1. What are some computing services offered by a Cloud Provider?
f f f f f f f f f
…Answer:> •*Compute power* - e.g. Servers or web applications

• *Storage* - e.g. Files and Databases
f f f f f
• *Networking* - e.g.secure connections between the cloud provider and on-premis- es.
f f f f f f f f f f f
• *Analytics* - e.g. visual telemetry and performance data

2. Jim the systems admin at a fictitious company is an absolute control freak! From the
f f f f f f f f f f f f f f
f list below, choose the most appropriate cloud solution for him:
f f f f f f f f f
a). Virtual Machines f
b). Containers
,c). Serverless compute f
…Answer:> a). *Virtual Machines.* Because he will emu- late a physical system, Jim can do
ff f f f f f f f f f f f f f
whatever he likes (e.g.install software, configure updates etc.)
f f f f f f f f f
3. Give the simplest definition of a container.
f f f f f f
…Answer:> A container is similar to a VM but it doesn't need a guest operating system.
f ff f f f f f f f f f f f f f f
4. What is Serverless Computing?
f f f
…Answer:> Serverless computing lets you run application code(e.g. functions) without
f ff f f f f f f f f
f creating, configuring, or maintaining a server. When compared to VMs and Containers, it is
f f f f f f f f f f f f f
the lightest and fastest deployment method.

5. Rob is new to cloud computing and is confused by the terms: "Vertical Scaling" and
f f f f f f f f f f f f f f
"Horizontal" scaling.Give him a brief rundown on the differences between the two!
f f f f f f f f f f f f f
…Answer:> *Vertical scaling*: aka "scaling up", is the process of adding resources to
fff f f f f f f f f f f f
f increase the power of an existing server. Some examples of vertical scaling are: *adding
f f f f f f f f f f f f f
f more CPUs, or adding more memory*.
f f f f f
*Horizontal scaling*: aka "scaling out", is the process of adding more servers that function
f f f f f f f f f f f f f
together as one unit. For example, *you have more than one server processing incoming
f f f f f f f f f f f f f f
f requests*
6. Define: Scalability as it relates to cloud computing
f f f f f f f
…Answer:> You can increase or de- crease the resources and services used based upon the
f ff f f f f f f f f f f f f f
needs of your organization.
f f f f
, 7. Define: Elasticity as it relates to cloud computing
f f f f f f f
…Answer:> As your workload changes due to a spike or drop in demand, a cloud computing
f ff f f f f f f f f f f f f f f
f system can compensate by automatically adding or removing resources. (e.g. a web-site
f f f f f f f f f f f
f during Black Friday Sale)
f f f
8. Define: redundancy as it relates to cloud computing
f f f f f f f
…Answer:> If one component fails, another is available to take its place and its workload.
f ff f f f f f f f f f f f f f
9. Define: fault-tolerance as it relates to cloud computing
f f f f f f f
…Answer:> Customers and end-users are not impacted when a disaster occurs.

10. Misha the cloud computing class nerd wants to engage you in a discussion on Economies
f f f f f f f f f f f f f f
f of Scale. Start the conversation off with an adequate definition
f f f f f f f f f
and an example.f f
…Answer:> Economies of scale is *the ability to do things more efficiently or at a lower-
f fff f f f f f f f f f f f f f f
cost per unit when operating at a larger scale.* In other words, more money is saved, when
f f f f f f f f f f f f f f f f
f production rates are higher. Users also pay less for power consumption, cooling and network
f f f f f f f f f f f f f
f connectivity than they would with on-premises infrastructure.
