Containerized applications are becoming increasingly popular, but unfortunately, current containerdeployment methods are very slow. We develop a new container benchmark, HelloBench, to evaluate the startup times of 57 different containerized applications. We use HelloBench to analyze workloads in detail, studying the block I/O patterns exhibited during startup and compressibility of container i...

BACKGROUND Semantic Web technologies have been widely applied in the life sciences, for example by data providers such as OpenLifeData and through web services frameworks such as SADI. The recently reported OpenLifeData2SADI project offers access to the vast OpenLifeData data store through SADI services. FINDINGS This article describes how to merge data retrieved from OpenLifeData2SADI with o...

Summary Short reads sequencing technology has been used for more than a decade now. However, the analysis of RNAseq and ChIPseq data is still computational demanding and the simple access to raw data does not guarantee results reproducibility between laboratories. To address these two aspects, we developed SeqBox, a cheap, efficient and reproducible RNAseq/ChIPseq hardware/software solution bas...

Abstract Containerization technology offers an appealing alternative for encapsulating and operating applications (and all their dependencies) without being constrained by the performance penalties of using Virtual Machines and, as a result, has got interest High-Performance Computing (HPC) community to obtain fast, customized, portable, flexible, reproducible deployments workloads. Previous wo...

Several fields of science have traditionally demanded large-scale workflows support, which requires thousands of CPU cores or more. Since users’ demands for software packages and configuration is the difference, an approach to making available in real time a service environment desired by users without significant challenges for administrators is necessary. In this paper, we present a container...

For a long time, the term virtualization implied talking about hypervisor-based virtualization. However, in the past few years container-based virtualization got mature and especially Docker gained a lot of attention. Hypervisor-based virtualization provides strong isolation of a complete operating system whereas container-based virtualization strives to isolate processes from other processes a...

Linux containers have recently gained more popularity as an operating system level virtualization approach for running multiple isolated OS distros on a control host or deploying large scale microservicebased applications in the cloud environment. The wide adoption of containers as an application deployment platform also attracts attackers’ attention. Since the system calls are the entry points...

We describe the Rocker project, which provides a widely-used suite of Docker images with customized R environments for particular tasks. We discuss how this suite is organized, and how these tools can increase portability, scaling, reproducibility, and convenience of R users and developers.

We introduce an open-source, scalable, and distributed architecture, called Megalos, that supports the implementation of virtual network scenarios consisting devices (VDs) where each VD may have several Layer 2 interfaces assigned to LANs. rely on Docker containers realize vendor-independent VDs we leverage Kubernetes for management nodes a cluster. Our architecture does not require platform-sp...
