The aim of the thesis was to improve the performance of an existing information system based on microservice architecture. In the thesis a prototype was implemented for more efficient event matching alongside the current implementation. The success of implemented changes was evaluated by performance testing. The most important indicators of success used were CPU load and the execution speed of aggregation algorithm. Prototype implemented in this thesis was faster based on performance test results. The average CPU load was smaller, and the execution speed of aggregation algorithm was faster for the most parts.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-06-20T07:31:24Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-06-20T07:31:24Z (GMT).
