Abstract
Cloud Computing and Blockchain are two key technologies in modern information
systems. While Cloud Computing provides scalable and flexible resources for data
storage and processing, Blockchain offers a decentralized and secure environment that
ensures data integrity and transparency. This dissertation presents a comparative study
between the two technologies with a focus on security aspects. A practical application
was developed using MongoDB Atlas and BigchainDB to evaluate their performance
and security. The results show that Cloud Computing offers greater flexibility and
efficiency, whereas Blockchain provides enhanced mechanisms for ensuring data
integrity, traceability, and transparency. The study highlights the strengths and
limitations of both technologies and demonstrates their potential contribution to
building secure and reliable information systems.
