Abstract:
UCLA’s PPS system which hosts UCLA, UCM and UCOP payroll data was replaced with the UCPath system in Nov 2018. However, the system is still being actively used by broad set of users. Driven by dwindling system expertise, mainframe retirement, and to align with our cloud strategy we are in the process of migrating all associated datastore to the UCLA data lake solution being built on AWS from scratch.
In this presentation we will be sharing our journey of identifying the data assets, current and future access requirements, the design and development of the data lake on the AWS platform and the lessons learnt during migration.
