Cloud Spend Tagging and Cost Ownership Starter Kit

If cloud spend is untagged, it is unmanaged.

This starter kit installs a beginner-safe cost ownership system so Finance and Engineering can answer basic questions without chaos:

• who owns this spend
• what environment it belongs to
• what it supports
• what we should shut down or optimize first

This is not a perfect tagging program. It is the minimum viable system that actually sticks.

What you will produce

1. Minimum tag standard (required tags and allowed values)

2. Ownership rules (who owns shared and unknown spend)

3. Enforcement rules (what happens when tags are missing)

4. Exception process (how to request a tag exception)

5. Weekly governance cadence (15 minutes)

---

Beginner-safe definitions

Tag: a label attached to cloud resources to identify ownership and purpose.

Owner team: the team accountable for the spend and the decision to keep, downsize, or delete.

Environment: where the resource runs (prod, staging, dev).

Unowned spend: spend that cannot be attributed to a team due to missing tags or broken mapping.

Shared services: platform services used by multiple teams (logging, networking, data platforms).

---

Minimum viable tag standard

Start with 3 required tags. Only add more after you can enforce these.

Required tags

• owner_team
• environment
• cost_center

Optional tags

• service_name
• application
• project

---

Step-by-step implementation

Step 1: Choose the minimum required tags

Pick tags that map directly to decisions:

• who owns it
• where it runs
• how Finance books it

Beginner-safe defaults:

• owner_team (human accountability)
• environment (prod costs are treated differently than dev costs)
• cost_center (finance mapping)

---

Step 2: Define allowed values

If allowed values are unlimited, tags become inconsistent and useless.

Beginner-safe approach:

• environment allowed values: prod, staging, dev
• owner_team allowed values: your actual team list
• cost_center allowed values: your finance cost center codes

---

Step 3: Define ownership rules

You need rules for three cases:

Case A: Normal resources

• Each resource must map to exactly one owner_team.

Case B: Shared services

• Shared services must have a named platform owner team.
• Shared service costs can be allocated later if needed. First priority is ownership.

Case C: Unknown spend

• Unknown spend is reviewed weekly.
• Unknown spend must be assigned an owner within 7 days.
• If unowned after 14 days, it becomes a shutdown candidate.

---

Step 4: Define enforcement

Pick the enforcement level you can actually support.

Beginner-safe enforcement ladder:

1. Report only (week 1 to 2): build visibility and fix obvious gaps.
2. Escalate (week 3+): require owners to remediate untagged resources.
3. Block (later): prevent creation of new resources without required tags where feasible.

---

Step 5: Install the weekly governance cadence

Weekly (15 minutes) agenda:

• untagged spend
• top cost movers by owner_team
• new services created outside standards
• owners and deadlines

The goal is to make cost ownership boring and repeatable.

Subject: Action required: unowned cloud spend

We identified unowned or untagged cloud spend.

Requirement:
- Assign owner_team, environment, and cost_center tags within 7 days.

If the resource remains unowned after 14 days, it will be scheduled for shutdown review.

Common failure modes

• too many required tags at the start
• no allowed values, leading to inconsistent tagging
• no enforcement, so tags decay
• shared services treated as “no owner”
• governance happens monthly instead of weekly

Keep it simple, then improve.
