a) EC2
b) IAM
c) Lambda
d) Rekognition
b) IAM
IAM is a global service (encompasses all regions).
Which of the following is the definition of Cloud Computing?
a) Rapidly develop, test, and launch software applications
b) Automatic and quick ability to acquire resources as you need them and release resources when you no longer need them
c) On-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user
d) Change resource types when needed
c) On-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user
This is the definition of Cloud Computing
What defines the distribution of responsibilities for security in the AWS Cloud?
a) AWS Pricing Fundamentals
b) The Shared Responsibility Model
c) AWS Acceptable Use Policy
d) The AWS Management Console
b) The Shared Responsibility Model
The Shared Responsibility Model defines who is responsible for what in the AWS Cloud.
A company would like to benefit from the advantages of the Public Cloud but would like to keep sensitive assets in its own infrastructure. Which deployment model should the company use?
a) Private Cloud
b) Public Cloud
c) Hybrid Cloud
Using a Hybrid Cloud deployment model allows you to benefit from the flexibility, scalability and on-demand storage access while keeping security and performance of your own infrastructure.
c) Hybrid Cloud
What is NOT authorized to do on AWS according to the AWS Acceptable Use Policy?
a) Building a gaming application
b) Deploying a web site
c) Run analytics on stolen content
d) Backup your data
c) Run analytics on stolen content
You can run analytics on AWS, but you cannot run analytics on fraudulent content. Refer to the AWS Acceptable Use Policy to see what is not authorized to do on AWS.
What are the 5 characteristics of Cloud Computing?
- Is fully on-demand self service: users can provision resources and use them without human interaction from the service provider
- Broad network access: resources are available over the network, and can be accessed by diverse client platforms.
- Multi-tenancy and resource pooling: Multiple customers can share the same infrastructure and applications with security and privacy; multiple customers are serviced from the same physical resources.
- Rapid elasticity and scalability: Automatically and quckly acquire and dispose resources when needed; quickly and easily scale based on demand.
- Measured service: usage is measured, users pay for what they have used.
Mention the 6 advantages of Cloud Computing:
Trade capital expense for variable expense – Instead of having to invest heavily in data centers and servers before you know how you’re going to use them, you can pay only when you consume computing resources, and pay only for how much you consume.
Benefit from massive economies of scale – By using cloud computing, you can achieve a lower variable cost than you can get on your own. Because usage from hundreds of thousands of customers is aggregated in the cloud, providers such as AWS can achieve higher economies of scale, which translates into lower pay as-you-go prices.
Stop guessing capacity – Eliminate guessing on your infrastructure capacity needs. When you make a capacity decision prior to deploying an application, you often end up either sitting on expensive idle resources or dealing with limited capacity. With cloud computing, these problems go away. You can access as much or as little capacity as you need, and scale up and down as required with only a few minutes’ notice.
Increase speed and agility – In a cloud computing environment, new IT resources are only a click away, which means that you reduce the time to make those resources available to your developers from weeks to just minutes. This results in a dramatic increase in agility for the organization, since the cost and time it takes to experiment and develop is significantly lower.
Stop spending money running and maintaining data centers – Focus on projects that differentiate your business, not the infrastructure. Cloud computing lets you focus on your own customers, rather than on the heavy lifting of racking, stacking, and powering servers.
Go global in minutes – Easily deploy your application in multiple regions around the world with just a few clicks. This means you can provide lower latency and a better experience for your customers at minimal cost.
Problems solved by the cloud:
- Flexibility: change resource types when needed.
- Cost-Effectiveness: pay as you go, for what is used
- Scalability: accomodate larger loads by making hardware stronger or adding aditional nodes
- Elasticity: ability to scale out and scale-in when needed.
- High-availability and fault-tolerance: build across data centers
- Agility: rapidly develop, test and launch software applications.
