Thank you for your info. Please refer our SOW&BOM in the attachment. For this solution, I have considered about adding and Additional domain controller in the SOW that you can see in item no.3 in the Statement of work portion. You can remove if need. If you have any question or any change is needed, please feel free to contact me.
By the way, Database software for application servers will not be show in a part of BOM due to we have no info for this portion.
