  • How to run Telco Real-time Applications on AWS
    Klaus Schuch
    Nokia Siemens Networks
    Product Management – Charging and Billing
    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
