  With active time-domain surveys like the Zwicky Transient Facility, the
anticipated Rubin Observatory's Legacy Survey of Space and Time, and
multi-messenger experiments such as LIGO/VIRGO/KANGRA for gravitational wave
detection and IceCube for high-energy neutrino events, there is a new era in
both time-domain and multi-messenger astronomy. The Astro2020 decadal survey
highlights effectively responding to these astronomical alerts in a timely
manner as a priority, and thus, there is an urgent need for the development of
a seamless follow-up infrastructure at existing facilities that are capable of
following up on detections at the survey depths. At the W. M. Keck Observatory
(WMKO), we are actively constructing critical infrastructure, aimed at
facilitating the Target-of-Opportunity (ToO) trigger, optimizing observational
planning, streamlining data acquisition, and enhancing data product
accessibility. In this document, we provide an overview of these developing
services and place them in context of existing observatory infrastructure like
the Keck Observatory Archive (KOA) and Data Services Initiative (DSI).
