   • AUse the same configuration management and deployment scripts for both staging and production, but allow for differences in scale.
   • BSkip staging and deploy directly to production with a canary release.
   • CUse a smaller instance type for staging and manually adjust configuration files for each environment.
   • DDeploy to production first and then copy the production configuration to staging.
