This tutorial shows how to set up a standalone storage server on Ubuntu 12.10. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Saving data on the client-side can help to speed up the performance of your web applications as it can reduce the number of database queries that are needed on the server. This frees up valuable server resources and can potentially even lead to reduced infrastructure costs.

MySQL Proxy transparently passes information between a client and a MySQL server. The proxy can audit the information flow in both directions and change it if necessary, which could be useful for protecting the MySQL server from malicious queries or for altering the information clients receive without actually making changes to the database. The proxy can also do load balancing between MySQL servers, and perform flow optimization by directing SELECT statements to read-only slave servers, which enhances MySQL scalability by allowing you to add more servers for read operations.

W dziale tym zajmę się programowaniem w C i C++ głównie dla Linuxa (ze względu na wykorzystywane funkcje systemowe tego systemu i testowanie w nim prezentowanych rozwiązań). Nie będzie to jednak typowe omówienie czy kurs tego języka, prócz krótkiego wprowadzenia w podstawy tego języka, zamieszczę tutaj szereg bogato komentowanych, niewielkich programów ilustrujących poszczególne zagadnienia. Omówię również korzystanie z ważniejszych/ciekawszych bibliotek (w tym bibliotek standardowych C i C++). Na wstępie zachęcam do zapoznania się z przykładem zamieszczonym w części "wstępu do techniki" poswięconej porgramowaniu, a także przykładom wprowadzającym w podstawy C i C++.
