MIS 301 EXAM #3 SECTION 1 QUESTIONS AND
VERIFIED ACCURATE ANSWERS
What is cloud computing? What are the essential characteristics of cloud computing? -
Answers - Cloud computing is a model for enabling on-demand network access
(INTERNET) to a shared pool of configurable computing resources (e.g. servers,
storage, applications) that can be rapidly provisioned with minimal service provider
interaction.
When talking about cloud computing, people are speaking of replacing software and
hardware with services offered over the internet.
The essential Characteristic of Cloud Computing include: - Answers - 1. On-demand
self-service: A consumer can be provided with computing capabilities when needed,
usually without requiring human interaction with the service provider.
2. Broad Network Access: Multiple users are able to interact over a large scale of
devices
3. Resources Pooling: Multi-Tenancy Model- the resources are dynamically assigned
and reassigned according to consumer demand. With Location Independence - the
client has little or no control or knowledge over the exact location of the hardware
supporting the provided resources.
4. Measured Service: Resource usage can be monitored, measured (according to
various metrics), controlled/optimized, and reported, provided transparency for both the
provider and consumer.
5. Rapid Elasticity (Scalability)
- Resources can be rapidly and elastically provisioned to quickly scale out when
needed.
2. What is IaaS? - Answers - Infrastructure as a Service or IaaS is an alternative to
physical hardware; resources are allocated/made available online.
What are the resources an IaaS cloud vendor will provide/manage and what are the
resources the cloud user will have control over? - Answers - The capability provided the
customer is to rent processing, storage, networks, and other fundamental computing
resources from the provider where the consumer is able to deploy and run arbitrary
software.
Example: Amazon offering Cloud Service to Netflix.
What does the Customer control with Iaas? - Answers - The customer has control over
operating systems, deployed applications, and possibly limited control of select
networking components.
