Variable Costs: The actual monthly costs may vary based on usage patterns, especially for services like EC2, Lambda, data transfer, and S3 storage which are usage-based.
Annual Commitment: Consider committing to 1-year or 3-year Reserved Instances for stable workloads to reduce EC2 costs by up to 75%.
Cost Monitoring: Enable AWS Cost Explorer and Budgets to monitor spending and set alerts when costs exceed thresholds.
