Obtaining correct results and behaviour on computing is a
long-standing concern. Such guarantee can be obtained through fault
and intrusion tolerance (FIT) mechanisms, which aim to tolerate
accidental and arbitrary faults. Byzantine fault tolerant
replication, when combined with proactive recovery techniques, can
tolerate any number of arbitrary faults during the entire system
life time. However, common vulnerabilities shared between replicas
can compromise such tolerance. Diversity is a complementary
mechanism that combines diverse resources to increase vulnerability
independence between system components. Obtaining diversity
automatically is a process that can be decomposed into two phases:
creation and selection. The first phase consists in providing
enough diverse resources to be considered, combined and selected in
second phase. In this work we review basic FIT mechanisms, and
analyze diversity in cloud computing environments. We present the
DiversityAgent, a Java library for selecting cloud resources
considering multiple diversity properties. Finally, we integrate
this library with two use cases and evaluate its correctness and
