QUESTIONS AND ANSWERS
Elasticity. ANSWER -This is the flexibility of allocating resources as needed for immediate
usage, instead of purchasing resources according to other variables
Simplicity. ANSWER -Usage and administration of cloud services ought to be transparent
to cloud customers and users; from their perspective, a digital data service is paid for and
can be used, with very little additional input other than what is necessary to perform their
duties.
Scalability. ANSWER -The organization's computing needs won't remain static: there will
be new (and hopefully more) users, customers, and data as the organization continually
matures.

own the datacenter, employ the staff, own and manage the resources (hardware and
software), monitor service provision and security, and provide administrative assistance for
the customer and the customer's data and processing needs.
Cloud Access Security Broker (CASB). ANSWER -A third-party entity offering
independent identity and access management (IAM) services to CSPs and cloud customers,
often as an intermediary. This can take the form of a variety of services, including single
sign-on, certificate management, and cryptographic key escrow.

Cloud Backup:. ANSWER -Backing up data to a remote, cloud-based server. As a form of
cloud storage, cloud backup data is stored in an accessible form from multiple distributed
resources that comprise a cloud.
Cloud Computing:. ANSWER -A type of computing, compared to grid computing, that
relies on ensuring computing resources rather than having local server or personal devices
to handle applications. The goal of cloud computing is to apply traditional supercomputing
or high-performance computing power, normally used by military and research facilities, to
perform tens of trillions of computations per second and consumer-oriented applications
such as financial portfolios, or even to deliver personalized information or power immersive
computer games.
Cloud Computing Reseller:. ANSWER -A company that purchases hosting services from a
cloud server hosting or computing provider and then resells them to its own customers.
Cloud Migration:. ANSWER -The process of transitioning all or part of a company's data,
applications, and services from onsite premises to the cloud, where the information can be
provided over the Internet on an on-demand basis.

between one cloud provider and another, or between legacy and cloud environments.
Cloud Provider:. ANSWER -A service provider that offers customer storage or software
solutions available via a public network, usually the Internet. The cloud provider dictates
both the technology and operational procedures involved.
,Cloud Services Broker (CSB):. ANSWER -Typically a third-party entity or company that

concerns, missions, and/or security requirements.
Enterprise Application:. ANSWER -The term used to describe applications or software that
a business would use to assist the organization in solving enterprise problems.
Eucalyptus:. ANSWER -An open source cloud computing and Infrastructure as a Service
(IaaS) platform for enabling private clouds.
FIPS 140-2. ANSWER -A NIST document that lists accredited and outmoded
cryptosystems.
Hybrid Cloud:. ANSWER -A cloud solution that mixes elements of public, private, and
community cloud models.
Infrastructure as a Service (IaaS). ANSWER -Offers only hardware and administration,
leaving the customer responsible for the OS and other software.
Managed Service Provider:. ANSWER -An IT service where the customer dictates both the
technology and operational procedures, and an external party executes administration and
operational support according to a contract.
, Multi-Tenant:. ANSWER -Multiple customers using the same public cloud (and often the
same hosts, in a virtualized cloud environment).
NIST 800-53:. ANSWER -A guidance document with the primary goal of ensuring that
appropriate security requirements and controls are applied to all U.S. federal government
information in information management systems.
Platform as a Service (PaaS):. ANSWER -A way for customers to rent hardware, operating
systems, storage, and network capacity over the Internet from a cloud service provider.
Private Cloud:. ANSWER -The phrase used to describe a cloud computing platform that is
implemented within the organization. A private cloud is designed to offer the same features
and benefits of public cloud systems but removes a number of objections to the cloud
computing model, including control over enterprise or customer data, worries about
security, and issues connected to regulatory compliance or contractual agreements.
Software as a Service (SaaS):. ANSWER -It is a software delivery method that provides
access to software and its functionality remotely as a web-based service. Software as a
Service allows organizations to access business functionality at a cost typically less than
paying for licensed application because SaaS pricing is based on a monthly fee.
