Class AwsConfig

java.lang.Object

com.hazelcast.config.AwsConfig

Direct Known Subclasses:

ClientAwsConfig

public class AwsConfig
extends Object

The AWSConfig contains the configuration for AWS join mechanism.

what happens behind the scenes is that data about the running AWS instances in a specific region are downloaded using the accesskey/secretkey and are potential Hazelcast members.

Filtering

There are 2 mechanisms for filtering out AWS instances and these mechanisms can be combined (AND).

1. If a securityGroup is configured, only instances within that security group are selected.
2. If a tag key/value is set, only instances with that tag key/value will be selected.

Once Hazelcast has figured out which instances are available, it will use the private ip addresses of these instances to create a tcp/ip-cluster.
