Abstract

Resilience has become a priority for organisations seeking to navigate an increasingly complex and unpredictable digital landscape. This thesis investigates the impact of multi-cloud strategies on enterprise resilience by examining factors such as the number of cloud providers, percentage of services distributed, annual IT budget, downtime, incident response time, and redundancy measures. Through a comprehensive literature review and a data-driven approach, this research explores how these variables contribute to the resilience of organisations’ IT infrastructure in the face of disruptions. A multiple linear regression analysis was conducted using data from 1000 enterprises, revealing significant relationships between the independent variables and organisational resilience.

While also incorporating comparative analysis, the study further proposes a framework for increasing enterprise resilience based on the empirical results. This framework emphasises the need for risk management strategies informed by quantifiable data, tailored allocation of resources, effective governance across multiple clouds, and the implementation of redundancy measures to mitigate risks. By providing quantifiable metrics and insights, this research aims to assist organisations in making informed decisions about multi-cloud adoption, to enhance the resilience of their deployments to withstand and recover from disruptions.
