// Abstract: PostgreSQL is a powerful, open-source object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance, but a production-grade deployment requires many complementary technologies to the database core: high availability and automated failover, backup and recovery, monitoring and alerting, centralized access control and logging, connection pooling, and so on.
Being not initially accustomed for running stateful workloads, Kubernetes with its infrastructure as a code paradigm, CustomResourceDefinition, and Operator pattern turned out to be extremely convenient for deploying and running PostgreSQL at scale.
I will talk about a few open-source project developed and maintained by database team at Zalando which anybody could use to build own PgaaS:
1. https://github.com/zalando/patroni - Tool for PostgreSQL high availability and cluster management. Integrates with K8s API and makes PostgreSQL cloud-native.
2. https://github.com/zalando/spilo - The Docker image that packages Patroni, multiple versions of PostgreSQL, and tools for backup and recovery.
3. https://github.com/zalando/postgres-operator - Implements Kubernetes operator pattern, orchestrates hundreds and thousands deployments of Patroni/Spilo clusters.
Aforementioned projects would never get to the current state without an effort of dozens of external contributors.
// Bio: During his professional career, Alexander touched PostgreSQL from all possible sides: as a Web Developer, as System Administrator, and as a Database Engineer now. Five years ago he started working on Patroni project and achieved quite a big success with it. Nowadays Patroni is used in the heart of PostgreSQL-as-a-Service on Kubernetes at Zalando to run 1000+ PostgreSQL HA clusters. Besides that, Alexander periodically reports bugs and contributes patches to PostgreSQL and some other open-source projects (usually Postgres related).
