Serverless cloud platforms promise highly elastic and scalable services without having to care about infrastructural concerns or billing of idle periods. After four years of availability of Function-as-a-Service (FaaS) and related serverless services, it is time to look into their actual use and general properties of serverless computing which propagate into established cloud services. This talk summarises recent technological advances, research results as well as interviews conducted with key industry people on challenges for more complex applications and what to expect next. The metrics presented in the talk are rooted in the automated data analysis of over 80 technical publications on serverless systems. The talk therefore helps in understanding the essence of the ongoing shift to purely and hybrid serverless software development.
