AWS - Architecture Best Practices
Consider this AWS Lambda function usage pattern: it runs 1000 times per day, each execution lasts 1 second, and uses 128 MB memory. Which change will reduce cost the most?

Step-by-Step Solution
Solution:
Step 1: Understand Lambda cost factors
Cost depends on memory size and execution duration multiplied by invocations.Step 2: Evaluate options
Increasing memory may reduce time but might increase cost; decreasing memory may increase time; optimizing code reduces time without increasing memory.Final Answer:
Keep memory at 128 MB and reduce execution time by optimizing code -> Option DQuick Check:
Optimize code to reduce time = save cost [OK]
Quick Trick: Lower execution time saves more than just lowering memory [OK]
Common Mistakes:
- Assuming more memory always saves cost
- Reducing memory without checking time
- Increasing execution time to batch
