Cloud computing has revolutionized information technology by offering scalable, flexible, and cost-effective computing solutions. However, its architectural reliance on virtualization, distributed storage, and multi-tenancy introduces persistent security and privacy challenges. Data breaches, cross-tenant vulnerabilities, regulatory uncertainty, and governance gaps remain significant obstacles in both sustainability and companies wanting to implement cloud computing.
Research demonstrates that while encryption and infrastructure safeguards provide meaningful protection, performance trade-offs and policy limitations continue to hinder comprehensive security. Effective cloud security requires a layered approach that integrates technical controls, secure virtualization design, identity management systems, advanced cryptographic techniques, and structured governance frameworks. As organizations increasingly depend on cloud services, addressing these challenges will be essential to maintaining trust, protecting sensitive information, and ensuring sustainable technological innovation.
