Abstract

This study focuses on designing a DevOps centered strategy for a resilient multi-cloud disaster recovery. It targets managed Kubernetes clusters deployed on Google Cloud Platform (GCP) and Azure, utilizing open-source tools to enhance flexibility, mitigate vendor lock-in, and streamline the disaster recovery process. A CI/CD pipeline is established to increase the efficiency of disaster recovery across cloud providers. The research evaluates Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) for containerized applications rolled out on GCP & Azure, specifically in scenarios involving software upgrades and area wide power outages/datacenter failures. The aim is to offer an alternative to cloud specific tools, enabling migration and restoration across cloud service providers post disaster. The developed pipeline explores variations in RTO & RPO amongst distinct cloud providers for the same application stack. The findings reveal GCP’s efficiency in restoring applications after a system upgrade failure, while Azure demonstrates quicker migration and restoration capabilities in datacenter failure scenarios.
