Study Notes

AWS Pricing Philosophy

AWS pricing philosophy is to pay for what you use, with no long-term contracts and no upfront expenses.
You only pay for the services you consume, with the flexibility to start or stop using a product at any time.

Utility-Style Pricing Model

Pay for what you use: pay only for the services that you consume.
Pay less when you reserve: discounted rates for reserved instances.
Pay less when you use more: discounted rates for bulk usage.
Pay even less as AWS grows: economies of scale benefit customers.

How AWS Pricing Works

Compute: charged per hour/second, varies by instance type (Linux only).
Storage: charged typically per GB.
Data transfer: outbound is aggregated and charged per GB, inbound is free (with some exceptions).

Benefits of AWS Pricing

Hard benefits:
- Reduced spending on compute, storage, networking, security, and personnel.
- Reductions in hardware and software purchases (capex).
- Reductions in operational costs, backup, and disaster recovery.
Soft benefits:
- Increased developer productivity.
- Improved customer satisfaction.
- Agile business processes that can quickly respond to new and emerging opportunities.
- Increase in global reach.
