Rapidly develop Internet of Things apps with Docker Containers
The rapid growth of the Internet of Things (IoT) has been driven in part by the commoditization and accessibility of wireless modules, sensors, and microcontrollers. But the IoT isn't just big news for device manufacturers. As the number and variety of connected devices increases, the demand for applications to interface with those devices and to process the vast quantities of data that they produce is also increasing. To match this growing demand, web and mobile application developers will need to start to develop for the IoT and adapt their current development practices to meet the challenges of this new application area. One such development practice is the use of containers. Containers are a lightweight approach to virtualization that developers can apply to rapidly develop, test, deploy, and update IoT applications at scale.
