◉ Jim the systems admin at a fictitious company is an absolute
control freak! From the list below, choose the most appropriate cloud
solution for him:
a). Virtual Machines
b). Containers
c). Serverless compute Answer: ANSWER: a). *Virtual Machines.*
Because he will emulate a physical system, Jim can do whatever he
likes (e.g. install software, configure updates etc.)
◉ Give the simplest definition of a container. Answer: A container is
similar to a VM but it doesn't need a guest operating system.
◉ What is Serverless Computing? Answer: 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.
◉ Rob is new to cloud computing and is confused by the terms:
"Vertical Scaling" and "Horizontal" scaling. Give him a brief
rundown on the differences between the two! Answer: *Vertical
scaling*: aka "scaling up", is the process of adding resources to
increase the power of an existing server. Some examples of vertical
scaling are: *adding more CPUs, or adding more memory*.
,*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 server processing incoming requests*
◉ Define: Scalability as it relates to cloud computing Answer: You
can increase or decrease the resources and services used based upon
the needs of your organization.
◉ Define: Elasticity as it relates to cloud computing Answer: As your
workload changes due to a spike or drop 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 cloud computing Answer: If one
component fails, another is available to take its place and its
workload.
◉ Define: fault-tolerance as it relates to cloud computing Answer:
Customers and end-users are not impacted when a disaster occurs.
◉ Misha the cloud computing class nerd wants to engage you in a
discussion on Economies of Scale. Start the conversation off with an
adequate definition and an example. Answer: Economies of scale is
*the ability to do things more efficiently or at a lower-cost per unit
when operating at a larger scale.* In other words, more money is
saved, when production rates are higher. Users also pay less for power
consumption, cooling and network connectivity than they would with
on-premises infrastructure.
, ◉ Compare / Contrast CapEx(Capital Expenditure) vs.
OpEx(Operational Expenditure) Answer: •*Capital Expenditure*: the
spending of money on physical infrastructure up front, and then
deducting 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 CapEx? Answer: Fixed Costs and a
predictable expense for your budget! Companies on a tight budget
will lean here.
◉ What is the primary benefit of OpEx? Answer: Grows if demand is
increased and shrinks accordingly. For new companies / startups this
will make lots of sense.
◉ What is Cloud agility? Answer: 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 Answer: 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.
