To try aws based clustering on AWS you can change the membership scheme to AWS, and then provide the following parameters in the clustering section of the axis2.xml file. Before you try this on API Manager 1.8.0 please download this jar[JarFile] files and add them as patch.
1. accessKey
2. secretKey
3. securityGroup
4. connTimeout (optional)
5. hostHeader (optional)
6. region (optional)
7. tagKey (optional)
8. tagValue (optional)
See following sample configuration. Edit clustering section in the CARBON_HOME/repository/conf/axis2/axis2.xml file as follows.
By default, Hazelcast uses port 5701. It is recommended to create a Hazelcast specific security group. Then, an inbound rule for port 5701 from s
g-hazelcast needs to be added to this security group.
Open the Amazon EC2 console.
Click Security Groups in the left menu.
Click Create Security Group and enter a name (e.g. sg-hazelcast ) and description for the security group, click Yes, Create .
On Security Groups page, select the security group sg-hazelcast on the right pane.
You will see a field below the security group list with the tabs Details and Inbound. Select Inbound.
Select Custom TCP rule in the field Create a new rule.
Type 5701 into the field Port range and sg-hazelcast into Source.
Then when we initialize cluster all nodes in same security group will be added as WKA members.
Once you done with configurations restart servers.
Then you will following message in carbon logs.

4. connTimeout (optional)

See following sample configuration. Edit clustering section in the CARBON_HOME/repository/conf/axis2/axis2.xml file as follows.
