Cloud systems, as any other system, must be reliable. This means that the system should respond correctly in presence of failures, which are quite probable in a distributed, largely independent, system as cloud systems ...

Cloud systems, as any other system, must be reliable. This means that the system should respond correctly in presence of failures, which are quite probable in a distributed, largely independent, system as cloud systems ...

Due to the widespread adoption of distributed systems when building applications, demand for reliability and availability has increased. These properties can be achieved through replication techniques using algorithms that ...

In this work, fault modeling for simulators that work in the infrastructure as a service of the cloud computing architecture is presented. Due to the increased demand for online services and solutions, cloud computing has ...

The capability of dynamically adapting to distinct runtime conditions is an important issue when designing distributed systems where negotiated quality of service (QoS) cannot always be delivered between processes. Providing ...

We present a formal characterization of fault-tolerant behaviors of computing systems via simulation relations. This formalization makes use of variations of standard simulation relations in order to compare the executions ...

Industrial processes and technological systems are becoming more and more autonomous and complex. Consequently, the demand for the safety and reliability of these systems is increasing. In this context, process monitoring ...
