The best features Firefly offers include cost saving and drift detection, which native infrastructure as code solutions do not provide. Drift detection and governance are great features for Firefly that help me identify unutilized resources that can save costs. Firefly's drift detection and governance help me day-to-day by notifying me of any configuration drifts, such as when developers change configurations that I cannot control. For example, if I have a number of VMs running and their configurations are changed, Firefly alerts me to these changes, allowing me to identify gaps in configurations that can be corrected. Firefly's accuracy and reliability in output are impressive, with approximately 80% accuracy in building the required code for various services from the foundation services like EKS and VPC. Firefly has positively impacted my organization mainly through cost savings and governance. It allows me to have a centralized dashboard for a complete view of my AWS accounts to find problems easily. Additionally, it has saved me time because I no longer need to write every Terraform from scratch, as Firefly provides best industry practices code. For example, I monitored my database instances and found that someone had expanded the ACU size from the required number to ten times more, which began costing me $10,000 monthly extra for one AWS account. Firefly detected this and saved me the $10,000 extra expenditure.
