While engineering teams consume cloud resources without considering cost-efficiency, finance teams struggle to keep up with these expenses, leading to wasted budgets and unnecessary costs. Enterprises often underestimate their cloud spend due to overprovisioning, skills shortages, outages, and inadequate budgeting and forecasting. To address these challenges, it's essential to implement automated cost optimization solutions that provide real-time insights, reduce errors, and increase savings. By leveraging tools like AWS Cost Explorer, Microsoft Azure Cloud cost management, Google Cloud Billing, and CAST AI, organizations can streamline their cloud cost management strategy, eliminate expensive mistakes, and ensure business continuity in the face of vendor outages or changes in demand.
