serverless

 serverless  is doublethink jargon that misleadingly refers to web applications that completely depend on someone else’s servers (rather than no servers as a literal interpretation would imply), often through proprietary function as a service (FaaS) services, like AWS_Lambda, which have been used for experimental IndieWeb building blocks implementations.

There are definitions of that also include backend as a service (BaaS) services, e.g. Serverless Architectures.

IndieWeb members have experimented with services for various building blocks such as Micropub endpoints.

Lock-in
Due to use on proprietary FaaS/BaaS, typical implementations suffer from a lock-in effect, from code that depends on those proprietary APIs, data formats etc.
