Hi
I am a system and network administrator, with more than 10+ years of experience.
During that period I have installed, administrate and maintain a large number of various servers, such as Web Server (Apache, IIS), Mail Server (Postfix, Exim, MS Exchange), DNS Server (BIND, Unbound, MS DNS), etc., based on, FreeBSD, CentOS, RHEL, etc.
As for the project, do you have EC2 instance deployed? Also, do you have DNS configured?
Looking forward to hearing from you soon.
