What are the Cloud Components

Analytics and intelligence


What are the benefits of Cloud.Describe each Benefit

Cost - eliminates capital costs

Speed. Can provision in minutes

Global Scale. Ability to Scale elastically. More or less computing power,storage, bandwidth right when it is needed;
Performance: Run on world wide network of data centers which are regularly upgraded to fat and efficient hardware

Security: broad set of security controls to protect

Productivity: no more racking and stacking, hardware setup software patching
Reliability: Makes backups and disaster recovery easier and less expensive. Data is mirror to multiple sites


What component is allows creation of users and groups in the cloud

Azure AD


What are the 3 types of Cloud platforms



Describe IAAS

Renting of Servers and virtual machines, Storage and Operating systems.


Describe PAAS

Provides on demand taylormade environments for developing, testing, delivering and managing software applications.


What group is most like to use PAAS

Developers are most likely to use PAAS. it eases the burden of having to configuring operating systems,storage etc so they cna get directly to developing


Describe SAAS

Delivering software over the internet on a subscription basis.


Types of Cloud

Public., Private, Hybrid


Describe Hybrid Cloud

connects one or more public or private clouds. Generally used for transition or to meet security requirements


Describe Hybrid Cloud

connects one or more public or private clouds. Generally used for transition or to meet security requirements


Public Cloud Pros and Cons

Highly scalable
Pay as you go
not responsiable for maintence or updates fo hardware
minimal technical knowledge


May be issues meeting specifica security requirements
Government or industry/legal standards may not be able to be met
You do not own the hardware or services and give up management control


Hybrid Cloud Pros and Cons

You can keep any systems running and accessible that use out of date hardware or operating systems
You have flexibility with what is run locally versus the cloud
You can take advantage of economies of scale

It can be more expensive then selecting one deployment and involves some Capex

It is more complicated to setup and manage


Private Cloud Pros and Cons

Ensure the configuration and support any scenario or legacy application.
You have control and responsibility over security.
Private clouds can meet strict security, compliance or legal requirements
Economies at scale and integration with Azure Security center

Capex, you must purchased all hardware and maintain it
Owning equipment limits agility, you must spend money to expand install , setup new
Require skilled IT personnel that is hard to come by


IAAS know for the exam

Infrastructure as a service (laaS)
laaS is the most flexible category of cloud services.

It gives you complete control over the hardware that runs your
application (IT infrastructure servers and virtual machines (VMS),
storage, networks, and operating systems). Instead of buying
hardware, with laaS, you rent it.
It's an instant computing infrastructure, provisioned and managed
over the internet.
laaS is commonly used in the following scenarios
'Migrating workloads
'Test and development
OStorage, backup, and recovery


PAAS know or the exam

Platform as a service (PaaS)
PaaS provides an environment for building, testing, and deploying
software applications.
The goal of PaaS is to help you create an application quickly without
managing the underlying infrastructure. For example, when deploying
a web application using PaaS, you don't have to install an operating
system, web server, or even system updates.
PaaS is commonly used in the following scenarios
'Development framework
'Analytics or business intelligence


SAAS know for the exam

Software as a service (SaaS)

SaaS is software that is centrally hosted and managed for the end customer.
It is usually based on an architecture where one version of the application is used for all customers, and licensed through a monthly or annual subscription.
Office 365, Skype, and Dynamics CRM Online are perfect examples of SaaS software.



Capital expenditure (CapEx) versus operational
expenditure (OpEx)
Two approaches to investment are referred to as:
Capital Expenditure (CapEx)
CapEx is the spending of money on physical infrastructure up front,
and then deducting that expense from your tax bill qver time.
CapEx is an upfront cost, which has a value that reduces over time.
Operational Expenditure (OpEx)
OpEx is spending money on services or products now and being
billed for them now. You can deduct this expense from your tax bill
in the same year. There's no upfront cost. You pay for a service or
product as you use it.
