A Blog of the ZHAW Zurich University of Applied Sciences
An academic entity – more concretely, a research laboratory – resembles a stateful function: It receives input and generates output based on both the input and on previously generated knowledge and results. The input is typically a mix of fancy ideas, industry necessities, as well as funding and equipment. The output encompasses publications, software and […]
Our flagship open-source framework for cloud billing – Cyclops has matured to version 2.0 today. Over the past several months, Cyclops team at ICCLab have gathered community feedbacks, worked systematically updating and re-updating the framework core architecture to make the whole work-flow of billing of cloud services clean and seamless. The core components in principle […]
The Service Engineering (SE, blog.zhaw.ch/icclab) group at the Zurich University of Applied Sciences (ZHAW) / Institute of Applied Information Technology (InIT) in Switzerland is seeking applications for a full-time position at its Winterthur facility. The successful candidate will work in the Service Prototyping Lab (SPLab) and will contribute to the research initiative on cloud robotics, […]
Up to now, we have published several blog posts focusing on the live migration performance in our experimental Openstack deployment – performance analysis of post-copy live migration in Openstack and an analysis of the performance of live migration in Openstack. While we analyzed the live migration behaviour using different live migration algorithms (read our previous blog posts regarding pre-copy […]
It is well recognized that GPUs can greatly outperform standard CPUs for certain types of work – typically those which can be decomposed into many basic computations which can be parallelized; matrix operations are the classical example. However, GPUs have evolved primarily in the context of the quite independent video subsystem and even there, the […]
We are proud to announce that the ICCLab has released Hurtle! Hurtle is a result of the ICCLab’s Cloud Orchestration Initiative. What is hurtle? With Hurtle, you automate the life-cycle management of any number of service instances in the cloud, from deployment of resources all the way to configuration and runtime management (e.g., scaling) of each instance. […]
Today the ICCLab introduces a new way on how to interact with your notes. http://icclab.github.io/powdernote/ What is powdernote? Powdernote is a note-taking, cloud-based application for the terminal. Why powdernote? Because we never leave the terminal, not even to read our notes or create new ones. This tool is for busy engineers, developers, power users, devops, … […]
There are many different technologies which can increase availability of a cloud infrastructure. In our newest Techcouting paper we evaluate several HA technologies in order to define a HA architecture for an OpenStack deployment which is part of the XiFi project. HA technologies can be grouped in the following classes: Resource monitors that check if […]
Overview Cloud computing means: On-demand self service Virtualization Elastic resource provisioning Cloud computing service is comparable to public utility services like gas, telephone or water supply. Economical value of cloud computing service is determined by reliability, availability and maintainability (RAM) characteristics. Availability impacts the value of cloud computing as it is perceived by end users. […]
Joyent recently open sourced the IaaS Platform SmartDataCenter and the Object Storage Manta, the software they use for their own service offerings. So, what’s all the buzz about? Why should you be excited? Why is it even worth talking (or in this case, writing) about SDC when we have OpenStack? In this blog post I will cover […]
