A distinctive feature of the EOS platform is its possibility of horizontal scaling of decentralized applications, which allows creating high - performance Dapps. (coinfox.info)
My subfield of atmospheric and oceanic sciences is large - scale atmospheric dynamics — basically the fluid mechanics of atmospheric flows with horizontal scales of hundreds to thousands of kilometers (on Earth and Mars, at least). (geosci.uchicago.edu)
To help you better understand scaling, let's look at the difference between vertical and horizontal scaling before jumping into a couple of common scenarios... (jonloomer.com)
