Container Allocation and Deallocation Traceability using Docker Swarm with Consortium Hyperledger Blockchain

Container-based virtualization enables the dynamic allocation of computational resources, thus addressing needs like scalability and fault tolerance. However, this added flexibility brought by containerization comes with a drawback: it makes system monitoring more challenging due to the large flow of calls and (de)allocations. In this article, we discuss how recording these operations in a blockchain-based data structure can facilitate auditing of employed resources, as well as analyses involving the chronology of performed operations. In addition, the use of a blockchain distributes the credibility of record integrity among providers, end-users, and developers of the container-based solution.
