EdgeX ARM64 Support

By Blog, EdgeX Foundry

Written by Gorka Garcia and Federico Claramonte from Cavium 

Cavium, a provider of highly integrated semiconductor processors that enable intelligent networking, communications, storage, video and security applications, recently joined EdgeX Foundry and is already an active contributor.

We are using our OCTEON TX family of Multi-Core 64-bit ARM Embedded Processors to target the intelligent IoT Edge Gateway market.  We believe in open source technologies for this market and value EdgeX Foundry for its scalability and flexibility.

Over the past few months, Cavium has helped create a strong ARM64-based version of the EdgeX platform that is on par with the versions for other CPU platforms.  Our particular focus was on ensuring efficient execution of the platform on OCTEON TX processors using a intelligent edge gateway reference design.

As we started the port, the first issue we met was the lack of ARM64 support in EdgeX docker containers. As a first pass, we ran EdgeX without using containers and just calling the micro-services directly. This worked at first try, as the EdgeX software is written in java and it did not use any native libraries. Then, we created a new set of ARM64 containers that can be deployed to ARM64 in the same way as x86. While doing this, we simplified the docker container process creation by implementing some scripts that will handle that task. When running all the containers in our lower memory ARM64 boards, we noticed a peak of memory usage at startup. After some investigation, we managed to reduce these memory peaks by simplifying the startup process, managing to also improve the startup time of EdgeX. These are changes that benefit all supported platforms, not just ARM64. Right now we are involved in the porting of some micro-services from java to Go Lang, which will help reduce memory footprint even further as well as improve the overall performance.

All our work has been contributed to the EdgeX Foundry community as we believe interoperability is key for IoT solutions success and are committed to help grow the EdgeX ecosystem. Throughout this whole process, we had support from the EdgeX community, answering our questions and giving feedback on our work. Cavium will continue supporting the EdgeX Foundry project to make sure it runs well in our ARM64 processors as well as doing generic optimizations of the services that could benefit the whole community.

TelecomTV:The Linux Foundation’s EdgeX Foundry IoT framework announced

By EdgeX Foundry, In the News

Nobody said IoT was going to be easy. Well they did actually, but we all knew that was being economical with the truth.  And now, according to The Linux Foundation, “the complexity of the current IoT landscape and the wide variety of components available, are creating paralysis among businesses looking to deploy [Industrial] IoT solutions.”

It then cheerfully announces that it’s releasing more components of its own – not to add to the cacophony but to provide an interoperability framework so that solutions can be plugged and played with, the best can prove their worth and be widely adopted, and the also-rans  can be edged out.

The Future of EdgeX is Go Go Go with Go Lang

By Blog, EdgeX Foundry

Written by Jim White, EdgeX Foundry TSC Member and  Chair of Core Services Working Group

To begin this post, I need to give you a little history.  When my team and I started on Project Fuse (which became EdgeX Foundry) at Dell some two years ago, we knew the micro service architecture was going to be the mechanism to deliver the edge/IoT platform to satisfy our ideal platform.  What we weren’t sure about was the programming language to use to get started in writing our microservices.  As we looked around at options we knew we needed a very powerful and flexible programming platform that would provide all sorts of tools and connectors to the various protocols of the IoT world.  Many of the newly emerging languages, like Go Lang, just didn’t ring the bell on the availability of tools and connectors at the time.  So, we went with Java as our primarily programming language as it was well known to us, provided all the libraries and connectors we could want, and it seemed to be in line with the other products we wanted to integrate with at the time.  We also knew that the microservice architecture would allow us to add or replace a microservice in the future using a different language if we needed.  To be honest, our project was a proof of concept system so the choice in language was less relevant then than today.

As we fast forward to EdgeX’s introduction this spring, it was clear from the community that while the concept architecture we built with Fuse was on the mark, we needed to eventually improve EdgeX’s performance, footprint, and scalability – especially to meet the mission critical edge use cases we would encounter.  Languages like Go Lang have come a long way, and many of our community members were already seeing incredible improvements using Go Lang in their IoT solutions.  Indeed, even at Dell, as we were getting ready to introduce EdgeX into the open source community, we had started to experiment with Go Lang (and other languages) and had even developed some replacement micro services to demonstrate the potential performance/footprint improvements while also trying to understand the challenges.

