System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?

Zero-knowledge databases

Zero knowledge databases

The idea

The idea is to provide a database as a service to end users in such a way that no one except the user herself can access the data, not even the hosting provider or the database administrator.

Advantages

  • A privacy- and/or security-conscious user will have more trust in such a setup.
  • The service provider cannot be coerced to release the data they were trusted with, and he cannot be held responsible for the content he is storing.
