Containers vs VM
Container fundamentals
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 ?
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
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
What is supported for WCF ?
• Http /Https endpoints
• IIS Hosting
• Self Hosting
• Anonymous access endpoints
