How many types of servers are there?

Virtual Private Servers: After getting an application up and running on a VPS with ubuntu, what types of issues are likely to occur next?

  • I'm trying to figure out what to read to prepare myself for issues that are likely to occur.  Right now there is only a very small number of users and information in the database (postgres). What types of issues are likely to occur as an application attempts to grow from small to bigger.

  • Answer:

    Database performance, more query means your database process speed will be slowing down. Resource usage, as the time goes, a fully used web apps will accessed by a lot of people and makes a huge resource usage, try to optimize your VPS configuration by replacing some application with a lightweight one, e.g. replace sendmail with postfix, replace openssh with dropbear, replace apache with nginx/lighttpd, etc. I think those two always appears in any growing web apps.

Whether it's shared hosting, VPS or a deicated server, the issues are the same, they just occur ar different points in the lifecycle of the site.  Forget "VPS", forget "Ubuntu" and worry about what's going to happen to your app and your database as usage grows, assuming infinite storage and infinite bandwidth.  (You can always buy more storage and more bandwidth by clicking a box on a form.)  Worry about whether your app and database desin can handle the load it's going to get - you can't change that as easily unless you design for that expansion.
