      AWS Tech Summit Berlin – 16th May 2011
    • Nokia Siemens Networks
      • Joint Venture of Nokia and Siemens
      • Started operations on April 2007
      • €13 bn net sales in 2010
      • 65,000 employees
      • 75 of top 100 operators worldwide
      • 150 countries
      • 3 billion mobile subscribers served
      Headquarter in Espoo, Finland
      I’m here !
      Location in Berlin
    • Are our applications ready for the cloud ?
      Is the cloud ready for telco-grade applications ?
      Just two Questions …
    • This is a Telco Network
    • Challenges of Telco Real-time Applications
      • Low latency
      • Response time < 100 ms
      • … for 95% of the requests
      • High availability – 99,999%
      • Less than 5 min service downtime per year
      • …planned and unplanned
    • What is a Real-time Charging Server ?
      charge@once unified
      • Charges calls, sessions and events in real-time
      • Interacts with core network and applications
      • Real-time: no money – no service
      • Typically used for prepaid scenarios – and more and more for postpaid
      • High throughput
      • up to 20.000 database transactions/sec
      • Stores a lot of money
      • 10 € per user
      • 20 Mio user  200 Mio €

    • Results
      • Setup was surprisingly easy – 1stresults with small team within weeks
      • Charging in the cloud is feasible:
      • Latency is not an issue – within the cloud
      • Performance is as expected from the given EC2 Compute Units
      • Security concepts in AWS are pretty sophisticated
      Challenges and To-Dos
      • Our database is not cloud-ready and has to be replaced
      • Needed: In-memory database with scale-out approach
      • Elasticity has to be implemented in our application
      • High availability concepts need to make assumptions on underlying infrastructure
    • Other Cloud Activities of Nokia Siemens Networks
      • Field Service Management
      • Enable cost based service planning
      • Will be offered as SaaS
      • Customer Experience Management
      • Raising customer satisfaction
      • Will be offered as SaaS
      • SMS-Center, MMS-Center
      • Mediation, Customer Care
      • Telco2Web
