Managing hosting requires lot of technical skills and experience to deal with server issues, which means that not just customizing the hosting is not enough. An expert IT team is required to handle such server issues. Many clients pick dedicated hosting because it's cheaper than managed hosting. However, if they don't have a dedicated team to manage the dedicated hosting, it gets complicated.
Therefore, If you do not have technical knowledge regarding server setup and management than you should buy Managed Dedicated Server. User can buy or opt for managed dedicated services during order checkout process.
