Notes about Cutting-Edge Technologies and Everything

Cloud Computing as a term is not very well defined but is often associated with multi-tenant datacentres, commodity computers connected with an IP network, elastic/on-demand resource allocation, and metered billing. Antonio Regalado, a senior editor for biomedicine for MIT Technology Review decided to find out where it all began, https://www.technologyreview.com/s/425970/who-coined-cloud-computing/

Rather than using configured constant timeouts, systems can continually measure response times and their variability, and automatically adjust timeouts according to the observed response time distribution. This can be done with a Phi Accrual failure detector, which is used by Cassandra and Akka. http://ternarysearch.blogspot.ca/2013/08/phi-accrual-failure-detector.html
