Amazon already has Aurora: https://aws.amazon.com/rds/aurora/details/ https://aws.amazon.com/rds/aurora/details/
You're right that there's literally nothing else out there that has tight synchronization using atomic clocks, though.
- xapata 10y agoAnd because of that, Aurora's multi-zone replicas are read-only. I just noticed Google says the cross-region feature is coming later in 2017. Amazon might be planning to announce a similar change for Aurora in the coming months.
- user5994461 10y agoAurora is a toy compared to Spanner. Single region, limited backups and replication topologies, limited performances. There is yet to see if Spanner can achieve the expectations, if it does, it's a game changer.
- xapata 10y ago> achieve the expectations It has for Google internally. No reason why they can't share the service externally.
- discodave 10y agoActually, there are lots of reasons why it's hard to share a service externally. Making a service public means you have to deal with lots of new problems like billing, abuse, dealing with lots of small users instead of a few large ones, stronger backwards compatibility requirements and so-forth.
- xapata 10y agoYes, but those are orthogonal to the scaling issues that I presume user5994461 was thinking of.
- discodave 10y agoThat's kind of the point, when you make a service like Cloud Spanner public you create new scaling dimensions. New scaling dimensions means new problems to solve that are not trivial.
