A company has an on-demand self-service portal.
What is the most likely sequence of events in the service catalog when an IaaS service is provisioned?
Answer: 
Explanation:
On-demand self-service enables a consumer to request an IT service through a portal and for that service to be provisioned in a totally automated fashion. This is accomplished through a web-based catalog that lists available services and options. The service catalog is integrated with an orchestration mechanism, which uses predefined templates to provision services. In this example for a web server, the orchestration mechanism communicates with the hypervisor layer and triggers the creation of a service. CPU, RAM, and disk are allocated to the service, along with the proper network connection. The orchestration mechanism can also trigger the creation of other service options, like creating a backup schedule for a service, or provisioning metering and monitoring. The catalog and orchestration mechanism can also track the time that a service is made available and then what to do at lease expiration. Once the service is created, the consumer is alerted and can start consumption.
