To optimize cost after migrating Hadoop to cloud-native, which combination is best?

AUse on-demand instances only and keep all data in hot storage

BUse spot instances for compute and lifecycle policies for data storage

CUse reserved instances but no data lifecycle management

DKeep Hadoop on-premises to avoid cloud costs

Step-by-Step Solution

Solution:

Step 1: Identify cost-saving cloud features
Spot instances reduce compute cost; lifecycle policies move data to cheaper storage tiers.
Step 2: Compare options
On-demand and reserved instances cost more; no lifecycle policies increase storage cost.
Final Answer:
Use spot instances for compute and lifecycle policies for data storage -> Option B
Quick Check:
Cost optimization = spot instances + lifecycle policies [OK]

Quick Trick: Combine spot instances and storage lifecycle rules to save cost [OK]
