Solution DBShadow Traditional High Availability solutions are failing to protect against logical system failures (human error, software error). With DBShadow in place you are protected against any incident, because your database is mirrored with a time delay – fully automated. In case of a logical or physical failure, you can simply switch to the mirror system and restore to the very latest consistent state of your database; and all of that within a couple of minutes. The time-delayed database mirror resides on a second server and can be anywhere in your Local Area Network (LAN) or Wide Area Network (WAN). The mirror database is deliberately delayed with a time-lag of for example four hours. However, all changes from the production database up to the current time are available on the mirror server, but just not in the database. In case of a crash, all remaining changes which should be applied are recovered within a very short timeframe and operation continues on the mirror server.

The SLB feature is a Cisco IOS-based solution that provides IP server load balancing. Using the IOS�SLB feature, the network administrator defines a virtual server that represents a group of real servers in a cluster of network servers known as a server farm. In this environment the clients are configured to connect to the IP address of the virtual server. The virtual server IP address is configured as a loopback address, or secondary IP address, on each of the real servers. When a client initiates a connection to the virtual server, the IOS�SLB function chooses a real server for the connection based on a configured load-balancing algorithm.

Smack is a library for communicating with XMPP servers to perform instant messaging and chat. Smack Key Advantages Extremely simple to use, yet powerful API. Sending a text message to a user can be accomplished in three lines of code: XMPPConnection connection = new XMPPConnection("jabber.org"); connection.login("mtucker", "password"); connection.createChat("jsmith@jivesoftware.com").sendMessage("Howdy!"); Doesn't force you to code at the packet level, as other libraries do. Smack provides intelligent higher level constructs such as the Chat and GroupChat classes, which let you program more efficiently. Does not require that you're familiar with the XMPP XML format, or even that you're familiar with XML. Provides easy machine to machine communication. Smack lets you set any number of properties on each message, including properties that are Java objects. Open Source under the Apache License, which means you can incorporate Smack into your commercial or non-commercial applications.

Quantum Framework™ (QF) is a reusable event-driven application framework for executing concurrent state machines specifically designed for real-time embedded (RTE) systems. QF applications consist of independent elements called active objects that collaborate to collectively deliver the intended functionality. Active objects in QF are encapsulated tasks (each embedding an event queue and a state machine) that communicate with one another asynchronously by sending and receiving events. Within an active object, events are processed sequentially in a run-to-completion (RTC) fashion, while QF encapsulates all the details of thread-safe event exchange and queuing. QF is designed to work with Quantum Event Processor (QEP) and a scheduler/RTOS of your choice.

Wow, really 'cheap' RAID storage solutions, where everything is redundant. And it uses Ultra ATA drives each on their own controller so you can cheaply expand with UATA drives for a fraction of the SCSI price. And the whole thing is easy to manage, cause its from Apple.
