ISC2 Certified Cloud Security Professional (CCSP) Practice Question
Your company is redesigning a customer-facing application so that it can fail over from a public cloud provider to a second provider on short notice. Management insists that the solution minimize vendor lock-in and maximize workload portability. Which design choice best supports that requirement?
Rely on the provider's proprietary IAM service for authentication and authorization across all tiers.
Rewrite business logic to run exclusively on the provider's native function-as-a-service (FaaS) platform.
Package application components into OCI-compliant containers and deploy them on self-managed Kubernetes clusters in each cloud.
Adopt the first provider's fully managed, proprietary NoSQL database service for all persistent storage.
Packaging the application as OCI-compliant containers that you orchestrate with self-managed Kubernetes clusters makes the deployment largely independent of the underlying cloud provider. Both OCI and Kubernetes are open standards supported by all major providers, so you can move the same container images and manifests between environments with minimal re-engineering. The proprietary database, serverless, and IAM offerings tie the workload to a single vendor's APIs and data formats, significantly increasing migration effort and therefore vendor lock-in.
