The Linux-HA (High-Availability Linux) project provides a high-availability (clustering) solution for Linux, FreeBSD, OpenBSD, Solaris and Mac OS X which promotes reliability, availability, and serviceability (RAS).
The project’s main software product is Heartbeat, a GPL-licensed portable cluster management program for high-availability clustering. Its most important features are:

no fixed maximum number of nodes - Heartbeat can be used to build large clusters as well as very simple ones
resource monitoring: resources can be automatically restarted or moved to another node on failure
fencing mechanism to remove failed nodes from the cluster
sophisticated policy-based resource management, …

High availability is a system design protocol and associated implementation that ensures a certain absolute degree of operational continuity during a given measurement period.
Availability refers to the ability of the user community to access the system, whether to submit new work, update or alter existing work, or collect the results of previous work. If a user cannot access the system, it is said to be unavailable. Generally, the term downtime is used to refer to periods when a system is unavailable.
Planned and unplanned downtime
A distinction needs to be made between …

QNX (pronounced either Q-N-X or Q-nix) is a commercial POSIX-compliant Unix-like real-time operating system, aimed primarily at the embedded systems market. As of September 12 2007, the source of the QNX kernel has been released for non-commercial use.

Description
As a microkernel-based OS, QNX is based on the idea of running most of the OS in the form of a number of small tasks, known as servers. This differs from the more traditional monolithic kernel, in which the operating system is a single very large program composed of a huge number of …

Load balancing is the even distribution of computer processing and communication activities so that a server is not overwhelmed. Load balancing is especially important for networks where it is difficult to predict the number of requests that will be issued to a server.
Busy Web sites typically employ two or more Web servers in a load-balancing scheme. If one server starts to get swamped, requests are forwarded to another server with more capacity. Load balancing is therefore a service that is employed on more sophisticated site deployments.
Most service providers that offer …

Virtual Private Networks form a major part of many organizations’ network infrastructure. They are often used as a vehicle to serve sensitive information to remote offices and workers. Typically VPN’s are created point-to-point making it difficult to add any resilience or more bandwidth. Introducing our products to this infrastructure makes this possible, whether you are implementing new or expanding existing VPN infrastructure.
Drawbacks of existing technology:
Single Point of Failure
Traditional VPN’s both client and site-to-site are based upon a single Internet link. Should this link fail, organizations invariably have no fall-back plan, …
