What a Cloud Cost Optimization Tool actually does
Analyzes multi-cloud usage telemetry to generate plain-English right-sizing recommendations, commitment-purchase scenarios, and CFO-readable executive FinOps reports — replacing 20+ hours of manual analysis per client per month.
A white-label AI cloud cost optimization tool ingests cost and usage data from AWS Cost Explorer, Azure Cost Management, and GCP Billing APIs, then applies AI to two distinct jobs: anomaly detection (statistical) and recommendation generation (LLM). The anomaly layer uses Isolation Forest or simple z-score on daily spend time series to flag unusual spikes — this requires no LLM and runs cheaply in a Python worker. The recommendation layer is where Claude Sonnet 4.6 ($3/$15 per M, 1M context) earns its cost: given a structured cost report showing 30 EC2 instances by CPU/memory utilization over 90 days, Sonnet produces a right-sizing recommendation table with projected monthly savings, a commitment-purchase scenario analysis (Reserved Instances vs. Savings Plans vs. Compute Savings Plans), and a 500-word CFO-readable narrative explaining the findings without AWS jargon.
The market in 2026 is dominated by tools that produce excellent data but poor communication — CloudHealth, Vantage, and Cloudability all output dashboards that FinOps-literate engineers understand but CFOs cannot action. The AI narrative layer is genuinely additive: a consultant who delivers a 'Your AWS bill will drop $8,400/mo if you switch these 12 instances from on-demand to 3-year Reserved — here's the amortized payback analysis' memo commands a premium retainer over one who hands over a Vantage dashboard screenshot. AWS/Azure/GCP read-only IAM credentials into customer accounts is the trust-killer — this access pattern triggers SOC 2 Type II scrutiny at every enterprise RFP.

SaaS alternatives on the market
Real products you can sign up for today — with current 2026 pricing, honest pros and cons.
Vantage
FinOps consultants with 3–8 clients who want professional tooling quickly and can live with Vantage branding in the client-facing view.
Free tier (limited accounts, delayed data)
$0–$2,000+/mo + 1.5% of savings
Custom (partner discount available)
Pros
- +Most modern UX in the FinOps SaaS category — clients find the dashboard intuitive without training.
- +Partner program provides discounts for MSPs and FinOps consultants reselling to clients.
- +Native integrations with AWS, Azure, GCP, Datadog, Kubernetes, and Snowflake costs in one view.
- +Active development — unit cost features and savings plan analyzer shipped in 2026.
Cons
- −No true white-label — 'Powered by Vantage' appears in client-facing dashboards and is in the URL.
- −1.5% cut of realized savings creates perverse incentives at scale: on $1M/mo in savings that's $15,000/mo you pay Vantage.
- −AI narrative generation (plain-English explanations) is not a Vantage feature — you still need to write the CFO summary manually.
- −Free tier data is 24-hour delayed — not usable for anomaly detection on fast-moving spend.
OpenCost
MSPs whose clients run primarily Kubernetes workloads and who have DevOps engineering capacity to maintain self-hosted infrastructure.
Open source / free (self-hosted)
$0 (self-host) + Kubernetes cluster cost
Kubecost Enterprise ($0 for open source, paid for managed)
Pros
- +Truly open source (Apache 2.0) — brand it as your own, no vendor attribution required.
- +Best-in-class Kubernetes cost attribution — essential for clients running containerized workloads.
- +CNCF project with broad ecosystem adoption — not subject to single-vendor shutdown risk.
- +Self-hosted means client cloud credentials never leave your infrastructure.
Cons
- −Requires Kubernetes cluster to deploy — adds operational complexity and $50–$200/mo for the cluster itself.
- −No managed SaaS version — all updates, security patches, and ops burden fall on the agency.
- −AWS/Azure out-of-cluster cost (EC2 not in the cluster, RDS, S3) requires separate integration — OpenCost is Kubernetes-native first.
- −No AI narrative layer — the plain-English CFO report must be built on top.
CloudHealth by VMware/Tanzu
Large MSPs (30+ enterprise accounts) already in the VMware ecosystem who need governance and compliance tooling at scale.
Demo only
~$25,000+/yr (enterprise quote)
Custom (no white-label)
Pros
- +Most comprehensive multi-cloud governance in the category — AWS, Azure, GCP, and on-prem in one platform.
- +SOC 2 Type II compliant — reduces your audit scope if you can route client credentials through their infrastructure.
- +Strong policy engine for automated right-sizing recommendations and budget alerts.
- +Used by large MSPs and enterprise IT teams — brand recognition in procurement conversations.
Cons
- −No white-label — CloudHealth/VMware branding is permanent in client-facing views.
- −At $25K+/yr you need 10+ mid-market clients to justify the entry cost.
- −Broadcom's acquisition of VMware in 2024 created pricing uncertainty — several MSPs reported 40–60% renewal increases.
- −No AI-generated narrative — dashboard is data-dense, not CFO-readable.
Spot by NetApp
MSPs with AWS-heavy clients running stateless, containerized workloads where spot instance savings are the primary optimization lever.
