Is the Akash Network decentralized?

Could you please enlighten me on the nature of the Akash Network? Specifically, I'm curious to know if it's decentralized? If so, how does it achieve this decentralization? Also, what are the benefits of a decentralized Akash Network? Could you elaborate on its structure and operations in this regard? Additionally, how does decentralization impact the security and scalability of the network? I'm keen to understand its implications on the overall functionality and reliability of the Akash Network. Thank you for your insights.
