Choosing a deployment environment

Pexip Infinity supports a wide range of network scenarios, from small, local, private deployments to large, global, cloud-based implementations. How many Conferencing Nodes you deploy, where they are located, and the hypervisors you use will depend on the makeup and requirements of your individual organization.

While your Pexip authorized support representative is the best person to advise you on the most appropriate deployment environment, below are some of the factors to consider.

On-prem, cloud or both?

On-premises deployments use your own network, hardware and hypervisors. You will need to source appropriate servers to host the Management Node and Conferencing Nodes (for more information see Server design recommendations). You will also need to consider whether the majority of users are connecting from within your private network or whether you will have users connecting externally, and therefore whether your Conferencing Nodes need to be publicly accessible. If you already have a mature IT network with datacenters in appropriate locations, this may be a suitable option.

Cloud deployments use Microsoft Azure, Amazon Web Services (AWS) or Google Cloud Platform (GCP) to host some or all of the Pexip nodes. This option does not require initial investment in hardware, but you will instead pay for usage.

You can also deploy Pexip Infinity using a combination of on-prem and cloud, with the Management Node and some Conferencing Nodes deployed within your own network, and other Conferencing Nodes deployed using a cloud service, for increased flexibility. You can even set up Dynamic bursting to a cloud service to give you temporary increases in capacity whenever you need it.

You don't have to stay committed to one particular deployment environment, and you can always increase or decrease the number of Conferencing Nodes as your capacity requirements evolve. You could, for example, start with an on-premises deployment and then add more cloud-hosted nodes later.

For more details on the on-prem and cloud options, see Network deployment options.

Hypervisor

For on-prem deployments, you will need to install a hypervisor on your servers before you can deploy the Management Node and Conferencing Nodes.

Pexip Infinity currently supports four hypervisors:

  • VMware is an independent product with a range of features, dependent on the licensing options you chose.
  • Microsoft Hyper-V is included with Windows Server and also offers a range of features.
  • KVM and Xen are open-source options that are not as feature-rich.

For more information, see Supported hypervisors.

Number, location and role of Conferencing Nodes

The capacity of your Pexip Infinity deployment, in terms of how many calls can be handled at any one time, is largely determined by the number of Conferencing Nodes you deploy. To optimize the conferencing experience, we recommend that, where possible, you locate Conferencing Nodes close to each of your main user bases. For example, if the majority of your users are located in three main offices then you should consider concentrating the majority of your Conferencing Nodes among those locations. If however the majority of your users are spread across multiple geographic locations, if possible you should deploy Conferencing Nodes evenly among your datacenters.

You must also consider the role of your Conferencing Nodes, in terms of which nodes will be accessible to the client devices and endpoints that need to participate in conferences. A Conferencing Node can have either a transcoding or a proxying role. Transcoding Conferencing Nodes are required in all deployments; they manage all of the media processing required to host a conference, and can also handle direct connections to/from endpoints if required. Proxying Edge Nodes are optional; they handle signaling and receive and send the media to/from an endpoint or device, and then forward it on to a Transcoding Conferencing Node for processing.
