AWS - Cost Optimization
A company wants to minimize data transfer costs between two AWS regions. Which approach is best?
AUse S3 Transfer Acceleration between regions
BTransfer data via the public internet
CKeep all data transfer within a single region
DUse AWS Direct Connect to link the regions
Step-by-Step Solution
Solution:
  1. Step 1: Analyze cost-saving strategies

    Keeping data transfer within a single region avoids inter-region transfer charges.
  2. Step 2: Evaluate other options

    Direct Connect reduces internet costs but still charges for inter-region; Transfer Acceleration adds cost; public internet is costly and less secure.
  3. Final Answer:

    Keep all data transfer within a single region to minimize costs -> Option C
  4. Quick Check:

    Single region transfer = Lowest cost [OK]
Quick Trick: Avoid cross-region transfers to save costs [OK]
Common Mistakes:
  • Assuming Direct Connect eliminates all transfer costs
  • Thinking Transfer Acceleration reduces cost
  • Ignoring benefits of single region data locality
