  3. 3 Messaging Messaging ≠ ≠ Messaging Low-latency pub/sub Cross-cloud backbone

    Temporal decoupling Load levelling Load balancing Enterprise application integration IoT device connectivity Message-driv en beans Event-driven microservices Long-term message storage Replayable streams Event sourcing Geo-aware routing Database change data capture
  4. 4 Flexible messaging for the enterprise, cloud and Internet of

    Things Standard Protocols Broker • Queuing and pub/sub • Rich feature set • JMS 2.0 compliance • Best-in-class perf • Based on Apache ActiveMQ Artemis Interconnect • Message routing • Secure messaging backbone for hybrid cloud • Based on Apache Qpid Dispatch Router Streams • Durable pub/sub • Replayable streams • Highly scalable • Based on Apache Kafka Online • Scalable, “self-service” messaging-as-a-service utility based on OpenShift • Available for self-managed and Red Hat-managed deployments Polyglot Clients Common Management Red Hat AMQ 2019
  5. What is Apache Kafka? 5 A publish/subscribe messaging system. A

    data streaming platform A distributed, horizontally-scalable, fault-tolerant, commit log
  6. 6 Developed at LinkedIn back in 2010, open sourced in

    2011 Distributed by design High throughput Designed to be fast, scalable, durable and highly available Data partitioning (sharding) Ability to handle huge number of consumers What is Apache Kafka?
  7. Traditional Messaging 7 Queue Producer Consumer 1 2 3 Reference

    count-based message retention model When message is consumed it is deleted from broker “Smart broker, dumb client” Broker knows about all consumers Can perform per consumer filtering Throughput up to 4K/10K mes./sec.
  8. Apache Kafka 8 Kafka Topic Producer Consumer 1 2 3

    1 2 3 Time-based message retention model by default Messages are retained according to topic config (time or capacity) Also “compacted topic” – like a “last-value topic” “Dumb broker, smart client” Client maintains position in message stream Message stream can be replayed Throughput up to 1 million mes./sec.

  11. Kafka Concepts - High Availability 11 Broker 1 T1 -

    P1 T1 - P2 T2 - P1 T2 - P2 Broker 2 T1 - P1 T1 - P2 T2 - P1 T2 - P2 Broker 3 T1 - P1 T1 - P2 T2 - P1 T2 - P2 Leaders and followers spread across the cluster
  12. Kafka Concepts - High Availability 12 If a broker with

    leader partition goes down, a new leader partition is elected on different node Broker 1 T1 - P1 T1 - P2 T2 - P1 T2 - P2 Broker 2 T1 - P1 T1 - P2 T2 - P1 T2 - P2 Broker 3 T1 - P1 T1 - P2 T2 - P1 T2 - P2

  14. 14 Based on OSS project called Strimzi Container images for

    running Apache Kafka and Zookeeper Operators for managing and configuring Apache Kafka clusters, topics and users Simplified deployment on OpenShift Broker, Connect, Streams, Mirror Maker, Java clients & management tools Apache Zookeeper (as a Kafka dependency) Enterprise distribution of Apache Kafka Red Hat AMQ Streams
  15. 15 Enterprise Kubernetes A comprehensive enterprise-grade application platform, built for

    containers with Kubernetes Orchestration Orchestrates computing, networking, and storage infrastructure on behalf of user workloads Modularity Better software management through modularity Simplified Deployment Simplifies the deployment and update of software at scale High Availability & Auto Scalability Provides high availability, horizontal autoscaling, rolling updates, canary deployments
  16. Goals for AMQ Streams on OpenShift 16 Simplifying the deployment

    of Apache Kafka on OpenShift Using the OpenShift native mechanisms for; Provisioning the cluster Managing the topics and users Providing a better integration with applications running on OpenShift Microservices, data streaming, event-sourcing, etc.
  17. Challanges 17 A Kafka cluster requires; A stable broker identity

    and stable network address A way for brokers to discover each other and communicate Durable state on brokers and storage recovery To have brokers accessible from clients, directly It runs alongside a Zookeeper ensemble which requires; Each node has the configuration of the others To have nodes able to communicate each others Accessing Kafka isn’t so simple
  18. How Openshift Helps 18 Openshift provides; StatefulSets for stable identity

    and network Together with Headless services for internal discovery Services for accessing the cluster Secrets and ConfigMap for handling configurations PersistentVolume and PersistentVolumeClaim for durable storage Openshift/Kubernetes primitives help but still not easy
  19. The Operator Pattern 19 An application used to create, configure

    and manage other complex applications Contains domain-specific domain knowledge Operator works based on input from Custom Resource Definitions (CRDs) User describes the desired state Controller applies this state to the application It watches the *desired* state and the *actual* state and makes forward progress to reconcile OperatorHub.io Observe Analyze Act
  20. AMQ Streams Operators 20 Cluster Operator Kafka CR Kafka Zookeeper

    Deploys & manages cluster Topic Operator User Operator Topic CR User CR Manages topics & users
  21. Accessing Kafka 21 Broker 1 T1 - P1 T1 -

  22. Kafka’s Discovery Protocol 22

  23. Openshift Cluster Internal Access 23

  24. Openshift Cluster External Access 24

  25. AMQ Streams on OpenShift 25 Tolerations Memory and CPU resources

    High Availability Mirroring Affinity Authentication Storage Encryption Scale Down JVM Configuration Logging Metrics Off cluster access Scale Up Authorization Healthchecks Source2Image Configuration
  26. AMQ Streams Use Cases 26 Messaging Replacement of traditional message

    broker High scale, high throughput, built-in partitioning, replication, and fault-tolerance. Some limitations compared to traditional broker (filtering, standard protocols, JMS …) Website Activity Tracker Rebuild user activity tracking pipeline as a set of real-time publish-subscribe feeds. Activity is published to central topics with one topic per activity type Metrics Aggregation of statistics from distributed applications to produce centralized feeds of operational data. Log Aggregation Abstracts details of files an gives event data as stream of messages. Offers good performance, stronger durability guarantees due to replication. Stream Processing Enables continuous, real-time applications built to react to, process, or transform streams. Data Integration Captures streams of events or data changes and feed these to other data systems (see Debezium project).
