Automatic sync of G Suit groups to Atlassian Admin

[Rajnish Dahiya]

G Suit is our primary user organization. We have lot of groups there to manage permissions etc easily. Then we are syncing G suit users to Atlassian Organization. But Google groups are not reflecting in Atlassian Admin, I see only 1 group with all  the G suit users in it "All users from G Suite". We need same grouping in Atlassian so we can grant group wise permissions for various products (Jira, Confluence, BitBucket at the moment). Obviously we don't want to go through the painful process of creating groups again in Atlassian and then maintaining then in sync manually.
I see there is something called "Atlassian Access" which seems to be providing this feature and much more I guess. https://support.atlassian.com/provisioning-users/docs/set-up-g-suite/

I see there are some SAML SSO plugins doing same thing and I guess bit more.

I am not sure which one is most suitable for us. (we get what we want in lowest cost)
