Should I turn off swap on AWS EC2?

I'm running a webserver and database server on the same AWS EC2 instance. I know it's a bad idea to have swap for web server, so should I just turn it off? Will it affect the database service (I guess not but I'm not sure on this). If yes, how do I turn it off?

I'm running Amazon Linux AMI.

Thanks ;-).

However, sometimes there are odd circumstances. Where did you get the information that it is bad idea to have swap for web server?

Also, this is wrong information that you have:
