What does Amazon CloudFront enable?
Summary of the article:
Amazon CloudFront is a web service that enables the distribution of content with low latency and high data transfer rates. It consists of two main components: content delivery and dynamic content caching. CloudFront provides various advantages, including improved reliability and availability, high-level security, and quick content delivery through HTTP or HTTPS protocols. With CloudFront, users can perform actions such as updating and deleting distributions. CloudFront Functions is a feature that allows for lightweight, short-running functions, such as cache key normalization. Users can secure and restrict access to content by configuring HTTPS connections, blocking specific geographic locations, or requiring signed URLs or cookies. CloudFront can be integrated with various AWS services such as Amazon S3, Amazon EC2, and Elastic Load Balancing. Its purpose is to speed up the distribution of static and dynamic web content.

What is the purpose of CloudFront
Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users. CloudFront delivers your content through a worldwide network of data centers called edge locations.
Which of the following is not correct about CloudFront
The correct answer is option A (CloudFront cannot serve content from a non-AWS origin server). We can configure multiple origin servers for Amazon CloudFront. They can be either Amazon resources or non-AWS origin servers. So, we can use AWS resources for what it is meant for.
How do I know if CloudFront is being used
Sign in to the AWS Management Console and open the CloudFront console at https://console.aws.amazon.com/cloudfront/v3/home .In navigation pane, click Usage Reports.In the CloudFront Usage Reports pane, for Start Date and End Date, select the date range for which you want to display usage charts.
What types of distributions does CloudFront provide
AWS CloudFront supports two types of distributions: streaming and download. When a user requests static content with a CloudFront URL, the service finds the nearest edge location based on the request IP and caches the content in that location.
Why is Amazon CloudFront blocking me from websites
Request Blocked." is an error from the client. This error can occur due to the default actions of AWS WAF rules associated with the CloudFront distribution. The following settings might cause a Request Blocked error: When the default action is set to Allow, the request matches a rule that has Action set to Block.
What services can CloudFront retrieve content
If the content is not in that edge location, CloudFront retrieves it from an origin that you've defined—such as an Amazon S3 bucket, a MediaPackage channel, or an HTTP server (for example, a web server) that you have identified as the source for the definitive version of your content.
Why use CloudFront in front of API Gateway
The main reason to deploy a CloudFront distribution in front of an API Gateway endpoint is to reduce latency.
Which statement best describes Amazon CloudFront

Are CloudFront links safe
CloudFront can enforce secure end-to-end connections to origin servers by using HTTPS. Field-level encryption adds an additional layer of security that helps protect specific data throughout system processing so that only certain applications can see it.
Which service does CloudFront integrate with to protect against web
Amazon CloudFront is a highly secure CDN that provides both network and application level protection. All CloudFront customers benefit from the automatic protections of AWS Shield Standard, at no additional charge.
Do we need CloudFront for API Gateway

Which of the following use cases would benefit most from Amazon CloudFront
Amazon CloudFront is ideal for media and entertainment, gaming, social media, and many more use cases.
