What Is Serverless Computing?
Serverless computing emerged in the late 2010s “with characteristics that claimed to be different from those of established IT services, including Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) clouds,” write Samuel Kounev, Nikolas Herbst, Cristina L. Abad, and others in the Communications of the ACM.
Despite the popularity of serverless computing, there is still no precise understanding of the term, they state. In fact, “existing definitions of serverless computing are largely inconsistent and unspecific, which leads to confusion.”
The authors propose “a refined definition capturing the essential conceptual characteristics of serverless computing as a paradigm.”
They also review serverless computing applications, discuss open challenges, and provide an outlook on the future of the serverless paradigm.
