Download as PPTX, PDF0 likes124 views
The document provides a detailed overview of scaling multi-container applications using Azure Container Service (ACS) and Docker Swarm. It outlines the journey of containerized applications from local development to deployment, including packaging, publishing to Docker Hub, and managing services in a swarm cluster. Additionally, it includes demonstrations and references to relevant resources for further learning.

Editor's Notes
- #5: Clarify the point that the session is not about using docker Assumption is that a basic knowledge of docker is available with the viewers
- #11: Show Dockerfile from VS code if possible for both API & MVC apps
- #12: Highlight image sizes using coreaspnet image and the custom images
- #13: Walkthrough about how to start with .NET core.
- #14: Differentiate between interactive mode and detached mode while starting docker containers Real life apps with more than 2 containers and dependencies among them
- #17: Highlight the builds order based on dependencies specified Talk about detached mode
- #18: Walkthrough about how to start with .NET core.
- #19: Tagging does not create new image but reuses the existing one Image layers reused by docker hub to reduce network transfer
- #20: Manages and organises docker containers across multiple hosts via the same API used by single docker host Highlight 2375 port number used in ACS service
- #23: Mention 10-15 mins time required for provisioning the machines / resources in Azure
- #27: Mention about SSH tunnelling Highlight difference between provisioning and actual agent nodes Highlight difference between management connection for deployment & agent connection for accessing the delayed sites Highlight zero lines of code changes & infrastructure as code aspects
