Explanation:
Platform as a Service would allow software developers to quickly and easily deploy their applications among different hosting providers for testing and validation in order to determine the best option. Although IaaS would also be appropriate for hosting applications, it would require too much configuration of application servers and libraries in order to test code. Conversely, PaaS would provide a ready-to-use environment from the onset. DaaS would not be appropriate in any way for software developers to use to deploy applications. IaaS would not be appropriate in this scenario because it would require the developers to also deploy and maintain the operating system images or to contract with another firm to do so. SaaS, being a fully functional software platform, would not be appropriate for deploying applications into.

Measured service is where cloud services are delivered and billed in a metered way, where the cloud customer only pays for those that they actually use, and for the duration of time that they use them.

FIPS 140-2 is a United States certification standard for cryptographic modules, and it provides guidance and requirements for their use based on the requirements of the data classification.
However, these are not actual regulatory requirements. The Health Insurance Portability and Accountability Act (HIPAA), Sarbanes-Oxley Act (SOX), and the Payment Card Industry Data Security Standard (PCI DSS) are all major regulatory frameworks either by law or specific to an industry.
