I think there's nothing as Dataguard is SQL Server but some features only.
Are you searching for some specific feature?

Basically we are looking for high availability, currently using SVC to achieve this HA, this is the primary goal that if by any reason our Primary goes  down, how fast we can be up & running on the secondary db/location or whatever we can achieve, in the fastest and best possible manner.

We are currently in the process of evaluating and come up with the best possible options for our scenario.

I think you are looking for Always On Availability Groups, which exists in 2012 and onward. For 2008r2, you want a failover cluster. See this page for a walkthrough

If you are only looking for HA feature then as mankowitz wrote, the answer is AlwaysOn but don't exist on you SQL Server version. Problem with failover cluster is that you'll lose connection during the failover and there's no secondary database for you connect as read-only for reporting purposes for example.
