Cost Insights

Cost Insights is a plugin to help engineers visualize, understand and optimize their cloud costs. The Cost Insights page shows daily cost data for a team, trends over time, and comparisons with the business metrics you care about.

At Spotify, we find that cloud costs are optimized organically when:

Engineers see cost data in their daily work (that is, in Backstage).
It's clear when cloud costs need attention.
The data is shown in software terms familiar to them.
Alerts and recommendations are targeted and actionable.

Cost Insights shows trends over time, at the granularity of Backstage catalog entities - rather than the cloud provider's concepts. It can be used to troubleshoot cost anomalies, and promote cost-saving infrastructure migrations.

Install

yarn add @backstage/plugin-cost-insights

Setup

Configure app-config.yaml. See Configuration.
Create a CostInsights client. Clients must implement the CostInsightsApi interface. See the API file for required methods and documentation.

// path/to/CostInsightsClient.ts
import { CostInsightsApi } from '@backstage/plugin-cost-insights';

export class CostInsightsClient implements CostInsightsApi { ... }

Import the client and the CostInsights plugin API to your Backstage instance.

// packages/app/src/api.ts
import { createApiFactory } from '@backstage/core';
import { costInsightsApiRef } from '@backstage/plugin-cost-insights';
import { CostInsightsClient } from './path/to/file';

export const apis = [
  createApiFactory({
    api: costInsightsApiRef,
    deps: {},
    factory: () => new CostInsightsClient(),
  }),
];

Add cost-insights to your Backstage plugins.

// packages/app/src/plugins.ts
export { plugin as CostInsights } from '@backstage/plugin-cost-insights';

Configuration

Cost Insights has only two required configuration fields: a map of cloud products for showing cost breakdowns and engineerCost - the average yearly cost of an engineer including benefits. Products must be defined as keys on the products field.

You can optionally supply a product icon to display in Cost Insights navigation. See the type file for supported types and Material UI icon mappings.

Note: Product keys should be unique and camelCased. Backstage does not support underscores in configuration keys.

Basic

## ./app-config.yaml
costInsights:
  engineerCost: 200000
  products:
    productA:
      name: Some Cloud Product ## required
      icon: storage
    productB:
      name: Some Other Cloud Product
      icon: data

Metrics (Optional)

In the Cost Overview panel, users can choose from a dropdown of business metrics to see costs as they relate to a metric, such as daily active users. Metrics must be defined as keys on the metrics field. A user-friendly name is required. Metrics will be provided to the getDailyCost and getProjectCosts API methods via the metric parameter.

Note: Cost Insights displays daily cost without a metric by default. The dropdown text for this default can be overridden by assigning it a value on the dailyCost field.
