The Current State of WirelessWhere’s the bandwidth?

AT&T: “We will deliver as much data over our network in the first 5 weeks of 2015 as we did all year in 2010”

Congestion factorsMore subscribers with smartphones (data | photos | videos)Spectrum + cell towers + antennas + home usersMobile operator bandwidth capsLatency cell tower backhaul network internet final destination back to the device

Mobile developers must acknowledge and deal with these issues to ensure a delightful user experience

Supporting Millions of Connected DevicesHow do they scale?

Database(s) that nobody touches

Thousands of web servers on commodity hardware

Replicated, horizontally-scaled NoSQL databases at the edge; Data sharding using small tables for fast access

Load-balancing at every tier

Hundreds of terabytes of data in an in-RAM, distributed cache

Compiling slow, web server scripting code into native

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 Azure Table 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 of REST + JSON WCF Services

Distributed caching is handled by AppFabric Caching

Devices cache data and work offline

Puget Sound Executive Submarine ServiceTravel Scenario

Residents of Bainbridge Island have long employed a variety of methods of getting to work in Seattle ranging from ferries to sea planes. A new way of traversing the Sound has arrived… it’s underwater.

Two submarines carry passengers between Seattle and Bainbridge Island every day. Each luxury submarine carries eight passengers with all first-class seating plus free Wi-Fi and coffee.

Passengers arrive at their destination quickly due to a submerged transit time of just 15 minutes plus limousines waiting at the dock to whisk them to their office.
