What are some computing services •Compute power - e.g. Servers or web applications
offered by a Cloud Provider? •Storage - e.g. Files and Databases
•Networking - e.g. secure connections between the
cloud provider and on-premises.
•Analytics - e.g. visual telemetry and performance

What is Serverless Computing? Serverless computing lets you run application
code(e.g. functions) without creating, configuring,
or maintaining a server. When compared to VMs
and Containers, it is the lightest and fastest
deployment method.

Horizontal scaling: aka "scaling out", is the process
of adding more servers that function together as
one unit. For example, you have more than one

Define: Scalability as it relates to You can increase or decrease the resources and
cloud computing services used based upon the needs of your
organization.

computing in demand, a cloud computing system can
compensate by automatically adding or removing
resources. (e.g. a web-site during Black Friday Sale)
Define: redundancy as it relates to If one component fails, another is available to take
cloud computing its place and its workload.

adequate definition and an example. Users also pay less for power consumption,
cooling and network connectivity than they would
with on-premises infrastructure.
, Compare / Contrast CapEx(Capital •Capital Expenditure: the spending of money on
Expenditure) vs. OpEx(Operational physical infrastructure up front, and then deducting
Expenditure) that expense from your tax bill over time. CapEx is
an upfront cost, which has a value that reduces
over time.
•Operational Expenditure: 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.
What is the primary benefit of Fixed Costs and a predictable expense for your
CapEx? budget! Companies on a tight budget will lean
here.
What is the primary benefit of OpEx? Grows if demand is increased and shrinks
accordingly. For new companies / startups this will
make lots of sense.
What is Cloud agility? Cloud agility is the ability to rapidly change an IT
infrastructure to adapt to the evolving needs of the
business. For e.g. if your service peaks one month,
you can scale to demand and pay a larger bill for
the month. If the following month the demand
drops, you can reduce the used resources and be
charged less. This agility lets you manage your
costs dynamically, optimizing spending as
requirements change.
Describe the Public Cloud Microsoft Azure is a public cloud provider. There is
no local hardware to manage or keep up-to-date -
everything runs on your cloud provider's hardware.
In some cases, you can save additional costs by
sharing computing resources with other cloud
users.
