English abstract:
Cloud-based elastic systems run on a cloud infrastructure
and have the capability of dynamically adjusting the alloca-
tion of their resources in response to changes in the work-
load, in a way that balances the trade-o between the desired
quality-of-service and the operational costs. The actual elas-
tic behavior of these systems is determined by a combination
of factors, including the input workload, the logic of the elas-
tic controller determining the type of resource adjustment,
and the underlying technological platform implementing the
cloud infrastructure. All these factors have to be taken into
account to express the desired elastic behavior of a system,
as well as to verify whether the system manifests or not such
a behavior.
In this paper, we take a rst step into these directions, by
proposing a formalization, based on the CLTLt(D) temporal
logic, of several concepts and properties related to the be-
havior of cloud-based elastic systems. We also report on our
preliminary evaluation of the feasibility to check the (for-
malized) properties on execution traces using an automated
verification tool.
