With developments such as virtualization and cloud computing, system operation (such as installation, deployment, upgrading) has become a significantly more complex task: an operator might be responsible for thousands of machines, which are built and connected in ever more complex ways. Therefore it is important to support operators to make sure that, e.g., an upgrade process is executing correctly and has the desired result.

Our work thus is concerned with (i) discovering how processes are executed for log files, and (ii) making sure a running process corresponds to the correct execution. Initial works of ours have been published - see below.

Multi-instantiation of sub-processes in this context presents itself as follows: certain cloud operation processes have sub-processes that are executed multiple times in parallel, where beforehand it is unknown how many such parallel executions will be required. Previous techniques for process mining do not deal with such cases. We need to adequately discover / check such multi-instantiation as per the previous paragraph, because otherwise our error detection mechanisms cannot deal with a big chunk of cloud operations.

In the context of this work, there are numerous open topics for future research, see

Students will work closely with senior researchers at National ICT Australia (NICTA) in a very friendly, diverse team environment. Suitable for students interested in software design, architecture, and practical industry development methods.
Students will be exposed to latest cloud technologies and advanced methods from business process management / process mining.
