Skype developers will come to HL ++

In order to exchange experience with our Western colleagues, we expect guests from Skype - the largest company providing voice services over the Internet. The Skype user directory is distributed across the computers of the Skype network users, which allows the network to easily scale to very large sizes (five to ten million users online) without expensive infrastructure of centralized servers.



Thanks to Skype, Internet telephony has become widespread - over 350 million users now use Skype.



The Postgresmen company brings two Skype developers to the HighLoad ++ conference at once. Asko Oja, a leading database specialist, will read the report on Skype Distributed Database Architecture.

This is what Asko says about the report: “The report describes how we scaled the Skype database running PostgreSQL from one server to the current huge system with hundreds of servers and tables containing billions of records capable of processing tens of thousands of queries per second. . We will talk about the tools that were developed for this and published under an open license: plProxy for remote stored procedure calls and scaling, SkyTools for queuing, replicating and building fault-tolerant systems, pgBouncer for managing connections and caching them. Almost all of these tools can be useful in much smaller systems. ”



The second specialist, Marko Kreen, works as a simple engineer on Skype and is also the coolest hacker, developing and maintaining such well-known PostgreSQL projects as PL / Proxy, Skytools, PgBouncer and pgcrypto.



The goal of our conference is the professional growth of each of its participants and, no doubt, the experience of companies such as Skype will be useful to Russian developers. I invite Habrovchan - October 6 and 7, Moscow .
