Supported Clouds & Services

KOSTRA connects to the major cloud providers and treats each as a first-class source of cost and resource data. Its differentiator is breadth: KOSTRA supports more providers than most FinOps tools, so a diverse estate is managed as one. This page describes what is covered today and what is on the roadmap.

Where many tools stop at the three largest providers, KOSTRA adds Huawei Cloud with genuine depth — resource discovery, billing, and provider-specific recommendations — so an estate that includes it is covered by the same platform as everything else.

Huawei Cloud service matrix

Because Huawei Cloud is the provider most often missing from other FinOps tools, its coverage is worth detailing. KOSTRA discovers Huawei Cloud resources through the official SDKs, imports spend from the BSS billing service, and reads Cloud Eye (CES) metrics where rightsizing requires utilization data.

EVS (Elastic Volume Service)Volume and snapshot discovery, billing, unattached-volume and obsolete-snapshot recommendationsShipping

IMS (Image Management Service)Image discovery, billingShipping
NAT GatewayCost tracking via billingShipping (billing); resource discovery on roadmap
CCE (Cloud Container Engine)Cost categorization via billingRoadmap for resource discovery
DCS (Distributed Cache Service)—Roadmap
For reseller and partner accounts where billing suppresses line-item amounts, KOSTRA can derive a synthetic bill from discovered resources and on-demand rating, so cost visibility is preserved even when the billing feed is incomplete.

​
Recommendations across your estate

More than a dozen recommendation modules run across your connected accounts — abandoned instances, unattached volumes, obsolete snapshots, idle IPs, abandoned load balancers, abandoned object-storage buckets, database rightsizing, instance rightsizing and migration, reserved-instance opportunities, and insecure security-group checks. They run on the same schedule and appear in the same experience for every provider, so a team sees its opportunities regardless of which cloud a resource lives on.

​
A note on roadmap items

Where a service is marked “roadmap,” KOSTRA does not yet discover it as a resource, and you should not assume resource-level coverage until it ships. Cost billed under those services still appears in your spend totals through billing ingestion; the roadmap work adds resource discovery and service-specific recommendations on top.
