Hello, everyone!
This blogpost will be about serverless computing.
So, what is serverless? The truth is, there is no server-less inside serverless, its all handled by servers. The only thing serverless means, is that its infinetly scalable, therefore the website will not become more laggy(atleast the serverless part wont), as the userbase grows.

The way it works is that you can commonly create something called serverless functions, which are functions that are ran each time a request it sent. For example, you can make a serverless function that will return you some dynamic content, such as current time, some value in a database, etc., because it doesn't have to be dynamic.
Serverless functions however can't rely on the other instances directly, because then they couldn't easilly run in paralel, and would need to wait for eachother, which is really pricy. Thats because the common pricing model for these functions is how many milliseconds did it took to run a requests times how many requests.

You can also use a CDN(content delivery network), to speed up the delivery of the data. Content delivery networks have bunch of servers all around the world, and each time user makes a request, you can serve them the data from their nearest edge server, making it faster than just hosting an ftp or http file server somewhere, and then serving all users from the same location.
The same applies to serverless functions, because they also have edge servers in a bunch of places around the world, so if the CDN/Serverless locations kindof cover eachother, you might be getting really low ping, which is great for a website, and other services.

That will be all for today, see you next time!
