Solace PubSub+ Platform helps enterprises design, deploy and manage event-driven systems across hybrid and multi-cloud and IoT environments so they can be more event-driven and operate in real-time. The PubSub+ Platform includes the powerful PubSub+ Event Brokers, event management capabilities with PubSub+ Event Portal, as well as monitoring and integration capabilities all available via a single cloud console. PubSub+ allows easy creation of an event mesh, an interconnected network of event brokers, allowing for seamless and dynamic data movement across highly distributed network environments. PubSub+ Event Brokers can be deployed as fully managed cloud services, self-managed software in private cloud or on-premises environments, or as turnkey hardware appliances for unparalleled performance and low TCO. PubSub+ Event Portal is a complimentary toolset for design and governance of event-driven systems including both Solace and Kafka-based event broker environments.

Use standard or FIFO (first in, first out) queues depending on the number of RPS (requests per second). Use familiar tools for interacting with Amazon SQS, the HTTP API, CLI, and libraries for various programming languages. Message Queue uses fast NVMe-enabled solid-state drives to store messages. Messages are stored as multiple copies in geographically distributed availability zones. This ensures reliable storage and low latency with write confirmations. Message Queue is integrated with cloud functions, a trigger invokes a function that handles messages from a queue. Create a queue and view the number of messages and call duration in statistics. Consumers read messages from a standard queue in random order. Standard queues guarantee that each message is delivered at least once. In rare cases, a message can be received from a standard queue twice. Use standard queues when you need maximum throughput.

StreamNative redefines streaming infrastructure by seamlessly integrating Kafka, MQ, and other protocols into a single, unified platform, providing unparalleled flexibility and efficiency for modern data processing needs. StreamNative offers a unified solution that adapts to the diverse requirements of streaming and messaging in a microservices-driven environment.

Apache Pulsar’s unique architecture decouples the message serving layer from the message storage layer to deliver a mature cloud-native data-streaming platform. Scalable and elastic to adapt to rapidly changing event traffic and business needs. Scale-up to millions of topics with architecture that decouples computing and storage.

MQ provides a reliable way to communicate between services and components. Highly available, persistent by design, with best-effort one-time delivery, MQ is the most industrial-strength, cloud-native solution for modern application architecture. Supports a rich set of features including push and pull queues, long polling, error queues, alerts and triggers, and more. MQ is a global service that runs on multiple clouds and availability zones. For advanced users with critical messaging needs, queues can automatically point to alternative zones in case of an outage without having to change any code. Runs on top of cloud infrastructure and uses multiple high-availability data centers. MQ scales without the need for you to add and maintain resources yourself. Uses HTTPS/Rest-based APIs for simple and efficient cloud use. Built with MQ standards in mind for maximum flexibility and configuration.

IBM® MQ on Cloud is the gold standard for enterprise messaging, providing security-rich and reliable messaging on-premises and across multiple clouds. Use IBM MQ on Cloud as a managed offering. IBM will handle upgrades, patches and many of the operational management tasks, allowing you to focus on integrations with your applications. Your company uses a mobile app on the cloud to facilitate e-commerce transactions. IBM MQ on Cloud connects the on-premises stock system with the consumer application to give users real-time information about what products are available. Your company hosts its core IT systems in San Francisco, but packages are processed in a depot in London. IBM MQ on Cloud reliably transmits messages from one location to another. It lets the London office encrypt "send" data about every package that needs to be tracked, and lets the San Francisco office receive and process that information more securely. Both offices can trust that information won’t be lost.
