Getting a Deeper Edge on the Edge

By Jason Shepherd |

Attached far below is the full copy of a blog that dives deeper into key considerations when developing solutions at the IoT edge. I walk through in detail how both hardware and software inherently get more customized the closer you get to the Device Edge (see the chart below for a quick reference of the trends) and highlights key architectural and design considerations to address the related challenges. It will be running on IoT Agenda in four parts throughout August.

When reading my thoughts on hardware considerations, keep in mind that at Dell when we say that our IoT edge gateways support fan-less operation up to 70 degrees Celsius (158 degrees Fahrenheit) this is with every component that can produce heat (e.g. CPU, memory, disk, networking) running at full throttle (which is unlikely to ever happen) and allowing minimal to no thermal throttling of the CPU. Very few products in the field are tested this way, however we think it’s important to test with ample margin because these products run in business-critical settings. In terms of the comments on the importance of long-term support for edge hardware out in the field, we offer five years beyond the ship date. This applies to both the hardware and factory OS options.

From the software standpoint, when I talk about the importance of consistent device management and security our lead offer is Pulse IoT Center from VMware. Pulse is all about providing a consistent experience for onboarding, monitoring, managing and securing IoT edge devices at scale, regardless of hardware and applications you use today and in the future.

As VMware ties Pulse to the EdgeX Foundry framework with the open IoT edge stack effort it will provide developers with a consistent, supported baseline that they can get going quickly with while also maintaining complete control over their data destiny due to the open EdgeX APIs.  This award-winning stack will also enable developers to build faster by taking advantage of commercial plug-in value-add from both Dell Technologies and the broader EdgeX ecosystem.  As outlined in this and other blogs, in order to scale to the real potential over time it’s important to have a multi-cloud strategy that starts with an open edge, avoiding lock in to any particular protocol, hardware, OS or application stack.
