There are minimum hardware requirements for CPU, RAM, disk, and operating system to deploy a node. You can follow the node deployment manual, which details all the steps to deploy your node on the network. Nodes can be deployed in any environment, both in the cloud and on-premise. Each entity can decide where it is best or most interesting for them.
Your node is one more component of your digital infrastructure. Therefore, you must provide it with the same type of protection, including firewall security layers, activity monitoring, and backup.
First, check the issues already resolved to see if they solve your issue has already been addressed. Otherwise, if you are operating in the Pro-Testnet environment, you must raise an issue on Github. On the other hand, if you are in the Mainnet environment you can use the client portal for individual support.
