Welcome to the 10th International Conference on Cloud Engineering (IC2E-2021), sponsored by IEEE and held inperson in beautiful Pacific Grove, CA (near Monterrey, CA) - returning to the Bay Area of California for this 10th anniversary - the location where IC2E started over a decade ago! We are thrilled to be returning to a safe, yet inperson, event this year after being virtual last year due to the COVID-19 pandemic. We look forward to catching up with you, hearing about your latest cloud computing research, socializing in a beautiful setting, and meeting those of you new to IC2E.
