To ensure low-latency and high availability (or even just the ability to work when offline) we want to be able to operate locally and independently on data types. composable) data type definitions, and in the process, ascribe to them a meaningful and useful distributed semantics. Local operation, global coordination.

At the end of the day, you get the dual benefit of higher throughput and lower latency (as compared to coordination-based approaches) coupled with knowing that there isn’t some nasty invariant-violating concurrency bug waiting to bite you (so long as you specified your invariants and operation effects correctly of course!).

This kind of approach is although a victim of latency and delayed execution. No matter what kind of cloud-based tool you are using, the latency is bound to happen since there are too many requests involved in between. Although these kinds of issues are nothing in front of infrastructure maintenance.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).
