+ - Updating Amdahl's Law->

Submitted by Random Feature
Random Feature (84958) writes "Can distributed application performance be distilled down to a simple formula? Joe Weinman of HP and Cloudonomics fame has a new paper out called "As Time Goes By: The Law of Cloud Response Time" that provides an update to Amdahl's law as it relates to web application performance. This paper is full of tasty mathematical formula meat, so chew thoroughly."

+ - Claim: Cloud Computing is NP-Complete-> 1

Submitted by Random Feature
Random Feature (84958) writes "If clouds are built from NP-complete algorithms then clouds are themselves NP-complete. Which means Brewer's CAP theorem will always be true and you can never reach 100% availability or consistency and we should just stop trying. Side effect — wouldn't that also mean the Internet is NP-complete as it relies upon networking algorithms almost all of which are NP-complete problems?"

Submitted by Random Feature
Random Feature (84958) writes "In response to Build an Open Source SSL Accelerator, in which o3 magazine detailed how to build a solution comparable to an F5 BIG-IP 6900 on the cheap, F5 Fires Back claiming it's not as cheap as it appears and pointing out the potential performance implications of a "cobbled together set of components designed to mimic similar functionality." The discussion on the performance of the Open Source solution based on Opteron RSA operation processing capabilities brings into question the validity of the "more SSL TPS for cheaper" argument presented by o3."

+ - Load Testing as a Service: A Look at Load Impact (->

Submitted by Random Feature
Random Feature (84958) writes "Everything is becoming a service, including load testing. This is a review of Load Impact (Beta), a service that includes a free version for load testing web applications across the web. Dangerous? Maybe, but load testing applications using frameworks like Google AppEngine or hosted on AWS are hard to load test without some kind of tool and Load Impact may be one of them. And it's free. Who doesn't like free?"

Submitted by Random Feature
Random Feature (84958) writes "The Cloud Computing Interoperability Forum (CCIF) is currently discussing cloud portability specifications. It seems crazy to define a standard before we even know who owns what in the cloud because you can only port what you own. For example, if you created a security or acceleration policy for your cloud computing-based app, is the policy yours or the provider's? Who owns meta-data in the cloud?? True portability between clouds seems impossible depending on the answer."

Security

+ - Blaming the Victim?

Submitted by Random Feature
Random Feature (84958) writes "This article at InformationWeek talks about the "pain" of being in IT. Is it perhaps because we blame ourselves for all IT woes, especially those that are security related? This blogger thinks we should stop "blaming the victim" when security breaches occur. Are we too hard on ourselves? Are we doing enough? Is security really futile in the end? Is Bruce Schneier right and it's all our fault for not being security-minded enough?"
