JerryScript is a lightweight JavaScript engine for resource-constrained devices such as microcontrollers. It can run on devices with less than 64 KB of RAM and less than 200 KB of flash memory.
If the client micro service requires reloading the configuration data dynamically at runtime and it is not based on Spring Cloud Consul (if yes, see the next section), it needs to implement a callback API to do the reloading action.
Core Data Service includes the device/sensor collected data database and APIs to expose the database to other services as well as north bound integration
