Instance Operations: SAP Cloud Appliance vs Amazon Web Services
I recently deployed a SAP HANA SP6 appliance for the openSAP course as described in this blog http://scn.sap.com/docs/DOC-47930.
I have listed below the operations that can be performed in SAP Cloud Appliance Library (CAL) Solutions/Instances and their AWS (Amazon Web Services) equivalents.
|Instance — may contain one or more Virtual Machines (VMs)||Instance contains only one VM|
|Public Network||Instance created in EC2 (Elastic Compute Cloud)|
|Corporate Network||Instance created in VPC (Virtual Private Cloud)|
If you need more info about Private and Corporate Networks, you may refer to these blogs:
Instance Operations comparison:
This below table applies to AWS EC2 (not VPC).
|SAP CAL Instance Operation||Operations/Commands executed in AWS|
|Back Up||Create AMI (Amazon Machine Image).|
|Restore||There is no single command for this. It appears EBS volumes are created from EBS Snapshots, instance is stopped, original EBS volumes are detached, and the new EBS volumes are attached.|
Note: Back Up is not possible for Appliances with more than one Virtual Machine (VM) like the openSAP HANA SP6 Appliance which has two VMs.
What would be the CAL equivalent of the AWS' spot bid (of the Back Up/AMI)?
There seems to be no equivalent at the moment. I plan on writing a blog -- rather updating my blog (http://scn.sap.com/community/developer-center/hana/blog/2013/06/23/preventing-the-deletion-of-ebs-volumes-during-the-termination-of-aws-spot-instances) -- about using spot instances with SAP HANA on AWS Cloud in a week or so.
