Serverless architectures are Cloud infrastructure that incorporate third-party “Backend as a
Service” (BaaS) services, and “Functions as a Service” (FaaS) platform where custom code run in
managed, ephemeral environments triggered by events. Customers of Serverless architectures
may benefit from significantly reduced operational cost, complexity, and engineering lead time,
at a cost of increased reliance on vendor dependencies and comparatively immature supporting
services. At the same time these platforms can provide a great scalability in a fine-grained payper-use model. From a Platform provider perspective, instead the employment of a FaaS allows
to enable per function optimization (eg. Use of specialized hardware, smart scheduling) to
reduce operativity costs and optimize hardware usage.
