## Figure 5-3 IBM MQ Multi-Cloud for mission-critical communication 

Messaging is traditionally administered by dedicated teams within IT. “As-a-service” delivery lets enterprises create self-service portals that enable line of business (LOB) or individual users to request changes to the messaging infrastructure independently. For example, they can create or delete queues or provision new resources for applications. 

Implementing MQ as a service can enable enterprises to increase agility and efficiency, since resource provisioning can be accomplished faster and more dynamically. It can also improve usability and internal consistency. Messaging middleware naturally works well within serverless or microservices architectures common in cloud-native development. It’s also being offered in a cloud-hosted service model. In this model, your MQ handles all the provisioning, installation, and maintenance of your messaging infrastructure, and is hosted in the cloud (for example IBM and AWS clouds). 

## 5.7 Event Streaming: IBM Event Streams

IBM Cloud Pak for Integration includes Apache Kafka as the event streaming capability. IBM builds on the open source technology and enhances the ease of use to be truly ready for enterprise deployments. This is provided on public and private cloud environments to meet the needs of clients. IBM was the first supplier of a managed Apache Kafka offering in 2015 on the IBM Cloud. IBM Event Streams on IBM Cloud provides both multi-tenant and single tenant options, and this experience of running a managed service has been rolled into our on-premises private cloud offering. This capability is also sold separately as IBM Event Streams. In either model, it can run on-premise as a fully containerized offering, allowing the deployment to benefit from cloud-native best practices such as easy installation, management, and scaling of the solution. Out-of-the-box high-availability is pre-configured, so you can replicate streams across the globe for disaster recovery, thereby satisfying the requirements for mission-critical use.
