Using PostgreSQL to Create Successful Microservices Data Architectures

PostgreSQL provides the building blocks for scalable, reliable, and agile data architectures that address the three key architectural challenges:

1. Effective scalability
2. Modular APIs to give development teams the ability to move fast
3. Efficient cross-service data sharing and aggregation

Achieving effective scalability

1. To support high-volume workloads, relational transactional databases can be scaled horizontally by breaking them into smaller components that run on separate servers. PostgreSQL provides two practical approaches for scaling Modular services that can be distributed to multiple servers. For example, if the Scooter Schedule service needs more capacity, it can be moved to a separate server, and the other services keep sharing the original hardware.
2. Fleets of services that work in parallel. For example, when the rental business explodes, we create three separate instances for the East Coast, the...
