State-machine replication is a concept to achieve fault tolerance. Multiple replicas execute each the same requests on behalf of clients. At the institute we have an own replication framework called SMRteez. As the setup of multiple replicas is complex and error prone, there were initial attempts for a central component that can start, stop and manage replicas from a GUI-based program. The goal of this work is a redesign of this component so that security concerns (e.g., availability of private keys) are considered and the operations are base on a REST interface that can either be operated with a command-line tool or by a web-based single-page application, i.e. a browser GUI. Exact coverage has to be discussed based on the amount of available credit points.

State-machine replication is a concept to achieve fault tolerance. There are several frameworks to support SMR-based applications. Etcd is an application implementing a so-called coordination service. It is internally build with SMR technology, but does not use an underlying framework. The task of this work is to reimplement etcd with the BFT-SMaRt/SMRteez framework. The goal is to demonstrate that the framework can handle such applications. In case of a Bachelor's thesis, in case of remaining time also in case of project work, the performance shall be compared to the original etcd implementation.
