“Industry 4.0” is Driving Event-Driven Architecture to the Forefront of Modernization in Europe

The term “industry 4.0” originates from a German government initiative focused integrating the manufacturing industry with internet technologies.

The initiative aims to accelerate the integration of next-generation technologies like big data, cloud, high-performance computing and the Internet of Things with advancements in areas like artificial intelligence, autonomous systems, and 3D printing. It aims to achieve this goal by fostering public-private partnerships, encouraging interoperability standards, and reducing or removing outdated regulatory restrictions.

The concept of this “digital transformation” of manufacturing has spread to include many industries such as logistics and transportation, oil and gas exploration, building maintenance, utilities, traffic management and even healthcare. The concept has caught on in a big way, as shown by this map that highlights a number of industry 4.0 initiatives, some of which refer to the trend as “Smart Industry.”

Whatever it’s called, the effects will be far ranging on both businesses and consumers as companies modernize through embracing these transformational technologies.… Read the rest

Can Blockchain Secure the Internet of Things?

In December, a group of companies interested in using blockchain as a tamper-proof method in IoT applications held a meeting, New Horizons: Blockchain x IoT Summit, in Berkeley, California. The goal was to define the scope and implementation of a “smart contracts” IoT protocol layer. This consortium includes startups like Ambisafe, BitSE, Chronicled, ConsenSys, Distributed, Filament, Hashed Health, Ledger, Skuchain, and Slock.it, along with a few large companies like BNY Mellon, Bosch, Cisco, Gemalto and Foxconn.

The consortium agreed thatsecurity, trust, identity and registration and verification would be the cornerstones of any common protocol, while also acknowledging the need for integration and interoperability across multiple chip types, communication protocols, proprietary platforms, cloud service providers, and blockchain systems.

Currently participation in the group is voluntary without any formal membership or governance structures, emphasizing fast-moving open source collaboration.… Read the rest

AT&T and GE’s Current are Layering New Smart City Services on Existing Infrastructure

On February 27th, AT&T and Current, an in-house startup within GE, announced a joint initiative to connect more cities to the Internet of Things (IoT). As an early example of this partnership, they’re upgrading the existing city-wide lighting infrastructure of San Diego to LED lights,  and using that upgrade as an opportunity to add a new set of sensors that will let them optimize traffic flow and parking availability, triangulate the location of gunshots, and monitor air quality and weather emergencies in real-time.

It’s a clever use of existing infrastructure to save time and money as they bring advanced services to market, with AT&T filling the gap to connect everything up. AT&T’s LTE wireless network will provide the connectivity,  Current will supply the sensors and services to integrate with existing infrastructure, while Intel’s Atom® Processor E3900 and Wind River software will run analytics and extract meta data.… Read the rest

SL Enhances Products with Ability to Monitor Solace VMRs

The application resource monitoring software company SL recently announced a new version of RTView Solace Monitor that extends the monitoring of Solace environments to include not just appliances, but Virtual Message Routers. In the words of SL COO Ted Wilson, “as Solace enables customers to expand their infrastructure into the cloud, we want to be sure RTView is ready to meet the needs of messaging across hybrid computing environments.”

Solace Monitor provides several pre-built monitoring displays and pre-configured alert thresholds designed to get you up and running quickly with no agents and no programming required. Now users can get real-time visibility into all aspects of their message routers including VPNs, bridges, clients, endpoints, capacity analysis, Syslog and alerts. And RTView’s distributed architecture intelligently handles global deployments without flooding network bandwidth.

As enterprise applications move to public clouds or get deployed across hybrid clouds, middleware deployments get far more complex and end-to-end application monitoring becomes crucial.… Read the rest

Understanding IoT Protocols – Matching your Requirements to the Right Option

The Internet of Things is finally happening at mass scale as the cost of the sensors, networks and computing power has made the economics work. There are many articles on the web that focus on the sensors, the processes and the opportunity for analytics to drive new efficiencies using IoT, so I will focus on how the data moves from place to place within the architecture. I have also written a blog post called  “Why IoT Needs Messaging” that you might find interesting.

In an IoT architecture there are four different kinds of connections across which data moves:
1) device to device, 2) device to gateway, 3) gateway to data system and 4) between data systems.

Why the Internet of Things Needs Messaging

The number of devices connected to the Internet of Things (IoT) surpassed the number of smartphones and personal computers some time ago, and will overtake the number of people on the planet this year.  Gartner estimates that over 20 billion devices will be connected to IoT by 2020, growing at about 30 percent annually.

Most IoT projects involve only a few hundred or thousand connected devices, but even a seemingly simple application can require hundreds of thousands of connections between devices and generate millions of information updates a second depending on the frequency of updates from those devices.

An IoT architecture with many devices, intermediary nodes (where aggregation and processing may occur) and back-end systems like applications and analytics engines was once an extreme example of distributed computing, but is the new norm.


With so many nodes as part of a single application, you can be sure that something will always be wrong somewhere – devices will need repair, the aggregating nodes will break or reach capacity, or some datacenter asset will be offline. … Read the rest
