The short version

  • Each has a real cost: Nginx open-source nginx has no admin API for changing arbitrary config at runtime; dynamic reconfiguration requires editing the config file and reloading via 'nginx -s reload'; Vault vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
  • They diverge on capability: Nginx covers High-performance web server, Vault covers Secrets management.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Nginx

  • Open-source nginx has no admin API for changing arbitrary config at runtime; dynamic reconfiguration requires editing the config file and reloading via 'nginx -s reload'
  • No official built-in GUI or dashboard for management or live metrics in the open-source edition
  • Advanced capabilities such as active health checks, dynamic upstream reconfiguration without reload, and a full API gateway feature set are exclusive to the paid NGINX Plus product, not open-source nginx
  • No published list price for NGINX Plus on the current F5 product page; pricing requires contacting sales

Vault

  • Vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
  • The Additional Use Grant forbids offering Vault to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vault
  • Each version only converts to MPL 2.0 four years after that version is published, and the Change Date is tracked per version
  • Replication, HSM support, namespaces, performance standby nodes, FIPS builds, control group authorisation, multi-factor authentication, secrets sync and lease count quotas all require a Vault Enterprise licence
  • A Vault Enterprise licence must be applied to the cluster before any Enterprise feature can be used
