Blockchain-Enabled Resource Orchestration Protocol for Secure Multi-Tenant Cloud Infrastructure Management and Access Control

Security and resource allocation and access control become complicated issues because of increasing challenges in multi-tenant cloud infrastructure management. Resource orchestration through blockchain technology solves transparency shortcomings and auditability issues and trust concerns which occur during multiple stakeholder usage of shared infrastructure. Through smart contracts policy enforcement operates automatically along with cryptographic verification which guarantees isolated tenant spaces. The application utilizes permissioned blockchain technology and cloud-optimized consensus protocols for deployment. Performance evaluations revealed 99.7% correct transactions with 96.8% successful validation of operations among multiple distributed nodes. Resource allocation events showed latencies shorter than 200ms under all peak usage conditions at a 99.3% system availability level. Security assessment results showed that tenants operate in perfect isolation and experienced no unauthorized access between different tenants. The developed protocol achieves success by resolving cloud security limitations between multiple tenants through real-time audit abilities coupled with automated compliance control.
