About Ultra Monkey


Overview

Cluster Network Services
Ultra Monkey is a project to create load balanced and highly available network services. For example a cluster of web servers that appear as a single web server to end-users. The service may be for end-users across the world connected via the internet, or for enterprise users connected via an intranet.


Diagram: Sample Ultra Network
1. An end-user sends a packet to the virtual service
2. Ultra Monkey selects a server and forwards the packet
3. The server replies
4. Ultra Monkey forwards this reply back to the end-user

Flexible
Ultra Monkey makes use of the Linux operating system to provide a flexible solution that can be tailored to a wide range of needs. From small clusters of only two nodes to large systems serving thousands of connections per second.


Open Source Working with Your Network

Use Any Operating System
While the Ultra Monkey software itself runs on Linux, it is able to provide clustering for virtually any network services running on an operating system that can communicate using TCP or UDP. This means almost any operating system, including Windows™, Solaris™ and of course Linux itself.

Supports a Wide Range of Protocols
Ultra Monkey supports a wide range of protocols, with native health checks for: Web, Mail, FTP, News, LDAP and DNS. Other protocols can be suported using a non-native health check or by adding a custom health check.

Open Source
Ultra Monkey is open source. It makes use of software from various open source projects including The Linux Virtual Server and Heartbeat. Members of the Ultra Monkey project actively contribute to the open source projects whose software is used. Horms, the Ultra Monkey project lead, is one of the core members of the development teams for both Heartbeat and The Linux Virtual Server.
