It is good to see Europe take an important leadership role in recognizing the critical contribution that commercial cloud providers can play in providing solutions for big science through their recent Helix Nebula -- the Science Cloud announcement. It is estimated that 1/3 of the science applications running on expensive HPC facilities could easily run on commercial clouds, freeing up these facilities to focus on true high computational problems. more»
The Department of Energy (DoE) recently came out with an excellent report, called the Magellan report, on the advantages and disadvantages of using commercial clouds versus in house High Performance Computers (HPC) for leading edge scientific research. The DoE probably supports the largest concentration of HPC facilities in the world. I agree with the report that for traditional applications such as computational chemistry, astrophysics, etc. will still need large HPC facilities. more»
Doug Madory reporting in Renesys Blog: "Packet latency is a big issue in Internet-based applications (i.e. the stuff in the cloud). In conducting analysis on Internet infrastructure over the years, we have seen many patterns of connectivity. One such pattern that can wreak havoc on latency is 'hair-pinning', a phenomenon where traffic takes an unnecessarily long physical path between two points on the Internet due to suboptimal routing. The increased distance results in increased latency, and the 'lag' or 'sluggishness' that users experience as a result can hinder latency-sensitive online applications whether they are financial trading applications or MS SharePoint." more»
From will they ever learn department, we are once again seeing attempts by incumbent carriers to skirt rules around network neutrality. They tried and failed with UBB. Now they are at it again with "speed boost" technologies. The two technologies at question are Verizon's "Turbo" service and Roger's "SpeedBoost". more»
There has been considerable discussion about the future of broadband in terms of infrastructure i.e. fiber, wireless, community owned etc. However, there has been little discussion, to borrow a phrase from Internet 2, on Net+ broadband services. It is in the Net+ services where I think R&E networks can play a critical in helping communities and small commercial ISPs deploy advanced services and applications that will provide new business models to underwrite the costs of next generation broadband. more»
There have been some interesting new developments in university Green Revolving Funds (GRF) that I believe could be a significant revenue opportunity for cloud suppliers and R&E networks. In this age of severe financial constraints and cutbacks for universities, new revenue models are needed to sustain advanced cyber-infrastructure in support of research and education. more»
It is great to see US and European governments undertake initiatives to promote the development of research into Big Data utilizing commercial clouds. Many cloud providers are offering free resources to support these initiatives. R&E networks will play a critical role in linking researchers to the commercial clouds and developing collaboration platforms and portals. more»
Google today launched a long-rumored "Drive" service to allow users store photos, videos, and other digital files in its massive data centers. Available immediately, first five gigabytes of storage per account of Google Drive is free and additional storage will be sold for prices starting at $2.49 per month for 25 gigabytes. more»
