[E-impact] CASPER: Carbon-Aware Scheduling and Provisioning for Distributed Web Services

[Hesham ElBakoury <[e-mail]>]

This new paper "*CASPER: Carbon-Aware Scheduling and Provisioning for
Distributed Web Services"* [1]. "CASPER is the first framework that
seamlessly integrates server provisioning and request scheduling for a
geo-distributed web application, with a particular focus on interactive web
requests."

*Abstract*
"There has been a significant societal push towards sustainable practices,
including in computing. Modern interactive workloads such as
geo-distributed web-services exhibit various spatiotemporal and performance
flexibility, enabling
the possibility to adapt the location, time, and intensity of processing to
align with the availability of renewable and low carbon energy. An example
is a web application hosted across multiple cloud regions, each with
varying carbon intensity based on their local electricity mix. Distributed
load-balancing enables the exploitation of low-carbon energy through load
migration across regions, reducing web applications carbon footprint. In
this paper, we present CASPER, a carbon-aware scheduling and provisioning
system that primarily minimizes the carbon footprint of distributed web
services while also respecting their Service Level Objectives (SLO). We
formulate CASPER as an multi-objective optimization problem that considers
both the variable carbon intensity and latency constraints of the network.
Our evaluation reveals the significant potential of CASPER in achieving
substantial reductions in carbon emissions. Compared to baseline methods,
CASPER demonstrates improvements of up to 70% with no latency performance
degradation."

What part of CASPER can be standardized by IETF?
