IoT (iot.telekom.com/en) is a group of projects related to the field of Internet of Things. Each project is a secure, highly-available and flexible set of micro-services that provides the communication of various smart devices between each other and with the users via different APIs (like REST and device specific ones) and user interfaces. The projects are based on Java Web and modern JavaScript frameworks in a Cloud Environment that includes:

  • Cloud infrastructure provided by Microsoft Azure IoT Hub
  • Platform orchestration by Kubernetes
  • Technology stack: Java, Node.JS, Spring Boot, Spring Cloud, Angular, Vue.JS

The specification is stored in Confluence, we do Scrum and create User Stories in Jira with support of Xray Test Management plugin.
To describe requirements and test cases we use BDD with Cucumber.
CI/CD is implemented with GitLab.

IoT Hub is an all-in-one solution based on micro-service architecture, that provides ability to manage smart devices. Fundamental idea is to standardize interfaces of control and take upon itself all the complexity of integration with various IoT platforms and mobile operators services. Consequently IoT Hub is a universal point of entry for our clients, that provides a comprehensive REST API. Join us if you would like to be at the origins of the IoT future.
