People give Amazon flack but they offer solid support with reasonable escalation when you have an issue. Imo it's a bit sad Elasti Co couldn't out compete ES on their own product.

When AWS released ES you couldn't even dynamically scale cluster nodes and you had to use Amazon's special library to sign requests for IAM

There are other companies that run curated & managed SaaS on providers like AWS, GCP, etc that offer better services than the native ones. For instance, MariaDB SkySQL offers DBAs with their product and will help tune the DB for the workload vs AWS where they offer limited app-level support outside suggesting things like Performance Insights. When I looked, SkySQL was also a bit cheaper than AWS RDS for comparable hardware
