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

§ Strategic enterprise systems
that need to constantly evolve
business capabilities/features
§ Application that requires a
high release velocity - with
high confidence
§ System where individual
features must release without
a full redeployment of the
entire system
§ Application developed by
teams with expertise in
different technology stacks
§ Application with components
that must scale independently
§ ℹ Smaller, less impactful LOB
applications might fare well
with a simple monolithic
architecture hosted in a Cloud
PaaS environment
