| Component type | Description | Implementation notes |
|---|---|---|
| FIXEdge node | The FIXEdge nodes process the messages passing from and to the clients | Functionally it is FIXEdge server/FIXEdge Java server |
| Load Balancer | Load balancer redirects incoming connections to the one of the FIXEdge nodes. It is a single entry point for clients initiator sessions. | 3-rd party product is used - HA-proxy |
| Configuration Service | Configuration Service is the centralized source of the cluster configuration. It manages sessions and schedules configurations. | |
| Cluster Coordination Service | Cluster Coordination Service is used to coordinate FIXEdge nodes with each other. It is user to register other services/components, manage healthchecks. | 3-rd party product is used - Consul |
| Scheduler Service | Scheduler Service allows to manage sessions states according to the specified events. | |
| Shared FIX Storage | Shared FIX Storage is used to store FIX messages and sessions' last incoming and outgoing sequence numbers. | Oracle DB is used. Other DB systems may be used - MSSQL, PostgreSQL, etc. FO is used for FIXEdge Java solution. |
| Configuration Storage | Configuration Storage is used to store cluster configuration | Oracle DB is used. Other DB systems may be used - MSSQL, PostgreSQL, etc. |
| Configuration Tool (CLI) | Configuration Tool is used to configure the cluster | Command Line Tool |
| Log Collector (+Log Storage) | FIXEdge application logs are sent to Log Collector which provide single point to search and analyze the logs. | 3-rd party product is used - Splunk |
