  3. TURKCELL GROUP REGIONAL LEADER 9 countries 65.8 millionsubscribers Leadership in the region TurkcellGroup: Subscribersin Q2.12 (million) Listedon the NYSE and the ISEsince July 2000 0.5 million net additionsin Q2.12 (*): Revenues from Fintur (operations in Kazakhstan, Azerbaijan, Georgia, Moldova) is not included undersubsidiaries. The contribution of Fintur is recorded under share of profit of associates below EBITDA line. (**) Voice revenues include outgoing, incoming, roaming and other (comprising almost 2% of Turkcell Turkey) revenues 3

  8. Basics of Coherence Oracle Coherence is the industry leading in-memory data grid solution that enables organizations to predictably scale mission-critical applications by providing fast access to frequently used data

  9. Coherence Usage in RBM Types of Usage Data Transfer Active-Passive Process of multiple applications Storage-Enrichment Assurance of dataflow

  10. Coherence Usage in RBM Data Transfer Each application has a CQC(Continuous Query Cache) Each application has an input queue(Blocking Queue) Each application redirects/deletes Cache Item

  11. Coherence Usage in RBM Data Transfer Application reads items from DB Each application adds its identity into «Application Registry» cache Application sets their «next dest» area by Round Robin(load balancing) and inserts into the cache

  12. Coherence Usage in RBM Data Transfer

  13. Coherence Usage in RBM Active-Passive Process of multiple applications

  14. Coherence Usage in RBM Storage-Enrichment Storage cache , we use, are for preventing unnecessary outer systemcalls

  15. Coherence Usage in RBM Storage-Enrichment Enrichment cache includes 35M items which are consist of outer system data(54 GB memory usage in 9 nodes over 3 machines) In order to prevent unnecessary system calls, events are enriched with outer system data

  16. Coherence Usage in RBM Assurance of Data Flow In order to prevent data loss and functually operate replays/retrys of data, events are being stored temporarily Each application is responsible to remove the item which is being processed by itself A filter operates over cache periodicly to get the items which have not been processed Result of the filter , items which have not been processed yet, are sent into the process again

  17. Conclusion RBM is a very important project for Turkcell The expectation from RBM is getting higher each day Coherence Cache has a major role in this state of RBM We used Coherence in a lot of place of the project for different purposes In order to increase performance, more usage of Coherence will be needed in the future
