The document covers the basics of cloud technology for embedded designers, detailing the advantages and disadvantages of various networking options for the Internet of Things (IoT). It discusses how the cloud can enhance user experience, reduce costs, and provide new services through functionalities like remote diagnostics and asset management. Additionally, it highlights the evolution of product requirements, the challenges posed by the lack of standardization, and the importance of aligning design goals with cloud capabilities.

1. CLOUD 101 FOR EMBEDDED DESIGNERS

2. Abstract
• Attendees will learn about the PROs and CONs
of different connection options for the
Internet of Things.
• The class will cover Ethernet, WiFi, cellular,
and mesh networking options and also talk
about tradeoffs for each (security, reliability,
performance, and cost).

3. What is the cloud?
• Definition: Scalable servers connected to the Internet
that provide certain functionality.
• Some applications in “The Cloud”:
– Salesforce -> Sales, CRM
– Amazon Cloud Drive, Box.net -> Data storage
– Google Apps -> Office productivity
– Mint, Quickbooks -> Financial
• Today, we are talking about “The Cloud” as it pertains to
embedded systems.

4. Market evolution
For anyone who has designed or spec’d a product in the past 12 years, there
has been a race to add the next thing to meet customer needs, improve the
product, drive down costs, keep up with the competition:

7. What can the cloud do?
• Add value by enhancing user experience
• Add revenue by offering new services
• Reduce expenses by improving business processes
and managing firmware updates, support, and data
collection from a central vantage point
• Understand users by analyzing use patterns
• Make better decisions by integrating with existing
business systems

8. Converging perspectives

9. We’ve got problems
• New product categories are emerging
• Vocabulary is not standardized
• Consensus standards are immature
• Differing interpretations of what IoT/M2M is

19. Parting thoughts
• Understand your design goals
– Flexibility vs. cost
– Performance vs. power
• Understand your options
– Modules, aggregators, gateways, cellular networks,
cloud platforms, mobile frameworks
• Focus on your core competencies; buy the rest
• Prepare for the next frontier: federation of
services (CRM, ERP, social networks)

20. We’ve got opportunities
• Bring simplicity where there is complexity
• Design solutions where there are none
• Set lasting consumer precedents
• Provide access to information that drives business decisions
and reduces risk
• Pioneer new territory
