• Running WCF Services in windows containers
• Demos

4. Containers vs VM

5. Containers vs VM

6. Container fundamentals

7. Windows containers
• What are Containers ?
• Windows Server Containers
• Provides isolation through process & namespace technology
• Hyper-V Containers
• Provides isolation by running each container in highly optimized VM
• When to use what ?

8. Microservices
• Microservices is an approach to application development where every
part of the application is deployed as a fully self-contained
component, called a microservice that can be individually scaled and
updated.
• Agility - can scale out dynamically depending on usage, with resource
isolation every service is restrained from accessing other service’s
resources
• Solves Management, Deployment, Orchestration and patching needs
without affecting High availability

9. WCF services in containers ?
• Windows containers are now available to use
• Service endpoints are easy to configure
• Reduce or eliminate maintenance of Virtual machines
• Better support for service oriented architecture

10. What is supported for WCF ?
• Http /Https endpoints
• IIS Hosting
• Self Hosting
• Anonymous access endpoints

11. WCF Image Dockerfile
FROM microsoft/iis
SHELL [“powershell”, “-command”, “$ErrorActionPreference = ‘Stop’;
$ProgressPreference=‘SilentlyContinue’;”]
RUN Add-WindowsFeature NET-WCF-HTTP-Activation45;
Add-WindowsFeature NET-WCF-TCP-Activation45;
Add-WindowsFeature Web-WebSockets
