What is Message Hub… really?

Kafka 0.9

Some additions– Multi-tenancy– Security– Confluent REST API– Administration REST API– Monitoring

10

Message Hub is… Kafka

Kafka 0.9– Took early releases– Built, tested and deployed– Deployed as Docker containers– Continuous delivery pipeline

Community involvement– Active submitting bug fixes– KIP-43 – extend SASL mechanism support

Message Hub is… Multi-tenant

Single Kafka clusterSupport up to 500 tenantsRestrictions on each tenant’s resources

– Up to 100 partitions per tenant (3-way replicated)– Max partition size 1G– Max message age 24 hours– Clean-up policy is deletion– Max message size 1M

Message Hub is… Secure

TLS introduced in Kafka 0.9Clients authenticated with SASL Plain IBM cloud security standards

– Customer message data encrypted everywhere– Data storage must be separated from public interface

Message Hub is… Secure

Throughput of 900k msgs/s– 100 byte messages– 6 clients– 1000 topics @1 partition

Latency ranges from 10 – 70ms typically

21

Message Hub is… Flexible

Kafka REST Proxy– Confluent platform 2.0– Binary message format only– No schema registry

23

Message Hub is… Managed

Kafka Administration REST interface– Used to manage topic lifecycle– Topics not auto-created– Web UI also available for manual management

Topics can be created and deleted– Topics can have 1+ partitions– 100 partition limit per tenant across all topics

24

Message Hub is… Managed

Monitoring… and lots of it!– collectd containers deployed on every host– metrics pushed locally– forwarded to central graphite + grafana dashboards– continuous testing

Automated alerts– thresholds trigger support callouts– Slack integration to notify whole team

27

Message Connect

Connect Enterprise and Cloud– Experimental Bluemix service– Messaging pipeline from MQ to Message Hub– Bluemix apps have visibility of on-prem messages– Allows connectivity with cloud analytics and other services

28

Message Hub Incubator

AMQP proxy layer– Experimental Bluemix service– Kafka is backing messaging engine– Horizontally scalable

Target is to provide interoperability with Kafka clients

29

Bluemix Dedicated and Local

Bluemix Dedicated– IBM cloud and IBM managed– Customer gets dedicated Bluemix environment– Full Message Hub cluster– Spec defined by customer requirements– Available now

Bluemix Local– Customer’s cloud but IBM managed– TBD…
