BASMATI Final Review meeting Architecture Control Raw data VPN for bulk wifi data - On site at das fest the basmati platform on a hardware machine controls a set of raspberry pis. In the cloud, the basmati platform in a virtual machine controls all aspects of application resource deployment. One scalability engine allocates pis for wifi data sensing at strategic places on the festival site. The other scaling engine responds to signals from the load balancer to accommodate trilateration with real-time signal load. Raw wifi sensing data is transmitted by the pis to the on-site BASMATI and from there it is send over a satellite in bulk to the Basmati Cloud. The clustering signals components pulls the wifi data from the BASMATI cloud, groups it by MAC address and time period and sends it to the load balancer who makes it available to the trilaterators upon request. Trilaterators are calculating the geo positions of single festival users (i.e. MAC addresses) by means of the different wifi signal strengths perceived by the pis. The geo positions are stored in a Mongo DB from where the visualization reads the time coordinated data. The monitoring component allows real time KPI observation of monitoring data provided by BASMATI cloud. Processed data Monitoring data 10/10/2018 BASMATI Final Review meeting 10

BASMATI Final Review meeting Evaluation results Functional suitability: very good Performance: excellent Time behaviour: Transferring and computing over 7 million single data sets (~1GB of data) in these 3 days was not an issue Resource utilization: on-site: 8GB RAM, 4 Cores, 1TB disk (not used completely), in the cloud: 4GB, 2 cores, 40GB disk Mean time to provision new instance and deploy trilaterator: 50 sec Mean time to scale trilaterator: 1min 41 sec Compatibility: good 10/10/2018 BASMATI Final Review meeting 21

BASMATI Final Review meeting Evaluation results Usability: UI Design could be improved Reliability: excellent 100% availability Security: All security requirements for the demo fulfilled Maintainability: good Overall Ease of use: could be improved Usefulness: Very useful Documentation: Available, but distributed over many sources 10/10/2018 BASMATI Final Review meeting 22

BASMATI Final Review meeting Evaluation results Overall the use case development, deployment and operation with BASMATI was compared to other solutions very efficient and reliable. Support from BASMATI partners was necessary for the first deployment but could be done by any dev-op in the future. Some graphical interfaces could be improved but all relevant functionality was available. 10/10/2018 BASMATI Final Review meeting 23
