Interacting with data using multiple servers?

Question

PHP

The task is following, I ask not to kick strongly for a question. Parsing, collection, and analysis of data will take place on one server. On another site that will display ready-made information. How to organize data exchange between servers, given that as soon as the data has arrived at the server where the parser is located and has been analyzed, they should immediately get to the main site. In what direction should we move in order to solve the problem?

Answer 1

Immediately after the analysis, write the data to the database, from where they can be read by the "main site".
When you connect to the database, you specify the address. So, you can write there not only localhost, it also works through the Internet.

Answer 2

See don't optimize ahead of time.
Inserting data is a relatively easy operation in relation to scraping and retrieving pages.
In addition, let's say you have a scraper, you give it a pack of addresses, it does something, then writes it to the database.
Writing to the database will be pretty fast.
