Scope

This line addresses the infrastructure properties that make systems reliable at scale: information security and human factors in security, cloud and serverless architectures, parallel and massive data processing, performance and scalability, and computational sustainability, including software energy consumption. Projects combine performance research with real applications in public agencies and in the center’s own platforms.

Research questions

  • How do cloud and serverless architectures reduce cost and processing time for scientific workloads?
  • Which human factors explain security failures in organizations and how can they be mitigated?
  • How can the energy and environmental cost of software systems be measured and reduced?

Main methods

  • Performance benchmarks
  • Cloud infrastructure experiments
  • Surveys and user studies
  • Incident analysis
  • Software energy consumption measurement
