Global Infrastructure Flashcards
Global Application
Deployed in multiple geographies
Benefit of Global Application
Lower latency
Better experience
DR
Route53
DNS
CloudFront
CDN
Replicate applications to AWS Edge Locations
S3 Transfer Acceleration
Accelerate uploads and downloads to S3
Route 53 Weighted Routing Policies
Load balancing through DNS
Latency Routing Policy
Routes DNS traffic based on users latency
Failover Routing Policy
DNS performs health checks and fails over
How does Cloudfront lower latency?
Apps cached globally
216 points of presence
Cloudfront security benefit
DDOS protection
WAF
Cloudfront Origin services (2)
S3
HTTP
Cloudfront vs. S3 Cross Region Replication
Cloudfront uses Global Edge and Cache
S3 CRR must be set up for each region
S3 Transfer Acceleration
Transfers S3 files internally from one region to another
S3 Transfer Acceleration benefit
Faster transfers
AWS Global Accelerator
Internally route traffic between regions.
AWS Global Accelerator benefit
Improves availability and performance (60%)
Which AWS service uses 2 Anycast IP’s to connect to Edge locations?
AWS Global Accelerator
AWS Global Accelerator vs. Cloudfront
AWS Global Accelerator: Sends traffic through proxies to local Edge locations
Cloudfront: CDN that caches content
AWS Outposts
AWS hardware in your DC. (Racks)
Hybrid Cloud
Peloaded with AWS services
AWS outposts benefits
Local data processing
Data residency
Easier migration from on-prem to cloud
Fully managed (except physical security)
AWS Wavelength
Deploy AWS services to 5G edge
AWS local zones
Extend AZ’s into local regions
Global App Architecture types (2)
Active-Active
Active-Passive
Active-Passive Region
One region is Active (read-write)
The other region is passive (replication and read only)
Active-Active Regions
Multiple regions with read and write
Replication
What two services does CloudFront use to protect against attacks?
