IN2 Group employees and their users presented the company’s experiences and projects at the Windays18 conference last week in Poreč.

Mirjana Jurković from IN2 and Tanja Magdić Ukalović from the Ministry of Justice presented an API developed by IN2 with the aim of enabling data export from the Court Registry, a database of the Ministry of Justice that contains basic information on companies registered in the Republic of Croatia. Once the API is available, developers will be able to access the data in a machine-readable form, in accordance with open standards, and its purpose is to increase the availability of data and make it easier to use. The technologies used on-premises are Oracle and Oracle Report, a Rest API was made using Java for a part of the solution, and Azure SQL, Azure Data Factory and Azure API Management were used from Azure services.

Luka Jelkovac from the Water Supply and Sewerage Karlovac presented a system for controlling the losses in the water supply network of the city of Karlovac. The problem is immanent to whole Croatia since the losses represent about 50 percent of the included water, and the solution to the problem is the IN2Water – a software solution for monitoring water supply losses in real-time. In Karlovac, water consumption data is collected from technical and business systems (SCADA, ERP, Billing, GIS…), transferred and stored for analysis using the Internet of Things and Microsoft Azure Cloud. On the basis of the analysis, water loss spots can be identified, anticipate system behavior in the future and manage more efficiently infrastructural maintenance and repair facilities, as well as the entire water supply network.

Ivana Hrga, BSc, PhD from Andrija Štampar Teaching Institute of Public Health presented the Eco map of Zagreb. It is a project that integrates different data on the state of the environment, such as air quality, meteorological information, as well as data on water and soil quality, and pollen levels. Data is publicly available to citizens as information about a quality of life, while decision-makers and professionals use the data to track spatial and temporal trends of harmful factors and timely react to potential challenges. This Smart City solution applies IoT and Cloud technologies for collecting and mapping ecological parameters in real time. Microsoft Azure Cloud enabled delivery of the solution to Software as a Service model, and the project was implemented by IN2 with its partners – Fornax d.o.o and Hebe d.o.o.

Mario Grdiša from IN2 talked about the challenges that the Azure platform puts before system engineers. Azure is not limited to Microsoft services only, but offers a handful of other technologies. The emphasis of the session was on setting up the open source Apache Tomcat server, which is often used to accommodate applications. Grdiša spoke of the possibilities of monitoring and management, that is, in what way system administrators can configure and adjust the Tomcat server to accommodate the desired application.
