This Deliverable D9.2 - "SoBigData e-Infrastructure Operation Report 2" is the revised version of the deliverable D9.1 - "SoBigData e-Infrastructure Operation Report 1" [3]. It reports on the activities carried out within Work Package 9 in the period from M19 (January 2021) to M36 (December 2022) for the SoBigData e- Infrastructure operation activity. It includes a detailed set of usage indicators (i.e., the number of users, access to resources, usage of resources from scientists, etc.). It also reports the deployment and procedures governing the operation of the Virtual Research Environments, the catalogue, and the services devoted to data analytics. A total of 17 Virtual Research Environments (VREs) have been created and/or operated to serve the needs arising in the context of the project. The SoBigData gateway (https://sobigdata.d4science.org/) provide its users with: 6 Exploratories VREs paired with the use cases (Demography, Economy & Finance 2.0; Migration Studies; Societal Debates and Misinformation Analysis; Social Impacts of AI and Explainable Machine Learning; Sports Data Science; Sustainable Cities for Citizens); 4 Virtual Lab VREs - SoBigDataLab and the OpenScienceGraphLab to exploit and experiment tools and solutions, the SoBigData-PlusPlus at DSAA 2021 Lab and the XAISS VLab, conceived to be the working environment for Hands-on Tutorials showing the services provided by SoBigData for the new generation of Responsible data scientists; 3 Applications VREs - TagME, SMAPH, M-Atlas; 2 Project Internal VREs - SoBigData.eu VRE for the communications and collaboration among project and initiative members and SBD-InfraCore VRE for supporting SoBigData++ WP9; 2 Literacy And Training VREs - the SoBigDataLiteracy, supporting Critical Data Literacy of task T.2.4, creating a curated collection of literature of interest for the SoBigData Community, and the e-Learning_Area VRE to host training materials developed within the SoBigData project. As of mid-December 2022, the e-infrastructure served more than 10,000 users by a total of more than 47,000 working sessions, with an average of 1350 working sessions per month with stable trend. This required to deal with approximately 130 issue tracker tickets (65 requests for support, 4 requests for incidents and bugs, 22 requests for new features, and 39 requests for Tasks, Virtual Machine or Container creations).
