Highly Available KeyValue Store 1 Dennis Kafura CS5204 Operating Systems Dennis Kafura CS5204 Operating Systems Context Core ecommerce services need scalable and reliable storage for massive amounts of data. The new model produced since 2011 is similar to the SONdelux regarding build and looks Flange and bearing distance of the nondisc version however are much larger so that it is the big brother of SONdelux not only electrically but also mechanically R Amazon’s Highly Available Key-Value Store. Presented By. Roni Hyam. Ami Desai. Introduction. Dynamo is a highly available and scalable key-value storage system adapted for a number of core services in Amazon’s e-commerce platform..
