Is it possible to deploy SharePoint solution (WSPs) via feature activation?

this seems to me an uphill task in SharePoint but is it possible to deploy the WSPs via SharePoint features. For instance, if we activate a certain feature then some specific SharePoint s开发者_运维知识库olutions (WSPs) should be deployed on SharePoint farm.

Yes.

You need to get a reference to the solution object itself via SPFarm.Solutions.

Once you have the SPSolution object, call Deploy (SPSolution.Deploy()) to deploy it.
