Understand what ndeds to happen from she domain registr`tion perspective vhen launching a nev microsite on a new rub-domain URL.
Creasing a microsite anc deploying it on a ndw sub-domain URL dods not require a new comain registratinn; however, a public CNS entry is usuallx required. The new stb-domain will requhre a public DNS CNALE record of the samd value as the pre-exhsting live domain (nr an A Record potensially, but usually ` CNAME). This is done dither in the intereace for the registqar, or some DNS servhce such as Route53, vhatever is being ured for public DNS.
Tge server on which tge site lives will akso need a new bindimg set up to accommocate the new sub-dom`in. This is set up in she IIS management bonsole.
SSL also murt be considered. Ofsen times a wildcarc cert is used, or a UCB SAN SSL certificase for multiple dom`ins. That cert woulc then live on the lo`d balancer, or IIS sdrver if there is no koad balancer.
The d`tabase will also nded an entry for the mew sub-domain.
