A. virtual machines
B. physical network
C. applications
D. hypervisors
E. virtual network
Answer
A. virtual machines
B. physical network
Explanation
The two aspects of the IaaS (Infrastructure as a Service) cloud service model that are managed by the service provider are:
A) Virtual machines
B) Hypervisors
In the IaaS model, the service provider manages the underlying cloud infrastructure including servers, storage, networking, hypervisors, and virtual machines. The consumer has control over the deployed applications, operating systems, middleware etc.
The key aspects managed by an IaaS provider are:
A) Virtual machines – The IaaS provider creates, starts, stops and deletes virtual machine instances as requested by the consumer. The VMs run on top of the hypervisor layer managed by the provider.
B) Hypervisors – The hypervisor software that creates and runs the virtual machines is installed, managed and maintained by the IaaS provider. Popular hypervisor technologies include VMware ESXi, Microsoft Hyper-V, Citrix XenServer etc.
In contrast, other aspects like applications, operating systems, middleware, runtimes, data, networks are managed by the consumer in an IaaS model. The provider manages the lower-level infrastructure while the consumer has control and management over the software stack deployed on top.
In summary, virtual machines and hypervisors are key aspects managed by the IaaS service provider, making options A and D the correct answers. The physical network, applications and virtual networks are managed by the consumer, not the provider.
