AWS vs Cloudflare

• AWS RDS entry-level instances start at $11.68/mo, whereas Cloudflare’s database offerings begin at $0.00/mo and cap at $5.00/mo.
• Storage overages differ by an order of magnitude: AWS charges $0.12/GB for additional disk space, while Cloudflare charges $0.01/GB.
• Memory allocation is static on AWS, offering between 1 GB and 8 GB of RAM, while Cloudflare utilizes a more elastic model ranging from 0.128 GB to effectively unlimited capacity depending on the specific serverless request volume.
• AWS RDS enforces a strict $0.09/GB egress fee for data leaving the database, a cost vector that simply does not exist in the same way for Cloudflare's edge-local database storage model.

AWS RDS remains the standard for traditional applications requiring predictable performance on dedicated hardware like AMD EPYC or Intel Xeon processors. When your application requires a fixed 2 vCPU allocation and deep control over replication, the $116.07/mo ceiling for mid-range instances is a known quantity that enterprises build into their budgets. However, the operational overhead of managing connection pools and IOPS provisioning is entirely on the user.

Cloudflare targets a different segment, focusing on distributed data access with minimal footprint. By providing 1 GB to 10 GB of included storage, they cater to light, read-heavy workloads that benefit from edge proximity. While AWS RDS is better suited for heavy write-intensive relational workloads that demand strict ACID compliance and high-availability multi-AZ deployment, Cloudflare provides a significantly cheaper path for developers who need to keep database latency low for global users without the complexity of managing traditional RDS clusters. Choosing between them comes down to whether you need a dedicated server instance or a lightweight, distributed data store.
