Why is it important to monitor and adjust resource requests and limits regularly for cost optimization in Kubernetes?
ABecause Kubernetes automatically adjusts requests and limits daily
BBecause workloads and usage patterns change over time, affecting resource needs
CBecause setting high limits always reduces costs
DBecause resource requests and limits have no impact on cost
Step-by-Step Solution
Solution:
  1. Step 1: Recognize workload variability

    Workloads change in resource consumption over time due to updates, traffic, or usage patterns.
  2. Step 2: Understand impact on resource allocation and cost

    Adjusting requests and limits ensures resources are not wasted or insufficient, optimizing cost and performance.
  3. Final Answer:

    Because workloads and usage patterns change over time, affecting resource needs -> Option B
  4. Quick Check:

    Changing workloads = Need to adjust requests/limits [OK]
Quick Trick: Adjust requests/limits as workloads change [OK]
Common Mistakes:
  • Assuming Kubernetes auto-adjusts resources
  • Thinking high limits reduce cost
  • Ignoring resource tuning importance
