Connect AWS, Azure, or Google Cloud

KOSTRA is multi-cloud by design. You can connect AWS, Azure, Google Cloud, and Huawei Cloud so that every provider feeds the same cost model, recommendations, and governance workflows. This guide covers the shared flow and what each of these providers needs.

​
The shared connection flow

Every provider follows the same path in KOSTRA:
  1. In the left navigation, open Data Sources.
  2. Select Connect data source.
  3. Choose the provider.
  4. Enter a name for the data source.
  5. Provide the provider-specific credentials described below.
  6. Select Connect.
KOSTRA validates the credentials during connection and, once accepted, schedules the first billing import and resource discovery. As with Huawei Cloud, the credentials only need to read billing and describe resources — avoid using administrator keys.

​
What each provider needs

​
AWS

Connect an AWS account using an access key with permission to read your Cost and Usage data and to describe resources. KOSTRA supports connecting a management (payer) account for organization-wide billing as well as individual member accounts. Point KOSTRA at the billing data location you have configured for cost reporting.

​
Azure

Connect an Azure subscription with credentials that can read consumption and usage data and enumerate resources. KOSTRA reads subscription-level spend and discovers resources across the subscription.

​
Google Cloud

Connect a Google Cloud project using a service account key with access to your billing export dataset and permission to describe resources. KOSTRA reads the exported billing data and discovers project resources. For the exact permissions and billing-export settings each provider expects in your environment, follow the in-product prompts on the connection form, which reflect the current requirements.

​
After connecting

Once an account is connected, KOSTRA treats it identically to every other provider:
  • Cost Explorer shows its spend alongside Huawei Cloud and any other connected accounts.
  • Recommendations evaluates it against the optimization catalog.
  • Pools and Allocation Rules let you attribute its spend to teams and business units.
Because all providers land in one normalized cost model, you get a single, comparable view across your estate rather than four separate consoles.

​
Multi-cloud in one view

Connect your accounts in any order, and add more as your estate requires. Each additional account widens the picture without changing how you work: the same dashboards, the same recommendation experience, the same chargeback rules apply across all of them — including on Huawei Cloud, which many other tools cannot cover at all.

​
Verify the connection

For any provider, confirm success the same way:
  1. Check that the account shows a recent successful import on the Data Sources page.
  2. Open Cost Explorer to see spend appear as imports complete.
  3. Open Resources to confirm discovered resources are listed.
Allow a full scheduling cycle for the first complete data set, and expect recommendations after the first optimization run.
