What is the primary purpose of Amazon CloudFront?

Amazon CloudFront is designed to deliver content to end-users with lower latency by utilizing a global network of edge locations.

How many edge locations does Amazon CloudFront have worldwide?

As of the time of the transcript, Amazon CloudFront has over 410 edge locations in more than 200 cities across 47 countries.

What is the benefit of having a global network of edge locations for CloudFront?

The global network of edge locations allows CloudFront to cache and serve content from the nearest location to the end-user, reducing latency and improving load times.

What is the new feature called 'Shield' that was added to CloudFront?

Shield is a feature that helps reduce the load on origin servers by caching content at edge locations, which can improve performance and reduce costs.

How does CloudFront handle requests when there is a flash crowd or a sudden surge in traffic?

CloudFront has a mechanism to distribute the load among multiple edge locations, which helps to reduce the risk of overloading the origin server.

What is the concept of 'Origin Failover' in CloudFront?

Origin Failover is a feature that allows users to specify a primary and secondary origin server. If there is an error connecting to the primary server, CloudFront will automatically route the request to the secondary server.

What is the function of 'Lambda@Edge' in the context of Amazon CloudFront?

Lambda@Edge allows users to run Lambda functions (compute logic) at the edge locations of CloudFront, enabling real-time processing of requests and responses.

How can CloudFront help with security measures?

CloudFront can integrate with AWS WAF (Web Application Firewall) to help protect web applications from various types of attacks, and it supports SSL/TLS to secure the connection between the client and CloudFront.

What is the 'Real-time Log Streaming' feature in CloudFront?

Real-time Log Streaming allows users to collect and analyze access logs from CloudFront's edge locations in near real-time, which can be useful for monitoring and troubleshooting.

How can users customize error responses in CloudFront?

CloudFront allows users to customize error responses by defining custom error response pages that can be served when specific HTTP status codes are returned.

What is the 'Geo Restriction' feature in CloudFront?

Geo Restriction is a feature that lets users restrict access to their content based on the geographic location of the request, allowing them to control who can access their content.
