More Challenges
► More subscribers (data, image, video)► Network congestion– Spectrum + cell towers + antennas
► Bandwidth caps► High Latency– Phone Tower Mobile Infrastructure Internet
Mobile developers must solve these problems to delight the end user!
Supporting Millions of Connected Devices
Database(s) that nobody touches
Thousands of servers on commodity hardware
Replicated, horizontally-scaled NoSQL databases; Data sharding using small tables for fast access
Load-balancing at every tier
Terabytes in an in-RAM, distributed cache
MapReduce for parallel analysis of “big data”
How will You Scale?Windows Azure
SQL Azure is never touched by devicesWorker Roles replicate outbound data from SQL Azure to NoSQL Table or Blob StorageWorker Roles move inbound data from Azure queues to SQL Azure
Scale-out Windows Azure instances as needed
Wireless efficiency is realized via Web Roles that use REST + JSON WCF Services
Distributed caching via AppFabric Caching
Devices cache data and work offline
