Hi @nadipalli_sai , AEM is a licensed software. If you want to try it,
then your company should be Adobe's Solution partner. You can sign up
for Adobe's Solution partner program to get access to Adobe's learning
resources, trainings & certifications, trial software etc. You can check

Hope this helps. Thanks,Hema
