But OpenShift provides comprehensive multi-tenancy features, advanced security and monitoring, integrated storage, and CI/CD pipeline management right out of the box. Microservices architecture combines loosely-coupled functions to create high-performing applications. Speeds up development. The result? OpenShift 3.0

Virtualized in Hardware**: Hardware support for virtualization, and near bare-metal speeds. In this configuration, the AMI and boot is paravirt (PV), the kernel is making hypercalls instead of privileged instructions, and the system is using paravirt network and storage drivers. I'd expect between 0.1% The AMI and boot are now HVM.

This is the second generation EPYC server processor that uses the same Zen 2 architecture as the AMD Ryzen 3000 Series desktop processors. This is the first time any server vendor has even bothered to submit a TPC-E result for an AMD-based system since 2013. Higher memory speed and bandwidth. Higher memory density/capacity.

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. The cheapest (high volume) Androids perform like 2012/2013 iPhones, respectively. Recall that single-core performance most directly translates into speed on the web. The Moto G4 , for example.
