Best approach for department separation

[ebuild]

I have a requirement where I need to create in one Alfresco instance spaces by department designation,
is this possible by using permissions and group or there is more dedicated feature ?

You can use the site's feature of Alfresco to achieve what you need.
A site is intended to be used just like you need.
