It’s been clear for a while that software designed explicitly for the data center environment will increasingly want/need to make different design trade-offs to e.g. general-purpose systems software that you might install on your own machines. The desire for CPU efficiency and lower latencies is easy to understand. Enter Google!

In order to be supported, a database is required to fulfill a set of features that are commonly available in systems like MySQL, PostgreSQL, MariaDB, and others. We want to support these systems as a source so that they can provide their data for further consumption. The database is sending them to a transport that DBLog can consume.

This enables customers to serve content to their end users with low latency, giving them the best application experience. In 2011, AWS opened a Point of Presence (PoP) in Stockholm to enable customers to serve content to their end users with low latency. As well as AWS Regions, we also have 24 AWS Edge Network Locations in Europe.

Last week we learned about the [increased tail-latency sensitivity of microservices based applications with high RPC fan-outs. Seer uses estimates of queue depths to mitigate latency spikes on the order of 10-100ms, in conjunction with a cluster manager. So what we have here is a glimpse of the limits for low-latency RPCs under load.

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).

Tools and CI systems help them monitor progress & prevent regressions. Some systems show median RTTs near ~100ms for 3G users. Contended, over-subscribed cells can make “fast” networks brutally slow, transport variance can make TCP much less efficient , and the bursty nature of web traffic works against us.

Finally, not inlining resources has an added latency cost because the file needs to be requested. As discussed in part 2 , in HTTP/2, this multiplexing is steered using its prioritization system. As also explained in part 2 , HTTP/3 fundamentally changes the internals of this prioritization system.
