Hi HN! I'm the lead maintainer for the Amazon pricing site known as ec2instances.info. When Vantage acquired ec2instances.info a year ago we committed to increasing development velocity on it and we have shipped several major features this year.
Today we're continuing that by adding pricing for Redshift and OpenSearch, two AWS services which use EC2 instances under the hood. Each page has on-demand and reserved pricing as well as instance specs. The pages don't have advanced specs like Concurrency Scaling for Redshift or EBS Volumes for OpenSearch but these could be added.
We’d love to hear your feedback and what you’d hope to see in the future! Feel free to comment here or email me at everett at vantage dot sh.
