1.2 Identify aspects of AWS Cloud Economics
Define items that would be part of a Total Cost of Ownership proposal
- Understand the role of operational expenses (OpEx) – building and maintaining infrastructure, data centers, updates and patches, security
- Understand the role of capital expenses (CapEx) – buying equipment, space, licenses
- Understand the labor costs associated with on-premises operations – keeping engineers, architects, and administrators on staff; spending work hours on infrastructure upkeep rather than development
-
Understand the impact of software licensing costs when moving to the cloud
- License compliance during migration to AWS
- Users can substantially reduce costs by using existing licenses
- AWS License Manager provides a mechanism to allocate licenses to both your on-premises and cloud-hosted resources and allows you to automate the tracking of how these licenses are consumed
- Users must monitor their own licenses and ensure compliance with licensing agreements
Identify which operations will reduce costs by moving to the cloud
- Right-sized infrastructure – match resource provisioning to usage needs
- Benefits of automation – increase efficiency by automating many aspects of cloud infrastructure, deployment, and monitoring
- Reduce compliance scope (for example, reporting) - automated services make it easier to maintain logs and reports for auditing
- Managed services – AWS handles updates and maintenance instead of the customer
