AWS Cloud computing

Question 1

What is cloud computing?

Answer 1

Cloud computing is the on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform via the internet with pay-as-you-go pricing.

Question 2

Six advantages

Answer 2

1. Trade capital expense for variable expense
2. Benefit from massive economies of scale
3. Stop guessing capacity
4. Increase speed and agility
5. Stop spending money on running and maintaining data centers
6. Go global in minutes

Question 3

Infrastructure as a Service (IaaS)

Answer 3

contains the basic building blocks for cloud IT and typically provide access to networking features, computers (virtual or on dedicated hardware), and data storage space.

Question 4

Platform as a Service (PaaS):

Answer 4

remove the need for organizations to manage the underlying infrastructure (usually hardware and operating systems) and allow you to focus on the deployment and management of your applications.

Question 5

Software as a Service (SaaS)

Answer 5

with a completed product that is run and managed by the service provider.

Question 6

Cloud

Answer 6

fully deployed in the cloud and all parts of the application run in the cloud.

Question 7

Hybrid

Answer 7

A hybrid deployment is a way to connect infrastructure and applications between cloud-based resources and existing resources that are not located in the cloud.

Question 8

On-premises

Answer 8

The deployment of resources on-premises, using virtualization and resource management tools, is sometimes called the “private cloud.”

Question 9

Global Infrastucture

Answer 9

to help our customers achieve lower latency and higher throughput, and to ensure that their data resides only in the AWS Region they specify.

Question 10

AWS Region

Answer 10

AWS Region is a physical location in the world where we have multiple Availability Zones.

Question 11

AWS Availability Zones

Answer 11

Availability Zones consist of one or more discrete data centers, each with redundant power, networking, and connectivity, housed in separate facilities.

Question 12

AWS Region or AWS Availability zones… isolated?

Answer 12

Each Amazon Region is designed to be completely isolated from the other Amazon Regions. This achieves the greatest possible fault tolerance and stability. Each Availability Zone is isolated, but the Availability Zones in a Region are connected through low-latency links.

Question 13

Answer 13

1. Keep Your Data Safe
2. Meet Compliance Requirements
3. Save Money
4. Scale Quickly

Question 14

AWS Compliance

Answer 14

enables you to understand the robust controls in place at AWS to maintain security and data protection in the cloud

Question 15

basic AWS Cloud architectural principles

Answer 15

1. Stop guessing your capacity needs
2. Test systems at production scale
3. Automate to make architectural experimentation easier
4. Allow for evolutionary architectures
5. Drive architectures using data
6. Improve through game days
