Microsoft bets on a real-time operating system for IoT devices with Express Logic acquisition
The devices that make up the internet of things require a different approach to computing, which is one of the reasons why Microsoft just agreed to acquire a company known for its specialized IoT operating system.
Express Logic, the San Diego company behind the ThreadX RTOS (real-time operating system), is joining Microsoft’s Azure division in an acquisition deal announced Thursday. Terms of that deal, which will give Microsoft access to 6.2 billion deployments of ThreadX RTOS in embedded devices and other IoT hardware, were undisclosed.
Microsoft has not been shy about making the industrial IoT one of the key selling points for Microsoft Azure as part of CEO Satya Nadella’s “intelligent edge” strategy. More and more businesses that operate factories or large real-estate holdings are turning to networks of cheap devices packed with sensors and basic processing power to generate data about their operating environments, in hopes of unlocking more efficient ways of doing business.
But you can’t necessarily slap Windows or even a mobile operating system on to many of these devices, which face significant restraints around how much computing power they can pack into the small spaces where they are usually deployed. Express Logic has been operating in this embedded world for more than 20 years, and the integration of ThreadX RTOS with Azure IoT services will allow Microsoft to make it easier for customers interested in deploying IoT services to get up and running.
“Our goal is to make Express Logic’s ThreadX RTOS available as an option for real time processing requirements on an Azure Sphere device and also enable ThreadX-powered devices to connect to Azure IoT Edge devices when the IoT solution calls for edge computing capabilities,” said Sam George, director of IoT for Microsoft Azure, in a blog post Thursday. Azure Sphere is Microsoft’s current strategy for integrating IoT hardware with a lightweight operating system, and while Microsoft continues to recommend Azure Sphere “for customers’ most secured connections to the cloud,” ThreadX RTOS will now be an option for customers that face significant operating challenges beyond the scope of Azure Sphere, George said.
