Abstract
The rapid advancements in Information and Communication Technologies (ICTs) have enabled the emerging of the “cloud” as a successful paradigm for conveniently storing, accessing, processing, and sharing information. With its significant benefits of scalability and elasticity, the cloud paradigm has appealed companies and users, which are more and more resorting to the multitude of available providers for storing and processing data. Unfortunately, such a convenience comes at a price of loss of control over these data and consequent new security threats that can limit the potential widespread adoption and acceptance of the cloud computing paradigm. In this talk I will illustrate some security and privacy issues arising in the cloud scenario, focusing in particular on the problem of guaranteeing
confidentiality and integrity of data stored or processed by external cloud providers.

Abstract
Due to the current hype around cloud computing, the term “native cloud application” becomes increasingly popular. It suggests an application to fully benefit from all the advantages of cloud computing. Many users tend to consider their applications as cloud native if the application is just bundled in a virtual machine image or a container. Even though virtualization is fundamental for implementing the cloud computing paradigm, a virtualized application does not automatically cover all properties of a native cloud application. In this work, we propose a definition of a native cloud application by specifying the set of characteristic architectural properties, which a native cloud application has to provide. We demonstrate the importance of these properties by introducing a typical scenario from current practice that moves an application to the cloud. The identified properties and the scenario especially show why virtualization alone is insufficient to build native cloud applications. Finally, we outline how native cloud applications respect the core principles of service-oriented architectures, which are currently hyped a lot in the form of microservice architectures.

Abstract
We have covered the planet with sensors, cameras, microphones, drones, tracking devices, you name it. All that data is coming at us with an incredible diversity, volume and speed. It is the goal of the Internet of Things (IoT) to provide an infrastructure that can deal with this paradigm shift in ICT.
Business and industry have already discovered the huge potential the IoT will provide them with. Up to now however the scientific world seems to wait and see.
In this talk I will explore the new science we can expect from using the IoT as an experimental platform to study truly complex systems. The need for that is urgent and knocking at our door: We live in a complex world and are surrounded by complex systems: from a biological cell, made of thousands of different molecules that seamlessly work together, to millions of computer systems that should work together, to our society, a collection of seven billion individuals that try to work and live together. These complex systems display endless signatures of order, disorder, self-organization and self-annihilation.Understanding, quantifying and handling this complexity is one of the biggest scientific challenges of our time. I will discuss ways in which the IoT can help us to make sense of the world around us, to analyze, predict and nudge control its amazing complexity.

Abstract
Ubiquitous computing and modern data collection tools have given rise to a new era of data management, in which the data as well as the processing environments are enormous and diverse. In this era in which the terms Big Data and Cloud Computing prevail, the success of data management relies in optimizing data processing on multiple dimensions and delivering data services with multifarious quality guarantees. In this talk we will discuss the challenges and the opportunities of the new era of data management and we will explore the possibilities and limitations of multi-dimensional data management. We will focus more on the incorporation of the notion of cost in traditional and new techniques and the role of data heterogeneity. The talk will summarize recent work on a novel economy model for a cloud where users pay on-the-go for the data services they receive and user payments can be used for service provision, infrastructure maintenance and profit. The discussion will go further to the requirement of approximately querying big heterogeneous data in such an environment. The talk will conclude with a discussion on the special management requirements of big analytical data collections and how these could be fulfilled employing cloud data services.

Abstract
In Internet of Things (IoT) the devices are interconnected through Internet with several redundant paths, but they are still vulnerable to the effects of large scale disasters such as earthquakes and floods. The disaster area may be disconnected from the rest of the Internet and the need arises to get information about the victims.
Adhoc networks like MANETs and DTNs are most suitable to support the communication in partitioned networks, such as a network in a post disaster situation. Even an adhoc network becomes one of the essential network architecture in IoT and attracted lots of attention in the last decade. The disaster affects the several regions with different intensities called each region as disaster event which are located nearer to each other.
Each disaster event is assigned a group of rescue entities with hand held IoT device, where they perform the tactical operation. The movement pattern of the rescue entities in a post disaster area is described by a mobility model which is used to evaluate the routing protocols for post disaster scenario networks. Existing mobility models for post disaster scenarios do not distribute the rescue entities in proportion to the intensity of disaster events in the case of multiple events occurring simultaneously. In this work, we propose the Role-based 3-Tier Mobility Model (RTTMM) to mimic the movement pattern of different rescue entities involved in the disaster relief operation by distributing them based on the proportion of the intensity of the disaster event.
Our model generates the mobility traces of the rescue entities, which are fed as input to the DTN routing protocols. We also evaluate the performance of existing DTN routing protocols using the traces obtained from RTTMM.
