Titre : An Autonomic Strategy for Auto-scaling Smart Cities Platform Infrastructures

Abstract:

Smart cities application development platforms are complex systems that receive, store, process, and display large volumes of data
from different sources, having several users, such as citizens, visitors, government, and companies. The underlying information
technology infrastructure to support smart cities platforms needs to deal with the highly dynamic workload of the different applications,
with simultaneous access from multiple users and sometimes working with a large number of interconnected devices. Typically, the underlying
infrastructure encompasses cloud platforms that offer an elastic and highly dynamic infrastructure for data storage and computation, capable
of scaling up or down according to the smart cities applications demands. In this talk we discuss the proposal of an atomic strategy for
auto-scaling smart cities platform infrastructures. This auto-scaling strategy follows the MAPE-K control loop to dynamically adjust the
infrastructure in response to workload changes. It supports scenarios where the number of processing requests is unknown beforehand. The
strategy is used in the computational environment that supports the Smart Geo Layers (SGeoL), a platform for developing smart cities applications.
