The g instance is a Graviton processor, which tend to be cheaper, and preform pretty well. It's ARM, but you can switch to that without affecting your data.

Dont use Aurora. If you use MySQL or Postgresql there is a t4g.micro instance for around $12 a month

Hello, **First Understanding Your Workload** Before diving into the instance types, it's crucial to understand your specific workload characteristics: * **Memory-intensive:** Does your workload require large amounts of memory for in-memory data structures or caching? * **CPU-intensive:** Does your workload heavily rely on CPU processing power for complex calculations or queries? * **I/O-bound:** Does your workload involve frequent reads and writes to storage? * **Network-intensive:** Does your workload require high network throughput for data transfer? * **Price Sensitivity:** Do you have strict cost constraints? **Differences:** | Feature | db.r5xlarge | db.r6glarge | db.r7glarge | | --- | --- | --- | --- | | Processor |Intel Xeon| Graviton2 | Intel Xeon | | Memory | High | High | Very High | | Network Performance | Good | Good | Excellent | | Price | Medium | Lower | Higher | **Link To Documentation:** https://aws.amazon.com/blogs/aws/choosing-the-right-ec2-instance-type-for-your-application/
