This time, we will describe the features and functions of Fastly

Fastly CDN features

Fastly CDN works quickly by storing your website's content on servers around the world and quickly delivering that content to your users.
This uses
Varnish which makes sending that content (content objects) more efficient by automatically storing a copy in a temporary intermediate location. I'll make it.

Track each user's geographic location and ensure they are connected to the closest server.
This reduces the amount of time you have to wait for data to be sent from your server to your users, making your site faster.

You also have complete control over when and how content from your servers is stored.
set a time-to-live (TTL) on any path on your site and instantly disable or purge any path on your site using the Purge API

By using these tools, you only need to generate your site's pages once for millions of pageviews.
This reduces running costs related to user requests and server usage fees.

Fastly CDN features

Fastly CDN also provides many advanced features that help you monitor how your data is accessed and customize content delivery.

How Fastly CDN works

Fastly's CDN provides CDN services from major access points to the Internet, known as "POPs" (points of presence), where
connectivity to the Internet reduces network transit time when delivering content to end users. Quickly place POPs in locations.

that rapidly delivers content objects from the cache location closest to each end user when they are requested by an end user

Fastly's cache only receives and serves end-user requests for content objects such as:

■ Which objects to cache?
■ For how long and who can access them?
■ Whether objects are encrypted when sent over the Internet;
■ When to remove objects from the caching service, and so on.

Make these decisions by specifically configuring Fastly's CDN service using these requirements This configuration process is called "provisioning."

To provision Fastly's CDN service, you
need to identify the application servers that serve the original content objects for each of the various domains.

An application server
can be a physical server in a data center or hosting facility, an application running on a cloud service such as AWS or GCP, or any combination thereof.
Fast refers to these source servers interchangeably as "origin servers" and "backend servers."

summary

In addition to using your own servers as a source, Fastly's CDN
also supports using various cloud storage services as an origin, such as Amazon S3 and Google Cloud Storage (GCS).
