Need help for a paper

[Gigglemite]

I'm writing a Literature Review (http://www.daniweb.com/techtalkforums/post284895.html#) for my Final project in school and need some expert help for research. I would appreciate any and all feedback if you have the time. Unfortunately, I need this information immediately. If I can use your information, I would like to include your name, title, and company in my paper as a reference...so please provide this information as well. If you don't want to be included as a reference but allow me to quote you, I will add that it's from an anonymous source. Let me know what you prefer. Thanks so much!

Here are my initial questions...

Regarding multiple users, what can you tell me about…
- The system requirements to host multiple users on a web-based application (http://www.daniweb.com/techtalkforums/post284895.html#)
- Multiple logins – concerns to be aware of
- What types of performance issues to expect
- Recommend solution (system (http://www.daniweb.com/techtalkforums/post284895.html#) and/or application if applicable)
- Recommended sites or resources

Regarding real-time updates (http://www.daniweb.com/techtalkforums/post284895.html#) on a web-based application, what can you tell me about…
- The system requirements to host an application like this. Expectation is that it will have versioning capability
- Better to build or buy if integrating in to a custom build web application (http://www.daniweb.com/techtalkforums/post284895.html#)?
- What types of performance issues to expect?
- Recommend solution if applicable
- Recommended sites or resources

Regarding multiple languages on a web-based application, what can you tell me about…
- The system requirements to hosting a site with multiple language capabilities
- What types of things to take into consideration when developing for multiple languages?
- Any performance issues to consider?
- Recommended solution if applicable
- Recommended sites or resources

Unfortunately for most of your questions the answer is "it depends." System requirements is more a factor of traffic and usage than application. A really processor and memory intensive will run just fine of minimal hardware if there's virtually no traffic, and the simplest of web sites can be brought down on a robust server if there's too much traffic for it to handle. That being said, in general complex applications with fairly heavy traffic will probably require a dual processor server. You'll want redundant hardware throughout where ever possible (such as power supplies or network cards) and you'll want hot swappable SCSI drives in a RAID-5 configuration and some kind of automated data backup (write to another drive or perhaps tape, depending on needs).

Making applications work is different languages requires scripting so that everything that appears as text comes out of a language file and that you have placeholders in the code that gets it from the database. For instance you want a color choice of white you would mark the code with something like {address} and when the script found that it would look in the language file for what to put there. If someone were set for German the script would look in the German language file for {address} indirizzo and would replace the marker with indirizzo. This takes minimal server resources to do, so performance isn't really an issue.

Basicly evrything you're asking, if on an adequate server isn't a big deal to accomplish.
