Free enterprise architecture definition software for linux

An open Quality of Service Architecture is an open architecture for the provisioning of Quality of Service related functionality into the Linux kernel.
The project features a flexible, portable and lightweight software architecture for supporting QoS related services on the top of a general-purpose operating system as Linux. The architecture is well founded on formal scheduling analysis and control theoretical results.
At the core of the software there is an adaptive Resource Reservation layer that is capable of dynamically adapting the CPU allocation for QoS aware applications based on its run-time requirements.
As it is highlighted by the AQuoSA architecture, the project is mainly composed of two components:
- the QoS Res module, for which you can browse online the kernel, application and internal APIs
- the QoS Mgr module, for which you can browse online the kernel, application and internal APIs
Enhancements:
- Some bug fixed

Af-Arch is being developed to give GNU/Linux a new middle-ware for building enterprise managing applications, typically database oriented.
Af-Arch is a complete set of libraries and tools which allows to develop distribuited system especially designed to face problems about bussiness applications.
Actually, Af-Arch is really robust and stable, having systems installed on many environments. Af-Arch, at this moment, runs on GNU/Linux and Microsoft Windows.
AF Architectures license schema is based on GPL and LGPL, allowing you to develop not only open source applications but also comercial applications without any royalty or fee.
Af-Arch is a strongly documented project, which is proved to work. Af-Arch keeps on evolving and growing its feature list allways keeping in mind productivity.
Enhancements:
- A new major stable release have come with many interesting features, library dependencies news, new API to make life easy and a bunch of work to make the library to be memory efficient.
- Af-Arch no longer depends on GDA library (http://www.gnome-db.org). Now AfGs, server side support for Af-Arch, includes built-in database abstraction support, implemented to fit better with the Af-Arch framework. For more details check the "libafgs" log below.
- Af-Arch platform now support three new return types: AfDalNodeData, AfDalStringData and AfDalDecimalData, which allows services to return a module node, a plain string and a decimal value as a result for the invocation.
- Af-Arch now support a new formal parameter service AfDalSetOf which implements set of items to be sent while the service is invoked.
- af-gen tool now support defining string literals that are separated by "+" sign, making it easy to write long SQL sentences.
- af-gen tool now allow to generate type definitions that could extend, making it possible to create a class hierarchy for types to be returned by services.
- libafdal core library now implements a better error reporting mechanism which allows to receive all errors generated while performing invocation at the reply process code.
- New reserved services have been added: element_peek_reference which allows to get the node associated to a module which is relationed through the 0..1 link.

Growler is a C++-based distributed object and event architecture. The software is written in C++, and supports serialization of C++ objects as part of its Remote Method Invocation, Event Channels, and in its Interface Definition Language.

Its primary application has been in support of interactive, distributed and collaborative visualization, computational steering, and concurrent visualization.

Adaptive Quality of Service Architecture (AQuoSA) is an open architecture for the provisioning of adaptive Quality of Service functionality into the Linux kernel. The project features a flexible, portable, lightweight and open architecture for supporting soft real-time applications with facilities related to timing guarantees and QoS, on the top of a general-purpose operating system as Linux.
At the core of the architecture there is an adaptive resource reservation layer that is capable of dynamically adapting the CPU allocation for QoS aware applications based on their run-time requirements.
Timing guarantees are provided through an in-kernel reservation based process scheduler, whose services are exposed to applications through a well-designed API.
A supervisor performs admission control, so that admitting into the system new applications with timing guarantees does not affect the timing guarantees of already admitted applications. Also, it takes care of guaranteeing appropriate security policies in the assignment of timing guarantees to users and user groups, as configured by the system administrator.
A feedback-based QoS control layer may be optionally used by applications who want to keep their timing guarantees by using a CPU allocation that is continuously adapted according to their actual needs. This leaverages the programmer, within certain limits, to hard-code any particular reservation amount within the application, because the best allocation is found out automatically at run-time. Also, this enhances the possibilities for the system to host additional QoS controlled applications. The available control algorithms are well founded on formal scheduling models and control theoretical results.
Enhancements:
- This release introduces a couple of flags useful when creating servers. If QOS_F_PERSISTENT is enabled, a server is allowed to exist beyond detach of the last task. If QOS_F_SOFT is enabled, a server tasks are scheduled by the Linux default scheduler/policy, when outside of the server reservation.
- Also, various stability issues in destroying servers have been fixed, also thanks to a new release of the generic scheduler patch for the Linux kernel (gs-2.2).

Enterprise File Exchange (EFX) slots in where email file attachment limits stop your users from sending those important files to a contact.

In the EFX world, the user visits the EFX site, uploads the file, enters the receivers email address and lets the system notify the receiver that theres a file waiting for them, via a simple email message.

Senders need to sign up, and the EFX system only allows transfers between internal users (those with addresses in an approved list) and external users, never external to external.

It is written in Python, using the Pylons framework.

This project is licensed under the GNU GPL version 3.

Black Orion Network is an update and system management platform for among others Black Orions redhat-compatible Enterprise Linux Distributions. Black Orion Enterprise Linux software distributions are offered to you by the open source community as free software.

A program is free software if users are free to redistribute copies, either with or without modifications, either gratis or charging a fee for distribution, to anyone anywhere. Being free to do these things means (among other things) that you do not have to ask or pay for permission. Please feel free to make and redistribute as many copies of Black Orion Enterprise Linux as you like.

How It Works:

1. Obtain Black Orion Enterprise Linux

Obtain one of Black Orions redhat-compatible Enterprise Linux Distributions from the downloads section.

2. Burn cd images

Burn the downloaded iso images on to a cd.

3. Register yourself as a Black Orion Network Member

Register yourself as a member in the Black Orion Network section.

4. Install Black Orion on a computer

Read the manuals for the various installation options. The system can also be installed as a rhel4 virtual machine.

5. Connect your system to the Black Orion Network

Connect your system to the Black Orion Network with the up2date client installed on your system. You can find up2date by right-clicking the Black Orion Network Alert Icon on your desktop. Connect your system with your member name and password (see 3).

DSSH was written as a direct replacement for OpenSSH client for our use. The project adds SSH over SSH tuneling capabilities (for example to log in to network which is hidden by firewall), scripting support (using Groovy), advanced agent (which allows storing of passwords) and "su -" interactive logging for machines, which have disabled direct root login.

All of this was done to enable automated scripting and logging to lots of machines based on few simple rules.

It uses Ganymed SSH library (slightly patched). I tried to contribute my changes back to Ganymed-SSH authors and if I succeed, I will probably try to stick with official Ganymed-SSH distribution.
