MongoDB Ops Manager vs Trusted Postgres Architect

MongoDB Ops Manager is self-hosted software for organizations running MongoDB on their own infrastructure. It covers deployment, administration, monitoring, backup, recovery, and scaling through a graphical interface and REST API. Automation handles work from cluster creation through maintenance. Monitoring visualizes and alerts on more than 100 performance metrics. Backup options include cluster-wide snapshots, continuous incremental backups, and point-in-time recovery. Performance Advisor finds slow queries and proposes index or schema changes. Administrators can add or remove nodes, rebalance data as topology changes, and perform rolling upgrades and index builds. Enterprise Advanced supports on-premises, private-cloud, and hybrid-cloud deployments, with security integrations and 24/7/365 expert support under a response SLA. MongoDB offers a free download for evaluation, while Ops Manager is provided through an Enterprise Advanced subscription. Listed platforms include Debian, Ubuntu, Red Hat, CentOS, SUSE, and Amazon Linux.

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.
