Barracuda Web App Firewall tech stack / backend infrastructure
Makes use of the following, not sure if its the primary way the firewall is implemented:
NGINX https://nginx.org/
Rules: Snort (Open Source Intrusion Prevention System) https://snort.org/
Seems to utilize mostly Ruby for its infrastructure. Snort rules appear to be called with fast-cgi via NGINX.
This is the Bunny CDN tech stack / backend infrastructure
Anti-DDoS proxy: DPDK https://www.dpdk.org/
Caching & logic: OpenResty https://github.com/openresty/openresty (https://openresty.org/en/) (formerly NGINX)
Hosting provider: https://www.datapacket.com/ (also uses a few others depending on the location)
DNS hosting provider: https://www.datapacket.com/ (bare metal anycasted DNS)
This is the Cloudflare tech stack / backend infrastructure (I want to thank Cloudflare for being so open about their infrastructure and services. They are arguably one of my biggest inspirations.)
Proxy: Pingora [Rust] [Apache-2.0 license] https://github.com/cloudflare/pingora (Formerly, Cloudflare used NGINX)
REST APIs: Golang (mostly) (runs on kubernetes pods)
Databases: PostgreSQL (for REST API and Dashboard) ClickHouse for logs
This is the Fastly tech stack / backend infrastructure
Reverse proxy / TLS termination / load balancing: h2o https://github.com/h2o/h2o/tree/master [MIT license] (https://h2o.examp1e.net/configure/proxy_directives.html)
Caching server: Varnish Enterprise https://www.varnish-software.com/products/varnish-enterprise/ [not open source] (there is an open source version of varnish)
Authoratative DNS server: NSD https://github.com/NLnetLabs/nsd [BSD-3-Clause license] (https://www.nlnetlabs.nl/projects/nsd/about/) (does not offer authoratative DNS to customers, but does give customers a CNAME that is tied to Fastly nameservers running NSD)
Web App Firewall (WAF): Signal Sciences https://github.com/signalsciences [not open source] (https://www.fastly.com/products/web-application-api-protection)
This is the AWS (Amazon Web Services) CloudFront tech stack / backend infrastructure
Proxy: NGINX https://nginx.org/ (an in-house proxy built with Rust is used if the client protocol is QUIC)
Cache: Squid https://www.squid-cache.org/
