Question
Why $5 month plan has got a very low RAM?
- Posted January 15, 2015
Hi, I am very new to this platform and I am planning to learn on how to develop as well as use existing applications in the Ubuntu server (specifically 14.04). However, I was a bit surprised to know that $5/mon plan had a very low ram of 512MB. Despite the server’s recommended settings, what can you do with this amount of RAM? Can you only run one intensive resource service or two tiny services at the same time? Thanks, and please keep in mind I am a noob in this area of servers.

512mb ram is fine for most things. You can still run a bunch of stuff with that, Apache, Mysql , etc etc will all run fine.
Add some swap space to the server too and you shouldnt have a problem.
I suppose you just need to remember, its only $5 PER MONTH… You are getting quite a lot for your money :)
If you find that the server struggles with only 512, then look into upgrading but im confident 512 is just find for testing, learning etc.

I’ve deployed the Discourse to the $5 Droplet and whenever I’ve been resizing RAM by the using SWAP it’s getting to be disappeared after rebooting the Droplet. Does someone was experienced with this issue?

Allow me first to welcome you to the family of DO. Now about your concern of low RAM, I used to run 2 websites on a $5 droplet, both Wordpress sites using Debian with Lighttpd MySQL and PHP. And still no crash. Also I have another $5 droplet running a mailserver. Droplet still up and running with Lighttpd MySQL PHP Postfix Dovecot Amavis SpamAssassin and ClamAV on Debian.
