Given that TeraFlowSDN follows a micro-services architecture, for the deployment, it might be better to use many clusterized servers with many slower cores than a single server with few highly performant cores.
<h4><u>Clusterized Deployment</u></h4>
<h3><u>Clusterized Deployment</u></h3>
You might consider creating a cluster of machines each featuring, at least, the minimum server specifications. That solution brings you scalability in the future.
<h4><u>Networking</u></h4>
<h3><u>Networking</u></h3>
No explicit indications are given in terms of networking besides that servers need access to the Internet for downloading dependencies, binaries, and packages while building and deploying the TeraFlowSDN components.
Besides that, the network requirements are essentially the same than that required for running a classical Kubernetes environment. To facilitate the deployment, we extensively use [MicroK8s](https://microk8s.io/), thus the network requirements are, essentially, the same demanded by MicroK8s, especially, if you consider creating a Kubernetes cluster.

<h3><u>Operating System</u></h3>
The recommended Operating System for deploying TeraFlowSDN is [Ubuntu Server 22.04 LTS](https://releases.ubuntu.com/jammy/) or [Ubuntu Server 20.04 LTS](https://releases.ubuntu.com/focal/). Other version might work, but we have not tested them. We strongly recommend using Long Term Support (LTS) versions as they provide better stability.
