AWS CloudFront Edge Locations: Comprehensive Guide for AWS Solution Architect Exam
Edge Locations are an integral part of AWS CloudFront's content delivery network (CDN).
What are Edge Locations?
Edge Locations are sites that AWS has established worldwide in major cities. These locations serve as caching centers, storing copies of your data closer to end users to improve speed and decrease latency.
Importance of Edge Locations:
Speed and latency are crucial factors affecting customer satisfaction and engagement. By creating Edge Locations, AWS allows data be delivered to users quickly no matter where they are located, enhancing user experience.
How Edge Locations Work:
When user requests data, the request is routed to the Edge Location closest to the user. If the data is not available (cache miss), the edge location fetches it from the origin server and stores it for future access.
Exam Tips for Answering Questions on Edge Locations:
1. Understand differentiate between Edge locations and Regions or Availability Zones. They are not the same.
2. Know how cache behavior works. The behavior settings determine how CloudFront responds to requests.
3. Be familiar with CloudFront's automatic failover to a secondary location when primary edge location is unavailable.
4. Be aware that even after the data is deleted from the origin server, it might still be available in the edge location until its Time to Live (TTL) expires.

Edge locations practice test
Edge locations are data centers located in geographical regions near the end-users that cache content for faster access. They are the points of presence (PoPs) for AWS CloudFront, with each edge location connecting to the nearest AWS region. When a request is made for content, the nearest edge location serves the cached content. If the content is unavailable, CloudFront fetches it from the origin server-cache it at the edge location for future requests. Hence, edge locations play an essential role in reducing latency, increasing web performance, and optimizing traffic between regions and users.
