The new Magewell Cloud multi-device management software provides centralized configuration and control of multiple Magewell IP encoders and decoders including the Ultra Stream family of live streaming and recording appliances, the Ultra Encode series of universal live media encoders and the Pro Convert portfolio of encoders and decoders. It also offers stream management features including protocol conversion and SRT gateway functionality. Once the Magewell hardware devices have been registered to a Magewell Cloud installation, users can remotely configure device parameters, monitor the status of each device, trigger operational functions and perform batch firmware upgrades across multiple units of the same model. Administrators can also group devices together and assign permissions for different devices or groups. Magewell Cloud simplifies one-to-many or many-to-many streaming with the Secure Reliable Transport (SRT) protocol by serving as an SRT gateway. SRT-capable Magewell devices and third-party SRT products can connect to Magewell Cloud rather than directly to each other. While the SRT protocol enables secure, reliable and low-latency transmission over unpredictable networks such as the public internet, many legacy encoders and decoders do not directly support SRT. The Magewell Cloud platform can convert streams bi-directionally between RTMP and SRT. Magewell Cloud is delivered as a Docker container, enabling deployment on Windows, Linux and MacOS computing platforms with minimal configuration requirements. Customers can run Magewell Cloud on their own private server or public cloud infrastructures such as Amazon Web Services (AWS) or Microsoft Azure and can view the host platform’s CPU, memory and network usage through Magewell Cloud’s browserbased GUI. The Magewell Cloud software is now in beta testing, with general availability expected later in Q3 2021. Users interested in beta testing a pre-release version of the software are invited to submit a request through the Magewell website.
