A web application hosted on Oracle Cloud Infrastructure experiences a peak traffic load of $T_p = 1200$ requests per second. Each load balancer can handle $C = 300$ requests per second. How many load balancers are required to manage the peak traffic efficiently?
Correct
In this scenario, we are tasked with determining the optimal load balancing configuration for a web application hosted on Oracle Cloud Infrastructure (OCI). The application experiences varying traffic loads throughout the day, and we need to calculate the required number of load balancers to handle peak traffic efficiently. Let’s denote the peak traffic load as $T_p$ (in requests per second) and the capacity of a single load balancer as $C$ (in requests per second). The total number of load balancers required, $N$, can be calculated using the formula: $$ N = \left\lceil \frac{T_p}{C} \right\rceil $$ where $\left\lceil x \right\rceil$ denotes the ceiling function, which rounds $x$ up to the nearest integer. For this question, assume the peak traffic load $T_p = 1200$ requests per second and the capacity of each load balancer $C = 300$ requests per second. Plugging these values into our formula gives: $$ N = \left\lceil \frac{1200}{300} \right\rceil = \left\lceil 4 \right\rceil = 4 $$ Thus, we need 4 load balancers to handle the peak traffic efficiently. This calculation is crucial for ensuring that the application remains responsive and can handle user requests without delays during peak times.

In Oracle Cloud Infrastructure (OCI), metrics and alarms are crucial for monitoring the performance and health of resources. Metrics provide quantitative data about resource usage, while alarms are set to trigger notifications based on specific thresholds. Understanding how to effectively utilize these tools is essential for maintaining optimal performance and ensuring that any issues are promptly addressed. For instance, if a compute instance’s CPU usage exceeds a certain threshold, an alarm can be configured to notify the administrator, allowing for immediate action to prevent potential downtime or performance degradation.

30. Question
A company has recently migrated its operations to Oracle Cloud Infrastructure and is keen on managing its cloud costs effectively. They have set a monthly budget of $10,000 for their cloud services. Midway through the month, they receive an alert indicating that they are projected to exceed their budget by 20% based on current usage trends. What should the company do to address this situation effectively?
Correct
Effective cost management and budgeting in Oracle Cloud Infrastructure (OCI) are crucial for organizations to optimize their cloud spending and ensure that resources are allocated efficiently. Understanding how to set budgets, monitor costs, and analyze spending patterns can significantly impact an organization’s financial health. In OCI, users can create budgets that alert them when spending approaches or exceeds predefined thresholds. This proactive approach allows organizations to adjust their usage or investigate unexpected charges before they escalate. Additionally, OCI provides tools for cost analysis, enabling users to break down expenses by service, department, or project. This granularity helps identify areas where costs can be reduced or optimized. Furthermore, organizations should regularly review their budgets and spending reports to adapt to changing business needs and cloud usage patterns. By fostering a culture of accountability and awareness around cloud costs, organizations can better manage their cloud investments and align them with their overall business objectives.
