Essay on Linux
Flexibility and Adaptability
Even as we build your infrastructure for data acquisition to meet today’s demands, we have got to have one eye toward tomorrow. This means that our technology should be able to accommodate evolving needs quickly and easily. Linux provides data acquisition infrastructure with open standards and leverage existing technology investments (Kenneth, 1996). Linux also provides support for interoperability with external and internal services.
Reliability and Availability
A data acquisition system must be 24 hours a day, 7 days a week and 365 days a year. The cost of an outage can be staggering in lost business and eroded brand equity. The benchmark for reliability and availability is the “five nines,” as in 99.999 percent availability—this means less than five minutes of downtime over the course of a year. Linux helps in achieving five nines through multiple access points and redundancy to keep web traffic flowing and safe. (Kenneth, 1999)
Network Security
Linux is has powerful network security tools as compared to other operating system. Linux is less vulnerable to networks attacks. It provides a complete set security tools to restrict and handle all types of security attacks.
Network security presents a host of new problems for data acquisition systems. Information entered on the terminal by the user must pass along a communication link to cluster controller. Inside the network, the information passes through a number of nodes and links between nodes until it arrives at the node to which the destination service host is connected (Kenneth, 1996).
Portable Operating System
What Linux is good at is critical applications, like data acquisition systems. Analysts are expecting the market to be flooded by these systems over the next two years, presenting a strong opportunity for companies to sell their Linux services and prepackaged Linux products to hardware original equipment manufacturers (OEMs) (Craig, 2002). Linux already has accounts for 24 percent of new operating-system shipments and is expected to grow shipments at 28 percent a year, faster than all other operating systems, according to International Data Corporation....
