PostgreSQL is an open-source relational database management system maintained by the PostgreSQL Global Development Group. It provides SQL-compliant, ACID transactions, MVCC concurrency, and extensibility through custom types, functions and extensions, and is used for general-purpose and enterprise database workloads.

Tensor Processing Unit (TPU) is a family of application-specific integrated circuits (ASICs) and managed services developed and operated by Google to accelerate machine learning workloads. TPUs are available as on-premises hardware and as a managed Cloud TPU service for training and inference of neural networks and deep learning models. First announced in 2016, TPUs are used inside Google's datacenters and offered to external customers via Google Cloud.

CockroachDB is a distributed SQL database developed by Cockroach Labs. It is compatible with the PostgreSQL wire protocol and supports most PostgreSQL syntax, data types, drivers, and ORMs. CockroachDB scales horizontally: every node can accept reads and writes, while data automatically rebalances across nodes and hotspot detection adjusts distribution as load changes. It can be fully managed on AWS, Google Cloud, or Azure, operated in a customer's cloud account, or self-hosted on Kubernetes, on-premises, or in hybrid environments. In the video's Form3 case, CockroachDB served as the single data store across all three cloud providers for a multi-cloud payments platform.

Amazon RDS is a hosted PostgreSQL database service from Amazon Web Services (AWS). In the cited architecture, it was used as the database for version one of a payments platform.
