200-301 Question 62
Single answerA company is evaluating whether to host their web application on-premises or in the cloud. The application has unpredictable traffic, with periods of high demand followed by long periods of inactivity. Which hosting option would be the most cost-effective and scalable for this scenario?
- A
Host the application on-premises using dedicated servers
- B
Use cloud infrastructure with pay-as-you-go pricing
- C
Deploy the application on a hybrid model combining on-premises and cloud resources
- D
Purchase additional on-premises servers to handle peak demand
Show answer and explanation
Correct answer: B
Explanation
For scenarios with unpredictable traffic, cloud infrastructure with pay-as-you-go pricing is the most cost-effective and scalable solution. It allows the company to dynamically allocate resources based on demand, avoiding the high costs and resource inefficiencies of on-premises solutions or hybrid models.
- A. Incorrect.
Hosting on-premises with dedicated servers may lead to underutilized resources during periods of low traffic, making it less cost-effective for unpredictable workloads.
- B. Correct.
Cloud infrastructure with pay-as-you-go pricing allows the company to scale resources up and down based on demand, making it the most cost-effective and scalable solution for unpredictable traffic patterns.
- C. Incorrect.
A hybrid model could provide flexibility, but it may introduce complexity and higher costs for this specific scenario compared to fully utilizing cloud resources.
- D. Incorrect.
Purchasing additional on-premises servers would result in higher upfront costs and underutilized resources during periods of low demand, making it less suitable for unpredictable traffic.
