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?

  # Construct a link to +url_fragment+, which should be given relative to
  # the base of this Sinatra app.  The mode should be either
  # <code>:path_only</code>, which will generate an absolute path within
  # the current domain (the default), or <code>:full_url</code>, which will
  # include the site name and port number.  The latter is typically necessary
  # for links in RSS feeds.  Example usage:
  #
  #   link_to "/foo" # Returns "http://example.com/myapp/foo"
