- 2. Cloud computing is where the organization outsources data processing to computers owned by the vendor. Primarily the vendor hosts the equipment while the audited entities still has control over the application and the data. Outsourcing may also include utilizing the vendor’s computers to store, backup, and provide online access to the organization data. When an organization chooses to utilize cloud computing, they need to be aware of risks that they may face with the service provider.
- 3. Generally speaking, cloud computing can be thought of as anything that involves delivering hosted services over the Internet. According to NIST Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. (Special Publication 800-145)
- 5. On-demand self-service A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider
- 6. Broad network access Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations).
- 7. Resource pooling The provider’s computing resources are pooled to serve multiple consumers Resources can be dynamically assigned and reassigned according to customer demand Customer generally may not care where the resources are physically located but should be aware of risks if they are located offshore
- 8. Rapid elasticity Capabilities can be expanded or released automatically (i.e., more CPU power, or ability to handle additional users) To the customer this appears seamless, limitless, and responsive to their changing requirements
- 9. Measured service Customers are charged for the services they use and the amounts There is a metering concept where customer resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service
- 10. Cloud computing provides shared services as opposed to local servers or storage resources Enables access to information from most web-enabled hardware Allows for cost savings – reduced facility, hardware/software investments, support
- 12. Software as a services end users Platform as a services Application developer Infrastructure as a service Network architects
- 13. Software-as-a-Service Also referred to as “software on demand,” this service model involves outsourcing the infrastructure, platform, and software/applications. Typically, these services are available to the customer for a fee, pay-as-you-go, or a no charge model. The customer accesses the applications over the internet.
- 14. A service model that involves outsourcing the basic infrastructure and platform (Windows, Unix) PaaS facilitates deploying applications without the cost and complexity of buying and managing the underlying hardware and software where the applications are hosted. The customer uses their own applications Platform-as-a-Service (PaaS)
- 16. Infrastructure-as-a-Service A service model that involves outsourcing the basic infrastructure used to support operations--including storage, hardware, servers, and networking components. The service provider owns the infrastructure equipment and is responsible for housing, running, and maintaining it.The customer typically pays on a per-use basis.
