How does clustering enhance the scalability of a Node.js application?

easy📝 Conceptual Q1 of 15
Node.js - Cluster Module
How does clustering enhance the scalability of a Node.js application?
ABy converting asynchronous code to synchronous code
BBy reducing the size of the application code
CBy enabling multiple processes to run simultaneously on different CPU cores
DBy limiting the number of incoming requests
Step-by-Step Solution
Solution:

  1. Step 1: Understand clustering

    Clustering allows Node.js to create multiple worker processes that run on separate CPU cores.

  2. Step 2: Effect on scalability

    Multiple processes handle requests in parallel, improving the ability to scale with CPU resources.

  3. Final Answer:

    By enabling multiple processes to run simultaneously on different CPU cores -> Option C

  4. Quick Check:

    Clustering uses multiple cores for parallelism [OK]
Quick Trick: Clustering uses multiple CPU cores for parallel processing [OK]
Common Mistakes:
  • Thinking clustering reduces code size
  • Confusing clustering with synchronous execution
  • Assuming clustering limits requests
