During his professional career, Alexander touched PostgreSQL from all possible sides: as Web Developer, as System Administrator, and as a Database Engineer now. About four years ago he started working on Patroni project and achieved quite a big success with it. Periodically he reports bugs and contributes patches to PostgreSQL and some other open source projects (usually postgres related). He is a regular speaker at different postgres events.

At a blistering pace and for a variety of reasons, companies are migrating their on-premise database infrastructures to cloud-based solutions - to save costs on hardware, tame the impact of disaster recovery, or even to improve security. Zalando is not an exception: more than two years ago we migrated our first production services to AWS.

In addition to the fully managed database services like RDS and Aurora, Amazon offers a wide spectra of EC2 Instances with different types of performance and price. Without a lot of experience in running cloud databases it’s not easy to make the right choice, and as a result you will either have pure database performance or will overpay for over-provisioned resources.

In this talk I will compare different ways of running PostgreSQL on AWS, explain why we decided to run most of our databases on EC2 Instances instead of RDS, how we chose EC2 Instance types and EBS Volumes, which AWS CloudWatch metrics MUST be monitored (and why), and what problems we hit plus how to avoid them.
