Abstract:
The future of computing points to cloud services remaining deeply embedded across sectors. As cloud technologies converge with edge networks and connected devices, resilience and security are no longer secondary technical issues but central policy concerns. This paper shows that resilience is strengthened not by isolation or localisation mandates, but by preserving architectural choice, interoperability, and competitive multi-cloud options across the lifecycle. Many of the decisive factors that affect resilience occur at onboarding - how a cloud provider, tools, licences, and security controls are selected and integrated - and whether workloads and safeguards can in practice be reconfigured, substituted, or exited during disruption. Across business, standards, cybersecurity, and competition communities, resilience is understood as a structural property of architecture, governance, and contractual control. The key test is whether organisations retain credible choices at every stage of the cloud journey, from migration to multi-cloud to exit. Concentration becomes a risk only when portability and switching are restricted in practice.
