VisualOps is a Platform as a Service (PaaS) that aims to simplify operations tasks like deploying code, configuring infrastructure, scaling, and handling failures. It provides an IDE interface for visually designing infrastructure as code using reusable components. The designs are rendered into recipes that agents on instances use to automate configuration via SaltStack. VisualOps handles dependencies and ensures environments always match their designs. It improves on other PaaS options by allowing more customization of architectures, integration of resources, and deploying associated environments together.
This document illustrates the general architecture and data flow of tgtd, the iSCSI target daemon. It shows how tgtd handles iSCSI requests from initiators and processes SCSI commands by communicating with low-level driver routines and backing storage devices like mmc, osd, and sbc. Management tasks like login, logout, and error handling are also depicted.
Fedora Atomic is a minimal OS designed specifically for running containers. It uses rpm-ostree to provide atomic updates that allow the OS filesystem to be updated immutably. Key components include Docker for containers, Kubernetes for orchestration, and Cockpit for a web-based management interface. The demo shows how to use cloud-init to customize Atomic images, install and use Cockpit to manage containers, and understand the "atomic" command wrapper.
