As IoT systems grow ever more complex, developers are turning to microservices to architectures that make rolling out and updating IoT software faster, easier, and more secure.

A microservice architecture is a loosely coupled framework that uses virtualization to separate system software components into “containers.” The structure of container-based microservice architectures allows IoT developers to deploy software quickly, at scale, and without fear of disrupting software dependencies elsewhere in the system.

It also ensures scalable, interoperable connectivity for new and legacy devices, as containerized protocol and networking support can be added based on the target hardware platform.

These features translate to faster, more iterative IoT software upgrades, more granular codebase management, and better utilization of software engineering resources.
