Kafka producer and consumer in seperate EC2 instance
I have 2 ec2 instances one for Kafka broker and the other for Kafka Consumer. May i know how to connect both the ec2 instance to communicate with each other. If i produce a message in my broker i need to get it in the consumer.
Basically, i am looking for that part of configuration where i need to give the consumer information in the broker ec2 instance and vice versa (whichever way it works) . Do i need to use some api or something ?
I have tried in a single node cluster and it worked.

You are trying to access from Java or manually from console?

You could improve your question by showing exactly what you've tried on a single node that works, and the error that you get when trying it across two nodes.

It does not matter you are hosting your broker in ec-2 or elsewhere as long as it is accessible to consumer.
A sample consumer in Java using StringDeserializer for both key and value. You need to use the KafkaConsumer API if you are accessing from a Java program
Properties props = new Properties();
props.put("bootstrap.servers", "YOUR_KAFKA_BROKER_ADDRESS");
props.put("group.id", "test");
props.put("enable.auto.commit", "true");
props.put("auto.commit.interval.ms", "1000");
props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");
KafkaConsumer<String, String> consumer = new KafkaConsumer<>(props);
consumer.subscribe(Arrays.asList("foo", "bar"));
while (true) {
ConsumerRecords<String, String> records = consumer.poll(100);
for (ConsumerRecord<String, String> record : records)
System.out.printf("offset = %d, key = %s, value = %s%n", record.offset(), record.key(), record.value());
}

If you're using Kafka across machines, you need to configure the listeners correctly. This article explains how: https://rmoff.net/2018/08/02/kafka-listeners-explained/

Brokers don't push messages to consumers, so you wouldn't give the information for the consumer to any broker
Any code that works against a single broker should work for more than one, assuming network settings are configured properly
