Deploying Apache Kafka as a Self-Hosted Amazon Data Firehose Alternative

Apache Kafka, managed by the Strimzi Kubernetes operator, serves as a self-hosted alternative to Amazon Data Firehose, utilizing KRaft-mode clusters and pluggable sink connectors. Similarly, Apache Pulsar provides a distributed messaging platform as a self-hosted alternative to Google Pub/Sub, featuring native multi-tenancy and tiered storage. Both guides detail deployment processes, including security via SASL/SCRAM or JWT, monitoring with Prometheus, and specific migration strategies to transition from fully-managed cloud delivery pipelines to controlled infrastructure.
