By definition, a distributed system is any system that comprises of multiple components on variety of machines that work together to appear as a single, organized system. Although the definition may seem straightforward, in the real-world, a distributed system is one of the most complex environments to understand, manage, and monitor.

In both cases, when using virtually-synchronous replication, the process will require certification from each node and local (by node) write; as such, the number of writes is NOT distributed across multiple nodes but duplicated.

This boils down to a single digit µs latency toleration in the tail for far memory, and in addition to security and privacy concerns, rules out remote memory solutions. Thus we’re fundamentally trading (de)-compression latency at access time for the ability to pack more data in memory.

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).

For example, you could reduce compression efficiency , because that works better with more data. Finally, not inlining resources has an added latency cost because the file needs to be requested. This retry process best happens, of course, somewhere before the back-end server — for example, at the load balancer.
