18. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved. CAP Theorem Consistency Availability Partition Tolerance Data is consistent. All nodes see the same state. Every request is non-failing. Service still responds as expected if some nodes crash or get isolated. Distributed System In the presence of a network partition, you must choose between consistency and availability!
19. © 2019, Amazon Web Services, Inc. or its affiliates. All rights reserved. Embrace eventual consistency … if no new updates are made to a given data item, eventually all accesses to that item will return the last updated value. Availability An eventually consistent system can return any value before it converges!! https://en.wikipedia.org/wiki/Eventual_consistency Distributed System Every request is non-failing.
