Proactive Relocation for Survivable Cloud Services

Paper in proceeding, 2024

Improving the survivability of optical cloud services is costly due to the numerous resources involved. In this work, we introduce a proactive backup storage relocation (PBSR) strategy, which relocates backup storage in advance to better prepare services for potential failures and reduce the need for reactive relocation. Results show that our proposal enhances availability and restorability without increasing the service blocking ratio, while reactive relocations are reduced by a factor of up to half.
