/**
 * The AWSConfig contains the configuration for AWS join mechanism.
 * <p>
 * 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.
 * <h1>Filtering</h1>
 * There are 2 mechanisms for filtering out AWS instances and these mechanisms can be combined (AND).
 * <ol>
 * <li>If a securityGroup is configured, only instances within that security group are selected.</li>
 * <li>If a tag key/value is set, only instances with that tag key/value will be selected.</li>
 * </ol>
 * 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.
