Controllers

Kubernetes orchestration and operator patterns Kubernetes helps with scheduling, scaling, and healing, but many apps need more than generic resources. Operator patterns bring domain knowledge to lifecycle tasks like upgrades, backups, and complex maintenance. They turn a running system into a living creature that can be managed by Kubernetes itself. An operator is built around a Custom Resource Definition (CRD) and a controller. The CRD lets you declare a new kind of resource, and the controller watches those resources to make the real world match the desired state described in the spec. This separation keeps day‑to‑day apps simple while giving operators full control over their lifecycle. ...

Industrial Automation with Sensors and Controllers Industrial automation relies on sensors to monitor conditions in real time and on controllers to decide what to do next. This pairing creates fast, repeatable actions that improve quality and safety on the factory floor. A simple example is a pasteurizer: the sensor reads temperature, the controller compares it to the setpoint, and an actuator adjusts the heater or valve to maintain steady conditions. ...
