This model eliminates capacity planning headaches but costs more per operation. Provisioned capacity requires upfront planning but delivers significant savings for consistent workloads. You reserve specific read/write units and pay whether you use them or not. Auto-scaling helps optimize provisioned capacity, but sudden traffic spikes can trigger throttling or expensive on-demand charges.

Firebase’s Usage-Based Billing Model

Firebase Real-time Database and Cloud Firestore follow straightforward usage-based pricing that scales with your app’s growth. Real-time Database charges per GB of data transfer, while Firestore bills for document reads, writes, and deletes plus storage costs. This transparent model makes budgeting easier for most developers, though costs can escalate quickly with high-frequency operations. Firebase’s free tier provides generous limits for small projects, but production apps often exceed these quotas rapidly. The pricing stays predictable until your app reaches millions of operations monthly.

Hidden Costs and Long-Term Financial Impact

Both platforms harbor unexpected expenses that can blindside developers during DynamoDB vs Firebase cost analysis. DynamoDB’s backup, global tables, and data transfer fees add up quickly, especially for multi-region deployments. Firebase charges for bandwidth, authentication, and cloud functions separately from database operations. Long-term storage costs favor DynamoDB for large datasets, while Firebase becomes expensive with frequent real-time updates. Consider your app’s growth trajectory carefully – Firebase suits rapid prototyping with predictable early costs, while DynamoDB rewards careful optimization and scales more economically for enterprise workloads.
