Hi Harikrishna,
you run a HANA only version, thats why your original system had no ABAP stack.
it's possible to "buy" a free ABAP 7.4 on HANA trial license here: https://store.sap.com/sap/cp/ui/resources/store/html/SolutionDetails.html?pid=0000011788
Running this system in the cloud needs lots of ressources, which costs some money. To run your system cost efficent you need to run it on AWS, suspend it, if you don't use it and possibly bid on spot instances: http://aws.amazon.com/en/ec2/spot-instances/
