In this article we are looking how to implement Amazon S3 and Openstack Swift object storage based on Ceph Object Gateway (radosgw) service and how to run highly-available RabbitMQ messaging cluster – all turn-key with NodeFabric.
In this article we are looking how to implement Amazon S3 and Openstack Swift object storage based on Ceph Object Gateway (radosgw) service and how to run highly-available RabbitMQ messaging cluster – all turn-key with NodeFabric.
Deploying Highly Available Data Backend clusters in Amazon EC2 can be as simple as booting up 3 VM instances from NodeFabric AMI and enabling included MariaDB-Galera and Ceph data storage services.
NodeFabric Host Image is a modular system based on RedHat Enterprise Linux or CentOS operating system, integrating Docker containers, Consul Service Discovery and HAProxy LoadBalancers into vertical Solution Stack.
This article describes how you can set up safe salt-master execution path for production salt environments.
This article describes how you can set up your own RPM packaging repository and build RPM packages from upstream sources using git-buildpackage-rpm tool.

QEMU/KVM Linux Guests installation and management examples
Open Virtualization Format (OVF) is an open standard for packaging and distributing virtual appliances or more generally software to be run in virtual machines. The standard describes an “open, secure, portable, efficient and extensible format for the packaging and distribution of software to be run in virtual machines”. The OVF standard is not tied to any particular hypervisor or processor architecture. The unit of packaging and distribution is a so-called OVF Package which may contain one or more virtual systems each of which can be deployed to a virtual machine.
Following tables contain IDs of public OpenNode OS images that can be launched in Amazon EC2 Cloud.
This document is a quick step-by-step guide for first-time users to install and configure a basic OpenNode Cloud environment and create virtual machines.
In its current state virt-manager is not capable of fully managing OpenVZ linux containers - so it’s mainly a alternative GUI tool for doing KVM VM management with OpenNode OS - and not supporting all features that OpenNode OS may have. However we try to make virt-manager user experience as smooth as we can by pre-configuring libvirt for OpenNode related policies as much as possible.
OpenManage Server Administrator allows system administrators to manage individual servers in two ways: from an integrated, web-browser-based graphical-user-interface (GUI) and from a command-line interface (CLI) through the operating system. Server Administrator is designed for system administrators to manage systems locally and remotely on a network.
LVM snapshots have been around quite a while - but their copy-on-write (COW) implementation was flawed so that in case of multiple concurrently active snapshots perfomance degraded to non-acceptable levels. Until on one nice day it all got fixed in LVM2 2.02.90 release with LVM thin provisioning support.
OpenNode High Availability Cluster solutions are based on Red Hat Cluster Suite (RHCS) software. In this howto we describe one of the simplest ways to setup basic HA Cluster with shared block device (SAN or iSCSI) - resulting with simple 2-node active/passive failover setup which is ment to handle physical server failure.
