On premise mapped to AWS

A question that often comes up when companies are migrating Oracle workloads to AWS is: "How do my on premise IT architecture components map to AWS?".  Here are some of the most common components mapping from on premise to AWS:

Oracle OEL AMIs running on cluster compute instances

AWS cluster compute instances types (cc1.4xlarge,cg1.4xlarge, cr1.8xlarge, cc2.8xlarge), all require to be run as HVM instances.  Currently, all the AMIs from Oracle are PVM only. Windows EC2 instances can only be HVM as PV does not support windows, so Windows AMIs or HVM based Linux AMIs can be used.

OVM based Oracle AMIs can also not be run on cluster compute instance types.

Oracle on AWS costs of Oracle on AWS and licensing management

Here are two common questions in regards to Oracle pricing and licensing on AWS:

1. How can they determine the pricing for an instance launched from an Oracle AMI e.g. https://aws.amazon.com/amis/oracle-database-11g-release-2-11-2-0-1-enterprise-edition-64-bit?

The bottom line: The pricing are the standard EC2, data out traffic, and storage + cost of Oracle licenses (or no cost of Oracle licenses if they have their own)

2. How do they manage BYOL or using unused licenses in practical terms? (afaik they have to BYOL for Oracle on EC2)

The bottom line : It is up to the customer to make sure they are not violating Oracle licensing policies.

AWS three top services that contribute to pricing

Typically the top three AWS services that contribute to the price of AWS services are:
1.  Compute (typically EC2)
2.  Storage (typically EBS or S3)
3.  Data transfer out
