Editor’s noteWe’ve renamed our product suite. The VMR is now referred to as Solace PubSub+. See our products page for more information.


Today we’re introducing Release 7.2 of the VMR. It’s a big step forward for the VMR in features, performance, and scaling.

One of our major goals for this new version of the VMR was to rev up performance. With R7.2, our benchmarks indicate that the VMR is two to five times faster than the other commonly used software message brokers. We’ve tested it under a wide range of conditions including diverse message sizes and distribution patterns. We invite you to test it for yourself and let us know what you find. We think you’ll agree that the new VMR screams for all kinds of workloads.

We also know that for many of our customers, it is important that their applications work exactly the same whether they are connecting to a VMR or to a Solace messaging appliance. To that end, we’ve added a bunch of features to Release 7.2 VMR that were previously only available on the appliance, including support for:

  • Compressed client connections for use cases where bandwidth between client applications and the router is limited
  • TLS-encrypted bridge connections between VMRs for secure transfer of messages between routers
  • Client-certificates for securely authenticating client connections to the VMR
  • VMware Tools, to make it easier to manage the VMR in VMware environments

Under the hood, we’ve updated the underlying kernel, and improved the multi-threading of our software so that we can take better advantage of modern multi-core server platforms. We’ve also created the VMR Community Edition, a version that is free for you to use however, wherever and whenever you want.

The VMR is available for a variety of platforms and virtual machines – VMware, kvm, AWS, and OpenStack to name a few. We’re also excited to announce that with R7.2, the VMR is also now available as an open-beta Tile in Pivotal Cloud Foundry.

We’re committed to rapid innovation and iteration in our VMR development which means you’ll see additional “dot releases” of the VMR through the end of the year. For example:

We’ll be releasing a GA version of the VMR as a Pivotal Cloud Foundry tile.

We’ll be increasing the connection count per VMR to 10, 000 full-featured enterprise connections or IoT connections, and then growing that number by an order of magnitude for IoT connections later in 2017.

With the introduction of SEMP v2 on the VMR, we’ll be making the VMR easier to manage, and easier integrate with tools like Chef and Puppet and Ansible.

We’ll be adding support for High Availability (HA) groups of VMRs. With HA, your applications are protected against failures in the machine hosting the VMR or the associated storage, with failover to the backup VMR in the HA group fast and transparent to client applications.

You can download the VMR 7.2 Community Edition or a free trial of the Enterprise Edition now from our Developer portal. Give it a try, we think you’ll agree it is the state of the art in fast, robust messaging, and the only product that supports all the open standard ways you need to move data within your applications.
