With a Mobile Cloud Computing (MCC) market value of US$9.5 billion in 2014 and with more than 1 trillion cloud-ready devices in the next four years, MCC is considered as one of today's hottest new technologies in both academia and industry. MCC integrates different major technologies such as smart devices technologies (phones, tablets, watches, …etc), cloud services, big data, and cloud computing in one platform that services the end users. Despite the rapid growth of MCC, many issues are still challenging and need to be addressed. These challenges are related to the underlying networks , cloud services, security, the required Quality of Service, the availability of services, the needed user data management, and many others. The International Workshop on Mobile Cloud Computing systems, Management, and Security (MCSMS) is introduced as a forum for scientists, researchers, students, and practitioners to present their latest research results, ideas, and developments in the area of Mobile Cloud Computing that addresses the aforementioned challenges.

MCSMS 2021 workshop aims to investigate the opportunities and requirements for Mobile Cloud Computing, as well as Fog and Edge Computing domains. The objective of MCSMS2021 is to provide a forum for scientists, engineers, and researchers to discuss their research and results on all aspects of Mobile Cloud Computing (MCC) as well as Fog and Mobile Edge Computing. Researchers are encouraged to submit original research contributions in all major areas, which include, but not limited to:

* Mobile Cloud Computing Systems.
