Open Source IT Infrastructure Deployment for Enterprises:

Sundyne possess expertise in a complete corporate deployment of Linux and open source applications to improve IT effectiveness and reduce total cost of ownership.

This offering provides full functionality and potential of Linux and open source software by using proven methodologies.

The software platform used is Linux, along with various open-source applications. This ensures a lower cost of ownership, along with the freedom to customize applications for the local needs. The various applications on Linux have become more than good enough in the past year, and can provide a desktop almost as good as Microsoft Windows.

For every key Windows application, there is an equivalent Linux application. Evolution from Ximian offers a mail client and personal information manager, creating an alternative for Outlook. Mozilla and derivatives like Phoenix and Galeon are web browsers which rival Internet Explorer. The OpenOffice suite of applications (Write, Calc and Impress) offers much of the functionality found in Microsoft Office (Word, Excel and PowerPoint). More importantly, it can read and write most MS-Office file formats. In addition, since it uses XML for native file storage, OpenOffice can be extended to build custom applications easily. OpenOffice also has a built-in utility to create PDF files. GAIM is a unified Instant Messaging application which can connect to the IM platforms of Yahoo, AOL, ICQ and MSN. Adobe Acrobat is available on Linux. Multimedia support is available in the form of mplayer. Gimp is an image-editing software. Java and Flash work on Linux. Open-source databases are also available, in the form of sqlite, MySQL and PostgreSQL.

The total cost of putting this suite of applications together: zero.

Our Thin client solution is combination of server-centric computing, diskless clients and open-source software which is the foundation for creating an affordable solution for the computing infrastructure

Features and Benefits of the above solution:  

• Provides a full suite of desktop applications, including email, browser, Office suite, instant messenger, calendar, contacts and more.  

• Reduces desktop software costs, by eliminating the need for expensive proprietary software.

• Eliminates virus risk, since Linux is the underlying environment.

• Offers a Windows-like graphical desktop, for ease of use.

• Reads and writes MS-Office file formats (DOC, XLS and PPT files).

• Eliminates desktop hardware upgrades, since all computing is on the server.

• Centralizes Administration, via the server through a front-end.

• Simplifies software upgrades, since only the server needs to be updated.

• Maintenance free as no possibility of corruption as the TC OS is read only

• Thin size of TC OS resulting in fast download and startup / booting.

• Supports multiple protocols(RDP for connecting to Windows NT/2000/XP Terminal server, X windows(Linux, Unix).

• Supports multiple connectivity Ethernet, Telnet, SSH, FTP support

• Multiple Client - Server session support. Multitasking or connecting to various servers simultaneously

Technical details of the solution:

We have devised a solution that should facilitate the use of diskless nodes to emulate terminal services provided by Linux and Windows. The list of the Applications that will be deployed and configured on the Linux server are as follows.

Server: Red Hat Enterprise Linux 3/4 AS powers Server with the following applications configured. 

• Office Applications mainly for

• Word processing

• Spread sheet

• Power point Presentation

• Acrobat Reader

• Internet Browser

• Email Client - TO connect to POP/IMAP compliant mail server

• XDMCP, RDP4.0 support.

The capabilities of the client are as follows:

Client: The above solution essentially address the following critical issues

1. The thin client nodes facilitate using local CDROM Drives and Floppy Drives.
2. As a part of configuration existing Windows user profiles are migrated to Linux.
3. Existing user data is ported to be able to be reused.
4. Provision for all fallback options for booting the node from various sources , viz Local boot(DOM),Remote boot(PXE) and Local Hard Disk boot if required .
5. The Remote boot solution is capable to allow the nodes to run in standalone mode in the event of breakdown of the Linux Server.
6. The TC OS is portable on the hardware provided by TMI.
7. Most of the issues related to migration from Windows to Linux are addressed.
8. Mechanism to provide better speed of applications and flow of data is incorporated.
