We had an old school type of DR with replication. 

Since we put CloudEndure in place, which is our DR for our Tier 1 and 2 servers, replicating out from our facility to AWS, and it has been bare-metal to bare-metal type of disaster recovery. This is our first cloud-based DR solution.

This is the first solution we are using in the cloud. In the datacenters there are other solutions used, but this is the first time we are using a DR solution in the AWS cloud.

Our group did not use a different solution, but our data center had a different solution. When we went to AWS, the data center people were not able to support us with a disaster recovery solution, so we looked and chose CloudEndure.

We tried a native solution from Rackspace but it failed.

I have worked with many different vendors and the choice of solution depends on the customer's requirements.
