Graphical Federated Cloud Sharing Markets

Small ‘boutique’ clouds challenging the big three (AWS, Azure, Google Cloud) on speed, cost, flexibility, on-prem, and hybrid cloud options are slowly on the rise. This paper comments on the work by Pal
et al.
, in 2020, in relation to the efficiency of practical federated small cloud (SC) resource (e.g., VMs) sharing market structures at a market equilibrium. While the work by Pal
et al.
, in 2020, guarantees a unique, stable, and efficient sharing equilibrium, it falls short of providing a microscopic view into practically likely sharing network structures (graphs) among SC providers in the market and their effect on market efficiency. Consequently, we envision a graphical federated cloud sharing market and comment on its efficiency guarantee at the market equilibrium. While a symmetric graphical small cloud resource sharing economy is pure-strategy efficient (like in the work by Pal
et al.
, in 2020) an asymmetric one generates inefficiencies that improves with an increased number of SCs in the sharing market.
