POL-1401 - New Template: Shared Cost Reallocation - AWS Support

[bryankaraffa]

Description

This policy template reallocates AWS Support costs (OCBPremiumSupport, AWSEnterpriseSupport, AWSSupportBusiness, AWSSupportEnterprise) to the AWS Linked Accounts within the AWS Organization. Costs are allocated to each AWS Linked Account based on the percentage of total that account consumed in the bill period.

To reallocate the costs, the policy template uses Flexera's "Common Bill Ingest" (CBI) capability to negate the original cost allocated to the AWS Master Payer Account with negative cost line items, and write the reallocation portional costs as new line items.

Issues Resolved

Policy Template has console.log() statements. These are used for debugging and should not be present in catalog policy templates

These are false positives from logSample usage... we may want to sync how we want to move forward on this as I think it's something we will want to use in other PTs

[bryankaraffa]

We have 2 customers so far who have deployed this, validated the outcome, and are moving forward with backfilling historical cost data.

Biggest issue we are encountering is policy execution timeout limits (30m) in some of the larger tenants we are testing in. Could be mitigated/prevented by increasing policy timeout limit globally or per-org.

LGTM

Adding "DO-NOT-MERGE" label as per Bryan's comment above. We want to do some more testing potentially on a smaller customer at daily granularity

Other than that, the PR looks good. We may want to consider removing console.logs from the policy template when we are happy and ready to publish to the Catalog
