Running Kafka on AWS in Production

1. Separate your instances between different availability zones

2. Use stl EBS volumes for the best price / performance ratio

3. Use r4.xlarge or m4.2xlarge if you're using EBS(these instances are EBS optimized). You can use something smaller but performance may degrade

4. Setup DNS names for your brokers / fixed IPs so that your clients aren't affected if you recycle your EC2 instances
