The OpenMessaging project welcomes Yahoo! JAPAN and EMQ X as new members.

We are excited to announce two new members to the OpenMessaging project: Yahoo! JAPAN, one of the largest portal sites in Japan, and EMQ X, one of the most popular MQTT message middleware vendors. Yahoo! JAPAN and EMQ X join Alibaba, JD.com, China Mobile Cloud, Qing Cloud, and other community members to form a standards community with 13 corporation members.

OpenMessaging is a standards project for messaging and streaming technology. Messaging and Streaming products have been widely used in modern architecture and data processing, for decoupling, queuing, buffering, ordering, replicating, etc. But when data transfers across different messaging and streaming platforms, compatibility problems arise, which always means much additional work. The OpenMessaging community looks to eliminate these challenges through creating a global, cloud-oriented, vendor-neutral industry standard for distributed messaging.

Yahoo! JAPAN, operated by Yahoo Japan Corporation, is one of the largest portal site in Japan. Under the mission to be a “Problem-Solving Engine,” Yahoo Japan Corporation is committed in solving the problems of the people and society leveraging the power of information technologies. The company uses various messaging systems (e.g., Apache Pulsar, Apache Kafka and RabbitMQ) to create its services and is creating a centralized pub-sub messaging platform that deals with a vast number of service/application traffics.

“Yahoo Japan Corporation uses various messaging systems (e.g., Apache Pulsar, Apache Kafka and RabbitMQ) to create its services. However, differences in messaging interfaces make the whole system complicated and lead to extra costs in implementation and in studying each system. Thus, we need a standardized and unified interface that can be easily implemented and easily collaborated with other services.” said Nozomi Kurihara, the Manager of the Messaging Platform team in Yahoo Japan Corporation. “We think OpenMessaging is the key in achieving our “multi big data” system in which data can be cross-used among different services/applications we provide.”

Originated from a GitHub open source IoT project starting from 2012, EMQ X has become one of the most popular MQTT message middleware in community. EMQ X is based on the Erlang/OTP platform, which can support 10 million concurrent MQTT connections with high throughput and low latency. EMQ X now has 500k downloads, and 5000+ customer users in 50 countries and regions around the world, such as China, United States, Australia, British, and India. 

“Our customers cover different industries, such as financial, IoV, telecom, smart home. We also partnered with Fortune 500 companies, such as HPE, Ericsson, VMware, to provide professional IoT solutions to customers around the world. OpenMessaging is vendor-neutral and language-independent, provides industry guidelines for areas of finance, e-commerce, IoT and Big Data, and aimed to develop messaging and streaming applications across heterogeneous systems and platforms.” said Feng Lee, Co-founder of EMQ X. “We’re glad to join OpenMessaging.”

As an effort to standardize distributed messaging and streaming systems, OpenMessaging is committed to embracing an open, collaborative, intelligent, and cloud-native era with all its community members.

ACRN is a flexible, lightweight reference hypervisor, built with real-time and safety-criticality in mind.

This article was produced by The Linux Foundation with contributions from Eddie Dong, Principle Engineer of Intel Open Source Center.

As the Internet of Things has grown in scale, IoT developers are increasingly expected to support a range of hardware resources, operating systems, and software tools/applications. This is a challenge given many connected devices are size-constrained. Virtualization can help meet these broad needs, but existing options don’t offer the right mix of size, flexibility, and functionality for IoT development.
ACRN

ACRN is different by design. Launched at Embedded Linux Conference 2018, ACRN is a flexible, lightweight reference hypervisor, built with real-time and safety-criticality in mind and optimized to streamline embedded development through an open source platform.

One of ACRN’s biggest advantages is its small size — roughly only 25K lines of code at launch.

“The idea for ACRN came from our work enabling virtualization technology for customers,” said Imad Sousou, Corporate Vice President and General Manager of the Open Source Technology Center at Intel, which seeded the source code to launch the project. “There’s strong workload consolidation in embedded IoT development. Using hypervisor technology, workloads with mixed-criticality can be consolidated on a single platform, lowering development and deployment costs and allowing for a more streamlined system architecture.”

