During the pandemic, Companies have made a major shift toward cloud investments.. Until a few years ago, all internal applications, including finance-related applications, were hosted on on-premise servers. These on-prem servers have fixed capacity and cost.  Any changes to these On-prem server configurations required buy-in from the tech team as well as the finance teams and CFO. However, since the introduction of cloud computing, the cloud cost has become a variable of the processing/data load. The finance teams’ visibility of cloud costs and their prediction has dramatically decreased. Finance teams have been struggling to adjust to this new normal. This is attributable to a number of causes, including

  1. Lack of accountability 
  2. Lack of  controls
  3. Finance teams traditional processes of forecasting

Engineering teams can enable accountability and control by using  various cloud-ops tools. These tools bring standardization and governance to cloud capacity building. Finance teams should be made part of the this governance and approval process.

Bringing all of the above-mentioned data points together and modeling them in Excel is a massive undertaking in itself. This is where financial teams may benefit from machine learning. Machine learning can take into account previous costs as well as factors such as server loads, new projects, and so on.
