Question 5 explain the following approaches to server capacity planning : Maintain excess capacity at all times. 2. Add capacity as demand requires. 3. Match capacity to demand Answer Server capacity planning is a crucial aspect of managing a successful business operation, as it involves ensuring that the server resources are able to handle the expected demand and workload. This is especially important in today's digital age where online transactions and interactions are integral parts of daily operations. In this regard, there are three main approaches to server capacity planning: maintain excess capacity at all times, add capacity as demand requires, and match capacity to demand. The first approach, maintaining excess capacity at all times, involves keeping a considerable amount of spare capacity available on the server at all times. This is done in anticipation of potential spikes in demand or unexpected increases in workload. While this approach ensures that the server can handle any sudden increase in demand, it can also be costly and wasteful if the excess capacity is not utilized. The second approach, adding capacity as demand requires, involves closely monitoring the server's workload and adding capacity only when it reaches a certain threshold. This approach is more cost-effective as it avoids the unnecessary expenses of maintaining excess capacity. However, it may lead to service disruptions if the demand exceeds the server's capacity during the time it takes to add additional resources. The third approach, matching capacity to demand, involves precisely managing the server's capacity to meet fluctuating demand levels. This is achieved through proactive monitoring and analysis of the server's workload and performance, and adding or removing capacity accordingly. While this approach may require more tracking and calculations, it ensures optimal utilization of server resources and better cost management. Overall, the best approach to server capacity planning depends on the specific needs and capabilities of a business. A combination of these approaches may also be necessary for maximum efficiency and cost-effectiveness. Proper capacity planning is essential for smooth operations and maintaining customer satisfaction.
