Research on Critical Data-Intensive Distributed Systems

More and more important applications are relying increasingly on the processing of large volumes of data. These include, for instance, IoT applications for monitoring of traffic, transport systems, water networks, and other critical infrastructures within cities. Other applications monitor the vital parameters of remote patients in distributed telemedicine setups and current environment conditions such as seismic activities using large-scale distributed sensor networks. Moreover, businesses and the sciences have to deal with increasingly large amounts of real-time and historic data, be it to quickly detect fraudulent behavior in millions of payment transactions or comparing terabytes of human genomic data to accurately identify genetic disorders.

For many of these applications, there are clearly defined expectations for the required quality of service in terms of end-to-end latencies, throughput, scalability, availability, as well as the reliability of ingested and produced data. At the same time, distributed data processing applications are being deployed to more heterogeneous and dynamically changing environments.

As a result, running large-scale distributed applications is often a very difficult task, especially when given critical targets for performance and dependability. In fact, we argue that – while high-level programming abstractions and comprehensive processing frameworks have made it easier to develop data-intensive applications – operating critical data-intensive systems and applications has become more difficult over the last decade. And there is abundant evidence of low resource utilization, limited energy-efficiency, and severe failures with infrastructures, systems, and applications deployed in practice, backing up this claim.

Addressing these problems, we develop methods, systems, and tools to make the implementation, testing, and operation of efficient and dependable data-intensive applications easier. Towards this goal, we work on resource management and fault tolerance in distributed heterogeneous computing environments from small IoT devices to large-scale clusters of computers, aiming to create systems that automatically adapt to specific workloads, environments, and requirements.

Our Research Methodology

We mostly do empirical systems research: we evaluate new ideas by implementing them prototypically in context of relevant open-source systems (such as Apache Flink, Hadoop YARN, Kubernetes, and FreeRTOS) and then conduct experiments on actual hardware, with exemplary applications, and real-world datasets. For this, we have access to state-of-the-art infrastructures, including a 200-nodes commodity cluster, our faculty's HPC cluster, private clouds, as well as IoT devices and sensors. That is, as far as possible, we empirically evaluate new ideas in their actual environments, making use of emulations and simulations only to be able to investigate more and more large-scale scenarios than physically feasible for us.

At the same time, we also work on practical applications to experience relevant problems ourselves and, thereby, uncover opportunities for well motivated and impactful research.

Projects

We have upcoming, active, and completed research projects in this area of research.

Upcoming


BIFOLD

The Berlin Institute for the Foundations of Learning and Data (BIFOLD) will conduct research on the foundations of AI. This includes investigating methods for the management and processing of large, distributed data as well as for machine learning. Within the project, we will develop and evaluate new methods for the adaptive usage of heterogeneous, distributed resources for the efficient processing of sensor data streams. The goal is to capture the key characteristics of constantly changing computing environments and have distributed processing systems adapt appropriately to major changes, so the required quality of service can be provided as far as possible and even in case of failures.

ide3a

The new [i]nternational [a]lliance for [d]igital [e]-learning, [e]-mobility and [e]-research in [a]cademia (ide3a) is a new project funded by DAAD that will conduct teaching and research on the digitalization of critical infrastructures like water networks, energy grids, sensor networks, and other interconnected urban systems. In the project we will support new courses with new e-learning methods and usable simulation tools. The TU Berlin is at the center of this effort but the project network also includes five major European partners: the Norwegian University of Science and Technology, the Dublin City University, the Cracow University of Technology, Politecnico di Milano, and the Hasso-Plattner-Institute, supporting the mobility of students of these partners across Europe.
