What's the term of manage and expost web applications like SharePoint

Ruffly Speaking, I want to know the name of the feature which Microsoft SharePoint provides that the ablility to manage many web applications and ex开发者_StackOverflowpose them as web parts.

I'll try to explane more, from wikipedia:

Microsoft SharePoint is a software platform provides collaboration, Web content management, documents management, enterprise search, Web 2.0 features, and many other features under a single platform.

What I understand from that that it's a collection of features provided in a single system, I would like to search about a software platform similar to SharePoint able to manage many web applications and expose them or provides them as web parts but I don't know the search keywords which I have to look for.

Look for the keyword “Portal”.
