What is the difference between the Yocto and Raspbian?

Question

Recently I come to about the IIoT solution of siemens which have Yocto Linux https://www.14core.com/siemens-simatic-iot2000-iot2020-iot2040-arduino-ide-integration/. As I am already working on raspberry pi and raspberry pi based Revolution Pi known as RevPi which uses raspbian based OS .here you will find the use full information about the RevPi https://revolution.kunbus.com.

I don't have much knowledge about these Linux based open-source Operating System. Can anyone help me to understand in what aspect Yocto Linux is different from Raspbian OS?

Answer 1

There is a good whitepaper here which describes in detail the differences between Yocto and Debian(Raspbian is a flavor of Debian).

From the whitepaper, the gist is:

Debian is good for fast trials, proof of concept and desktop like environments on hardware already supported by Debian with large memories and limited requirements for maintenance, traceability and reuse across different hardware targets.

and

Yocto is good for customized embedded environments with various hardware support and small to large memories and requirements for maintenance, traceability, longevity and reuse across difference hardware targets.
