Scaling up API Gateway in a Reverse Invoke setup
The procedure is same as the one described above.
To scale up API Gateway in a Reverse Invoke setup, you can perform any of the following:
Add a new node in the Green zone.
Note:
If the portClusteringEnabled setting is disabled, then you need to create internal ports in the new node to connect to the registration ports of all the API Gateway nodes in the DMZ.
Add a new node in the DMZ zone. After bringing up the new node to the DMZ, ensure that you
Explicitly establish connections from all nodes in the green zone to the new node that you added to the DMZ zone. This can be done by adding Internal port in the servers in the green zone to connect to the newly created API Gateway in the DMZ zone.
Specify same configurations in the new node as other nodes in the DMZ zone.
You can use the Port Configuration REST API to automate the port settings and allow the Load balancer to add the new node.
Note:
API Gateway instances running in the DMZ do not need to be clustered.
