The ongoing digitalization of the world, estimated to reach a yearly data generation of 200 Zettabytes by 2025, is putting increasing pressure on system developers to provide systems capable of scaling with future needs. Of particular importance are the data storage systems, providing the means of storing and retrieving the vast amounts of data....

Graphs are versatile enough to model many problems, and we see them used for<br/>solving a large spectrum of challenges in various disciplines. As the size of graph<br/>data grew over the years, to satisfy the requirement to process large data sets on<br/>time, distributed graph-processing systems were implemented.<br/>However, these systems...

Cloud datacenters underpin our increasingly digital society, serving stakeholders across industry, government, and academia. These stakeholders have come to expect reliable operation and high quality of service, yet demand low cost, high scalability, and corporate (environmental) responsibility. Datacenter operators are confronted frequently...

Datacenter infrastructure has become vital for stakeholders across industry, academia and government. To operate efficiently, datacenter operators rely on a variety of complex scheduling techniques, to distribute user workloads across resources. In this work, we leverage a reference architecture for datacenter scheduling to design and implement...

Complex workflows that process sensor data are useful for industrial infrastructure management and diagnosis. Although running such workflows in clouds promises reduces operational costs, there are still numerous scheduling challenges to overcome. Such complex workflows are dynamic, exhibit periodic patterns, and combine diverse task groupings...

Massively Multiplayer Online Games are played by millions of people from around the world who play together in large virtual environments. With sometimes even a million gamers playing the same game, the load on the virtual environments they play in needs to be distributed between servers to deal with this many players. Several techniques have...

Large enterprises and governments shift their long-running and critical operations to run in cloud environments. The on-demand business-critical workloads raise important challenges in datacenter operation, requiring efficient online scheduling of workloads with unprecendented dynamic behavior, yet under strict service level agreements (SLAs)....

Cloud computing has given users access to virtually infinite computing power. Cloud service providers operate data centers consisting of hundreds, sometimes thousands of interconnected machines. The machines dissipate heat that is undesirable because it may lead components to overheat. Air conditioners are used to cool the air and regulate the...

Nerdalize B.V. is an infrastructure-as-a-service (IaaS) cloud provider aiming to offer substantially lower prices than its competitors. In order to visualize its cost savings to customers and measure its own systems against competitors in a cloud market reigned by opaque pricing models, it would like to utilize an application benchmarker to give...

Virtualized multi-cluster, multi-datacenter datacenters are central to the digital economy, but require new techniques to address increasing scales, changing architectures, and dynamic workloads. Especially the introduction of new Business-Critical workloads that we characterize, create new resource management challenges. We propose a resource...

With the decrease in cost of storage and computation of public clouds, even small and medium enterprises (SMEs) are able to process large amounts of data. This causes businesses to increase the amounts of data they collect, to sizes that are difficult for traditional database management systems to handle. Distributed SQL Query Engines (DSQEs),...

Petabytes of data are processed daily by distributed applications built upon Hadoop and MongoDB. A significant fraction of these applications use cloud infrastructure to cope with this vast amount of data. Commercial clouds use virtualized environments, but most distributed applications are designed around the idea that they run on physical...

''Real-time services'' is a very challenging topic. Running analytics in real-time when there is an abstract network layer makes things even more complicated. The demand to analyze huge data-sets in real time or in the long term has been increasing over the past decade in many sectors including health-care, general science and various online...

In most businesses, email and collaboration services are essential to the performance of the company. Delivering a communication platform that scales well with the growth of the company, and provides the services anytime, anywhere, even in the event of failures is hard to achieve at low costs. Literature has proven that simplified email storage...

In this work, we propose the design of KOALA-C, a task scheduling system that can operate in integrated multi-cluster and multi-cloud environments based on two previous work: KOALA and SkyMark. We design and evaluate a number of task allocation and resource provisioning policies through both simulations and real-world experiments using KOALA-C.

For companies that deliver hardware services, the ability to scale dynamically has many advantages. In a special case, a company may have some computing resources available and desire to scale out when traffic peaks. A periodical budget may then be allocated, which needs to be used efficiently. This can be achieved through a combination of...
