo Video Insert
• Insert Demo here: Innovate - Moving MSFT Apps in Docker - Demo 1
• Duration 00.05.57

10. v
Your .NET Framework & Runtime Options
• (Classic) .NET Framework – Windows only and feature
complete
• .NET Core CLR – New Microsoft cross platform runtime
• Feature Complete now in Stabilization Phase (RC2)
• Linux and OSX in-progress RC2 builds
• Available on GitHub: https://github.com/dotnet/coreclr
• Mono – 3rd party cross platform and open source
• Similar APIs to .NET Framework with high level of compatibility

11. v
Switching .NET Environments
• DNVM can be used to manage version of the .NET
execution environments on your system

12. v
Developer Experience

13. v• Apiport – .NET Portability Analyzer
• Source available on Git: https://github.com/Microsoft/apiport
• Console and Visual Studio Versions: https://dotnet.github.io/porting/
• MSDN: Porting MSBuild to .NET Core: http://bit.ly/1QyFVaX
Porting to .NET Core

14. v
What’s the difference between Runtimes?
(And why should I care?)
• .NET Core - No longer large monolithic core Framework libraries requiring whole
assembly redeployments – instead lots of little packages are used
• Using popular NuGet package format used - extend the application & runtime support
libraries
• Some common (60+) projects at https://github.com/aspnet
System.Core.File
System.Core.IO
System.Web.Session
System.Web.SignalR
MyApp.Service MyApp.Libs1
MyApp.LibsNMyApp.API
System.Web
System.Core
MyApp.Everything

15. Let’s talk about Docker &
Containers
☐✔

16. v
How is Docker different from VMs?
• Containers have similar resource isolation and allocation benefits as virtual
machines but a different architectural approach allows them to be much more
portable, light-weight and efficient.

17. v
About Containers…
• Include the application and all of its dependencies
• Share the kernel with other running containers
• Run as an isolated process in user space on the host operating system
• Not tied to any specific infrastructure – Docker containers run on any
computer, on any infrastructure such as the AWS cloud
• Popular in Linux world and now available to .NET developers (thank
MSFT)

18. v
Why It Matters to .NET Applications?
• For Existing Applications
• Move your existing .NET applications into highly portable self-sufficient
containers
• Extend the life of applications or merely renovate them
• For Green Field Applications
• Develop brand new applications using .NET/ASP.NET
• Develop via Visual Studio (Windows) or Visual Studio Code (OSX/Linux) or
CLI
• Press a button or run a script to deploy it into Docker on AWS
• Bring your applications into a modern and agile (CI/CD) DevOps world
• Move into AWS – gain agility, cost reduction and mass-scale out

19. v
How does AWS Support .NET & Docker?
• Option 1: Roll your own
• Run Docker on EC2
• Something you may have already tried to do on your local development PC
• Option 2: Use Rapid Deployment Services
• Use the AWS Elastic Beanstalk Service which natively supports both Docker &
Windows IIS
• Great for developers wishing to get started quickly with low interest in the
underlying infrastructure
• Option 3: Use Docker as a Service
• Use the AWS EC2 Container Service (ECS) with full native Docker support
• Great for engineers who want full access to the underlying core infrastructur

20. Live Demo…
