By profession I am Linux System and Security Engineer and love to do geeky things love to hack vulnerable machines.I love to play with Cloud , Mysql , Load Balancers , Nginx , Linux , Linux Security and also a Python and Shell beginner.

My Manifesto:-

Yes, I am criminal. My crime is that of curiosity. My crime is that of judging people by what they say and think, not what they look like. My crime is that of outsmarting you, something that you will never forgive me for. I am hacker, and this is my manifesto. You may stop this individual, but you can't stop us all...

comment how to change domain name in aws?
So so many free DNS services are available like dnsexit.com , register on them and add ur domain there and create a hostname recors (A record) for your subdomian pointing to your IP of aws server., I would recommend add Elastic IP to your box instead of using Dynamic Public DNS .

comment How should I use EC2 ? One instance per application or one for all my architecture
It depends upon how busy your each app is? If you have a low traffic app than yes you can go for single instance but my concern with this is you are in cloud and at higher risk of getting some technical glitch , what you can do is benchmark your apps with single instance and also with splitting them on multiple instances.

Why not add CNAME Alias for your domain which will point to OADBALANCERDNSNAME.ap-southeast-1.elb.amazonaws.com?

So putting a single box behind LB is not of any use , atleast put more than one box behind LB so that you can scale your app , and put each instance in different zone so that you will get redundant architecture.
