Implementation challenges for controls on CSP side

Every customer might have different requirements for controls and if they move to a cloud environment, they need to also make sure that the CSP has implemented those controls.

AWS is a PCI DSS level 1 service provider:

Similarly, there might be other customers who might need ISO 27001 or HIPAA compliant provider and so CSP needs to make sure to have controls in place and to be in compliance with those certifications.
