Elaboration of Executive Presentation of Infrastructure costs for an SAP Migration project from On-Premises to AWS
In this project based on a real-world scenario, I acted as a Cloud Architect and created an executive presentation of infrastructure costs for a SAP migration project from On-Premises to AWS.
SAP workloads were running in a corporate DataCenter with the environment divided into Production, Quality Assurance — QA and Development/Test layers.
I had assumed that the cost of moving from on-premises to cloud infrastructure would be exponentially higher than that of traditional hardware and software. I was taken aback by the reality, which defies common sense. How could an environment that operates at lightning speed and is technologically improved by quantum leaps be less expensive than a standard legacy on-premise setup? The lower cost is, in my opinion, one of the key advantages of employing a cloud environment over an on-premises data center.

We’ll need of 3 TB = 3000GB / 2 = 1500 GB per instance
Estimate cost for Oracle Database: “HML”

Estimate summary:
My mission was to estimate the costs of migration to AWS, considering that this infrastructure will be running on AWS for at least the next 3 years. Using the AWS Pricing Calculator, I was able to generate a cost estimate for migrating each of the three SAP environments to AWS. I then exported the cost estimate to an excel document. The cost were broken down into monthly and annual cost. I then imported that data into and executive cost presentation in order to present the cost estimate in a visual and easy to understand format.
Monthly cost cal:

Total Cost 12 Month(USD)
Conclusion: An essential step in the cloud migration process is figuring out how much it will cost to migrate to the cloud. The AWS Pricing Calculator offers a precise cost estimate for moving on-premises resources to the cloud, making it an invaluable tool for cloud professionals.
