Infrastructure products
| Microservice | Description |
|---|---|
| Haproxy | Initially, load balancer: redirects incoming requests to the less loaded server. In Axxon Datacenter, also redirects requests, but using a filter: separately redirects traffic between arpserver and arpagent, and separately redirects other traffic. This is necessary because traffic between arpserver and arpagent goes over TCP via a unique proprietary protocol created by AxxonSoft, encrypted via TLS |
| Nginx | Web-server. Receives and processes individual parts of each web request, improves performance by caching static and dynamic parts of pages |
| NATS | Messaging system. Allows microservices to exchange data |
| PostgreSQL | Database. Stores all data except binary: configurations, users, domains, etc. |
| Redis | NoSQL database in RAM. Works with key-value structures |
| Minio | Database of binary files. Stores photos of faces, their previews, and video recordings |
| ClickHouse | Analytical database for AxxonData |
