The User Profile Synchronization service is the core of the synchronization architecture in SharePoint Server 2013. When you start the User Profile Synchronization service on the synchronization server, SharePoint Server 2013 provisions a version of Microsoft Forefront Identity Manager (FIM) to participate in synchronization. A User Profile service application can only have one User Profile Synchronization service. A User Profile Synchronization service is associated with connections and mappings.
Plan profile synchronization for SharePoint Server 2013
Profile synchronization (also known as "profile sync") allows you to create user profiles by importing information from other systems that are used in your organization.
You can only run one instance of the User Profile Synchronization service on a farm,The computer on which the User Profile Synchronization service runs is called the synchronization
You specify the synchronization server when you create the User Profile service application. SharePoint Server provisions a version of Microsoft Forefront Identity Manager (FIM) on this computer to participate in synchronization.
When you create the User Profile service application, you can specify the synchronization server (also known as the profile synchronization instance), which is the computer that will be used to synchronize profile information. Creating the User Profile service application creates several databases, such as the profile database.
Important consideration to guarantee successful setup for User Profile Synchronization service
Note: After making changes to the farm account, e.g. add admin to administrators (make sure to restart the timer service or restart the server) in order for this change to take effect.
Now after setting all of the above you can start the User Profile Synchronization Service which might display the status of Starting. When you start the User Profile synchronization service, SharePoint Server provisions FIM to participate in synchronization. This may take 10 minutes.
Missing one of the above might cause one of the two below behaviors:

Finally, I do see this. Clearly explained. Well done. Thanks
"You specify the synchronization server when you create the User Profile service application. SharePoint Server provisions a version of Microsoft Forefront Identity Manager (FIM) on this computer to participate in synchronization."
Does this require FIM to be separately licensed?
im not a licensing specialist but as far as i know this piece of FIM functionality comes as part of SHarePoint license
Issa - Your statement "You can only run one instance of the User Profile Synchronization service on a farm...", is not correct. You can have multiple UPS in a Farm, but only one UPS service can run on 1 SharePoint server, i.e., if you have 3 servers in the farm, you can run 3 seperate UPS's if you need to. We have multiple UPSs/UPAs setup on our Farm due to the various authentication methods we have deployed. That is in SP2010, unless things have changed in SP2013. Thanks.
hi Neeraj ,
thanks for your comment , however this is not my statement this is our statement as Microsoft which you can find it in one of the references i included in this blog technet.microsoft.com/.../ff182925.aspx
search for the same wording and i hope you will get it right in there :)).
however if you refer to my blog above you can see a screen shot for selecting Profile Sychronization instance , the the drop down will not allow you to select more than one server in there
How can I stop sync if one of the sources BDC is offline?
Why you said "MySite should be setup before starting the synchronization service"? Thanks.
Thanks for this good explanation.Faisal Masoodhttp://www.FaisalMasood.com
Hi Issa,In my setup, I am not able to see User Profiles. I can see only User Profile Service Application and my properties tab is grayed out. Do you know why is it like that?Thanks in advance!
After doing everything you said, I am still unable to start the user profile service Application
Great article ...Thanks for your great information, the contents are quiet interesting. I will be waiting for your next post.
