- 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.

- Digital Attack Map – Digital Attack Map is a live data visualization of DDoS attacks around the globe, built through a collaboration between Google Ideas and Arbor Networks. The tool surfaces anonymous attack traffic data to let users explore historic trends and find reports of outages happening on a given day. [ via https://delicious.com/farmando ]
- uProxy – What is uProxy? uProxy is a browser extension that lets users share alternative more secure routes to the Internet. It's like a personalised VPN service that you set up for yourself and your friends. uProxy helps users protect each other from third parties who may try to watch, block, or redirect users’ Internet connections.

- Clustering with JBoss mod_cluster – jboss cluster – JBoss application server tutorials – Mod cluster is an http based load balancer which greatly simplify the setup of an http cluster. It ships as a set of modules which need to be installed on the httpd server and a Service Archive Library (.sar) which needs to be deployed on JBoss AS (It is built-in in JBoss AS 6/7). Compared with the former mod_jk, the new mod_cluster has the great advantage to accept a dynamic configuration of httpd workers. This can be done through an advertise mechanism where all httpd workers communicate lifecycle events (like startup or shutdown) thus leveraging dynamic configuration of nodes.
- How to configure mod_cluster with JBoss ? « JBoss – Like mod_jk, mod_cluster is also a httpd based load balancer which uses a communication channel to forward requests from the httpd to one of a set of application server nodes. So the question comes Why mod_cluster ? To answer this question we will let you know few advantages of mod_cluster over mod_jk and other httpd-based load balancers.
