Leader Election
Similar to the transaction example:
Leader acquires lock
Leader does something
Leader releases lock
Watch key-value for changes (leaders and followers!):
Leader steps down
Leader fails (including false positives)

Summary
consul io:
Simple but very powerful!
Makes distributed systems development easy!
Very fun to work with!
Unfortunately, it is still a bit "edge" :'(
But future looks promising ;)
