This document discusses programming languages popularity, cloud platform usage, building and deploying a .NET Core web application, and deploying Prometheus on Kubernetes. It includes charts showing the popularity of languages like JavaScript, Python and Java in 2018. It also shows how to containerize a .NET Core app, publish it to a container registry, deploy it to Azure Container Instances, and monitor it using Prometheus on Kubernetes.

Editor's Notes
- #5: What are employees looking for worldwide? According to hacker rank that JavaScript is the leader, followed by Java and Python and C# is in 6th place https://research.hackerrank.com/developer-skills/2018/
- #6: What does github and OSS world have to say about that? We can se the same pattern here with javascript also winning the battle and a tie between Java and Python C# is in the 8th place
- #7: % Of Respondants Running Applications 1000 respondants
