HAAC: Highly Available Access to Credentials, with DHTs

As the realm of Big Data gains momentum, driven by the ever-increasing volume of information that continuously needs to be stored and processed, the problem of availability becomes pressing. The current work addresses this high-impact problem, by using a novel approach to build a decentralized, distributed database for user credentials. This implementation leverages the peer-to-peer DHTs, as their decentralized architecture enables efficient data management and replication in a distributed environment. In the context of the broad market of traditional database technologies, this work can be integrated into applications as the underlying storage solution, in a seamless and transparent manner for the application that uses it. High availability and fault tolerance, inherited from the DHT, are exhibited through experimental evaluation and rigorous analysis of the results, illustrating the viability of this original solution.
