The Security Design of the AWS Nitro System - The Security Design of the AWS Nitro System
Publication date: February 15, 2024 (Document revisions) Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. The AWS Nitro System is the underlying platform for all modern EC2 instances. This whitepaper provides a detailed description of the security design

Linux PV on HVM
This document discusses using paravirtualized devices in Linux guests running on Xen in HVM (hardware virtual machine) mode. It offers the benefits of HVM like installing the same as native while also providing access to fast paravirtualized devices. Initial support added xenbus and grant table support while later enhancements added ballooning, spinlocks, and interrupt/MSI remapping. Benchmarks sh
