Are you ready to take the next step within your IoT project? Do you want to connect your devices to the cloud? IoT field gateways are crucial if you want to roll out an efficient, secure and manageable system. In this presentation, you will find out everything about field gateways and how they cope with connectivity issues and security challenges.

1. The truth about IoT field gateways
Luis Delgado, Technical Director Codit Switzerland

2. Let’s talk about one thing today…

3. Neglecting your current installed-base means
your project will have a time-to-value of years
The retro-fitting problem

4. Where do field gateways fit in your solution?

5. Why is a field gateway important?
• 85% of devices are not Internet-ready
• Development effort in time and money (~ 9months+)
• 60% cloud cost reduction with edge processing
• Network optimization (batching, compression, message composition, queuing,
throttling)
• Consistent implementation of infrastructure capabilities (security, credentials
management)

6. Speed your time and money wisely
Don’t spend effort developing these:
• Message handling implementation
• Transport protocol implementation
• Credential management
• Health reporting and diagnostics
• Message persistence
Generic infrastructure
Spend effort developing these:
• Edge analytics
• Own protocol implementations
• Business logic modules
Value generators

7. What should a field gateway offer you?
• Combination field + cloud gateway (API-based)
• Extensible
• Cross-platform & hardware compatibility
• Modular architecture
• Cloud-to-Device management interfaces

8. Example: Azure IoT Gateway SDK
• Open source
(https://github.com/Azure/azure-iot-gateway-sdk/)
• Cross platform: Windows or Linux
• Standards based (written in ANSI C C99)
• Easy to customize

11. Conclusion

12. Key takeaways of today
• Don’t neglect your current installed base
• Field gateways are great solutions to retro-fitting problems
• Look for modular gateways that allow for extensibility (don’t focus only on
protocol compatibility, think about the future: i.e edge analytics)
• Look for gateways that provide robust infrastructure features (centralized
mgmt., data loss prevention, self-updating and software distribution, etc)
• Invest your time in tasks that generate business value (ex: edge analytics) and
let a robust gateway handle the generic “plumbing” tasks