And about the name: ACRN is not an acronym. Pronounced “acorn,” the name symbolizes something that starts small and grows into something big, similar to how the project hopes to grow through community participation.

There’re two key components of ACRN: the hypervisor itself and the ACRN device model. The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on bare-metal. The ACRN Device Model is a reference framework implementation for virtual device emulation that provides rich I/O virtualization support currently planned for audio, video, graphics, and USB. More mediator features are expected as the community grows.

How it works

ACRN features a Linux-based Service operating system (OS) running on the hypervisor and can simultaneously run multiple guest operating systems for workload consolidation. The ACRN hypervisor creates the first virtual environment for the Service OS and then launches Guest OSes. The Service OS runs the native device drivers to manage the hardware and provides I/O mediation to the Guest OS.ACRN

The Service OS runs with the system’s highest virtual machine priority to meet time-sensitive requirements and system quality of service (QoS). The Service OS runs Clear Linux* today, but ACRN can support other Linux* distros or proprietary RTOS as either the Service OS or Guest OS. The community is invited to help enable other Service OS options, and use the reference stack to enable Guest OSes such as other Linux* distributions, Android*, Windows* or proprietary RTOSes.

To keep the ACRN hypervisor code base as small and efficient as possible, the bulk of device model implementation resides in the Service OS to provide sharing and other capabilities. The result is a small footprint, low-latency code base optimized for resource constrained devices, built with virtualization functions specific to IoT development, such as graphics, media, audio, imaging, and other I/O mediators that require sharing of resources. In this way ACRN fills the gap between large datacenter hypervisors and hard partitioning hypervisors, and is ideal for a wide variety of IoT development.

One example is the Software Defined Cockpit (SDC) in vehicles. Using ACRN as the reference implementation, vendors can build solutions including the instrument cluster, in-vehicle infotainment (IVI) system, and one or more rear-seat entertainment (RSE) systems. The IVI and RSE systems can run as an isolated Virtual Machine (VM) for overall system safety considerations.

Software Defined Industrial Systems (SDIS) are further examples, including cyber-physical systems, IoT, cloud computing and cognitive computing. ACRN can help SDIS consolidate industrial workloads and can be orchestrated flexibly across systems. This helps provide substantial benefits to customers including lower costs, simplified security, increased reliability, and easier system management, among others.

Early endorsement of ACRN includes Intel, ADLINK Technology, Aptiv, LG Electronics, and Neusoft. Community members are invited to download the code and participate at the ACRN GitHub site. More detailed use case information and participation information can be found on the ACRN website.

Join us at Open Source Summit + Embedded Linux Conference Europe in Edinburgh, UK on October 22-24, 2018, for 100+ sessions on Linux, Cloud, Containers, AI, Community, and more.

Through a collaborative effort from enterprises and communities invested in cloud, big data, and standard APIs, I’m excited to welcome the OpenMessaging project to The Linux Foundation. The OpenMessaging community’s goal is to create a globally adopted, vendor-neutral, and open standard for distributed messaging that can be deployed in cloud, on-premise, and hybrid use cases.

Alibaba, Yahoo!, Didi, and Streamlio are the founding project contributors. The Linux Foundation has worked with the initial project community to establish a governance model and structure for the long-term benefit of the ecosystem working on a messaging API standard.

As more companies and developers move toward cloud native applications, challenges are developing at scale with messaging and streaming applications. These include interoperability issues between platforms, lack of compatibility between wire-level protocols and a lack of standard benchmarking across systems.

In particular, when data transfers across different messaging and streaming platforms, compatibility problems arise, meaning additional work and maintenance cost. Existing solutions lack standardized guidelines for load balance, fault tolerance, administration, security, and streaming features. Current systems don’t satisfy the needs of modern cloud-oriented messaging and streaming applications. This can lead to redundant work for developers and makes it difficult or impossible to meet cutting-edge business demands around IoT, edge computing, smart cities, and more.

