Bringing Linux containers to small-footprint industrial-edge applications

Developers can create applications that represent their true differentiation.

Linux containers have been broadly used in data centers and IT environments for years. Until recently, they were not easy to use with pre-integrated platforms for embedded market segments such as industrial, energy, medical and transportation. The lack of container knowledge and broad ecosystem collaboration limited their use in small-footprint edge systems, especially in the industrial area.

Let’s explore how such an approach can remove the barriers to container use in applications like IoT gateways, industrial automation control systems, Radio Access Network (RAN) products and a wide range of network appliances.

In the last decade, enterprise IT applications have increasingly been developed around “cloud-native” computing architectures because of their speed, scale and economic benefits. Applications are segmented into microservices, increasing the reusability of individual modules while enabling agile deployment models and improving the efficiency of maintaining the code. Applications are then deployed within containers, where a container integrates the application itself along with all dependent libraries and associated functions, resulting in a quick-loading, standard unit of software that has a minimal footprint. Containerized applications are highly portable between computing environments, since they’re isolated from the underlying compute platform. Orchestrators control the instantiation, scheduling and management of containerized applications to optimize the utilization of compute, memory and storage resources.

Standards-compliant, cloud-native implementations based on open-source projects are possible thanks to the Cloud Native Computing Foundation (CNCF), which serves as the vendor-neutral home for many of the fastest-growing container-related projects. The foundation fosters collaboration between the industry’s top developers, end users and vendors.

While initially deployed in enterprise IT environments, cloud-native architectures and containers provide benefits that are equally desirable for industrial, energy and medical embedded systems located at a factory, hospital or remote site. Code reusability, efficient maintenance, platform independence and optimized resource utilization are just as important for devices and applications developed by small teams working to meet aggressive schedules, deployed across multiple hardware architectures based on a variety of processor architectures.

Our distribution, for example, includes pre-integrated components configured to deliver a fully functional solution for embedded systems such as edge appliances and industrial automation-control systems. By leveraging this pre-integrated container platform, developers can focus on creating the applications that represent their true differentiation, enabling them to accelerate their time-to-market for value-added solutions.
