IoT: From Gateway to Cloud

Starting Up, Scaling Up

In this follow on to our March “IoT: From Device to Gateway” Special Feature, here we look at technologies and solutions for the gateway-to-cloud side of IoT. These solutions ease the way toward getting a cloud-connected system up and running.

By Jeff Child, Editor-in-Chief

After exploring the edge device side of the Internet-of-Things (IoT) last month, now we’ll look at cloud side the equation. Even though the idea of Internet-linked embedded devices has been around for decades, multiple converging technology trends have brought us to the IoT phenomenon of today. The proliferation of low cost wireless technology has coincided with significant decrease in the costs of computing, data storage and sensor components. Meanwhile, that same computing and storage are now widely available as cloud-based platforms that can scale linearly.

Much attention has been focused on the size of the growing IoT market in terms of revenue and number of devices. But another interesting metric is the number of IoT developers working on IoT-based systems. According to analysts, that number will approach 10 million within the next few years and a lot of that growth will be among smaller firms starting from the ground up or adding IoT to their infrastructure for the first time. For those smaller organizations the process of getting started with cloud-connected infrastructure can be a hurdle. And even after that step, there’s the issue of scaling up as the need arises to expand their IoT implementation.

Feeding both those needs, a number of companies ranging from IoT specialists to embedded software vendors to microcontroller vendors have over the past six months, rolled out a variety of solutions to help developers get started with their cloud-connected IoT system and scale that system to larger numbers of IoT edge nodes and increased cloud-based service functionality.

IoT for the Masses

With both those trends in mind, Atmosphere IoT positions itself as focused on the mass market of IoT developers. Formerly part of Anaren, Atmosphere IoT Corp. was previously Anaren’s IoT Group before Anaren divested that division in January into the newly formed Atmosphere IoT Corp. For its Atmosphere IDE product, the company provides an interesting business model. Atmosphere IDE is available for free—anyone can log on and use it. Once you get over 5 connected things and want to have Atmosphere IoT store more data and manage more things, you start paying incrementally. The idea is to make it easy for developers to generate code and get prototype systems and a limited pilot program up and running. When users are ready to scale up or when they find commercial success, they can scale linearly because all of Atmosphere’s software is built on the Amazon Web Services (AWS) cloud.

Using the IDE, developers can create either Wi-Fi or Bluetooth Smart projects and choose between supported platforms including Anaren hardware and the Intel Curie module. On the cloud development side, the Atmosphere IDE provides easy cloud connectivity access, connecting IoT devices to the cloud application to take advantage of data hosting, analysis, reporting, real-time monitoring and much more.

Industry 4.0 Solution

For its Industry 4.0 IoT solution, Mentor in February introduced its Mentor Embedded IoT Framework (MEIF). MEIF is a comprehensive, cloud vendor-agnostic embedded software framework designed to help developers create, secure and manage “cloud-ready” smart devices for Industry 4.0 applications. MEIF features well-defined interfaces engineered to complement and extend cloud vendor embedded software development kit (SDK) APIs. …

NXP IoT Platform Links ARM/Linux Layerscape SoCs to Cloud

By Eric Brown

NXP’s “EdgeScale” suite of secure edge computing device management tools help deploy and manage Linux devices running on LSx QorIQ Layerscape SoCs, and connects them to cloud services.

NXP has added an EdgeScale suite of secure edge computing tools and services to its Linux-based Layerscape SDK for six of its networking oriented LSx QorIQ Layerscape SoCs. These include the quad-core, 1.6 GHz Cortex-A53 QorIQ LS1043A, which last year received Ubuntu Core support, as well as the octa-core, Cortex-A72 LS2088a (see farther below).

The cloud-based IoT suite is designed to remotely deploy, manage, and update edge computing devices built on Layerscape SoCs. EdgeScale bridges edge nodes, sensors, and other IoT devices to cloud frameworks, automating the provisioning of software and updates to remote embedded equipment. EdgeScale can be used to deploy container applications and firmware updates, as well as build containers and generate firmware.

The technology leverages the NXP Trust Architecture already built into Layerscape SoCs, which offers Hardware Root of Trust features. These include secure boot, secure key storage, manufacturing protection, hardware resource isolation, and runtime tamper detection.

The EdgeScale suite provides three levels of management: a “point-and-click” dashboard, a Command-Line-Interface (CLI), and the RESTful API, which enables “integration with any cloud computing framework,” as well as greater UI customization. The platform supports Ubuntu, Yocto, OpenWrt, or “any custom Linux distribution.”

EdgeScale supports cloud frameworks including Amazon’s AWS Greengrass, Alibaba’s Aliyun, Google Cloud, and Microsoft’s Azure IoT Edge. The latter was part of a separate announcement released in conjunction with the EdgeScale release that said that all Layerscape SoCs were being enabled with “secure execution for Azure IoT Edge computing running networking, data analytics, and compute-intensive machine learning applications.”

A year ago, NXP announced a Modular IoT Framework, which was described as a set of pre-integrated NXP hardware and software for IoT, letting customers mix and match technologies with greater assurance of interoperability. When asked how this was related to EdgeScale, Sam Fuller, head of system solutions for NXP’s digital networking group, replied: “EdgeScale is designed to manage higher level software that could have a role of processing the data and managing the communication to/from devices built from the Modular IoT Framework.”

The EdgeScale suite supports the following QorIQ Layerscape processors:

  • LS102A — 80 0MHz single-core, Cortex-A53 with 1 W power consumption found on F&S’ efus A53LS module
  • LS1028A — dual-core ARMv8 with Time-Sensitive Networking (TSN)
  • LS1043A — 1.6 GHz quad-core, Cortex-A53 with 1 0GbE support, found on the QorIQ LS1043A 10G Residential Gateway Reference Design and the X-ES XPedite6401 XMC/PrPMC mezzanine module
  • LS1046A — quad-core, Cortex-A72 with dual 10 GbE support (also available in dual-core LS1026A model)
  • LS1088a — 1.5 GHz octa-core, Cortex-A53 with dual 10 GbE support, which is also supported on the XPedite6401
  • LS2088a — 2.0 GHz octa-core, Cortex-A72 with 128-bit NEON-based SIMD engine for each core, plus a 10GbE XAUI Fat Pipe interface or 4x 10GBASE-KR — found on X-ES XPedite6370 SBC.
