To ensure that employees make informed but flexible decisions when managing data infrastructure costs, Netflix developed a data efficiency dashboard to surface cost and usage trends and provide visibility into these costs by data resource and/or team. For EC2 based platforms, Netflix calculates cost using bottleneck metrics (e.g. CPU, memory) per resource, while for S3-based platforms, Netflix calculates the cost based on storage bytes per data resource. The cost data is surfaced through a druid-backed custom dashboard. This platform also provides recommendations on the optimal duration of storage and can clean up older datasets.
