The e-commerce ecosystem has the secure handling of transaction data in the cloud to ensure that sensitive information of customers is at bay. With the increasing volume of data and growing threats at the cyber level, it remains one of the biggest challenges in ensuring integrity and scalability in data for e-commerce platforms in the modern world. This study develops an efficient secure and scalable framework for handling transaction data related to e-commerce in the cloud using modern encryption techniques and control access mechanisms. The methodology collected data and pre-processing it, followed by BitLocker encryption, role-based access control (RBAC), and cloud storage for storing secured data management. Results prove that encryption time varies linearly with file size from 1000 ms by 2MB to 9000 ms by 20MB, while system load has a powerful effect on latency, raising 120 ms at load 1 to 460 ms at load 7. This research exhibits that there is a possibility to guarantee safe and scalable data storage while also optimizing system performance for cloud-based e-commerce environments.
