Integration of Blockchain with AWS and Azure for Enhanced Cloud Security and Compliance in Multi-Cloud Architectures

The research work proposes the integration of blockchain with AWS and Azure to enhance cloud security and assure compliance in multi-cloud architecture. Using real-world datasets, such as anonymized security logs and compliance records from public cloud repositories, this paper examines the possibility of blockchain providing immutable audit trails, secure transaction records, and automated compliance verification. Our approach integrates blockchain protocols into the AWS and Azure environments to increase trust and transparency while reducing the inherent vulnerabilities of distributed cloud systems. We show, through a series of experiments and analyses, that blockchain not only streamlines the enforcement of security policies but also improves incident response times to reduce the risk of data breaches and unauthorized access. It is a source of credible insights for the enterprises seeking to get their way around modern multi-cloud deployments in order to have robust, compliant, and secure infrastructures.
