Which RDS instance should I choose?

Choose RDS instances based on your database needs: db.t3 or db.t4g for small applications and development, db.m5 or db.m6i for balanced production workloads, db.r5 or db.r6i for memory-intensive databases with large datasets, and db.x2iedn for extreme performance requirements. For cost savings, consider ARM-based Graviton instances (db.t4g, db.m6g, db.r6g) which typically offer better price-performance. Use CloudPrice to compare specifications and pricing for your specific database engine.

What is the cheapest RDS instance type?

The cheapest RDS instances are the smallest T-series instances like db.t4g.micro or db.t3.micro for MySQL or PostgreSQL. For production workloads, db.t3.small or db.t4g.small offer better value with burstable performance. Reserved instances can reduce costs significantly (up to 70% savings) compared to on-demand pricing. CloudPrice provides real-time pricing comparison to help you find the most cost-effective option for your database engine and region.

How much does RDS cost per month?

RDS monthly costs vary significantly by instance type, database engine, and region. Smaller instances start at tens of dollars per month, while larger production instances can cost hundreds to thousands per month. Costs include both compute (instance) and storage charges. Storage typically starts around $0.10-0.15 per GB-month for General Purpose SSD. Use CloudPrice to compare current pricing and reserved instance options to optimize your database costs.

What's the difference between RDS instance classes?

RDS instance classes serve different purposes: T-class (db.t3, db.t4g) provides burstable performance for variable workloads and development, M-class (db.m5, db.m6i) offers balanced compute and memory for general production databases, R-class (db.r5, db.r6i) delivers memory-optimized performance for large in-memory databases and caching, and X-class (db.x2iedn) provides extreme memory capacity for SAP HANA and memory-intensive enterprise applications.

Is Aurora cheaper than RDS?

Aurora typically costs more per hour for compute than standard RDS (often 20-40% higher), but can provide better overall value through improved performance and built-in features. Aurora includes automatic replication, faster failover, and better performance which can reduce your total infrastructure costs. For small databases (under 10-20GB) with simple requirements, standard RDS is usually more cost-effective. For larger, high-availability production databases, Aurora's features often justify the premium. Use CloudPrice to compare current pricing for your specific configuration.
