I have a question. After a webapp development finished, how to deploy it, and let others use it.

Can i deploy it to my own tomcat service? How to do with this?

Anyone can help me? Thank you. 

Hi Yongjin,

I think we need more details about what you want to do.
OutSystems deploy application between servers with LifeTime.

Basically, you have 3 default environments. Development, Quality, Production.
After you completed the development stage you can publish your application to QA then Live with LifeTime.

Here is the official document about Infrastructure