Today, I am pleased to announce that the EdgeX community has formalized plans to develop preview EdgeX microservices in Go Lang and make them available by Jan 31, 2018.  This will be a preview of the California release of EdgeX scheduled for the spring of 2018.  We will release these Go Lang services but will not be making any other changes to the system’s functionality or API set – in other words, these Go-based microservices should be drop in replacements to their Java counterparts.  And for the foreseeable future, we plan to support both the Java and Go Lang versions as we know the Java and Go Lang communities are vibrant and may want/need these alternatives in their particular IoT solutions.

Specifically, we plan on releasing the following microservices in early 2018 as part of this preview release:

  • Core Data, Core Metadata, Core Command microservices
  • Export Client microservice
  • Initial elements/libraries to a Go Lang Device Service SDK

Additional microservices and facilities may be added to this list depending on work accomplished between now and then.  Much of this work is actually already underway – in parallel to our efforts as a community to get the Barcelona release out this fall.  We hope to have some preliminary performance and footprint numbers (in comparison to the existing Java microservices) so people will have an understanding of the impact of this work by the time we showcase the Barcelona release in the fall.

We are hopeful this work will also help demonstrate the community’s commitment to drive down the size and speed of EdgeX to meet today’s edge platforms.  Much work remains, but this will help provide proof positive that the platform is heading in the right direction and will help galvanize the community around our desire to solve real world IoT/edge use cases.

By the way, don’t let this work suggest that EdgeX is going to use Go as the only development language going forward.  One of the core tenets of EdgeX is to be polyglot and use the tools of choice for each microservice to best meet the use case need.  As an example, others in our community are already on record (IoTech, Inc. for example) in their desire and focus to eventually develop a C based device service and device service SDK.  C/C++ will probably make a lot of sense when trying to operate a device service on very constrained device hardware and offers extreme performance improvements.  Go simply offers a popular alternative to Java that is seeing wide use in the IoT community and helps us get the collective footprint and performance of EdgeX down fairly quickly.

So, do you like to work in Go?  Lend us a hand!  Come join us in the EdgeX community as we try to build the best open source IoT/edge platform on the planet!

Getting Data from EdgeX to Google Cloud IoT Core

By Blog, EdgeX Foundry

Written by Jim White, EdgeX Foundry TSC Member and  Chair of Core Services Working Group

The EdgeX Foundry community continues to grow as does the EdgeX functionality thanks to contributions from around the world.  In this post, I’d like to highlight an exciting addition to the EdgeX “northbound” interface.  That is, a new capability built into the EdgeX export services that allows EdgeX data to be sent to Google Cloud IoT Core.

What is Google IoT Core?  It’s a Google public beta cloud service (what Google calls a fully managed service) that allows you to easily and securely connect, manage, and ingest data from millions of globally dispersed devices.  See for more details.

For those unfamiliar with the EdgeX architecture, the services responsible for organizing, formatting, transforming, etc. the sensor data collected by EdgeX and sending it to enterprise or cloud based systems are the export services.  In the EdgeX and IoT communities, we often call theses the “northbound” services or interfaces as they are typically depicted on the top end of any diagram that depicts an edge platform.  “Southside” services or interfaces are those that communicate with sensors, devices or other systems even closer to the “things” edge and are usually depicted at the bottom of any diagram.

Bernard Van Haecke from Schlumberger, Menlo Park, CA office dug into EdgeX when it was released and recently had his connector contribution approved and posted as part of the Export services.  What his addition does is allow the export services to pipe data to Google IoT Core.

EdgeX export services already allowed for sending data to any MQTT topic or HTTP REST endpoint generically and to Azure IoT Hub specifically.  We believe going forward, there will be lots of these connectors – some public and some private (perhaps you will need one to your own closed enterprise system).  But Bernard will always have the distinction of being our first new connector on the northside.  Thanks Bernard!

SDxCentral: EdgeX’s Barcelona Release Sets Path for Open Source IoT

By EdgeX Foundry, In the News

EdgeX Foundry, the Linux Foundation’s open source industrial Internet of Things (IoT) group, is making its first major code release, dubbed Barcelona, available later this month. The new release promises to help take the complexity out of IoT by supporting certain key APIs as well as industrial protocols like Bluetooth Low Energy, MQTT (a low-energy machine-to-machine protocol), and simple network management protocol (SNPP).

According to Philip DesAutels, senior director of IoT at the Linux Foundation, the Barcelona release will be especially helpful to small- and medium-sized companies that don’t have a lot of IT resources to devote to integrating different tools and components. “Today if you want to do what EdgeX offers, you have to have a room full of smart developers that can pick components from here and services from there and then integrate those and make them work together,” DesAutels said. “It’s very complicated.”
