New repos for geo2tag codebase

We completed splitting code base of Geo2tag LBS Platform for small orthogonal repositories. New organization on github.com (https://github.com/geo2tag) is containing all of them. Everyone who desires to participate in development can request access on github.

This is current repos description

• core -- Core platform. Service which implements REST API. Now it contains database also; in the future we are planning to stay only test database here and put geotag data into separated repos.
• libgeo2tag -- Client library on C++
• jgeo -- Client library on java
• webside -- Web client (DEMO)
• geocube -- Android spacial browser
• repo -- Tools for supporting debain repository
• automation -- Automation tools

Also we will add clients (like Doctor search, tracker and so on in separated repos).

Moving sources to new place

We started to splitting source tree to several separated repos. We realized that working with one big source tree which contains all parts of the project like core service, libraries, clients, webside and so on is inconvenient. We created new source entry point https://github.com/organizations/geo2tag will be available soon. At least we will have next packages:

• core
• client library for c++
• client library for java (J2ME)
• webside

Performance analysis for LBS Geo2tag 0.19

Article about Geo2tag platform performance for version 0.19 is published (in Russian). This article describes performance optimisation for the Geo2Tag LBS-platform. Math model for client interaction with LBS-platform was created using Markov chain formalisation. Determined the most frequently used requests by set of numerical experiments. LBS-platform requests processing was profiled, bottlenecks found. Performance of request processing was optimised by changing DB structure and platform-DB synchronisation mechanism. Comparison of LBS-platform performance performed, found that performance of optimised system is better.

Methods for load balancing in LBS-platform and PostgreSQL were investigated. Math model, that describes how performance of horizontally scaled LBS-platform depends on number of nodes, performance of one node, intensity of incoming requests and load balancer performance was created. Correctness of created model was proved using set of numerical experiments.
