“…Event-driven architectures are becoming more prevalent recently in multiple technological paradigms, with message brokers being the cornerstone of these architectures [54]. One of the best implementations of these message brokers are content-based publish-subscribe systems (CBPS) because of their ability to allow subscribers to specify their interests and only receive notifications according to those interests, as opposed to the processing overhead that subscribers to topic-based publish-subscribe systems have to perform [53,55,44,52].…”

“…Therefore, it has been opted for a content-based publish-subscribe distributed system to evaluate the implementation of this work. More specifically, E-SilboPS [44,53,52,45] has been used, which is a content-based publish-subscribe system specifically designed to be elastic due to its scaling algorithm. Its architecture is inspired by other CBPS like SIENA [11,10] and E-StreamHub [8].…”

“…This middleware is the elastic version of SilboPS and was born as a result of a doctoral thesis [51] of which this work is its natural continuation. In addition, it has acquired great relevance as shown by its integration with technological paradigms that demand high performance and are transforming our lives such as Internet of Things (IoT), Smart Cities, Fog Computing [52,53,44], and more generally, in any event-driven architecture [54].…”

“…More specifically, E-SilboPS was conceived as a content-based publishsubscribe middleware specially designed to be elastic [53,44,52]. It is a distributed system composed by four layers of operators (Connection Point, Access Point, Matcher and Exit Point) forming a directed acyclic graph (DAG).…”

“…This is a frequent use case nowadays, since the features offered by the cloud can be exploited by these middlewares to achieve the high performance required by this type of new technological paradigms. For this reason, E-SilboPS was selected, since it is a context-aware content-based publish-subscribe (CBPS) middleware, specially designed to be elastic in cloud environments [53,44]. To this end, it is composed of four layers of operators (Connection Point, Access Point, Matcher and Exit Point) that can scale independently using the cloud resources provided by the IaaS.…”

These lines should serve to name all those people who have directly or indirectly supported and encouraged me over the years, without whom this work would not be a reality today. However, I am aware that most of them will not be mentioned. Please serve these lines to express my gratitude and my consideration to them. I would like to make a special mention to my directors of Thesis, Doctors Javier Soriano Camino and David Lizcano Casas, whom I hold in high esteem and admiration. Without their experience, advice and guidance, this work would not have been possible. Your contribution throughout the process of making this work is of great value.Con todo ello, se puede concluir que es posible escalar de forma automáticas servicios cloud mediante el uso de sistemas de auto-escalado que permitan (i) cumplimiento y adherencia a las SLAs especificadas por los consumidores cloud, (ii) detección automática de los recursos computacionales que son el cuello de botella, y (iii) la monitorización de las métricas esenciales para la toma de decisiones de escalado en entornos multi-cloud.

Cloud computing has been consolidated as a support for the vast majority of current and emerging technologies. However, there are some barriers that prevent the exploitation of the full potential of this technology. First, the major cloud providers currently put the onus of implementing the mechanisms that ensure compliance with the desired service levels on cloud consumers. However, consumers do not have the required expertise. Since each cloud provider exports a different set of low‐level metrics, the strategies defined to ensure compliance with the established service‐level agreement (SLA) are bound to a particular cloud provider. This fosters provider lock‐in and prevents consumers from benefiting from the advantages of multi‐cloud environments. This paper presents a solution to the problem of automatically translating SLAs into objectives expressed as metrics that can be measured across multiple cloud providers. First, we propose an intelligent knowledge‐based system capable of automatically translating high‐level SLAs defined by cloud consumers into a set of conditions expressed as vendor‐neutral metrics, providing feedback to cloud consumers (intelligent tutoring system). Secondly, we present the set of vendor‐neutral metrics and explain how they can be measured for the different cloud providers. Finally, we report a validation based on two use cases (IaaS and PaaS) in a multi‐cloud environment formed by leading cloud providers. This evaluation has demonstrated that, thanks to the complementarity of the two solutions, cloud consumers can automatically and transparently exploit the multi‐cloud in many application domains, as endorsed by the cloud experts consulted in the course of this study.

The Internet of Things is paving the way for the transition into the fourth industrial revolution with the mad rush of connecting physical devices and systems to the internet. IoT is a promising technology to drive the agricultural industry, which is the backbone for sustainable development especially in developing countries like those in Africa that are experiencing rapid population growth, stressed natural resources, reduced agricultural productivity due to climate change, and massive food wastage. In this paper, we assessed challenges in the adoption of IoT in developing countries in agriculture. We propose a cost effective, energy efficient, secure, reliable and heterogeneous (independent of the IoT protocol) three layer architecture for IoT driven agriculture. The first layer consists of IoT devices and it is made up of IoT driven agriculture systems such as smart poultry, smart irrigation, theft detection, pest detection, crop monitoring, food preservation, and food supply chain systems. The IoT devices are connected to the gateways by low power LoRaWAN network. The gateways and local processing servers co-located with the gateways create the second layer. The cloud layer is the third layer, which exploits the open source FIWARE platform to provide a set of public and free-to-use API specifications that come along with open source reference implementations.
