Dear Amazon Web Services Customer,
We are excited to announce a reduction in Amazon EC2, Amazon RDS, and Amazon ElastiCache prices. Reserved Instance prices will decrease by up to 37% for Amazon EC2 and by up to 42% for Amazon RDS across all regions. On-Demand prices for Amazon EC2, Amazon RDS, and Amazon ElastiCache will drop by up to 10%. We are also introducing volume discount tiers for Amazon EC2, so customers who purchase a large number of Reserved Instances will benefit from additional discounts. Today’s price drop represents the 19th price drop for AWS, and we are delighted to continue to pass along savings to you as we innovate and drive down our costs.
All of your On-Demand usage will automatically be charged at the new lower rate as of March 1st. New Reserved Instance prices will only apply to Reserved Instances purchases made on or after March 6th. With the new pricing, Reserved Instances will provide savings of up to 71% compared to On-Demand instances, so you may want to take this opportunity to review your current usage and to determine if you would like to purchase additional Light, Medium, or Heavy Utilization Reserved Instances.
