Class S3_PING

java.lang.Object

org.jgroups.stack.Protocol

org.jgroups.protocols.Discovery

org.jgroups.protocols.FILE_PING

org.jgroups.protocols.aws.S3_PING

Direct Known Subclasses:

NATIVE_S3_PING

public class S3_PING
extends org.jgroups.protocols.FILE_PING

This implementation uses the AWS SDK in order to be more solid and to benefit from the built-in security features like getting credentials via IAM instance profiles instead of handling this in the application.
