Frank Leymann is a full professor of computer science, director and founder of the Institute of Architecture of Application Systems (IAAS) at the University of Stuttgart, Germany. His research interests include business process management, service computing, middleware, cloud computing, and pattern languages. The projects he is working on are funded by the European Union, the German Government, or directly by industry partners. Frank contributed to several standards, especially he is one of the original authors of the cloud standard TOSCA. Before accepting his current position he was an IBM Distinguished Engineer and member of a small team in charge of IBM’s middleware stack.
Title: “Cloud Orchestration: Towards Building Manageable Cloud Applications”
Speaker: Prof. Dr. Dr. h.c. Frank Leymann
Summary: We start with arguing that bursting images (or containers) to the cloud is a wrong approach, and that specifying the topology and orchestrations behind an application is the right way. Next, we sketch the TOSCA standard and its current developments. The differences between imperative and declarative processing of topologies as well as corresponding pros and cons are discussed. The open source environment OpenTOSCA is sketched. It is suggested that using patterns to create manageable applications in the cloud is a solid, preferable way. An outlook on a series of projects that are about to begin and that combine cloud and IoT technologies closes the talk.
Antonio Manzalini received the M. Sc. Degree in Electronic Engineering from the Politecnico of Turin. In 1990 he joined CSELT, which then became Telecom Italia Lab, by participating in RT&D activities on optical transport networks. He was actively involved in leading positions in several EURESCOM and EC funded Projects. He chaired ITU-T Questions responsible of all Recommendations on transport networks. He published more than 100 papers and he served as member of TPC of several IEEE Conferences. He is Chair of the IEEE SDN initiative (http://sdn.ieee.org/). He is currently joining the Strategy and Innovation Department of Telecom Italia (Future Centre) addressing innovation activities on Software Defined Networks, Network Function Virtualization, Internet of Things and 5G. He is keeping a Blog on Softwarization (http://ieee-sdn.blogspot.it/).
“Softwarization” and the disappearing of Internet of Things
“Softwarization” is going to transform the Telecommunications infrastructure into a “continuum” of logical resources, extended from the end-Users’ terminals, through the Network, up to the Data Centers. In fact, “Softwarization” can be seen as a crossing point of key technological trajectories, such as: pervasive diffusion of ultra-broadband; IT HW performance increase (at lower and lower costs); growing availability of Open Source SW; more and more advanced terminals. Not only the border between the network and the Cloud will disappear, but also terminals, intelligent machines, smart things, robots, etc. will become like edge nodes capable of storing data locally and even executing network functionality and service components. Eventually this “continuum” will absorb also the Internet of Things, and it will become so embodied into reality to disappear. It will be a profound techno-economic transformation of Telecommunications and ICT ecosystems paving the way to the true Digital Society and Digital Economy.
