Expelliarmus is a novel semantic-centric approach to VMI management system in IaaS Clouds that helps to
minimize storage, publish and retrieval overheads. It incorporates three complementary features:

1. VMIs are modelled as semantic graphs to expedite the similarity computation between multiple VMIs.
2. Semantic-aware VMI decomposition and base image selection to extract and store non-redundant base image and software packages.
3. Assemble VMIs based on the required software packages upon user request.

The research activity is focused on the optimized monitoring and measurement techniques purposely tuned for data-intensive
applications able to offer fine-granular performance statistics collection with controlled overhead at the exascale.
The underlying challenge consists in providing techniques for monitoring resource utilisation and instrumenting of the scalabale applications without causing large overheads in the instrumented system.

The research activity is focused on the auto-tunable system design (mathematical models, algorithms), which effciently performs orchestration of the massive data-intensive processes of the exascale systems while keeping in consideration the set of constraints. The underlying challenge consists in selection of tunable parameters space, optimization objectives and strategies for optimized (static, dynamic) control.
The optimization space created by these tunable parameters will be used as the core for the online scheduler operation that possibly considers multiple conflicting goals such as execution time, energy
and efficency by varying the tunable parameters.

Askalon is an Execution Engine, which supports workflow executions in:

1. different Clouds (Amazon EC2, OpenStack, etc.)
2. Cloud simulations (Groudsim), and
3. Fog

As part of Askalon, a performance monitoring tool stores workflow execution traces in a PostgresSQL database.

ARTICONF researches and develops a novel set of trustworthy, resilient, and globally sustainable decentralised
social media services. ARTICONF addresses issues of trust, time-criticality and democratisation for a new
generation of federated infrastructure, to fulfil the privacy, robustness, and autonomy related promises that
proprietary social media platforms have failed to deliver so far.
