Wikipedia defines a distributed system as a “software system in which components located on networked computers communicate and coordinate their actions by passing messages.”
In modern world, more and more systems become distributed. Yet, surprisingly few authors write about practical architecture of distributed systems. As our Hare have architected all kinds of distributed systems, from a stock exchange to a billion-messages-a-day game, we’re in a very good position to fill this gap.
| Quote: | “it is DB which is usually The Bottleneck™ – it means that we’re saving this enormous amount of load, exactly where it really matters.” |
| Another Quote: | “as discussed above, the real-world task is always about scaling the whole system, including database; and in this regard Stateless-App-based systems exhibit significant problems.” |

| Quote: | “to make an efficient representation usable for OLAP – we need to modify our data on its way to OLAP replicas” |
| Another Quote: | “Each of the DB Server Apps is a replica master, but all replica targets are within the same Replica DB” |

| Quote: | “Then you can recover from any single server failure in a perfectly transparent manner” |
| Another Quote: | “after the program fails in production, we can get the input log and run it in the comfort of a developer’s machine, under a debugger, as many times as we want, and get exactly the same variables at exactly the same points as happened in production” |

| Quote: | “I am not saying that this architecture is the only viable one, but it does work for TCP for sure (and performs reasonably well too)” |
| Another Quote: | “The whole task of optimizing performance beyond, say, 20-50K packets/second per box tends to be Quite Elaborated, and involves quite a few things which are platform- and hardware-dependent.” |

| Quote: | “Modifying generated code usually qualifies as a Really Bad Idea” |
| Another Quote: | “How much can be gained by each of such specialized encodings – still depends on the game, but if you can try-and-test a dozen of different encodings within a few hours – it will usually allow you to learn quite a few things about your traffic (and to optimize things both visually and traffic-wise too).” |

| Quote: | “In other words, you can write your code ‘as if’ all-your-code-within-the-same-FSM executed within the same thread” |
| Another Quote: | “As soon as we have these two parts of processing – we can say that our Server-to-Server communication is tolerant to all kinds of transient inter-server disconnects” |