Contributors to OpenMessaging are looking to improve distributed messaging by:

  • Creating a global, cloud-oriented, vendor-neutral industry standard for distributed messaging
  • Facilitating a standard benchmark for testing applications
  • Enabling platform independence
  • Targeting cloud data streaming and messaging requirements with scalability, flexibility, isolation, and security built in
  • Fostering a growing community of contributing developers

You can learn more about the new project and how to participate here: http://openmessaging.cloud

These are some of the organizations supporting OpenMessaging:

“We have focused on the messaging and streaming field for years, during which we explored Corba notification, JMS and other standards to try to solve our stickiest business requirements. After evaluating the available alternatives, Alibaba chose to create a new cloud-oriented messaging standard, OpenMessaging, which is a vendor-neutral and language-independent and provides industrial guidelines for areas like finance, e-commerce, IoT, and big data. Moreover, it aims to develop messaging and streaming applications across heterogeneous systems and platforms. We hope it can be open, simple, scalable, and interoperable. In addition, we want to build an ecosystem according to this standard, such as benchmark, computation, and various connectors. We would like to have new contributions and hope everyone can work together to push the OpenMessaging standard forward.” — Von Gosling, senior architect at Alibaba, co-creator of Apache RocketMQ, and original initiator of OpenMessaging

“As the sophistication and scale of applications’ messaging needs continue to grow, lack of a standard interface has created complexity and inflexibility barriers for developers and organizations. Streamlio is excited to work with other leaders to launch the OpenMessaging standards initiative in order to give customers easy access to high-performance, low-latency messaging solutions like Apache Pulsar that offer the durability, consistency, and availability that organizations require.” — Matteo Merli, software engineer at Streamlio, co-creator of Apache Pulsar, and member of Apache BookKeeper PMC

“Oath–a Verizon subsidiary of leading media and tech brands including Yahoo and AOL– supports open, collaborative initiatives and is glad to join the OpenMessaging project.” Joe Francis, director, Core Platforms

“In Didi, we have defined a private set of producer API and consumer API to hide differences among open source MQs such as Apache Kafka, Apache RocketMQ, etc. as well as to provide additional customized features. We are planning to release these to the open source community. So far, we have accumulated a lot of experience on MQs and API unification, and are willing to work in OpenMessaging to construct a common standard of APIs together with others. We sincerely believe that a unified and widely accepted API standard can benefit MQ technology and applications that rely on it.” — Neil Qi, architect at Didi

“There are many different open source messaging solutions, including Apache ActiveMQ, Apache RocketMQ, Apache Pulsar, and Apache Kafka. The lack of an industry-wide, scalable messaging standard makes evaluating a suitable solution difficult. We are excited to support the joint effort from multiple open source projects working together to define a scalable, open messaging specification. Apache BookKeeper has been successfully deployed in production at Yahoo (via Apache Pulsar) and Twitter (via Apache DistributedLog) as their durable, high-performance, low-latency storage foundation for their enterprise-grade messaging systems. We are excited to join the OpenMessaging effort to help other projects address common problems like low-latency durability, consistency and availability in messaging solutions.” — Sijie Guo, co-founder of Streamlio, PMC chair of Apache BookKeeper, and co-creator of Apache DistributedLog

One of my primary goals at The Linux Foundation is to foster innovation across the entire open source networking ecosystem. This involves coordinating across multiple open source projects and initiatives and identifying key areas for collaboration to create an open source networking stack.

We are working across the entire ecosystem with industry-leading partners — from developers to service providers to vendors — to unify various open source components and create solutions that will accelerate network transformation. As part of this journey, I am pleased to introduce Open Source Networking Days (OSN Days), a series of free events that are hosted and organized by local user groups and The Linux Foundation members, with support from our projects, including DPDK, FD.io, ONAP, OpenDaylight, OPNFV, PNDA, and others.

OSN Days are a fantastic opportunity for network developers and users to learn how ONAP, OPNFV, OpenDaylight  and other open source initiatives are changing NFV/SDN orchestration and networking solutions. Stops on the tour include: Paris, Milan, Stockholm, London, Tel Aviv, and Japan. Register today for an upcoming OSN Day in your region.

