Calculation of On-Premises and SaaS Infrastructure Costs

The breakdown below shows how the above infrastructure costs are calculated for both on-premises and SaaS infrastructure.

For SaaS, the on-premises performance repository is not needed because the data is stored in the cloud. The cost associated with Cloud Data Storage and Analytics is included in the Saas Year 1-3 Subscription cost.

Assumptions

  • Server Pricing

    Server price estimates are based on an average specification DELL poweredge server with Windows Server installed.

  • Storage Pricing

    For Storage costs Wasabi.com estimates the fully loaded costs of on premise storage over three years to be $32 per month (or $1152 over 3 years). For this exercise, we will assume an extremely friendly IS department who allow us a mere $12 per month ($360 over 3 years). For more detail on this estimate, you may read: Does it Pay to Move from On-Premises to Public Cloud Storage?

  • Storage Volumes

    On Premise monitoring systems generally have two repositories:


    A Diagnostics repository collects very detailed metrics - some collected every second. Generally, these retain between one week and one months history.


    A reporting/analytics repository which retains history for longer periods. Depending on the specific solution, this data may be an aggregated version of the diagnostics data. With SaaS solutions the SaaS vendor manages the repositories. Because the SaaS vendor has access to cloud storage and cloud compute they tend to support longer retention periods and more sophisticated cubing of data for analytics. For a more detailed discussion on architecture, check out: Database Monitoring System Architecture Blog.

  • SQL Server Licencsing

    At the time of the coding of this tool, SQL Server 2017 Standard edition was priced at US $1,859 per core (sold in a 2 core pack). We assume SQL Server as the back end repository for performance data.


Limitations

  • For simplicity, many on premise costs are understated.
  • Server costing is based on a crude assessment of an average server.
  • SQL server licensing assumes standard edition. For very large environments, enterprise may be favorable.
  • In larger environments, multiple data collectors would be deployed. Numbers of monitored connections vary per vendor.
  • For this exercise, only one data collector is specified.
  • Similarly, for large environments, it may be desirable to split the diagnostics and analytics repositories. This will depend on the vendor architecture. No on premise fail over is factored in the above estimations.
  • Subscription pricing assumes a price per monitored connection as opposed to a pricing structure based on stored performance data.
