Linux Migration

Is your network running on a proprietary Operating System? Are you expanding your network and worried about investing a lot of money in software licenses? Are you going to provide an Operating System + Office Suite at the cost of the computer its running on? We can help you migrate to Linux. Linux is a very secure, stable, reliable Operating System liked for its Speed and Robustness.

There are three ways you can migrate

1. You may in need of a solution natively present in Linux, like E-mail server, File server, Desktop System to run Office Suites, etc. You can run Linux without changing anything in your present setup. Linux File formats and Networking Protocols are compatible with other Operating Systems making Linux coexist on the same Network. Linux can be used for these tasks as easily as you use any other Operating System. Linux only gives you more security and stability at a comparatively very lower investment.

2. You may have already invested a large amount of money on some proprietary software and you would like to keep it. Software from other Operating Systems can usually run on Linux. That way, our team of engineers can test if your application runs well on Linux, If there are no issues, you can save a lot on the client side by not having to buy expensive software licenses.

3. You may want to port an existing application to Linux or want to build an application from the scratch. Linux makes a wonderful platform to run applications. Once your requirements are analyzed, a custom software solution can be deployed which saves money you would typically spend buying expensive Operating System or Database System licenses.

Mail Server

Linux is the preferred Operating System that is deployed as a Mail Server in an organization of any size. Since Linux systems rarely crash or malfunction, you can be assured that a mail server can run continuously without frequent downtime leading to loss of mails.

The savings are also tremendous since you do not have to pay for any extra users you create accounts in the system. Performance wise, Linux can outperform any other operating system in low resource usage and sheer speed.

If you are more worried about security, you can opt to have your Mail Server deployed on OpenBSD, the most secured operating system on the planet. This solution provides total peace of mind as far as security issues are concerned.

There is also support for the popular protocols like SMTP, POP3 and IMAP.

Proxy Server

You can't have a secured Proxy Server if your underlying operating system is insecure in nature. Linux Proxy Servers can provide excellent customizability and configurability while still being extremely secure. Linux based proxy servers can provide time based browsing to a particular set of users or sub net or block sites that you do not want your users to see.

Linux Proxy Servers can also provide Local Caching sometimes conserving bandwidth up to 35%!

Once configured, Linux Proxy servers require little maintenance. An access log can also be maintained if need be.
 

Thin-Client Implementation

When it comes to investing money on hardware, its wise to think about the nature of the job the specific system is supposed to do. If the system is just going to run a particular application like your company's ERP package, or it is to be used for email/browsing to run Office Applications, then why invest in a full fledged system when a thin client can do the job.

What is it?
A Thin Client is a computer that comes with no hard disk, CDROM drive or floppy disk drive. It boots from a server and runs application programs from there.

Its easy
From the administrator's view point, its simple to manage. There are no difficult backup procedures. All files are stored on a central server.
For the user, its easy because he/she finds it no different from a usual computer. Once switched on, the booting is transparent and all applications and drive space is available to the user as if he/she is sitting at a normal computer.
Its also light on the management since the thin clients do not cost as much as the normal computers. Remember they don't have disk drives like a normal machine.

Network Security Solutions

Is your network connected to the Internet? You must be reaping the benefits of the Internet in terms of communication and easy access to information. But remember you may have your valuable data on you network. Since you are on the Internet, you are vulnerable to attacks from it. Simply, services like mail and web you provide may be disrupted or worse, your company information can be compromised. This requires proper security solutions to defend your network while still keeping you and your users happily on the Internet.

Welcome to the world of Linux and other secure operating systems like OpenBSD. These platforms have a good security model which other operating systems try to emulate. OpenBSD is the most secure operating system in the world. On the server side, just like Linux, it can do wonders. Firewalls are built into the core component called the kernel. All network traffic has to pass through this core component. Here it is scrutinized and subject to tests. Only when it should be allowed, it will be. Rules can be set with a high level of flexibility.

Your existing network setup need not be disturbed. A secure firewall solution can just sit in between the Internet and your network without ever disturbing it.

High Availability and Load Balancing Server Solution

Are your servers crashing trying to serve really huge demands? Is your network so busy -your servers are no longer able to cope up with the demands? Open Source solutions like Linux can come to the rescue. A clustered infrastructure can handle the load more gracefully than a single server that takes all the load. Load can automatically be balanced among a set of servers, thus making the network more responsive and quick. This solution also applies to Web Servers as well. You can make your busy web site respond much better with a cluster of Web Servers.

Print Server/File Server

Linux Print or File Servers can be a good saving in terms of costs and maintenance efforts. Linux is an Operating System that is able to talk many Network Protocols, even those that are primarily used with proprietary operating systems. Thus it is able to communicate and co-exist in networks consisting of many different operating system and able to integrate seamlessly. A Linux file server or Print Server can for example, service requests from Windows or Netware Clients.

Authentication Server(NIS or LDAP)

Large networks that are not properly managed can become an administration nightmare. When users switch from department to department or even simply from machine to machine, they loose their settings, address book, or worse, they might just not have an account on the new machine. This calls for a centrally administered directory server where user names, passwords, address book entries and other preferences can be stored. Linux can provide a central authentication server with other features such as an address book. Thus the user can have a single secure password for many services which is centrally managed.

Voice over IP Solutions

Voice Over IP, or VOIP is changing the way people communicate using voice. Since traditional telephone lines are costly, especially for placing long distance calls, the use of the Internet to place calls is fast gaining popularity. The cost reductions are dramatic and the savings are evident. Using VoIP, you can communicate longer and better without worrying about your budget. VoIP comes in different flavors depending on the end point of the communication. VoIP can be:

1. PC to PC
2. PC to Phone
3. Phone to PC
4. Phone to Phone

Bandwidth Management

Bandwidth is a very important resource for any organization. Different people or different departments within your own organization have different bandwidth needs. As an example, a department that deals with only sending and receiving e-mail does not need to be connected to the Internet at 512 Kbps. Any unnecessary downloads from that particular department can deny bandwidth to other important departments that depend more on bandwidth. The idea is to divide bandwidth among departments in a controlled fashion providing each one as much bandwidth as it needs.

A Linux Bandwidth Management Solution can be combined with a Linux Firewall Solution to provide a robust Firewalling and Bandwidth Management Solution all using one machine.

Web Server Solutions

Renting Web Server space is a solution for small organizations. To take full advantage of many different technologies and web solutions, one needs to have a “own” web server. The Internet itself consists of many Web Servers. Of these, over 70% run the Apache Web Server that primarily runs on Linux (For statistics see www.netcraft.com).

The Apache Web Server is a very secure, stable and flexible Web Server Solution. Combined with the robustness of Linux, the Apache Web Server's full potential is realized. Many different sites can also be hosted on the same physical server. The Cost benefit apart, the Apache Web Server based on Linux is a a Web Server that delivers performance that beats other Servers hands down.
