Using Spot Instances with SAP HANA on AWS Cloud
===================================================================================================================
Update: Nov 16, 2013: I was notified by the SAP CAL Product Owner that using AWS spot instances with SAP CAL software deployed on AWS would be a violation of SAP CAL Developer License Agreement. I have modified this blog to remove all references to SAP CAL. Full details are in my other blog: http://scn.sap.com/community/developer-center/hana/blog/2013/11/17/saps-restrictive-sap-cal-license-agreements

SAP CAL — SAP Cloud Appliance Library
I wrote a blog about using AWS Spot Instances when I took the openSAP class back in May-July 2013.
AWS console has improved since I wrote the above blog — some of the tasks that could only be performed using CLI (Command Line Interface) could now be performed using the console. Hence the need for this blog.
Step I: Create the SAP HANA Developer Edition Instance in AWS:
You may deploy the SAP HANA Developer Edition to AWS from this blog page: http://scn.sap.com/docs/DOC-28294
You will see the Instance below (SAP HANA Server) in AWS.
EBS Volumes:
Step II: Create Images (AMI – Amazon Machine Image):
You may stop the HANA instance before taking the image to reduce your AWS charges.
Step III: Terminate the AWS HANA normal instance:
This will stop AWS from charging for the instances and associated EBS Volumes.
Step IV: Create Spot Instances:
You can create a new key pair, if you don’t have one already for the step below.
Display EBS volumes and take a screenshot of the page and save it — this is needed later in Step VIII.
Step V: Allocate and Assign Elastic IP for the Spot Instances:

Useful one. Some pics are not visible. Please try to fix it from your end.
Raman, Fixed the images by adding a continuation blog. Thanks.
Hi Mani,
very good blog, esp for us, end users. just out of curiosity, will you be providing the final check for the connection between the two AWS instances when they are brought back through the Amazon rather than CAL? for some reason, i'm not sure if the newly created key pairs (as you are describing them in step IV) guarantee a successful connection between the HANA server and client.
thx again for writing this up.
rgds,

Greg,
Thanks. It appears using spot instances with AWS Instances deployed through SAP CAL may be a violation of SAP CAL Developer License agreement. Full details are here: http://scn.sap.com/community/developer-center/hana/blog/2013/11/17/saps-restrictive-sap-cal-license-agreements
However, if you have any specific questions about how to connect to AWS spot instances -- created from HANA Dev Center (http://scn.sap.com/docs/DOC-28294) -- from HANA studio on your PC or from HANA Studio deployed on another AWS instance, please send me a private message through SCN or openSAP. I may write another blog or update this blog with this info at a later date.
Thanks.
What will be exact ( i mean near exact) savings if I create spot instance / normal instance and use it for 3 hour /week ( in 2 intervals ) over one month period.
assume using m3.medium and r3.2xlarge.
Is it worth to take trouble of Termination vs Suspend
Thanks in Advance
Well explained .... Great.
Mani saved Money ....Perhaps adding all penny saved might be greater than million..
Ohh.. I didn't notice the violation part ...Thanks for keeping us ethically right...
