Explanation
For an e-commerce application hosted on IaaS, availability of the provider's services is the paramount concern. E-commerce generates revenue directly proportional to uptime - any outage by the cloud provider immediately translates to lost sales, damaged customer trust, and potential SLA violations. Under IaaS, the customer controls the application and OS layers, but the underlying infrastructure availability is entirely dependent on the provider. Internal audit requirements (A) and increased security costs (B) are secondary operational concerns. Application ownership (C) is not a significant concern in IaaS because the customer retains ownership and control of the application - that is a distinguishing feature of IaaS versus PaaS or SaaS.
