Linux Means Business: A Case Study of Pakistan On-Line
When you plan a very small ISP site or corporate network with a small number of dial-in users, it may be useful to deploy Linux as a remote access server. This saves a lot of money. We are using Linux with the Comtrol Rocketport multiport PCI adapters for this purpose. One Linux system can support up to four adapters, each with 32 high-speed serial ports. Thus, in total you can have 128 ports available in a single Pentium-based computer with good throughput. Since Rocketport cards have on-board intelligent processors, these do not pose much load on the computer. Now, just by making some changes in the login procedure, you can configure many things. For example, you can set the number of simultaneous logins you will allow for a single login name.
Linux is a very useful and stable operating system for ISP services. It provides a cost-effective, user-friendly, easy-to-configure environment. The number of utilities available for ISP operation and support is excellent. The biggest advantage is that it can be used in almost any environment and provides an edge over your competitors.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
