The approximate TCO for the Dell EMC VxRail on-premises solution was a minimum of 30% (with the potential for more) over three years with more features and performance benefits guaranteed.
Beyond TCO, the VxRail platform provides:
- Single cluster and simple management
- Easy updates; all updates (firmware, drivers, SW) with simple qualified clicks
- Single pane of glass management
- 25 GB networking (compared to 10 GB from AWS)
- Latency consistent with current on-premises experiences (compared with unknown latency from Direct Connect)
- AWS TCO white papers do not estimate any form of network costs, which tend to be high and equivocally cited in high volume workloads such as HANA databases.
- In this TCO calculation, we assume the need of direct connect data transfer at a lower end of the spectrum. However, depending on customer’s need and application characteristics, data transfer costs could require a higher bandwidth connection which may further increase the AWS solution costs.
- The Inter-AZ traffic volume due to high availability scenarios can create a peculiar impact, where customers are cognizant of volume or velocity of Inter-AZ data transfer.
- AWS does not offer a choice of a 1.5 TB RAM instance. In this case, the customer must overprovision resources that they are not supposed to and is an extra cost to the customer.
- Depending on customer’s backup and recovery strategy, storage costs can also impact the operational budgets.
- This TCO has backups that align to a standard performance tier of Elastic File System (EFS) service (networked file system).
- The EFS costs can significantly impact the operational budget when moving to Provisioned Throughput mode. Also, the customer must keep a tight check on backup volume or frequency to avoid overwhelming associated costs with cloud TCO.
- EFS pricing can create cost complexities that impact customers as shown in the Amazon Elastic File System (EFS) Cloud File Storage Pricing page (scroll to the Pricing table).
