Reverse Proxy Server for Load Balancing

Reverse Proxy Server for Load Balancing

The REST Operations Hub manages the life cycle of the reverse proxy server process that performs the load balancing, and routes the API requests to the target Data Integration Service process nodes.
The REST Operations Hub is grid enabled. You can use the REST Operations Hub for the execution statistics API requests. The reverse proxy server routes the Data Integration Service API requests and performs the load balancing to route requests across nodes in a grid that belongs to the Data Integration Service. The reverse proxy server uses an Nginx server to route requests to the target Data Integration Service.
The REST API requests on the reverse proxy server port has a maximum timeout of one hour. You can view the following reverse proxy server logs under
<Informatica installation directory>/logs/node name>/services/Rest operations hub/
:
  • Reverse Proxy Server access.
  • Reverse Proxy Server error.
The following image shows the reverse proxy server performing the load balancing for API requests across two nodes on the Data Integration Service:
The reverse proxy server manages the API requests from a client, performs load balancing, and routes them to the Data Integration Service nodes in a grid.
The reverse proxy server manages the Data Integration Service API requests from a client and routes them to the nodes in a grid that belongs to the Data Integration Service:
  • Directory for Data Integration Service node process logs. Default is
    . The reverse proxy server routes the mapping run request to the Data Integration Service 1 and performs the load balancing across free Node 1 and Node 2.
  • The reverse proxy server routes the compare mapping request to the Data Integration Service 2 and performs the load balancing across free Node 1 and Node 2.
