DRBL (Diskless Remote Boot in Linux) is a solution to managing the deployment of the GNU/Linux operating system across many clients. Imagine the time required to install GNU/Linux on 40, 30, or even 10 client machines individually! DRBL allows for the configuration all of your client computers by installing just one server machine. DRBL provides a diskless or systemless environment for client machines. It works on Debian, Ubuntu, Mandriva, Red Hat, Fedora, CentOS and SuSE. DRBL uses distributed hardware resources and makes it possible for clients to fully access local hardware.

"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."

"Google Container Registry provides secure, private Docker image storage on Google Cloud Platform. While Docker provides a central registry to store public images, you may not want your images to be accessible to the world. In this case, you must use a private registry. The Google Container Registry runs on Google Cloud Platform, so can be relied upon for consistent uptime and security. The registry can be accessed through an HTTPS endpoint, so you can pull images from any machine, whether it's a Google Compute Engine instance or your own hardware."

"Internet Routing: It's a program (well, a daemon, as you are going to discover in a moment) which works as a dynamic router in an Internet type network (that is, in a network running either the IPv4 or the IPv6 protocol). Routers are devices which forward packets between interconnected networks in order to allow hosts not connected directly to the same local area network to communicate with each other. They also communicate with the other routers in the Internet to discover the topology of the network which allows them to find optimal (in terms of some metric) rules for forwarding of packets (which are called routing tables) and to adapt themselves to the changing conditions such as outages of network links, building of new connections and so on. Most of these routers are costly dedicated devices running obscure firmware which is hard to configure and not open to any changes (on the other hand, their special hardware design allows them to keep up with lots of high-speed network interfaces, better than general-purpose computer does). Fortunately, most operating systems of the UNIX family allow an ordinary computer to act as a router and forward packets belonging to the other hosts, but only according to a statically configured table."

"CoreOS is a Linux distribution that has been rearchitected to provide features needed to run modern clustered infrastructure stacks. The strategies and architectures that influence CoreOS allow companies like Google, Facebook and Twitter to run their services at scale with high resilience. We've implemented them correctly so you don't have to endure the slow, learn-as-you-go infrastructure building process. CoreOS can run on your existing hardware or on most cloud providers. Clustering works across platforms, making it easy to migrate parts of your gear over to CoreOS, or to switch cloud providers while running CoreOS."

"Envoy is a high performance C++ distributed proxy designed for single services and applications, as well as a communication bus and "universal data plane" designed for large microservice "service mesh" architectures. Built on the learnings of solutions such as NGINX, HAProxy, hardware load balancers, and cloud load balancers, Envoy runs alongside every application and abstracts the network by providing common features in a platform-agnostic manner. When all service traffic in an infrastructure flows via an Envoy mesh, it becomes easy to visualize problem areas via consistent observability, tune overall performance, and add substrate features in a single place."
