Postel's Law

Be conservative in what you send, be liberal in what you accept

CAP Theorem

It is impossible for a distributed computer system to simultaneously provide all three of the following guarantees:

• Consistency (all nodes see the same data at the same time)
• Availability (a guarantee that every request receives a response about whether it succeeded or failed)
• Partition tolerance (the system continues to operate despite arbitrary message loss or failure of part of the system)

How big should a service be?
