Web Services Relocation and Reallocation for Data Residency Compliance
Pankaj Sahu, Shubhro Roy, Mangesh Gharote, Sachin Lodha · 2023
Compliance with data residency regulations is a huge challenge for most enterprises and cloud service providers. With the emerging data regulations, enterprises need to intermittently review their web service deployment decisions. To be compliant, enterprises need to relocate and reallocate some of the non-compliant users and web services. It can be obtained by minimal or relatively large migrations; however, it has implications over cost.In this paper, we propose an optimization model for web services relocation and reallocation problem (referred to as WSLAP-Repair). The goal is to achieve minimal reallocations with lower additional operational costs while meeting the latency requirements of the concerned web services. We propose a novel heuristic for solving WSLAP-Repair problem. We demonstrate our results on small problem instances using an integer programming open-source solver.
