RDS Pricing

• Factors which affect the costs of Amazon RDS include: - Clock hours of server time: For example, from the time you launch a DB instance until you terminate it. - Database characteristics: Physical capacity of the database. Database characteristics vary depending on the database engine, size, and memory class. - Database purchase type: On-Demand DB Instances (more expensive but pay-as-you-go) or Reserved DB Instances (cheaper but longer commitment). - Number of database instances: Provision multiple DB instances to handle peak loads. - Provisioned storage: No additional charge for backup storage of up to 100 percent of your provisioned database storage for an active DB Instance. After the DB Instance is terminated, backup storage is billed per GB per month. - Additional storage: Amount of backup storage in addition to the provisioned storage amount is billed per GB per month. - Requests: Number of input and output requests to the database. - Deployment type: Deploy your DB Instance to a single Availability Zone or multiple Availability Zones. - Data transfer: Inbound data transfer is free, and outbound data transfer costs are tiered.
