1. Understand Umbra architecture (components and messages);

2. Test Umbra in lab and cloud environments;

3. Create common events in Umbra to exercise chaos engineering mechanisms;

4. Demonstrate the collected metrics of the experiments in umbra dashboards using graphana.;

5. Present reports of the the umbra experiments.

Expected Outcome

Enhance Umbra source code, enable a stable experimentation environment for Umbra in cloud environments with large topologies (e.g., thousands of nodes), generate chaos engineering mechanisms in Umbra, capture the events in dashboards, and generate comprehensive reports detailing an Umbra experiment.

Preferred postgraduate students with notions of Software Defined Networking, and solid knowledge on blockchain project (e.g., hyperledger Fabric and irohaIroha).

Skills

Knowledge about Hyperledger Fabric and Iroha projects, and understanding of software defined networking concepts, with practical experience in emulation environments (e.g., using Mininet).

...

After the successful execution of this internship, Umbra could potentially be a reference platform to conduct scalability tests in Hyperledger blockchains.
