# Connecting Transformers

Graph models can be designed in the Graph.Build Studio, and then generated from existing data sources (SQL / JSON / CSV / XML ) using Graph.Build Transformers.

There is no limit to the number of Transformers in any given architecture.

Transformers run stand-alone, and it is recommended to have a 1:1 relationship between data sources and transformers, as illustrated here:

To design graph models, connect Transformers to the Studio.

1. Select `Connected Transformers` , `Add New Transformer`&#x20;

2. Connect to all transformers in your architecture.

The ECS task definition used in [create & run ECS services & tasks](/EGeX4aTAJLlpg9Hh8kfl/getting-started-tutorial/installation/aws/create-and-run-ecs-services-and-tasks-v2.md) deployed one Semi-Structured Transformer, and one SQL Transformer.

Connect to each Transformer using the host machines ip address (or loadbalancer DNS if you have one) and the **host port** instead. e.g.

```
http://<machine-ip>:9603
```

```
http://<loadbalancerDNS>:9603
```
