CESNET is an association of universities and the Academy of Sciences of the Czech Republic. It operates and develops the Czech national e-infrastructure designed for the needs of science, research, development and education. It provides a wide range of services for data transmission, storage and processing. These include powerful computing clusters, large data storage for data sharing, multimedia communication tools, and distributed team collaboration environments. The main attention is paid to secure communication, data protection and gradual modernization of the e-infrastructure through the results of own research. CESNET is part of the pan-European GÉANT backbone network and the EGI grid infrastructure.
The main components of e-infrastructure include:
- high-performance national communications infrastructure,
- national grid and cloud infrastructure,
- the most powerful, cutting-edge supercomputing systems in the Czech Republic
- high-capacity data repositories.

CERIT-SC
CERIT-SC (CERIT Scientific Cloud) is a national centre that runs computing and data infrastructure for research and development. With a computing power of over 6,000 CPU cores and 10 PB of storage, it is an important node in the MetaCentrum computing infrastructure. Aside from utilising its own resources, CERIT-SC also conducts research activities that cover e-infrastructure development and interdisciplinary research and development with research partners from various scientific disciplines, where it primarily contributes its experience in the areas of HPC, data analysis, artificial intelligence, bioinformatics and LifeScience. CERIT-SC contributes to a number of international infrastructure and research projects (ELIXIR, numerous EOSC projects, EDIReX, CETOCOEN Excellence, ...).
CERIT-SC is part of the Institute of Computer Science of Masaryk University.

IT4Innovations National Supercomputing Center
IT4Innovations National Supercomputing Center is a leading research, development, and innovation centre active in the field of high-performance computing (HPC) and data analysis (HPDA). IT4Innovations operates the most powerful supercomputing systems in the Czech Republic, which are provided to Czech and foreign research teams from both academia and industry. IT4Innovations currently operates four supercomputers, to which a brand new petascal system with computing power approximately 15.2 PFlop/s will be added in 2021.
The key research areas of IT4Innovations include big data processing and analysis, machine learning, development of parallel scalable algorithms, solution of computationally demanding engineering problems, advanced visualization, virtual reality, modelling for nanotechnologies, and material design.
IT4Innovations is part of the VSB – Technical University of Ostrava.
