AWS-Module 1 Material

Question 1

What is AWS and what does it provide?

Answer 1

AWS stand for amazon web services & AWS provides on-demand delivery of technology services through the Internet with pay-as-you-go pricing. This is known as cloud computing.

Question 2

Almost all modern cloud computing centers around a basic __________ model (a customer makes a request & the server responds to that request

Answer 2

client-server

Question 3

What is the Client sever model?

Answer 3

In computing a client can be a web browser or desktop application that a person interacts with to make requests to computer servers. A server can be service, such as Amazon Elastic Compute Cloud (Amazon EC2) (a type of virtual server)

Question 4

What is this example of? When a request is made the sever evaluates the request & then fulfill it by returning the information to the client

Answer 4

Client server model

Question 5

What is Amazon elastic cloud (EC2 Sever)

Answer 5

Its a web service that provides secure, resizable computing capacity in the cloud. It is designed to make web-scale computing easier for developers.

web service interface allows you to obtain and configure capacity with minimal friction.

Question 6

With AWS what type of pricing do they do?

Answer 6

pay-what- you use pricing (only pay for what you used, don’t need to prepaid or anything like that) (So if you need more capacity you don’t prepaid for it & if you don’t need all that capacity then you simply removed it)

Question 7

What is Cloud computing? And why do companies use it?

Answer 7

is the on-demand delivery of IT resources over the internet with pay-as-you -go pricing (provides developers and IT departments with the ability to focus on what matters most and avoid undifferentiated work such as procurement, maintenance, and capacity planning.)

Question 8

On-demand -delivery means what?

Answer 8

indicates a service like AWS has the resources you need when you need them (don’t need to notify in advance that your going to need them)(ex. Like you need 300 sever, just a few click & launch them)

Question 9

AWS provides alot of ________ resources because it understand so many business need them

Answer 9

IT Resources

Question 10

How does AWS Undifferentiated heavy lifting of IT?

Answer 10

AWS wants task that are repetitive, time-comsuming, common, it wants to help you with so you can focus on what makes you unique

Question 11

What does Over the internet mean?

Answer 11

you can access those resources using a secure web page consol or program (no initial contracts or ales are needed)

Question 12

What are the 3 different cloud computing deployment models?

Answer 12

1. Cloud-base deployment
2. On-premises deployment
3. Hybrid deployment

Question 13

Cloud-base deployment

Answer 13

you can migrate existing application to the cloud or you can design and build new application in the cloud, using a public cloud infrastructure

Question 14

What are some key features of cloud based deployment model?

Answer 14

• You can build those applications on low-level infrastructures that require IT staff to manage them or you can build them using high-level services that reduce management, architecting, and scaling requirements of the core infrastructure
• Run all parts of the application in the cloud
• Migrates existing applications to the cloud
• Design & build new applications in the cloud

Question 15

On-premises deployment (private cloud deployment)

Answer 15

resources are deployed on premises by using virtualization & resource management tools

Question 15

In this example what type of cloud-computing deployment would a company use? : a company might create an application consisting of virtual servers, databases, and networking components that are fully based in the cloud.

Answer 15

Cloud-based deployment model

Question 16

What are some key features of on-premises deployment?

Answer 16

-Deploy resources by using virtualization & resource management tools

-Increase resource utilization by using application management & virtualization technologies

Question 17

What type of cloud-computing deployment was used in this example? : you might have applications that run on technology that is fully kept in your _____________data center. Though this model is much like legacy IT infrastructure, its incorporation of application management and virtualization technologies helps to increase resource utilization.

Answer 17

On-premises deployment (private cloud deployment)

Question 18

Hybrid deployment

Answer 18

cloud-based resources are connected to on-premises infrastructure, you could use this approach in a variety of situations

( For example, you have legacy applications that are better-maintained on-premises, or government regulations require your business to keep certain records on premises.)

Question 19

What are some key features of the hybrid deployment model?

Answer 19

-Connect cloud-based resources to on-premises infrastructure

-Integrates cloud-based resources with legacy IT applications

Question 20

What cloud deployment model was used in this example? : suppose that a company wants to use cloud services that can automate batch data processing and analytics. However, the company has several legacy applications that are more suitable on premises and will not be migrated to the cloud. With a _______, the company would be able to keep the legacy applications on premises while benefiting from the data and analytics services that run in the cloud

Answer 20

Hybrid deployment

Question 21

What are some benefits of cloud computing?

Answer 21

-Trade upfront expense (data centers, physical center, etc) for the variable expense (variable expense means you only pay for what you use), which can save them money while trying innovative solutions

-Stop spending money to run & maintain data centers ( can focus less on tasks like spending money, managing infrastructure & servers & focus on customers & applications)

-Stop guessing capacity- you don’t need to produce how much infrastructure capacity you will need before deploying an application
Benefit from massive economies of scale- can get lower variable cost than you would get on your own

-Increase speed & agility- the flexibility of cloud computing makes it easier for you to develop & deploy applications

-Go global in minutes- the global footprint of AWS enables you to deploy applications to customers around the world quickly while providing them with low latency

Question 22

What are the 3 different types of cloud computing models?

Answer 22

1. Infrastructure as service (IaaS)
2. Platform as a service (PaaS)
3. Software as a service (SaaS)

Question 23

Infrastructure as a service (IaaS)

Answer 23

contains the basic building blocks for cloud IT & typically provides access to networking features, computers (virtual or on dedicated hardware), & data storage space. It provides you with the highest level of flexibility & management control over your IT resources & is most similar to existing IT resources that IT department & developers are familiar with

is a type of cloud computing service that offers essential compute, storage, and networking resources on demand, on a pay-as-you-go basis.

Question 24

Platform as a Service (PaaS)

Answer 24

removes the need for your organization to manage the underlying infrastructure (usually hardware & operating systems) & allows you to focus on the development & management of your applications

is a cloud computing model where a third-party provider delivers hardware and software tools to users over the internet

Question 25

Software as a Service (SaaS)

Answer 25

provides you with a completed product that is run & managed by the service provider, usually refers to end-user applications. With SaaS, you don’t have to think about how the service is maintained or how the underlying infrastructure is managed, just focus on how you will use the software (ex. web-based email which you can use to send and receive email without having to manage feature additions to the email product or maintain the servers and operating systems that the email program is running on.)

is a way of delivering applications over the Internet—as a service. Instead of installing and maintaining software, you simply access it via the Internet, freeing yourself from complex software and hardware management.
