2 The Internet of Things Today Enormous potential Tens of billions of new devices but market growing slower than expected Embedded, but different IoT devices are often embedded but can have different requirements, constraints and goals compared to conventional embedded systems Often very strict energy or resource constraints Complexity rapidly increasing Security, manageability, updates often underestimated More sophisticated hardware requires more software and vice versa!

Slide 3

3 Embedded development is a specialized skill The tens of millions of non-embedded developers struggle with the low-level environment, lack of libraries and strict resource constraints Conversely, embedded developers struggle with internet protocols, servers, security, networking, etc Even with good embedded developers, embedded software is expensive, slow to market, and getting worse! Power management is important, but difficult Allowing the programmer to manually manage power requires they deeply understand the hardware Hardware often consumes energy in non-obvious ways Most software is not re-used Less than 25% of embedded projects use third-party software components [Source: UBM Embedded Market Study 2013] Software re-use lowers costs, time-to-market, and fosters protocol interoperability and security Connectivity introduces many new security concerns Previously isolated devices now at risk of remote attack, data leaks, and denial of service Security is also a specialized skill; non-experts often introduce subtle vulnerabilities Challenges

8 In the 90s the processor used to be the scarce resource In IoT there are different scarce resources: Energy & Productivity

Slide 9

9 ARM mbed OS Philosophy Reducing total system cost by enabling better system tradeoffs We care about this. if it results in savings here (e.g. sophisticated power management) But it can make sense to spend more here (e.g. on more memory) = + + Total CostHardware CostEnergy CostDevel. Cost (amortized, inc. deployment cost) and here. (e.g. firmware update, manageability)

Slide 10

10 Use higher-level languages that allow the developer to express their intention more succinctly and concisely, with less chance of mistakes mbed utilizes C++ for ease of development Better tools Automated testing infrastructure Improved debug and diagnostics support Increase software reuse Online community for sharing components Automate the process of incorporating software components into a project Commonly used functionality bundled into the OS Consistent power management ARM mbed OS Philosophy Increase developer productivity and reduce development costs
