Can you make your own server in ARK?

I'm curious, is it possible for individuals to create their own servers within the ARK ecosystem? I understand that ARK is a decentralized platform that promotes interoperability and scalability, but I'm wondering if there's an option for users to set up and manage their own servers for specific purposes or applications. If so, can you elaborate on the process and any requirements that need to be met in order to successfully set up and maintain a private or custom server within the ARK network?
