 The reason you don't want to disable the concurrency limit is because of your database server. A database server can only have a certain number of active database connection if you reach that limit, you will start seeing database connection errors. To prevent this, you want to keep your `concurrency` value below the number of maximum connections allowed by your database server.
 
-The number of database connections that a database server can have depends on the type. Ymir supports a lot of different database types. Below is a list of all `t3` instance types with their maximum number of connections.

-If you want to access private subnet resources, you'll need a [bastion host][2] to do so. A bastion host is a small (`t3.nano`) SSH accessible EC2 instance that resides on your public subnet. You connect to it and then from there you can connect to resources on your private subnet.

 You can add a bastion host to your network by using the `network:bastion:add` command. Once the bastion host created, the Ymir CLI will return the SSH private key used to connect to it.
