Available: IT Sourcing Textbook for the Classroom

Just before the summer I and two other fellow editors published a book about IT sourcing that is also suitable for the classroom. By presenting perspectives on IT sourcing from 21 different contributors, we as editors hope to enable and inspire readers to make better-informed IT Sourcing decisions. We received some nice endorsements: “What most […]

Cloud Computing Energy Usage: don’t forget the Last Mile

Access networks, not data centres, are the biggest threat to the sustainability of cloud services. This is the conclusion of a research conducted by the University of Melbourne. The datacenter industry is very much focussed on the energy efficiency inside the datacenter and the benefits of economy of scale by centralizing computer power and data […]

Datacenters need another perspective on security

As stated by Intel “Changing demands for bandwidth, processing power, energy efficiency and storage – brought on by such trends as cloud computing, big data, increased services and more mobile computing devices hitting the network – are driving the need for new architectures in the data center.” Therefore we see that the datacenter world is […]

Datacenters: The Need For A Monitoring Framework

For a proper usage and collaboration between BMS, DCIM, CMDB, etc. the usage of an architectural framework is recommended. CONTEXT A datacenter is basically a value stack. A supply chain of stack elements where each element is a service component (People, Process and Technology that adds up to an  service). For each element in the […]

Datacenters: blending BIM, DCIM, CMDB, etc.

How to manage the life cycle of a datacenter with a rapidly changing environment and where so many stakeholders are involved? Context A datacenter is a very special place where three different worlds and groups of people meet – there is the facility group whose focus is on the building, there is the IT infrastructure group […]

Green cloud computing and the burden of the network (follow up)

How does cloud computing energy consumption compare with conventional computing? A new research report can help to improve strategic decision making on sustainability and cloud computing. Most studies of energy consumption in cloud computing have focused only on the energy consumed in the data center. Although research showed that the energy consumption of data networks is […]

Data centers, Emergency Power and Crowdsourcing

Data Centers are helping to deliver emergency power to the power grid with the use of a crowdsourcing business model. A very specific element of an electrical power grid is that there is no storage. Therefore demand and supply must be the same, in equilibrium, else there is the risk that this power grid shuts […]

Cloud Computing Contracts and geolocation

As very well explained in the paper on negotiating cloud contracts by Stanford Technology Law Review (see also the blog Cloud Computing Contracts) cloud computing users can “have regulatory or other legal obligations and may need to demonstrate compliance to regulators”. Data location and data and data transfers are one of the most important data protection […]

Online library Green ICT practices available

In the context of a collaboration project between the VU University Amsterdam (Software and Services Research Group) and SURFNet, the VU University Amsterdam developed an on-line library for Green ICT practices. It currently contains 258 practices elicited from both industrial practice and academic publications. As stated by the project team “In spite of the investments […]
