Amazon EventBridge vs Redpanda

Amazon EventBridge is a serverless event broker for applications that respond to events from applications, SaaS services, and AWS services. Event buses route events across AWS accounts, and subscriptions can combine filters, targets, and retry policies. Buses support tens of thousands of subscribers, retention for up to 365 days, and JSON, Avro, Protobuf, and Cloud Events formats. EventBridge also supports ordered delivery and sharing a bus across accounts in an AWS Organization through AWS Resource Access Manager. Pipes connect endpoints point to point, with optional transformation, filtering, and enrichment. Supported SaaS sources can route events to AWS service targets; listed partners include Adobe, Datadog, MongoDB, Shopify, Stripe, and Snyk. API destinations send events from a bus or pipe to web applications on public or private networks. Monitoring uses CloudWatch metrics, with logging to CloudWatch Logs, S3, or Kinesis Data Firehose. IAM access controls, VPC endpoints, and TLS 1.2 encryption in transit are supported. AWS lists several compliance standards and HIPAA eligibility, while customers retain responsibility for their own compliance obligations.

Redpanda is an event-streaming platform for storing real-time events in ordered topics that can be replayed, with access through the Apache Kafka API. Its Kafka compatibility is intended to let existing applications and tools continue without rewrites or changes. The platform uses a native C++ architecture, runs as a single binary, and has no external dependencies. Redpanda Connect supplies more than 300 pre-built connectors for sources, sinks, processors, databases, APIs, cloud services, and AI pipelines. Native Apache Iceberg support and Iceberg topics let streams be materialized into lakehouse-ready tables. Deployment options include Serverless, managed BYOC on AWS, GCP, or Azure, and self-managed installations on bare metal, virtual machines, Kubernetes, or Docker. Redpanda also lists stream processing, a schema registry, both delivery guarantees, and client support for Java, C/C++, Go, Python, Rust, and Node.js. The maker states that its platform delivers 10x lower tail latencies than open-source Kafka.
