Kubernetes for .NET Developers
The document discusses different cloud computing technologies including IaaS, CaaS, PaaS, and FaaS. IaaS provides virtual machines and infrastructure hosting. CaaS focuses on container platforms like Kubernetes. PaaS offers application platforms like Azure App Service. FaaS enables serverless computing through functions and logic apps that scale to zero. The document then discusses advantages of Kubernetes and containers for portability, density, and rapid scaling of applications.
