Scalability	Limited by owned resources	Virtually unlimited
Upfront Cost	High (hardware, licenses)	Low (pay-as-you-go)
Ongoing Cost	Lower for steady workloads	Can be high for large scale
Security/Compliance	Customizable, strict	Certified, but shared model
Maintenance	User responsibility	Provider responsibility
Integration	Custom, may require effort	Native to provider ecosystem
Automation	Possible, but DIY	Built-in tools (IaC, CI/CD)
