An online brokerage company is planning to implement a new web-based client services. Due to the mission critical nature of the network connection, a minimum reliability of R = 0.99 is set as target. The typical guaranteed reliability and cost per connection from various different and independent ISPs are similar and for one connection the reliability is R; = 0.95 and the cost is $10,000. Assume that each ISP could provide one connection (or multiple connections) that covers maximum 25% of the required peak load. Propose solutions for the network configurations of the ISPs using the following architectures and back up your proposals with the appropriate calculations. Which architecture among the three is more cost effective? a) K-out-of-n architecture b) Parallel architecture c) Stand-by architecture An online brokerage company is planning to implement a new web-based client services.
