Cloud Foundations Chapters 1 to 3
As the roles of IT change with the implementation of cloud-based services, what are 6
expected roles that will be needed to manage organizational use of cloud services? - correct
answer-Capacity planners, Network operation center staff, Vendor management staff,
Support desk, Cloud architects, and Cloud service managers.
Can PaaS use existing traditional technologies? - correct answer-Platform as a Service
cloud options are coupled to a particular vendor's technologies, languages, and other
features. This is similar to the way that many application development environments are
linked to a standard set of tools that their developers will use to create deployable software
in traditional enterprise networks.
Can SaaS services by customized? - correct answer-SaaS alternatives are prebuilt and
cannot be changed beyond personalization and configuration settings by the consumer.
Describe a private cloud. - correct answer-Provisioned for use by a single user or group of
users within an organization, the private cloud is owned, managed, and operated by the
organization. Private clouds reside on a private network owned or managed by the
organization itself.
Describe a Storage Area Network, or SAN. - correct answer-Dedicated network that provides
access to consolidated, block-level data storage. It is used to make storage devices, such as
disk arrays and tape libraries
Describe cloud bursting. - correct answer-Cloud bursting is a hybrid cloud implementation
where local private cloud resources are used in support of an application until a spike in
demand exceeds local resource limits, at which point the app "bursts" out of the private
cloud into designated public cloud resources to manage the overrun.
Describe community clouds. - correct answer-Provisioned for use by a group of related
organizations with shared concerns, such as a group of governmental or educational
institutions that choose to share a common cloud of services not available to the general
public.
Describe distributed virtualization. - correct answer-Extending the virtualization to include
distributed resources using technologies that can transfer operations between automated
systems.
Describe hybrid clouds. - correct answer-Provisioned using components of private,
community, or public clouds, the hybrid cloud provides access to two or more infrastructures
bridged by standardized technologies or proprietary cloud services.
Describe Network Attached Storage, or NAS. - correct answer-File-level data storage that is
connected to a network of heterogeneous computer systems. Manufactured as a computer
appliance and used for specialized purposes.
, Describe public clouds. - correct answer-Provisioned for use the general public, public cloud
services represent the most thoroughly virtualized cloud infrastructural design, removing
data center information resources partially or completely. Public clouds reside on hosting
data center resources and are accessed via the public Internet.
Describe server virtualization. - correct answer-An organization has one or more data
centers that get all of their server resources from one virtualized server sitting on a separate
hardware machine. That one machine, running software such as Hyper-V or Vmware,
contains the virtualized server that can be moved to a different machine if needed due to
tech refreshes, disasters, etc.
Give 2 examples of Big Data. - correct answer-Long-term weather forecasting, or analysis of
economic trends across the entire stock market.
Give 3 examples of database services that are based in the cloud. - correct
answer-Database as a Service (DBaaS), Data Mining as a Service (DMaaS), and Data
Warehousing as a Service (DWaaS).
Give 3 examples of providers that offer PaaS services. - correct answer-Google app engine,
WindowsAzure, and Rackspace.
Give 4 examples of providers that offer IaaS services. - correct answer-WindowsAzure,
Amazon Web Services, Google Compute Engine, and DropBox.
Give 5 examples of providers that offer SaaS services. - correct answer-Google apps,
Office365, ZOHO, SalesForce, and Aviary.
Give an example of how a PaaS provider can use its traditional technologies. - correct
answer-Microsoft's Visual Studio templates allow choosing MicrosoftAzure as one of the
available template options.
Give an example of how an organization could create customized cloud service
implementation to meet their specific needs. - correct answer-Organizations may choose to
host private, community, or parts of hybrid clouds either on site or outsourced to a hosting
provider. This differs from a public cloud in that access remains limited to the appropriate
category (private, community, or hybrid) even though the equipment is located beyond the
organization's data center.
Give an example of Vendor Lock-in. - correct answer-A Keurig coffeemaker, which can make
coffee using only its proprietary single-serving packs.
Give examples of XaaS, or Everything as a Service options that are available in cloud
computing. - correct answer-XaaS includes SaaS, PaaS and IaaS as well as many other
cloud service models such as Business Processes as a Service (BPaaS), Communication as
a Service (CaaS), Monitoring as a Service (MaaS), and many others.
