Setting up a production AWS MSK Kafka cluster involves a series of detailed steps, including configuring networking settings, choosing between private and public access, and deciding on a serverless or provisioned cluster type based on expected throughput. For private access, the setup typically involves using a private VPC with designated subnets across multiple availability zones to ensure reliability, while public access requires specific security configurations such as enabling SASL/SCRAM authentication and encryption. Once the cluster is established, managing access control lists (ACLs) is essential for securing communication between producers and consumers, requiring a temporary private access setup for configuration. Additionally, creating topics and monitoring the cluster with tools like provectuslabs/kafka-ui helps maintain operational efficiency and troubleshoot issues, particularly by providing insights into broker states, partition replication, and consumer group activity. The choice between serverless and provisioned clusters depends on workload requirements, with serverless clusters offering automatic scaling for lower throughputs and provisioned clusters providing consistent performance for larger environments.
