  • GeoIP configuration decisions
  • Logging of HTTP transactions locally or to syslog
Additional Features
Recommended Hardware
NGINX Plus was designed and optimized for use on generic server hardware. For an edge server capable of serving 3 to 6 Gbps of live traffic and 20,000 to 50,000 requests per second, we commonly recommend the following:
  • 2 modern x86_64 CPUs with 4 to 8 cores per CPU
  • 16 to 32 GB RAM
  • 6 x 250-GB SSD drives (if required for cache and storage)
  • 10-GbE Intel networking card
  • nginx-plus: Standard NGINX modules and additional NGINX Plus features (see the Modules in the NGINX Plus Package section below). Supports HTTP/2.
  • nginx-plus-extras: NGINX Plus with additional modules: GeoIP, Headers-More, Image Filter, Lua, Phusion Passenger, Perl, Redis, RTMP, Set-Misc, and XSLT (see the Modules in the NGINX Plus Extras Package section below). Supports HTTP/2.
