I’ve been using this tiny 64MB vps for quite some time now, and with much tweaking was able to run the basic LAMP stack (apache, mysql, php) with mail on many domains, but there was no room for future growth. With all these services it was difficult to serve many concurrent users. So I decided to change VPS providers to increase the resources on this system. The transition went smooth. All services transferred without interruptions.
The good thing is this VPS has 384MB of ram. After being restricted by such a small amount of ram for so long it is nice to have plenty of extra resources. Now that the transition is complete, I can continue working on some custom services.
