Disadvantages of Windows Containers
• Bigger in size
• longer push/pull times
• Require more storage (affects Kubernetes & PaaS)
• Higher resource consumption
• Windows Containers & Hosts need more CPU & memory
• Direct impact on infrastructure budged
• Host & container OS must have same version (strict policy)
• https://kubernetes.io/docs/concepts/windows/intro/#windows-os-version-support
• Meaning you may end up with way more infrastructure
