VPS - 1GB RAM enough for Web Server?

Hi All


I want to buy/rent a very affordable VPS package at my ISP. Now it comes with the following:

• 1GB RAM
• 10GB Traffic
• 10GB Disk Space
• 1 vCPU
• Ubuntu or CentOS

Now my requirements are:

• Surfing internet
• Hosting a small to medium website (less than 1GB traffic a month)
• DNS server
• LAMP - Apache, MySQL and PHP
• All have to run concurrently

Now my question - Is 1GB of RAM sufficient to do all this? Remember this is a Virtual Environment running on either Ubuntu or CentOS.



Also, what do you recommend - Ubuntu or CentOS?
