MGT 2210 Test 3 Questions With
Complete Answers
Cloud Computing - ANSWER A model for enabling ubiquitous, convenient, on-
demand network access to a shared pool of configurable computing resources
that can be rapidly provisioned and released with minimal management effort or
service provider interaction (Renting rather than buying resources)
Resource Pooling - ANSWER Provider's are pooled to serve multiple consumers
Resource pooling - Multi-tenancy - ANSWER Multiple users sharing one resource
or infrastructure-different physical and virtual resources dynamically assigned
and reassigned according to consumer demand.
Resource Pooling- Virtualization - ANSWER Allow resources on one computer to
be split into multiple "virtual" minicomputers (many boxes in a box) inside which
applications can be run separately
Characteristics of Cloud Computing - ANSWER On-demand self-service, rapid
elasticity(scalability), measured/metered service, broad network access
On-demand self service - ANSWER 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.
Rapid Elasticity (scalability) - ANSWER Rapidly and elastically provisioned to
quickly scale up when needed
Measured/Metered Service - ANSWER Resource usage can be monitored,
measured, controlled/optimized, and reported providing transparency for both
the provider and the consumer of the utilized service
Broad Network Access - ANSWER Wherever there is a network, you could have
access
Softward as a Service (SaaS) - ANSWER The capability proved to the consumer
is *to use*
Available through a "thin" client interface--FOR THE USER
The consumer does not manage the cloud infrastructure
Platform as a Service (PaaS) - ANSWER The capability provided to the consumer
is to deploy onto the
, cloud infrastructure consumer-created or acquired applications created using
programming languages, libraries, services, and tools supported by the
provider.
The consumer does not manage or control the underlying cloud infrastructure
including
network, servers, operating systems, or storage, but has control over the
deployed
applications and possibly configuration settings for the application-hosting
environment.
Infrastructure as a Service (IaaS) - ANSWER The capability provided to the
consumer is to rent processing, storage, networks, and other fundamental
computing resources from the provider
Consumer is able to deploy and run software of their choice (can be OS or an
application)
Consumer DOES NOT manage infrastructure but can control operating systems,
storage, applications, and possible and limited control of networking
components
Brokers - ANSWER Provide support and tools for deploying/running apps in the
cloud
Do not own the infrastructure/platform but intermediate access of the customer
to the infrastructure/platform
Consumer does not manage infrastructure but can control which provider is
used, resource consumption balance, etc.
Public Clouds - ANSWER The cloud infrastructure is made available to the
general public or a large industry group and is owned by an organization selling
cloud services.
Private Clouds - ANSWER The cloud infrastructure is operated solely for an
organization. It may be managed by the organization or a third party and may
exist on premise or off premise.
Benefits of cloud computing - ANSWER Subscription pay-per-use models for
firms
Increased efficiency-(no idle assets, less IT maintenance, IT resources can
focus on core competencies.
Rapid access/rapid deployment
Scalability
Greener Computing-less energy/materials required
Concerns of Cloud Computing - ANSWER Security-Data confidentiality, service
provider's than firm itself
Availability-Internet connection, risk of crash
