cloud computing The on-demand delivery of compute power, applications, storage, and other IT
resources through a cloud services platform via the Internet with a pay-as-you-
pricing model.
Describe at least 3 benefits of using a cloud services - rapid access to flexible and low-cost IT resources
platform like AWS. - provision/scale to fit your business needs precisely
- pay for what you use -> pay as you go pricing
model
- reduction in cost as hardware and
management will be maintained by the cloud
service provider allowing more time and money to
focus on development and production.
- efficiency with "guarantees" from the cloud service
provider
List at least (3) problems solved by the cloud? - flexibility
- cost effectiveness
ex: fault-tolerant - scalability
- elasticity
- high-availability & fault-tolerance
- agility
What are the 3 deployment models of the cloud? Public Cloud, Private Cloud, and Hybrid Cloud
What are the different types of cloud computing? Infrastructure as a Service (IaaS)
Platform as a Service ( Paas)
Software as a Service (SaaS)
Define the public cloud model. Cloud resources owned and operated by a 3rd party cloud service provider
delivered over the internet. (typical/general used model)
Name at least 2 public cloud providers. Amazon Web Service (AWS)
Google Cloud Platform(GCP)
MSFT Azure
Name at least 2 private cloud providers. Rackspace
Accenture
Infosys
Capegemini
What is the hybrid cloud model? (Provide an example of a Utilizing on-prem servers and cloud services together.
use case.)
Use Cases/Examples:
- for disaster recovery and high availability
- for archive storage --> AWS Glacier
- cloud bursting --> traffic spilling over to the cloud
during seasonal spike or event
- regulatory requirements
What is a use case for the private cloud model? 1. Cost - having a dedicated cloud server may result in a lower TCO for workloads
that require a steady-state load 24x7.
2. Security Requirements - single organization owned cloud server space which
makes it suitable for sensitive applications which may need some specific business
needs.
3. Complete control.

Infrastructure as a Service (IaaS) - Provides building blocks for cloud-based tech
- Provides networking, computing, data storage
space --> infrastructure
- Highest level of flexibility
- Easy parallel with traditional on-premises IT
Ex:
- AWS EC2, S3, rackspace, digital ocean
Using dozens+ of VMs(virtual machines, or hypervisors/AMIs) to scale services up
and down according to business needs.
Platform as a Service( PaaS) A cloud computing service that removes need for your organization to manage the
underlying infrastructure and allows you to focus on deployment and management
of your applications.
Platforms are built on infrastructure. Platforms are used by devs and engineers to
build and create customized applications.
Ex: AWS Elastic Beanstalk, Heroku, Openshift, Google App Engine
Define Software as a Service(SaaS) aka Cloud application services, uses the internet to to deliver applications, which
are managed by 3rd party vendor, to its users.
Provide an example of a use case and an SaaS
product/application. SaaS is ran and managed by cloud service provider.
ex:
- Gmail, jira, dropbox, AWS Recognition
What are the (3) pricing fundamentals of AWS? 1. Compute- pay for compute time.
2. Storage- pay for data stored on cloud
3. Data transfer out of cloud.
*note: Data transfer into cloud is FREE.
What are (5) characteristics of cloud computing? 1. On-demand Self service - provision without human interactions from cloud
service provider
2. Broad network access- resources are available over network and can be
accessed by diverse client platforms
3. multi-tenancy & resource pooling - multiple customers can share the same
infrastructure with security and privacy.
4. rapid elasticity & scalability - automatically and quickly acquire and dispose
resources when needed
5. measured services - pay for/per use
What are the (6) advantages of cloud computing? 1. Trade CAPEX ( capital expense) for OPEX (operational expense) or variable
expense.
2. Broad network access.
3. Stop guessing about capacity.
4. Increased speed and agility.
5. Stop spending money running & maintaining data centers.
6. Go global within minutes
Define TCO. TCO = total cost of ownership
How does it drive the decision making process Amazon's TCO calculator estimate the cost savings when using AWS and provides
transitioning from on-premises infrastructure to the cloud? a detailed set of reports that can be used in executive presentation.
TCO calculators compares on-prem cost vs AWS cost based on business needs.

What is an AWS region? B.) A region is a geographical area that consists of different availability zones. Each
region consists of 2 (or more) Availability Zones
a) A region is an independent data center, located in
different countries around the globe
b) A region is a geographical area that consists of different
availability zones. Each region consists of 2 (or more)
Availability Zones.
c) A region is a collection of Edge Locations available in
specific countries.
d) A region consists of a number of different subset of AWS
technologies. For example the compute region consists of
EC2, ECS, Lambda etc.
AWS Availability Zone (AZ) AZs consist of one or more discrete data centers, each with redundant power,
networking and connectivity.
the average number of AZ's a region may contain 3
the minimum number of AZ's a region may contain 2
maximum number of AZs a region may contain 6
Edge location ( point of presence) A site that CloudFront uses to cache copies of your content for faster delivery to
users at any location.
***( CDN- content delivery network.)
AWS global service An AWS service that is available for use globally and is not dependent on the
region, availability zone or proximity to edge locations.
These services work independently of geographic location of resources
list 2 AWS global services IAM (Identity Access Management)
Route53 (DNS Service)
WAF (Web Application Firewall)
CloudFront ( CDN)
identify 2 region-specific services EC2 (IaaS)
Elastic Beanstalk ( PaaS)
Lambda (FaaS)
Rekognition (SaaS)
Shared responsibility model Defines the responsibility of the customer and AWS in regards to how the cloud is
managed.
AWS manages the security of the cloud.
The customer is responsible for everything in the cloud.
Benefits of AWS security - Keep your data safe.
- Meet compliance requirements.
- Save money.
- Scale quickly.
