Magento Cloud infrastructure -- 2

i have a cloud infrastructure, with a Magento ecommerce website. Infrastructure is loadbalance -> 2 x nginx/php vm -> 1vm as nfs -> 2 x perconadb cluster -> 1x redis cache. everything is woking ([login to view URL], [login to view URL] and someothers) but i need to do some changes: 1) move magento admin panel to a dedicated vm 2) create a second redis instance and make it listen on a different port 3) export via nfs only magento/media, rest of the magento folder structure should be synced with [login to view URL]
