Cuba Architecture

Hello Team,

Related to Cuba architecture is not quite clear for me how are made the main tiers:

User Interface (descriptors and controllers) running on separate servlet (Tomcat ? Jetty? why?)
and
Middleware (business logic - spring bean) running on a separate servlet (Tomcat? Jetty? why?)
Maybe you can provide more details, please (apart of Application Tiers and Blocks - CUBA Platform. Developer’s Manual )

Regards,

Hi,

It was done for the sake of scalability. I’d suggest to have a look at the corresponding documentations section, hope that will help you to understand what’s going on.

Hi,
Ok, now is pretty much clear.Every module could be deployed based on a Tomcat App Server.
However when I run the project in Idea I saw that a Jetty server starts. What is the story with this server?

We run Jetty in IDEA to serve some CUBA Studio plugin internal processes, it doesn’t rely to application deployment.

But we use Jetty when you deploy the app as an UberJar - runnable Jar file that does not need to be deployed to Tomcat or other app server. In fact, every UberJar has a Jetty app server packed into it and CUBA app is deployed to Jetty.

Okay, good to know.
Thank you!
