With the advent of cloud-based systems, cloud operators have been aiming at reliable, secured, privacy-preserving and cost-efficient cloud design and management. The fifth annual International Workshop on Cloud Computing Systems, Networks, and Applications (CCSNA) focuses at the intersection of scientists, researchers, practitioners and students from diverse domains in Cloud computing research. The workshop aims to attract contributions of system and network design that can support existing and future applications and services. Researchers are encouraged to submit original research contributions in all major areas, including networks, big data, security, and much more. Submitted papers must represent original material that is not currently under review in any other conference or journal and has not been previously published. All submitted papers will go through a peer review process. The conference is in Washington D.C., December 4 – 8, 2016. The deadline to submit papers is July 1, 2016; selected authors will be notified on September 1, 2016. For more information, visit the IEEE CCSNA website.
