• Stop spending money running and maintaining data centers
• Go global in minutes

Question 2

Key value of aws

Answer 2

Pay for what you need

Question 3

What is a client?

Answer 3

A client is a web browser/desktop application that a person interacts with to make requests to computer servers.

Question 4

What is a server?

Answer 4

A server can be services such as Amazon Elastic Compute Cloud (Amazon EC2)

Question 5

What is cloud computing?

Answer 5

On-demand delivery of IT resources and applications through the internet with pay as you go pricing.

Question 6

What is another name for on-premises deployment?

Answer 6

Private cloud deployment

Question 7

What are the three cloud computing deployment models?

Answer 7

Cloud-based
On-premises
Hybrid

Question 8

Cloud-based

Answer 8

Run all parts of the application in the cloud.
Migrate existing applications to the cloud.
Design and build new applications in the cloud.

Question 9

On-premise

Answer 9

Deploy resources by using virtualization and resource management tools.
Increase resource utilization by using application management and virtualization technologies.

Question 10

Hybrid

Answer 10

Connect cloud-based resources to on-premises infrastructure.
Integrate cloud-based resources with legacy IT applications.

Question 11

Amazon EC2

Answer 11

provides secure, resizable compute capacity in the cloud as Amazon EC2 instances.

Question 12

Benefit of Amazon EC2

Answer 12

You can provision and launch an Amazon EC2 instance within minutes.
You can stop using it when you have finished running a workload.
You pay only for the compute time you use when an instance is running, not when it
is stopped or terminated.
You can save costs by paying only for server capacity that you need or want

Question 13

How Amazon EC2 works?

Answer 13

Launch, Connect and Use

Question 14

Amazon EC2 instance types

Answer 14

General Purpose
Compute Optimized
Memory Optimized
Accelerated computing instances
Storage optimized instances.

Question 15

General Purpose

Answer 15

General purpose instances provide a balance of compute, memory, and networking resources. You can use them for a variety of workloads, such as:
web servers
code repo

Question 16

Compute optimized instances

Answer 16

are ideal for compute-bound applications that benefit from high-performance processors. Like general purpose instances, you can use compute optimized instances for workloads such as web, application, and gaming servers.
hpc
scientific modelling

Question 17

Memory optimized instances

Answer 17

are designed to deliver fast performance for workloads that process large datasets in memory. In computing, memory is a temporary storage area

Question 18

Accelerated computing instance

Answer 18

use hardware accelerators, or coprocessors, to perform some functions more efficiently than is possible in software running on CPUs. Examples of these functions include floating-point number calculations, graphics processing, and data pattern matching.

Question 19

Storage optimized instances

Answer 19

are designed for workloads that require high, sequential read and write access to large datasets on local storage. Examples of workloads suitable for storage optimized instances include distributed file systems, data warehousing applications, and high-frequency online transaction processing (OLTP) systems.

Question 20

on demand

Answer 20

On-Demand Instances are ideal for short-term, irregular workloads that cannot be interrupted. No upfront costs or minimum contracts apply. The instances run continuously until you stop them, and you pay for only the compute time you use.

Question 21

Amazon EC2 Savings Plans.

Answer 21

enable you to reduce your compute costs by committing to a consistent amount of compute usage for a 1-year or 3-year term. This term commitment results in savings of up to 72% over On-Demand costs.

Question 22

Reserved Instances

Answer 22

For on-demand big discount
Require 1 -3 yr commitment

Question 23

Standard

Answer 23

Can change AZ, instance size (Linux), networking type

Question 24

convertible

Answer 24

Can change AZ, instance size, OS, payment options, have lower discount than standard

Question 25

Spot Instances

Answer 25

Spot Instances are ideal for workloads with flexible start and end times, or that can withstand interruptions.

90% saving. Cheapest but unreliable

Question 26

Dedicated Hosts

Answer 26

most expensive, physical server, can request location placement, not sharing hardware

per-socket, per-core, or per-VM software licenses to help maintain license compliance.

Question 27

Dedicated Virtual

Answer 27

virtual, cannot require location placement

Question 28

Infrastructure as a Service (IaaS)

Answer 28

Amazon Web Services

networking, computing, and data storage

Question 29

PaaS

Answer 29

no need to worry about infrastructure
(usually hardware and operating systems)

just focus on the deployment and management of your applications.

Amazon Lightsail
Amazon Elastic Beanstalk
Amazon GameLift
Amazon Relational Database Service (RDS)
Amazon Elastic Container Service (ECS)

Question 30

Software as a Service (SaaS)

Answer 30

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

end user apps like slack, dropbox
