In 2010, however, nearly none of it existed: the CNCF wasn’t formed until 2015! The abstractions that Eureka provides for this are Virtual IPs (VIPs) for insecure communication, and Secure VIPs (SVIPs) for secure. There is a downside to fetching this data on-demand: this adds latency to the first request to a cluster.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object).
