Yes, DDIA is the bible for this stuff with regards to getting a good overview to modern practices.

There's also good resources here, even though it is interview oriented: https://github.com/checkcheckzz/system-design-interview

Highly recommended as well. Kudos to Martin; not only is it excellently written and dense in information, each chapter has a fantastic reference section which can lead you to more interesting resources, papers and books.
