In-Network Computing for App-Centric Micro-Services
draft-sarathchandra-coin-appcentres-02
Abstract
The application-centric deployment of 'Internet' services has
increased over the past ten years with many million applications
providing user-centric services, executed on increasingly more
powerful smartphones that are supported by Internet-based cloud
services in distributed data centres, the latter mainly provided by
large scale players such as Google, Amazon and alike. This draft
outlines a vision of evolving those data centres towards executing
app-centric micro-services; we dub this evolved data centre as an
AppCentre. Complemented with the proliferation of such AppCentres at
the edge of the network, they will allow for such micro-services to
be distributed across many places of execution, including mobile
terminals themselves, while specific micro-service chains equal
today's applications in existing smartphones. We outline the key
enabling technologies that needs to be provided for such evolution to
be realized, including references to ongoing IETF work in some
areas.
