Leostream, founded in 2002, is a privately held technology company based in Waltham, Massachusetts. Its flagship product is a connection broker for virtual desktop infrastructure (VDI) and resources hosted in the datacenter.


Leostream develops a vendor-neutral connection broker, which is software that maps end users to computing resources, such as desktops, that are hosted in a data center. A connection broker integrates end-user access points, including thin clients, laptops and Web browsers, with back-end systems hosting desktops and applications. It also integrates all other data center systems required for a virtual desktop infrastructure, including security, authentication, and load balancing systems.[1]

The Leostream Connection Broker provides a single interface to manage a range of operating systems, physical and virtual desktops, and display protocols commonly found in enterprise environments. Delivered as a virtual appliance, the Leostream Connection Broker supports the major hypervisors, including those provided by VMware®, Citrix®, Red Hat®, and Microsoft®.[2][3] Leostream supports both Microsoft Windows and Linux operating systems in the datacenter. [4] In addition, the Leostream Connection Broker is optimized for OpenStack® powered clouds and is a partner in the HPE Helion OpenStack program and is SUSE OpenStack Certified.[5]

Once installed, the broker is used to add desktop and application resources, define authentication servers, build pools and plans, and configure client and end-user policies. For purely physical environments, the Leostream Connection Broker is packaged as an ISO that can be installed on certain hardware.[6]

Leostream supports over ten display protocols, including Teradici PCoIP, HP RGS, and OpenText Exceed onDemand, which are tailored for systems running graphic-intense applications. The Leostream Connection Broker is also used to deliver cloud/hybrid deployments and Desktop-as-a-Service (DaaS) with desktops hosted on AWS or OpenStack clouds.[7]
