Query: Costless: Optimizing Cost of Serverless Computing through Function
  Fusion and Placement   Serverless computing has recently experienced significant adoption by several
applications, especially Internet of Things (IoT) applications. In serverless
computing, rather than deploying and managing dedicated virtual machines, users
are able to deploy individual functions, and pay only for the time that their
code is actually executing. However, since serverless platforms are relatively
new, they have a completely different pricing model that depends on the memory,
duration, and the number of executions of a sequence/workflow of functions. In
this paper we present an algorithm that optimizes the price of serverless
applications in AWS Lambda. We first describe the factors affecting price of
serverless applications which include: (1) fusing a sequence of functions, (2)
splitting functions across edge and cloud resources, and (3) allocating the
memory for each function. We then present an efficient algorithm to explore
different function fusion-placement solutions and find the solution that
optimizes the application's price while keeping the latency under a certain
threshold. Our results on image processing workflows show that the algorithm
can find solutions optimizing the price by more than 35%-57% with only 5%-15%
increase in latency. We also show that our algorithm can find non-trivial
memory configurations that reduce both latency and price.
