Etienne Rivière gave a keynote talk last week to the 32nd IEEE Symposium on Reliable Distributed Systems (SRDS 2013), closing the pre-symposium workshop day (Workshop on Planetary-Scale Distributed Systems, PSDS 2013, and 2nd International Workshop on Dependability Issues in Cloud Computing, DISCCO 2013). SRDS is a top-tier forum for researchers and practitioners interested in distributed systems design, development and evaluation, particularly with emphasis on reliability, availability, safety, security, trust and real time.
