We use Azure for a variety of services and we are in the process of configuring everything. We use GoDaddy to host our domain, and then we provision from GoDaddy for services such as email. This is one of the things that I just recently configured.
Right now, we're in the process of setting up the firewall. This provides us with security for the website. Firewalls are something that I have a lot of experience with because, in my previous organization, I dealt with audits and other similar tasks that depend on security.
