ISC2 Certified Cloud Security Professional (CCSP) Practice Question
Your company is negotiating a contract with a public IaaS provider to host a three-tier application currently running on VMware virtual machines. Management insists that if costs rise or regulations change, the application and its data must be redeployed on-premises within 60 days, with minimal code or configuration changes. Which design decision will BEST address the cloud shared considerations of portability and reversibility specified by management?
Migrate all databases to the provider's proprietary managed database service and export weekly snapshots for backup purposes.
Adopt provider-specific VM images optimized with cloud-native drivers and rely on live migration support when terminating the contract.
Package each virtual machine as an OVF image and run the workloads inside provider VMs that are orchestrated by Kubernetes clusters identical to those maintained on-premises.
Use the provider's autoscaling groups and load balancer services while keeping on-prem source code backups in a version-control repository.
Portability and reversibility require that workloads can be moved between environments without extensive refactoring and that data can be cleanly withdrawn from the provider. Using the Open Virtualization Format (OVF) to package virtual machines avoids dependence on a vendor-specific image format, while containerizing workloads under an orchestration platform such as Kubernetes provides a uniform deployment model that can run both in the provider's IaaS and on-prem clusters. This combination allows the organization to export images and redeploy them locally within the required 60-day window. The other options tie critical components to proprietary services or images, creating technical lock-in that hinders timely exit or redeployment, and therefore do not satisfy the stated shared considerations.
