Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How does Content delivery/distribution network work?
The LARGE majority of CDNs use either Apache Traffic Server (https://trafficserver.apache.org/) or Nginx for their cache webserver, so the mechanisms used are pretty easy to find if you look through the docs.

Using Nginx as an Object Storage Gateway
Apache Traffic Server (no relation to Apache itself) would be an excellent option: https://trafficserver.apache.org/

Apache Traffic Server
Although haproxy and nginx cover (for me) almost all use-cases I had to deal with (with OpenResty [1] as a backup), I see one place where ATS could shine: plugins. From examples [2], C API looks sane and well documented, and this is very important if you want to add some custom stuff inside your proxy server without losing your hair. And no, lua isn't the solution here ;)
Those who had to deal with nginx plugins, I feel your pain...

Varnish Cache
Varnish Cache is a tool that provides a caching HTTP reverse proxy in order to accelerate your web applications. Once Varnish Cache is installed in front of any server that understands HTTP and configured to cache the contents, delivery speeds are typically enhanced by a factor of 300-1000x, depending on architecture. Kilobyte22 finds this tool along with HAProxy to be a winning combo.

Leveraging Cache to improve Web Performance
In this case, caching mechanism is situated in the proxy server or reverse proxy server like Nginx, Apache, or Varnish, and most probably it is a part of ISP (Internet Service Provider).

Beyond Changing Technology: Scaling Your Applications Efficiently
To handle this level of traffic, you can use tools such as Varnish HTTP Cache, which caches the information of a news article starting from the first user who accesses and makes the request. Once Varnish caches the page, subsequent users will receive a response that is saved in memory. This process allows you to avoid unnecessary synchronous requests and send a quick response to users.

Web resource caching: Server-side
A couple of dedicated server-side resource caching solutions have emerged over the years: Memcached, Varnish, Squid, etc. Other solutions are less focused on web resource caching and more generic, e.g., Redis or Hazelcast.

Microfrontends: Microservices for the Frontend
Edge Side Includes (ESI): a more modern alternative to SSI. ESI can handle variables, have conditionals, and supports better error handling. ESI is supported by caching HTTP servers such as Varnish.

I NEED YOUR HELP WITH MY INTERNSHIP PROJECT
For this objective, I am looking for willing volunteers to run through two phases of test deployments. These phases will each involve creating a scalable Varnish Cache cluster on Azure Kubernetes Service and answering a few questions about your experience. The deployments should take a total of around 30 min (or less) and will require the creation of a very minimal Kubernetes cluster. For some more information on Varnish Cache check out: https://varnish-cache.org/

NGINX + Laravel way too slow when serving static files - Can you point me in the right direction?
Others have pointed out some very valid issues. A quick hack, try using Varnish Cache (https://varnish-cache.org/), you can really accelerate the static content delivery.
