C838- Exam 10 Questions with 100% Correct
Answers.
Broad Network access
means that there should never be network bandwidth bottlenecks. This is generally accomplished
with the use of such technologies as advanced routing techniques, load balancers, multisite
hosting, and other technologies.
on demand services
refer to the model tha tallows customers to scale their compute and/or storage needs with little or
no intervention from prior communication with the provider.
resource pooling
is the characteristic that allows the cloud provider to meet various demands from customers
while remaining financially viable. The cloud provider can make capital investments that greatly
exceed what any single customer could provide on their won and can apportion these resources,
as needed, so that the resources are not underutilized or overtaxed.
measured or metered service
means that the customer is charged for only what they use and nothing more. like how a water or
power company might charge you each month for the eservices used.
ISO/IEC standard
provides an overview and vocabulary for cloud computing(17788) includes these traits, and it
also adds the characteristic of multitenancy.
functional requirements
those performacne aspects of a device, process, or employee that are necessary for the business
task to be accomplished.
non functional requirments
,those aspects of a device, process, or employee that are not necessary for accomplishing a
business task but are desired or expected.
Methods for gathering business requirements
-Interviewing functional managers
-interviewing users
-surveying customers
-interviewing senior management
-collecting network traffic
-inventorying assets
-Collecting financial records
-collecting insurance records
-Marketing data collecting
-Collecting regulatory mandates.
Business Impact analysis (BIA)
is an assessment of the priorities given to each asset and process within the organization. Proper
analysis should consider the effect(impact) any harm or loss of each asset might mean to the
organization overall. During this special care should be paid to identify critical paths and single
points of failure and cost of compliance.
Elasticity
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. Proper cloud
implementations should not request constant or even frequent interaction between the cloud
provider and cloud customer.
Scalability
,the organizations computing needs wont' remain static: there will be new users, customers, and
data as the organization continually matures. new computing resources can be assigned and
allocated without any significant additional capital investment on the pat of the cloud provider,
and at an incremental cost to the cloud customer.
Software as a service
Applications: CRM, Hosted HR, email. Google Docs, Microsoft office 365, Quickbooks Online.
is designed to provide a complete packaged solution. It includes everything listed in the previous
two models, with the addition of software programs. The cloud vendor becomes responsible for
administering, patching, and updating his software as well.
Plateform as a service
Operating systems: Windows, Linux, Unix. contains everything included in IaaS, with the
addition of Os. the cloud vendor usually offers a selection of OSs, so that the customer can use
any or all of the available choices. The vendor will be responsible for patching, administering,
and updating the OS as necessary, and the customer can install any software they deem useful.
This is useful for Software development operations(DevOps), as the customer can test their
software in an isolated environment.
Infrastructure as a service
Hardware, Blades, connectivity, Utilities.
-allows the customer to install all software, including operating systems on hardware housed and
connoted by the cloud vendor. in this model, the cloud provided has a datacenter with racks and
machines and cables and utilites, and administers all these things. Can also be considered a
"Warm" Site.
Pubic cloud
is what we typically think of when discussing clouds providers. These resources (Hardware,
software, facilities, and staff) are owned and operated by a vendor and sold, leased, or rented to
anyone.
Private clouds
, Are owned and operated by independent organizations, for the exclusive use of their customers
and users. Can be thought of as the traditional legacy IT environment, with connections made via
the web and with remote access capabilities. If you organization hosts a web server, and allows
access via remotes services, that can be considered this.
Community cloud
Features infrastructure and processing owned and operated by an affinity group. Disparate pieces
might be owned or controlled y individuals or distinct organizations, but they come together in
some fashion to perform joint tasks and functions. Gaming communities would be used for this.
Hybrid cloud
Contains elements for the other models. Example migh tbe SharePoint site.
Cloud Service provider(CSP)
The vendor offering Cloud services. Will own the datacenter, employ the staff, own and manage
the resources (Hardware and software), monitor service provision and security, and provide
administrating assistance for the customer and the customers data and processing needs.
Examples: AWS, rackspace, Azure.
Cloud Customer
The organization purchasing, leasing, or renting cloud services.
Cloud Access Security Broker(CASB)
A third party entity offering independent identity and access management(IAM) services to
CSP's and cloud customers, often as intermediary. This can take the form of variety of services,
including single sign on, certificate management, and cryptography key escrow.
Regulators
The entities that ensure organizations are compliance with regulator framework for which they're
responsible. These can be Government agencies, certification bodies, or parties to a contract.
