Keepalived for Linux – Keepalived is a routing software written in C. The main goal of this project is to provide simple and robust facilities for loadbalancing and high-availability to Linux system and Linux based infrastructures. Loadbalancing framework relies on well-known and widely used Linux Virtual Server (IPVS) kernel module providing Layer4 loadbalancing. Keepalived implements a set of checkers to dynamically and adaptively maintain and manage loadbalanced server pool according their health. On the other hand high-availability is achieved by VRRP protocol. VRRP is a fundamental brick for router failover. In addition, Keepalived implements a set of hooks to the VRRP finite state machine providing low-level and high-speed protocol interactions. Keepalived frameworks can be used independently or all together to provide resilient infrastructures.
The BIRD Internet Routing Daemon Project – BIRD is an Internet Routing Daemon designed to avoid all of these shortcomings, to support all the routing technology used in the today's Internet or planned to be used in near future and to have a clean extensible architecture allowing new routing protocols to be incorporated easily. Among other features, BIRD supports: * both IPv4 and IPv6 protocols * multiple routing tables * the Border Gateway Protocol (BGPv4) * the Routing Information Protocol (RIPv2) * the Open Shortest Path First protocol (OSPFv2, OSPFv3) * the Router Advertisements for IPv6 hosts a virtual protocol for exchange of routes between different routing tables on a single host a command-line interface allowing on-line control and inspection of status of the daemon soft reconfiguration[...]
How to make MaxScale High Available with Corosync/Pacemaker | MariaDB – MaxScale, an open-source database-centric router for MySQL and MariaDB makes High Availability possible by hiding the complexity of backends and masking failures. MaxScale itself however is a single application running in a Linux box between the client application and the databases – so how do we make MaxScale High Available? This blog post shows how to quickly setup a Pacemaker/Corosync environment and configure MaxScale as a managed cluster resource.

okvm – Open source KVM over IP technology – The okvm project team in 2005 developed an open source okvm KVM Development Kit – so engineers could cost effectively roll their own integrated KVM over IP control appliances. These okvm KVM Development kits included: one okvm PCI KVM Adapter card the okvm KVM over IP software source code the source information needed to manufacture the okvm PCI KVM Adapter card (circuit diagrams, BOM,PCD layout etc) A number of the KVM PCI cards were produced – sponsored by Opengear. However this project did not find traction in the developer community. So kits are no longer available and development in this branch of the project has stopped. Also Opengear now sells a proprietary KVM over IP solution!

Riemann – A network monitoring system – Riemann aggregates events from your servers and applications with a powerful stream processing language. Send an email for every exception raised by your code. Track the latency distribution of your web app. See the top processes on any host, by memory and CPU. Combine statistics from every Riak node in your cluster and forward to Graphite. Send alerts when a key process fails to check in. Know how many users signed up right this second. Riemann provides low-latency, transient shared state for systems with many moving parts.

Facette: Time series data visualization and graphing software – Facette is a time series data (called metrics) visualization software, it doesn’t collect nor store these data on its own. Through providers, it inventories other collect/storage tools’ local metrics, and queries those remote storage resources when the user requests time series data to be displayed on a graph.
