What are the minimum tech specs required (RAM / Storage / Processing / Other) for each of the three servers in the “three server setup” below in order to efficiently handle “around 10 million hits a day”?
The Django Book, in the section about “scaling Django”, says:
At this point, we’ve broken things down as much as possible. This three-server setup should handle a very large amount of traffic – we served around 10 million hits a day from an architecture of this sort – so if you grow further, you’ll need to start adding redundancy.
Their diagram looks like this.
I am in the middle of getting this three server setup going on Digital Ocean with Ubuntu 16.04, and I was curious, does anyone have any insight into the assumed tech specs for each of these servers? Presumably the media server needs less than the database and Django server, unless it is heavily reliant on serving media content.
For context, my web application will use Nginx and Postgres and I can expect the data in the database to change quite often as the user interacts with the site.
