Microservices - Orchestration with Kubernetes
How can namespace isolation be combined with resource quotas to improve microservices scalability?
ABy removing quotas to allow unlimited resource use
BBy limiting resource usage per namespace to prevent one service from starving others
CBy sharing quotas across all namespaces equally
DBy disabling namespaces to pool all resources
Step-by-Step Solution
Solution:
  1. Step 1: Understand resource quotas role

    Resource quotas limit CPU, memory, and other resources per namespace.
  2. Step 2: Combine with namespace isolation

    Namespaces isolate services; quotas ensure no single namespace uses all resources, improving fairness and scalability.
  3. Final Answer:

    By limiting resource usage per namespace to prevent one service from starving others -> Option B
  4. Quick Check:

    Namespace + quotas = controlled resource sharing [OK]
Quick Trick: Use quotas per namespace to control resource use and scale fairly [OK]
Common Mistakes:
MISTAKES
  • Removing quotas causes resource starvation
  • Sharing quotas ignores namespace isolation
  • Disabling namespaces loses isolation benefits
