Development of scientific computing infrastructure significantly influences on various fields of science that require complex computational problems solving and unified sets of commonly used services providing. In Moldova over the last years such computing infrastructures as Grid and HPC have started deploying, but new technologies and new applications domains have led to new approaches of providing computational resources and services. Service oriented infrastructures based on Cloud paradigm simplify the use of distributed computing infrastructure, expand users community and applications areas. In the paper the results of federated Scientific Cloud infrastructure deployment in Moldova are described.
