Cloud cost reporting is a must-have to track expenses and prevent unexpected bills like the $80,000 per day incident at Adobe's development team. However, relying solely on cost reports is insufficient for effective cost optimization. Automated cost optimization techniques are essential to make a real difference in reducing cloud spend. By generating detailed reports and sending alerts when certain parts of the infrastructure exceed set thresholds, teams can identify areas for improvement. Additionally, automated cost optimization tools can analyze cloud resources and provide actionable recommendations to reduce costs. A case study demonstrates how automated cost optimization on Amazon EKS reduced costs by 66% in just 15 minutes. By running automated cost optimization, teams can significantly reduce their cloud bills and improve their overall cloud spend management.