The day-long events will start with a plenary session where attendees will hear from site hosts and The Linux Foundation speakers on the state of the industry and the collaboration and touch points between projects that make up the open source networking stack. Presenters will also explore how business opportunities like 5G and IoT are enabled by network transformation.  In the afternoon, events may feature technical sessions, tutorials, demonstrations, and workshops that empower attendees to participate, contribute, and deepen their knowledge of open source networking.

Our first OSN Day kicks off October 9 in Paris, followed by stops in Milan (October 12), Stockholm (October 13), London (October 16), Tel Aviv (October 19), and Japan (October 19). Thanks to our incredible site hosts and sponsors Amdocs, ATOS, Cloudify, Ericsson, Huawei, NEC, Orange, Red Hat, SUSE, and Vodafone, along with our high-caliber roster of speakers, for helping to make these OSN Days a reality!

More details about the events, including site-specific agendas, registration info, and details on hotel and travel, can be found here: https://sites.google.com/linuxfoundation.org/osndays/home. If you have any questions, or would like to host an event yourself in the future, please email OSNDays@linuxfoundation.org.

Open source is now mainstream. More and more developers, organizations, and enterprises are are understanding the benefits of an open source strategy and getting involved. In fact, The Linux Foundation is on track to reach 1,000 participating organizations in 2017 and aims to bring even more voices into open source technology projects ranging from embedded and automotive to blockchain and cloud.

Just this week, AT&T joined The Linux Foundation as a Platinum Member, and 16 other organizations joined as Silver Members. Together, these organizations combine to help support development of the greatest shared technology resources in history, while accelerating innovation across industry verticals.

AT&T’s commitment to open source follows news of the company’s contribution of several million lines of ECOMP code to The Linux Foundation. Additionally, Chris Rice, senior vice president of AT&T Labs, joined The Linux Foundation Board of Directors and was also recently selected as the ONAP chairman.

The Linux Foundation is excited about the recent merger of open source ECOMP and OPEN-O, which formed the Open Network Automation Platform (ONAP) project initiated by China Mobile. The newly formed ONAP will allow end users to automate, design, orchestrate, and manage services and virtual functions. Through this amalgamation of projects, ONAP creates a harmonized framework for real-time, policy-driven software automation of virtual network functions and is poised to deliver a unified architecture and implementation faster than any one project could on its own.

AT&T, along with other members, service providers, developers, and industry leaders, will be at Open Networking Summit next week, April 3-6, in Santa Clara, CA to discuss networking topics, share insights, and shape the future of the industry. The event will feature an enterprise track, more than 75 sessions, and keynotes from networking visionaries.

The new Silver members include: Amihan Global Strategies, BayLibre, Bell Canada, China Merchants Bank, Comcast, Ericsson, Innovium, Kinvolk, Kontena, Kubique, Metaswitch Networks, Monax, Pinterest, SAP SE, SELTECH, and Tech Mahindra.

In addition to joining the Foundation, many of these new members have joined Linux Foundation projects across a wide range of technologies, such as Automotive Grade Linux, Cloud Native Computing Foundation, Hyperledger, Open Container Initiative, Open Mainframe Project, Open Network Automation Platform (ONAP), OpenSwitch, and Yocto Project.

The Linux Foundation is also excited about a new initiative in the IoT space. If you’re working in the edge networking/IoT space and want to learn more, please contact Mike Woster.

IoT is largely transitioning from hype to implementation with the growth of smart and connected devices spanning across all industries including building automation, energy, healthcare and manufacturing. The automotive industry has given some of the most tangible examples of both the promise and risk of IoT, with Tesla’s ability to deploy over-the-air software updates a prime example of forward-thinking efficiency. On the other side, the Jeep Cherokee hack in July 2015 displayed the urgent need for security to be a top priority for embedded devices as several security lapses made it vulnerable and gave hackers the ability to remotely control the vehicle. One of the security lapses included the firmware update of the head unit (V850) not having the proper authenticity checks.

