+# Open source cost monitoring for cloud native environments
+
+OpenCost is a vendor-neutral open source project for measuring and allocating 
+infrastructure and container costs in real time. Built by Kubernetes experts and 
+supported by Kubernetes practitioners, OpenCost shines a light into the black 
+box of Kubernetes spend.
+
+
+### Goal
+
+> OpenCost is a tool or monitoring the cost of Kubernetes. 
+In a world of horizontal pod autoscalers and autoscaling node groups 
+it is important to be able to monitor and perhaps even regulate spend automatically. 
+The obvious possibility of OpenCost is integrating with Prometheus and 
+using Prometheus to create cost alerts. Another possibility 
+I see is integrating OpenCost metrics with custom metrics 
+for horizontal pod autoscalers in Kubernetes as a way to set limits on spend 
+when scaling automatically. The autoscaling/v2 API supports scaling based on 
+multiple metrics. By leveraging custom metrics constraints on scaling can be set 
+based on data from OpenCost.
