C838 V2 - Exam 13 Questions with 100% Correct
Answers.
Elasticity
This is the flexibility of allocating resources as needed for immediate usage, instead of
purchasing resources according to other variables
Simplicity
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
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.
Cloud Service Provider (CSP)
The vendor offering cloud services. They will 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)
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.
Apache Cloud Stack:
An open source cloud computing and IaaS platform developed to help make creating, deploying,
and managing cloud services easier by providing a complete "stack" of features and components
for cloud environments.
Business Requirement:
,An operational driver for decision making and input for risk management.
Cloud App (Cloud Application):
The phrase used to describe a software application accessed via the Internet; may include an
agent or applet installed locally on the user's device.
Cloud Architect:
Subject matter expert for cloud computing infrastructure and deployment.
Cloud Backup:
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:
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:
A company that purchases hosting services from a cloud server hosting or computing provider
and then resells them to its own customers.
Cloud Migration:
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.
Cloud OS:
A phrase frequently used in place of PaaS to denote an association to cloud computing.
,Cloud Portability:
The ability to move applications and associated data between one cloud provider and another, or
between legacy and cloud environments.
Cloud Provider:
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):
Typically a third-party entity or company that looks to extend or enhance value to multiple
customers of cloud-based services through relationships with multiple cloud service providers. It
acts as a liaison between cloud services customers and cloud service providers, selecting the best
provider for each customer and monitoring the services.
Cloud Storage:
The storage of data online in the cloud, wherein a company's data is stored in an accessible form
from multiple distributed and connected resources that comprise a cloud.
Cloud Testing:
Load and performance testing conducted on the applications and services provided by a cloud
provider, particularly the capability to access the services, in order to ensure optimal
performance and scalability under a wide variety of conditions.
Community Cloud:
A model where the cloud infrastructure is designed for use by a specific community. Generally,
this is a community of users or consumers with shared concerns, missions, and/or security
requirements.
Enterprise Application:
The term used to describe applications or software that a business would use to assist the
organization in solving enterprise problems.
, Eucalyptus:
An open source cloud computing and Infrastructure as a Service (IaaS) platform for enabling
private clouds.
FIPS 140-2
A NIST document that lists accredited and outmoded cryptosystems.
Hybrid Cloud:
A cloud solution that mixes elements of public, private, and community cloud models.
Infrastructure as a Service (IaaS)
Offers only hardware and administration, leaving the customer responsible for the OS and other
software.
Managed Service Provider:
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:
Multiple customers using the same public cloud (and often the same hosts, in a virtualized cloud
environment).
NIST 800-53:
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):
A way for customers to rent hardware, operating systems, storage, and network capacity over the
Internet from a cloud service provider.
Private Cloud:
