Welcome to the 2021 edition of The IEEE World Congress on Services (SERVICES). It has been a privilege to serve as the Chair of the Steering Committee since summer 2017. After having completed three rounds in 2018, 2019 and 2020, we continue to experiment with new ideas and have launched new initiatives in the 2021 edition. First, I am very pleased to announcee that SERVICES and IEEE Trans. on Services Computing (TSC) has signed a multiyear agreement to phase in the Journal-First-Conference-Second (J1C2) cooperation mode, the first of its kind in the Computer Society. We also launched the inaugural edtion of the IEEE International Conference in Digital Health (ICDH) to join the set of conferences already affiliated with SERVICES, namely CLOUD, ICWS, SCC, and SDMS. Due to logistics reason we decided to move 2021 IEEE EDGE to December, still considered as part of the 2021 Congress. Rapid advances of Digital Health (DH) technologies, in conjunction of the pervasive and revolutionary nature of entering an Internet of Things (IoT) era, made us believe that we ought to engage digital healthcare technologies as an integral part of SERVICES. We are fortunate to be able to recruit well known DH pioneers and seasoned researchers in this emerging domain, and have developed a highly robust program with the strong support from US National Science Foundation and National Institutes of Health, and private industry, including IBM. The Steering Committee has been keen in undertaking such an approach to always be on the outlook to timely plan for a new international forum as a new conference, a symposium or a workshop, should any emerging service-centric technologies emerge on the horizon outside our current technology coverage and offerings.
