In a single-cloud deployment, why is FinOps easy?
There is no cloud to compare expenses to, so there is no need to formalize a FinOps program.
Centralized cloud billing simplifies accounting, and the cloud provider often provides FinOps tools that can handle your needs.
Rates can be negotiated for FinOps management more easily when everything is under an umbrella contract.
You can ignore most billing and financial issues.
