Q

What is an example of Elastic Load Balancing?

A

Ensuring that no single Amazon EC2 instance has to carry the full workload on its own.

Elastic Load Balancing is the AWS service that automatically distributes incoming application traffic across multiple resources, such as Amazon EC2 instances. This helps to ensure that no single resource becomes overutilized.

Q

EC2 instance type 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.

17
Q

What are the four key factors to use when choosing an AWS Region?

A

Compliance
Proximity
Feature availability
Pricing

18
Q

A distinct location within a Region that’s insulated from failures and provides inexpensive, low-latency network connectivity within the same Region.

A

Availability Zone

19
Q

Uses a network of edge locations to cache content and deliver content to customers all over the world.

A

Amazon Cloudfront

An AWS content delivery service that helps you improve the performance, reliability, and availability of your websites and applications.

20
Q

A

Route 53

21
Q

A fully managed service that extends AWS infrastructure, APIs, and tools to customer premises

A

Amazon Outposts

22
Q

Web-based interface for accessing and managing AWS services

A

AWS Management Console

You can quickly access recently used services and search for other services by name, keyword, or acronym. The console includes wizards and automated workflows that can simplify the process of completing tasks.

23
Q

A graphical interface to manage compute, storage, and other cloud resources.

A

AWS Management Console

You can quickly access recently used services and search for other services by name, keyword, or acronym. The console includes wizards and automated workflows that can simplify the process of completing tasks.

24
Q

A unified downloadable and configurable tool for managing AWS services. Control multiple AWS services from the command line and automate them through scripts.

A

AWS Command Line Interface (CLI)

By using AWS CLI, you can automate the actions that your services and applications perform through scripts. For example, you can use commands to launch an Amazon EC2 instance, connect an Amazon EC2 instance to a specific Auto Scaling group, and more.

25
Q

A web service for deploying and managing applications in the AWS Cloud without worrying about the infrastructure that runs those applications

A

AWS Elastic Beanstalk

26
Q

A service for writing or changing templates that create and delete related AWS resources together as a unit

A

AWS CloudFormation

27
Q

An elastic network populated by infrastructure, platform, and application services that share common security and interconnection.

A

Amazon Virtual Private Cloud (VPC)

Amazon VPC enables you to provision an isolated section of the AWS Cloud. In this isolated section, you can launch resources in a virtual network that you define. Within a virtual private cloud (VPC), you can organize your resources into subnets. A subnet is a section of a VPC that can contain resources such as Amazon EC2 instances.

28
Q

A connection between a VPC and the internet

A

Internet gateway (IGW)

You can think of an internet gateway as being similar to a doorway that customers use to enter the coffee shop. Without an internet gateway, no one can access the resources within your VPC.

29
Q

The component that allows protected internet traffic to access private resources in a VPC

A

Virtual private gateway

30
Q

A service that enables you to establish a dedicated private connection between your data center and a VPC

A

AWS Direct Connect

31
Q

Service that checks traffic entering and leaving a subnet

A

Access Control List (ACL)

ACLs are stateless - remembers nothing. They re-check when messages want to leave the subnet

32
Q

A virtual firewall that controls inbound and outbound traffic for an Amazon EC2 instance.

A

Security Group

Security Groups are stateful - they remember. They allow messages that are allowed in to automatically leave

33
Q

A section of a VPC in which you can group resources based on security or operational needs

A

Subnet

Public subnets contain resources that need to be accessible by the public, such as an online store’s website.

Private subnets contain resources that should be accessible only through your private network, such as a database that contains customers’ personal information and order histories.

34
Q

Dynamic scaling

A

Scaling that responds to changing demand

35
Q

Predictive scaling

A

Automatically schedules the right number of Amazon EC2 instances based on predicted demand
