Secure Multi-Tenant Cloud Architectures for Achieving Data Confidentiality, Integrity, and Availability in Heterogeneous Environments
Keywords:
Cloud Security, Multi-Tenant Architecture, Confidentiality, Integrity, Availability, Heterogeneous Infrastructure, Zero TrustAbstract
Cloud computing has transformed IT infrastructures by enabling scalable, cost-efficient services. However, the rapid expansion of multi-tenant cloud environments—especially in heterogeneous infrastructures—raises critical concerns over data confidentiality, integrity, and availability (CIA). The inherent resource sharing among tenants, combined with diverse workloads and configurations, creates vulnerabilities that cannot be addressed by traditional security models alone.
This paper explores architectural strategies that support secure multi-tenancy in heterogeneous environments. It reviews past research on isolation models, evaluates the comparative strength of current architectures like containerized and zero-trust frameworks, and discusses emerging techniques such as service mesh and confidential computing. We conclude that zero trust architectures, when properly implemented, offer the strongest alignment with CIA requirements across diverse systems.