The growing number of embedded Linux devices coming online can impact the life and health of people, communities, and nations. And given the upward trajectory of security breaches coinciding with the increasing number of connected devices, the team at Mender decided to address this growing need.

Mender is an open source project to make it easier to deploy over-the-air (OTA) software updates for connected Linux devices (Internet of Things). Mender is end-to-end, providing both the backend management server for campaign management for controlled rollouts of software updates and the client on the device that checks for available updates. Both backend and client are licensed under the Apache License, Version 2.0.

Mender recently became a corporate member of the Linux Foundation. Here, we sit down with their team to learn more about their goals and open source commitment.

Linux.com: What does Mender do?

Thomas Ryd, CEO of Mender: our mission is to secure the world’s connected devices. Our team is focusing the project to be an accessible and inexpensive approach to securing their connected devices. Our goal is to build a comprehensive security solution that is not only inexpensive to use, but easy to implement and use. That will naturally drive Mender to be the de facto standard for securing connected Linux devices.

Eystein Stenberg, CTO of Mender: our first application is an over-the-air software updater for embedded Linux and our first production-ready version will focus on an atomic, dual file system approach to ensure robustness — in case of a failed update due to power failure or poor network connectivity, the device will automatically roll back to the previous working state.

Linux.com: How and why is open source important to Mender?

Ralph Nguyen, Head of Community Development: When we initially ventured into this problem, there were very little OTA solutions that were end-to-end open source. There were limits to some end-to-end vendors for their backend, while others were simply incomplete and didn’t have either a backend or client. There are many proprietary software products targeting the automotive industry, but none provided the level of openness we anticipated. And most of the embedded Linux folks we’ve spoken to implemented a homegrown updater. It was quite common that they had a strong distaste for maintaining it! This was a recurring theme that sealed our initial direction with OTA updates.

And the accessibility of our project for embedded Linux developers is important from a larger perspective: security is a major, tangible threat given recent events such as the Mirai botnet DDoS attack and developers shouldn’t be faced with vendor lock-in to address these very real challenges.

Linux.com: Why did Mender join the Linux Foundation?

Ryd: The Linux Foundation supports a diverse and inclusive ecosystem of technologies and is helping to fix the internet’s most critical security problems. We felt it was only natural to join and become a member to solidify our commitment to open source. We hope it will be an arena for learning and collaboration for the Mender project.

Linux.com: What are some of the benefits of collaborative development for such projects and how does such collaboration benefit Mender’s customers or users?

Nguyen: Our team has a background in open source, and we get that the more eyes there are, the security and quality of the code will increase accordingly. A permissive open source license such as ours encourages a thriving open source community which in turn provides a healthy peer review mechanism that closed source or other restrictive licenses simply cannot compete with. We anticipate the Mender project will improve vastly from a thriving, collaborative community which we hope to encourage and support properly.

Linux.com: What interesting or innovative trends are you witnessing and what role does Linux or open source play in them?

Stenberg: The core mechanisms required for almost any IoT deployment, for example within smart home, smart city, smart energy grids, agriculture, manufacturing, and transportation, is to collect data from sensor networks, analyze the data in the cloud and then manage systems based upon it.

A simple use case from the home automation industry is to open your home from your smartphone. It typically requires the states of the locks in your home to be published to the cloud (data collection), the cloud to visualize the overall state to your smartphone, open or locked (analyze) and give you the ability to change the overall state (manage).

The capabilities of the IoT devices vary, it can be a very heterogeneous environment, but they can generally be split into 1) low-energy sensors that run a small RTOS (Real Time Operating System) firmware of tens or hundreds of kilobytes and 2) local gateways that aggregate, control and monitor these sensors, as well as provide internet connectivity.

Linux plays a large and increasingly important role in the more intelligent IoT devices, such as these local gateways. Historically, the majority of device vendors developed their own proprietary operating systems for these devices, but this is changing due to the increasing software complexity. For example, developing a bluetooth or TCP/IP stack, web server or cryptographic toolkit does not add any differentiation to a product, while it does add significant cost. This is an area where the promise of open source collaboration is working very well, as even competitors are coming together to design and implement the best solution for the community.

