Conventional physical servers had to be acquired, provisioned, and configured beforehand; virtual resources can be allocated on demand, and changes can be managed quickly. Deploying systems on virtualized resources allows one to allocate resources given the actual workload and KPIs of interest, but it requires that resource management be part of the system itself. Traditional application components must be augmented with probes and actuators to sense the application behavior and provision resources accordingly. Big data applications are a prominent example of these modern systems, and the paper discusses dynaSpark, that is, the work done by the authors to extend Spark standalone —a well-known framework widely used for parallel processing and big data applications— and augment it with resource management capabilities. It also introduces the key problems the integration and the particular batch applications bring in, and identifies additional aspects that are still to be taken into account and that would lead to a better solution.

Due to the intrinsically safety-critical nature of ERTMS, software testing must meet the strict prescriptions imposed by the certification authorities, which often require the availability of the entire system. This potentially leads to perform the tests at a late stage of development, even though the best practices suggest that it would be more convenient to test the system incrementally since the early stages of development. This paper deals with the solution we devised to address this issue in a recent ERTMS project. We adopted a design-for-testability pattern which purposely enhances the observability and the controllability of the software under test to make it testable at any stage of development, allowing the exploitation of system tests even during component and integration testing.
