Policy Exclusions
1. Introduction
With the help of Policy Exclusion feature, users of the CoreStack platform can exclude specific resources from recommendation listings in the Cost Optimizer page, thus enhancing the ability to manage resources based on application and business criticality. Using this feature, bulk recommendations can be skipped at a time for the defined timeframe.

The Policy Exclusion feature introduces a strategically governed mechanism for filtering out non-actionable or contextually irrelevant recommendations across operational domains. This capability empowers both tenant and account-level administrators with granular control over the recommendation engine’s output, aligning insights more closely with organizational priorities and operational nuances.
Key Capabilities:
Rule-Based Exclusion FrameworkUsers are empowered to define customizable exclusion rules that operate on a scheduled or ad-hoc basis. These rules act as dynamic filters, enabling intelligent suppression of recommendations for resources that are either out of scope or deemed non-impactful.
Multidimensional ApplicabilityThe feature spans across core pillars—Operations, Security, Cost, Access, and Resource classifications—ensuring comprehensive coverage. Cost-based exclusions focus specifically on suppressing cost savings recommendations, with current limitations on "schedule recommendation" exclusions.
Administrative Scope and Governance
Account-Level Rules: Configurable by account administrators, enabling localized control.
Tenant-Level Rules: Governed by tenant administrators, enabling organization-wide policy enforcement.
All applicable rules, whether tenant or account-based, are applied at the time of recommendation generation to ensure contextual relevance.
Filter-Driven Rule DefinitionEach rule encapsulates a set of filters such as cloud account, resource ID, tags, region and so on. This precision targeting enhances operational flexibility and optimizes the recommendation filtering process.
Temporal EffectivenessRules are defined with explicit effective periods—ranging from continuous application ("Always") to bounded intervals (e.g., Start-End Date) and pre-set durations (e.g., 7 days)—enabling time-aware policy enforcement.
Comprehensive Rule ManagementAdministrators can perform a full lifecycle of actions on each rule:
View & Edit – Access and modify rule configurations
Activate/Inactivate – Manage rule state transitions
Delete – Remove obsolete or redundant rules
View Log – Audit and trace rule activity for governance
Apply All Rule – Retroactively enforce rules against existing recommendations, eliminating the need for policy reassessment runs
