Fastly CDN Features
Fastly CDN works quickly by storing website content on servers around the world and delivering that content to users rapidly.
, an open-source web application acceleratorVarnishuses
to make the transmission of content (content objects) more efficient by automatically saving temporary copies in intermediate locations.
We track each user's geographical location and ensure they are connected to the nearest server.
This reduces the time it takes for data to be sent from the server to the user, resulting in a faster site.
Furthermore, you have complete control over when and how content is stored from your server.
You can set a Time To Live (TTL) for any path on your site andthe Purge API instantly invalidate or purge any path on your site using
By using these tools, you only need to generate your site's pages once for millions of page views.
This reduces the running costs associated with user requests and server usage.
Fastly CDN features
Fastly CDN also offers many advanced features that help you monitor how your data is accessed and customize content delivery
| ● Instant Purging | You can have better control over when and how your content is updated. Instead of waiting up to 24 hours for data to change at the edge, you can update your data when and as often as you need to. |
| ● Real-Time Analytics | We provide a top-level view of your network and site performance. We compile relevant data on all traffic, every second, into easy-to-read reports. |
| ● Conditions | It changes how requests are routed, what headers are sent, and how content is cached |
| Health Checks | If there's a problem with your server, you'll know about it immediately |
| ● Streaming Log | It can be quickly and easily configured to send information from your server to anywhere, in the format you need |
| ● Varnish Configuration Language (VCL) | You can modify almost every aspect of HTTP requests and responses. You can upload special configuration VCL files to your account |
| Fastly API | Fastly exposes an API that allows you to handle programmatic configuration, allowing you to write scripts to handle basic configuration tasks and create your own admin views |
How Fastly CDN works
Fastly's CDN provides CDN services from major access points to the internet, known as "POPs (Points of Presence)," and
quickly places these POPs in locations where network transit time is reduced when delivering content to end users, thanks to the internet connection.
Each POP has a cluster of Fastly cache servers that, when an end user requests a content object,
quickly deliver the content object from the cache location closest to each end user.
Fastly's cache only receives and serves end-user requests for content objects that:
■ Which objects to cache
■ For how long and who can access them
■ Whether to encrypt objects when sending them over the internet
■ When to remove objects from the cache service ...and so on.
by specifically configuring Fastly's CDN service using these requirements
. We call this configuration process "provisioning".
To provision Fastly's CDN service,
you need to identify the application server that will serve the original content objects for each different domain.
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 of these.
These source servers are referred to as "origin servers" and "backend servers" in the same sense.
summary
in addition to using your own servers as sources
supports using various cloud storage services, such as Amazon S3 and Google Cloud Storage (GCS), as origins,
