The Kaa IoT Cloud is quite easy to get started with, even with no prior IoT development experience. You are not required to use a console for usual tasks and you can build an end-to-end IoT application - from connecting a device to tracking telemetry and doing analytics - only by the means of the Kaa graphical UI. Adding a new device to start tracking its telemetry only takes a few steps in Kaa. So, you may spend only a few hours and have your complete PoC ready on Kaa.
On the other hand, Kaa also provides advanced capabilities for deploying new microservices, building multiple applications for a single device, configuring reusable device context for dashboards, etc. Mastering those capabilities may take a bit longer, so make sure you refer to our tutorials and documentation for the best results.
