- ReefBeat® is an Internet of Things platform, based on a microservices architecture deployed in a highly available cluster in Google Cloud.
- The microservices, written in Kotlin and developed using mainly the Spring Framework, are encapsulated in a deployable docker container-as-a-service.
- Automated build process enables us to deliver updates safer and in a timely manner.
- The microservices communicate with each other through Kafka messages.
- The firmware powering Red Sea’s hardware devices (such as ReefWave® and ReefLED™) was developed using C++.
- The communication between the devices and the cloud microservices is done through the MQTT protocol.
- The devices are controlled using the ReefBeat® mobile application (developed independently by Red Sea) which is available for both Android & iOS devices. The app communicates with the devices by sending commands directly or via cloud.
- We are using TLS and AES encryption for a secure communication.
- For the central logging, monitoring and alerting system we used ELK Stack (Elasticsearch, Logstash, Kibana), Google Stackdriver, Prometheus and Grafana.
- The front-end development for the admin interface is based on Angular 7, Bootstrap 4, HTML, CSS.
- We’ve based the entire development process on the Agile / Scrum methodology.
Results
The ReefWave® pumps developed by Red Sea ensure a water motion that’s perfect for corals, wherever they are placed in the aquarium. The system is in permanent contact with the ReefBeat® app, and will send notifications to your phone, whenever the communication is lost. The app allows users to set customized programs, with up to 10 distinct wave types daily, with different pump intensities, using the daily schedule. For each pump users can create customized versions for each of the wave types. These can be previewed, selected, edited, or deleted in the Wave Library. The pumps can also be turned off for specific periods of time, while feeding the fish or corals.
