Lecture 10: Leveraging the AWS Global Infrastrcture

Question 1

A ____________ is an application deployed in multiple geographies such as regions or edge locations. It also has decrease latency. It’s also used for attack protection and disaster recovery

Answer 1

Global Application

Question 2

• Global DNS: route 53
• Global content delivery network (CDN): cloudfront
• S3 transfer acceleration
• AWS global accelerator

Answer 2

What are the different global applications in AWS?

Question 3

_________ is a managed DNS (domain name system)

Answer 3

Route 53

Question 4

1. Simple routing policy - which has no health checks
2. Weighted routing policy- can distribute the traffic among multiple EC2 instances (using assigned weights on them)
3. Latency routing policy- redirect users to the closest server to reduce the latency
4. Failover routing policy- which is involved in the disaster recovery

Answer 4

What are the different types of route 53 policies?

Question 5

________ is a content delivery network (CDN) that improves read performance, and content is cached at the edge

Answer 5

CloudFront

Question 6

DDoS protection

Answer 6

CloudFront has _________ protection where it has integration with shield, AWS web application firewall

Question 7

• S3 buckets
• Custom Origin (HTTP)

Answer 7

What are the different cloudfront origins?

Question 8

Cloudfront is great for static content that must be available everywhere and S3 cross region replication is great for dynamic content that needs to be available at low-latency in a few regions

Answer 8

What is the difference between cloudfront and S3 cross region replication?

Question 9

_______ increase transfer speed by transferring file to an AWS edge location which will forward the data to the S3 bucket in the target region

Answer 9

S3 Transfer acceleration

Question 10

__________ is used to improve global application availability & performance using the AWS global network and is used to leverage the AWS internal network to optimize the route to your application

Answer 10

Global accelerator

Question 11

Global accelerator

Answer 11

With ________ 2 anycast IP are created for your application and traffic is sent through edge locations

Question 12

Cloudfront improves performance for your catchable content and its content is served at the edge whereas global accelerator is no catching procuring pockets at the edge to application runnings in one or more aws regions

Answer 12

What is the difference between global accelerator and cloudfront?

Question 13

_________ are infrastructure deployments embedded within the telecommunications providers data centers at the edge of the 5G networks

Answer 13

WaveLength

Question 14

_________ are placed AWS compute, storage, database, and other selected AWS services closer to end users to run latency-sensitive application its also involved in “extension of AWS region”

Answer 14

Local Zones

Question 15

Mean you have two regions and each regions has 1 or multiple AZ and in one regions your application will be active which means users can do read and writes to ur EC2 in active region and in the other region the instance is passive which means they can do read but not writes

Answer 15

What does active, passive mean?

Question 16

What are the features of active-passive?

Answer 16

-Has improved read latency
-Has less improved global writes latency
-Little difficult since you have multiple regions

Question 17

What are the features of active-active?

Answer 17

-Has improved read and write latency
-It has high difficulty

Question 18

________ is an AWS Infrastructure offering optimized for mobile edge computing applications.
___________ combines the high bandwidth and ultra-low latency of 5G networks with AWS compute and storage services to enable developers to innovate and build a whole new class of applications.

Answer 18

Wavelengths

Question 19

_________ bring native AWS services, infrastructure, and operating models to virtually any data center, co-location space, or on-premises facility.

Answer 19

AWS Outpost

Question 20

Domain Registration

Answer 20

Route 53 features are (non exhaustive list): ___________, DNS, Health Checks, Routing Policy
