Module 1 - Introduction to Amazon Web Services

Question 1

AWS Range of Services

Answer 1

1. Compute, storage, network security tools.
2. Complex solutions: blockchain, machine learning, artificial intelligence, robot development platforms.
3. Specialised tool sets like video production management systems, orbital satellites.

Question 2

Fundamental Cloud Compute Model

Answer 2

1. Client-server model.

2. AWS: Amazon Elastic Compute Cloud, EC2, EC2 instance, virtual server.

Question 3

Client-Server Model

Answer 3

A transaction between a client and a server. Server evaluates the details of this request and fulfils it by returning the information to the client.

Question 4

Client

Answer 4

Web browser or desktop application that person interacts with to make requests to computer servers.

Question 5

Server

Answer 5

Server evaluates details of request and fulfils it by returning the information to the client.

Question 6

Cloud Computing

Answer 6

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

Question 7

Three Cloud Computing Deployment Models

Answer 7

1. Cloud-based.
2. On-premises.
3. Hybrid.

Question 8

Factors for selecting cloud strategy

Answer 8

1. Required cloud application components.
2. Preferred resource management tools.
3. Legacy IT infrastructure requirements.

Question 9

Cloud-Based Deployment

Answer 9

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

NB:
1. can build on low-level infrastructure that requires IT staff to manage.

2. use higher-level services that reduce the management, architecting and scaling requirements of the core infrastructure.

Question 10

On-Premises Deployment (Private cloud deployment)

think resources

Answer 10

1. Deploy resources by using virtualisation and resource management tools.
2. Increase resource utilisation by using application management and virtualisation technologies.

(Might have applications that run on technology that is fully kept on-premises data centre).

Question 11

Hybrid Deployment

Answer 11

Connect cloud-based resources to on-premises infrastructure.

Question 12

Benefits of Cloud Computing (6)

TSSBIG

Answer 12

1. Trade upfront expense for variable expense.
2. Stop spending money to run and maintain data centres.
3. Stop guessing capacity.
4. Benefit from massive economies of scale.
5. Increase speed and agility.
6. Go global in minutes.

Question 13

Trade upfront expense for variable expense

Answer 13

Taking cloud computing approach that offers benefit of variable expense: companies can implement innovative solutions while saving on costs.

Question 14

Upfront expense

Answer 14

data centres, physical servers, other resources that you would need to invest in before using them.

Question 15

Variable expense

Answer 15

Only pay for computing resources you consume.

Question 16

Stop spending money to run and maintain data centres

Answer 16

Ability to focus less on spending more money and time managing infrastructure and servers and more on your applications and customers.

Question 17

Stop guessing capacity

Answer 17

Don’t have to predict how much infrastructure capacity you will need before deploying application. Also scale in or scale out in response to demand.

Question 18

Benefit from massive economies of scale

Answer 18

1. Achieve a lower variable cost than you can get on your own.
2. Usage from hundreds of thousands of customers can aggregate in the cloud.
3. Economy of scale translates into lower pay-as-you-go prices.

Question 19

Increase speed and agility

Answer 19

1. flexibility of cloud computing makes it easier for you to develop and deploy applications.
2. more time to experiment and innovate.
3. cloud computing enables you to access new resources within minutes.

Question 20

Go global in minutes

Answer 20

1. Global footprint of the AWS Cloud enables you to deploy applications to customers around the world quickly.
2. Low latency - customers access applications with minimal delays.
