"Here You can find ready to download virtual machines with preinstalled different Open Source Unix and Linux operating systems. Each virtual machine on this website has been prepared using VMware Player technology."

"VirtualBoxImages.com is the worlds leading source for pre-installed virtualbox virtual computers. No other single source provides more virtual computer choices. This is the mother lode of VirtualBox virtualization software. VDI images of pre-installed "Open Source" Operating System distros. Pre-installed virtualbox images ready for you to explore and play with. VirtualBox runs on SunOS, OpenSolaris, Mac OS X, Windows, OS/2 and Linux. It's a computer inside your computer."

SoftNAS™ is business-class network attached storage (NAS) delivered as software as a service.  The NAS software virtual appliance runs within your cloud computing environment (e.g., Amazon EC2) or local virtual server environment (e.g., VMware vSphere) and manages the available raw disk storage, providing enterprise-grade storage capabilities. SoftNAS leverages a number of open source technologies, including ZFS on Linux.  ZFS on Linux is a port of the popular ZFS filesystem originally produced by Sun Microsystems and released with OpenSolaris.  SoftNAS builds on the robust, solid foundation of ZFS and its powerful, extensible Linux foundation.

"Welcome to the VirtualBox® Images project website. This project provides virtual machines for Sun XVM VirtualBox® sporting several free and/or open-source operating systems, such as GNU/Linux or Free/Net/OpenBSD for testing, security and/or entertainment purposes."

"Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere. Docker containers can encapsulate any payload, and will run consistently on and between virtually any server. The same container that a developer builds and tests on a laptop will run at scale, in production, on VMs, bare-metal servers, OpenStack clusters, public instances, or combinations of the above."

The VMKit project is a framework for building virtual machines. It uses LLVM for compiling and optimizing high-level languages to machine code, and MMTk to manage memory. J3 is an implementation of a JVM with VMKit.

"In 2010 we led the seed round for Docker (formerly known as dotCloud) for one simple reason: devops means that the way applications are packaged, deployed, and run is fundamentally changing (though Docker's business model has evolved since its early days as a PaaS vendor, the fundamental premise is the same).  Rather than requiring custom configurations and painstaking management, Docker "containerizes" applications components such that every container is lightweight and behaves consistently.  Applications and their underlying components can be programmatically deployed, managed and moved on ever-changing cloud infrastructure without a hint of operating system or hardware configuration.  In a pre-Docker world, companies with tremendous and evolving application demands looked to virtualization as a way of abstracting their infrastructure, but paid a tax in dollars and performance for doing so. In the future we think of Docker will take the mantle as the VMware of the devops world, with containers as the ultimate devops platform."

This document provides information on typical command-line options and environment variables that can affect the performance characteristics of the Java HotSpot Virtual Machine.

Highly efficient file backup system based on the git packfile format. Capable of doing *fast* incremental backups of virtual machine images.

"Everything at Google, from Search to Gmail, is packaged and run in a Linux container," explained Eric Brewer, vice president of infrastructure at the Internet search giant, in announcing the open sourcing of Kubernetes. "Each week we launch more than 2 billion container instances across our global data centers, and the power of containers has enabled both more reliable services and higher, more-efficient scalability."

"Weave creates a virtual network that connects Docker containers deployed across multiple hosts." Muchos buenos features para armar redes dinámicas de contenedores en distintos hosts/redes físicos/as.

An Updated Performance Comparison of Virtual Machines and Linux Containers

Muy buena data!

Google publicó el primer preview de su nuevo lenguaje. Soporta 2 ambientes de ejecución: una nueva virtual machine y compilado a javascript. La VM soporta startups muy rápidos leyendo el estado del sistema desde archivos de imagen estilo smalltalk. El lenguaje es OO pero basado en interfaces, no clases (aunque tiene clases, todos los method dispatch se refieren a una interfaz). El tipado estático es 100% opcional, permite no poner tipos e incluso permite ejecutar código que no valide el typechecker (con errores). El modelo de ejecución es tipo erlang como procesos single-threaded aislados unos de otros (no pueden compartir nada) que solo se comunican pasando mensajes, éstos se llaman "Isolates".

"Vagrant project to spin up a cluster of 4 32-bit CentOS6.5 Linux virtual machines with Hadoop v2.6.0 and Spark v1.1.1"

"Spoon allows you to package applications and their dependencies into a lightweight, isolated virtual environment called a "container." Containerized applications can then be run on any Windows machine that has Spoon installed, no matter the underlying infrastructure. This eliminates installs, conflicts, breaks, and missing dependencies."

"Avian is a lightweight virtual machine and class library designed to provide a useful subset of Java's features, suitable for building self-contained applications."

"In October 2014, Databricks participated in the Sort Benchmark and set a new world record for sorting 100 terabytes (TB) of data, or 1 trillion 100-byte records. The team used Apache Spark on 207 EC2 virtual machines and sorted 100 TB of data in 23 minutes."

"In an indication of how rapidly the containerized technology ecosystem is metastasizing, SocketPlane.io - a startup venture founded just last October with the goal of building a controller-less software-defined network model for Docker environments - is being acquired by Docker, Inc., the two organizations jointly announced Wednesday morning. SocketPlane creates a networking abstraction for Docker containers at the socket layer. It connects containers without the need for a network controller, either physical or virtual. Put another way, it facilitates a software-defined network by letting the containers be the network."