Cost and scale are two important keywords for the IoT. Embedded development has historically required a lot of customizations and consulting, but in the future we will see off-the-shelf products with very large deployments, both in terms of hardware and software.

Linux.com: Anything else important or upcoming that you’d like to share?

Ryd: We have been working on Mender for two years and it has been a market-driven approach. Our team has engaged with over a hundred embedded Linux developers in various capacities, including many many user tests to ensure we were building a comprehensive solution to address software updates for IoT. What has become clear is the state of the union is downright scary. There have and will forever be bugs in software. Shipping connected products that can impact people’s lives and health not having a secure and reliable way to update software should soon be a thing of the past.

1. Home Assistant: The Python Approach to Home Automation

Several home automation platforms support Python as an extension, but if you’re a real Python fiend, you’ll probably want Home Assistant, which places the programming language front and center. Paulus Schoutsen created Home Assistant in 2013 “as a simple script to turn on the lights when the sun was setting,” as he told attendees of his recent Embedded Linux Conference and OpenIoT Summit presentation, “Automating your Home with Home Assistant: Python’s Answer to the Internet of Things.”

Schoutsen, who works as a senior software engineer for AppFolio in San Diego, has attracted 20 active contributors to the project. Home Assistant is now fairly mature, with updates every two weeks and support for more than 240 different smart devices and services. The open source (MIT license) software runs on anything that can run Python 3 — from desktop PCs to a Raspberry Pi, and counts thousands of users around the world.

2. Linus Torvalds Talks IoT, Smart Devices, Security Concerns, and More

Linus Torvalds, the creator and lead overseer of the Linux kernel, and “the reason we are all here,” in the words of his interviewer, Intel Chief Linux and Open Source Technologist Dirk Hohndel, was upbeat about the state of Linux in embedded and Internet of Things applications. Torvalds’ very presence signaled that embedded Linux, which has often been overshadowed by Linux desktop, server, and cloud technologies, has come of age.

“Maybe you won’t see Linux at the IoT leaf nodes, but anytime you have a hub, you will need it,” Torvalds told Hohndel. “You need smart devices especially if you have 23 [IoT standards]. If you have all these stupid devices that don’t necessarily run Linux, and they all talk with slightly different standards, you will need a lot of smart devices. We will never have one completely open standard, one ring to rule them all, but you will have three of four major protocols, and then all these smart hubs that translate.”

3. Taming the Chaos of Modern Caches

It turns out that software — and computer education curricula — have not always kept up with new developments in hardware, ARM Ltd. kernel developer Mark Rutland said in his presentation “Stale Data, or How We (Mis-)manage Modern Caches.”

“Cache behavior is surprisingly complex, and caches behave in subtly different ways across SoCs,” Rutland told the ELC audience. “It’s very easy to misunderstand the rules of how caches work and be lulled into a false sense of security.”

4. IoTivity 2.0: What’s in Store?

Speaking shortly after the release of Open Connectivity Foundation (OCF)’s IoTivity 1.1, Vijay Kesavan, a Senior Member of Technical Staff in the Communication and Devices Group at Intel Corp, told the ELC audience about plans to support new platforms and IoT ecosystems in v2.0. He also explained how the OCF is exploring usage profiles beyond home automation in domains like automotive and industrial.

5. A Linux Kernel Wizard’s Adventures in Embedded Hardware

Sometimes the best tutorials come not from experts, but from proficient newcomers who are up to date on the latest entry-level technologies and can remember what it’s like to be a newbie. It also helps if, like Grant Likely, the teacher is a major figure in embedded Linux who understands how hardware is ignited by software.

At the Embedded Linux Conference, Likely — who is a Linux kernel engineer and maintainer of the Linux Device Tree subsystem used by many embedded systems — described his embedded hardware journey in a presentation called “Hardware Design for Linux Engineers” — or as he put it, “explaining stuff I only learned six months ago.”
