Performant, flexible and scalable​
event brokers as a service​

Event brokers are modern message brokers that support event-driven message exchange patterns across a variety of applications, devices and environments.​

PubSub+ Event Broker is what Gartner calls an “advanced” event broker, which means it does even more. That’s what the “+” is all about:​

publish-subscribe messaging pattern​

  • plus queuing​
  • plus streaming​
  • plus replay​
  • plus request-reply​

over open protocols and APIs​

with enterprise-grade performance. ​

Access all advanced features through Mission Control, while we do all the heavy lifting to dynamically deploy, upgrade, patch, and operate your services. We engineer it all to be secure, resilient, and cost-optimized so you can focus on building applications.​

Why it’s great for enterprises

PubSub+ Event Broker: Cloud delivers the serious performance enterprises need from their event broker infrastructure, including low latency, high availability, security, WAN optimization and more – without all the management hassles.

Flexible Deployment Options

  • Deploy your event broker services in public clouds in our SaaS or within your virtual private clouds, and in cloud and on premises Kubernetes environments.

Offload Operations

  • You don’t need to build, set-up, scale or troubleshoot your event broker infrastructure. We monitor the service 24×7 and perform in-service upgrades, so your messages always get where they need to go, and are cost optimized no matter where they are deployed.

Easily Scale

  • Connect messaging services in multiple locations into an event mesh that you can visualize and manage from a single pane of glass. Easily grow your mesh with simple click-to-connect functionality.

Robust Security

  • Fully control where your data resides with exclusive control over your data at rest and in motion along with user accounts and permissions. Log events reported to corporate monitoring systems and integrate with identity management systems. Learn more.

Reduce Costs

  • Flexible service sizes to meet your needs. Take advantage of annual, committed-use pricing, as well as “pay-as-you-use” billing to minimize cost while maximizing flexibility by scaling infrastructure up and down, on demand. Deployments constantly optimized by Solace engineering to minimize IaaS resource costs in each cloud for every potential broker deployment.

Stay in Control

  • See and manage what’s happening across your system. Application events can be reported to a centralized, proactive monitoring tool – PubSub+ Insights and access can be controlled so the right people have the information they need.

Deploy anywhere, manage centrally.​

PubSub+ Cloud offers the best enterprise-grade messaging as a service available in virtual private clouds from AWS, GCP and Azure.​

This allows you to combine the agility of SaaS with the control and security of a private cloud. Just like public clouds, you can easily lifecycle manage your messaging services in virtual private clouds (VPCs), using PubSub+ Mission Control to dynamically deploy, software upgrade, patch, and operate Solace event broker services, confident that they are engineered by Solace to be secure, resilient, and cost-optimized for every environment.
