I would hope that for a high-throughput DB cluster like this, they're using instance-local storage rather than EBS. If that's the case, then they're probably already taking advantage of EC2 reserved instances to save a lot compared to the on-demand prices that we usually see.
- jhk727 5y agoWe are, though we started out using EBS. As you mentioned, NVMe instance storage performs much better for our workload. We work around the lack of durability through strong automation of point in time restore/swapping in of new nodes in case of hardware failures. And yes, reservations make a massive difference economically.
