A microservice series will be made in which we will be able to track the temperature, air quality, and average electricity consumption of the classrooms in the schools. 3 different sensors will be simulated and generate data in seconds. This generated data will be read by the REST API (producer) and added to the queue. The REST API(consumer) side will again process the processing of the data added to the queue and save it to the database. In case of an error, the error logs to Mongodb will be processed with another API. Finally, a Reader API has been developed to read all the data and keep track of error logs, and everything in the system can be analyzed or monitored using this API.
- 3 different databases will be used in the system.
- All Services will be written in NodeJS.
- Docker technology will be used as the development environment.
- Docker files with Nodejs Microservice bone structure were created and distributed to all students.
- A short-term cache structure will also be used with Redis.
- The project was explained to the students at the introductory level.
- All students will work in clusters in groups of 6 people.
- At the head of each group will be a router and an Inavitas employee who will help each router. Figure 2 also lists the working groups.
- In Figure 1, the outline and structure of the project are shown in a diagram.
