Neo4j vs Trusted Postgres Architect

Neo4j is a property graph database for storing and querying connected data. It supports Cypher and GQL, ACID transactions, graph algorithms, replication, and vector search. Deployment options include self-hosted, hybrid, multi-cloud, and fully managed cloud, while the listed platform is self-hosted. Its tools include native language drivers, GraphQL and Cypher tools, visualization tools, and connectors for Confluent Cloud, Apache Kafka, cloud data warehouses, and BI tools. AuraDB Free costs nothing, billed monthly, and requires no payment method; it includes one database instance, single-zone deployment, and no service availability SLA. AuraDB Professional costs $65 a month and offers a 14-day free trial. AuraDB Business Critical costs $146 a month and includes a three-zone cluster and a 99.95% uptime SLA. AuraDB includes encryption at rest and in transit, and Neo4j provides role-based access controls. Neo4j Ops Manager administers and monitors deployments centrally. Support options range from best effort to 24x7 premium support with a one-hour response.

Trusted Postgres Architect (TPA) is a free, Ansible-based tool for deploying and managing Postgres clusters using EDB recommendations. Users describe cluster topology and configuration in declarative YAML. TPA can provision AWS EC2 instances and Docker containers, or use existing servers and virtual machines when connection details are supplied. It installs and configures Postgres and related components, including replication and backups; architecture-dependent components can include PGD, Barman, PgBouncer, repmgr, and Postgres extensions. TPA can run tests specific to the cluster architecture and platform, apply configuration changes, perform switchovers, and carry out documented zero-downtime minor-version upgrades. Its configuration documentation lists PostgreSQL, EDB Postgres Extended, and EDB Postgres Advanced Server versions 13 through 18. The tool supports self-hosted Linux deployments and offers STIG and CIS configuration options, though these do not guarantee that a cluster meets those standards. TPA does not support major-version Postgres upgrades through the `tpaexec upgrade` command. Users can extend it with custom Ansible commands, tests, and deployment hook scripts.