Free to connect; pay on savings
% of savings model (no fixed fee)
Custom (no white-label)
Pros
- +Zero upfront cost — only pay when savings are realized, making it low-risk for agencies testing the category.
- +Spot instances automation (Elastigroup) is the best-in-class for stateless workloads.
- +Significant engineering depth on EC2 spot interruption handling — reduces client risk from spot terminations.
- +Strong Kubernetes (Ocean) and container cost optimization.
Cons
- −Percentage-of-savings model can cost more than a flat-fee alternative at high-savings volumes.
- −No white-label — Spot.io branding is visible to clients.
- −Spot instance optimization is not appropriate for all workloads (databases, stateful services) — requires careful workload classification.
- −Less useful for Azure and GCP clients where AWS-specific spot mechanics don't apply.
The AI stack
The FinOps AI stack operates in three tiers at very different cost-efficiency points: cheap high-volume classification (tag cleanup, anomaly flags), moderate-cost structured analysis (right-sizing, commitment scenarios), and premium narrative generation (executive summaries). Route each job to the appropriately-priced model — Sonnet 4.6 for everything is 20× overspend on the classification tier.
Cost data ingestion and anomaly detection
Pulls daily/hourly cost data from cloud provider APIs, stores in time-series format, and flags anomalies using statistical methods before AI summary
Python + Isolation Forest (self-hosted, Fly.io)
~$20–$50/mo Fly.io computeAll anomaly detection — never use a frontier LLM for statistical anomaly detection when a simple algorithm is faster and cheaper
AWS Cost Anomaly Detection (native)
Free for AWS; no equivalent for Azure/GCPInternal monitoring only — not suitable as a client-facing branded service
Our pick: Python Isolation Forest on Fly.io for the anomaly detection pipeline — it's the only option that is multi-cloud, brand-neutral, and produces structured output for the downstream LLM narrative step.
Right-sizing recommendation generation
Takes structured resource utilization data and produces actionable right-sizing recommendations with projected savings per resource
Claude Sonnet 4.6
$3/$15 per M tokensAll client-facing right-sizing reports where quality and table formatting compliance matter
Mistral Large 3
$0.50/$1.50 per M tokensEU-based clients where GDPR data residency requires EU-hosted inference, and cost reports are under 262K tokens
GPT-5.4
$2.50/$15 per M tokensAlternative to Sonnet 4.6 when clients or contracts specify OpenAI models
Our pick: Claude Sonnet 4.6 as the primary recommendation engine. Route EU clients through Mistral Large 3 on EU-hosted inference. At $0.014/report-section (3K in + 400 out), a 100-resource account costs $1.40/month in LLM costs for right-sizing — well within any consulting retainer margin.
Commitment-purchase scenario modeling
Models Reserved Instance, Savings Plans, and Committed Use Discount scenarios with break-even analysis and cash-flow projections
Claude Sonnet 4.6
$3/$15 per M tokensCommitment scenario narrative and recommendation — always validate the numbers against the cloud provider's own calculator before delivery
Python financial model + Sonnet narrative
$0 (Python compute) + $3/$15 per M (Sonnet narrative only)Production FinOps platforms where commitment math accuracy is client-contractual — the Python model is the source of truth, Sonnet explains it
Our pick: Python financial model for the commitment arithmetic (RI payback period, break-even month, 3-year NPV) + Sonnet 4.6 for the CFO-readable narrative that explains the Python model's output. Never let the LLM do the math solo on financial commitments — validate against AWS Savings Plans calculator.
Tag-policy enforcement and cost allocation
Classifies untagged or mis-tagged cloud resources and suggests tag corrections to enable accurate cost allocation by team/project/environment
DeepSeek V4 Flash
$0.14/$0.28 per M tokensHigh-volume tag classification (1,000+ untagged resources/month) where cost is the primary constraint
GPT-5.4 nano
$0.20/$1.25 per M tokensAccounts where tag classification volume is moderate (<500 resources/month) and latency matters
Our pick: DeepSeek V4 Flash for all tag classification — at $0.00015/resource it's effectively free even at enterprise scale. Set a confidence threshold of 80% and route below-threshold resources to a human-review queue in the client portal.
Reference architecture
The hardest engineering challenge is not the AI layer — it's the secure per-tenant IAM credential management for cross-account AWS/Azure/GCP access. Every client's cloud credentials must be stored in an encrypted vault (Supabase Vault or AWS Secrets Manager), isolated by tenant_id, and accessed only by a read-only IAM role. The AI pipeline itself is a straightforward ETL + LLM pattern.
Client onboarding: agency admin creates tenant and configures cloud credentials (AWS cross-account role ARN, Azure service principal, GCP service account)
Next.js admin onboarding wizard + Supabase Vault for credential encryptionCredentials stored in Supabase Vault (envelope encryption with tenant-specific KMS key). Never stored in plaintext. AWS onboarding generates a CloudFormation template for the client to deploy the least-privilege read-only IAM role.
Nightly: cost ingestion job pulls 90 days of usage data from AWS Cost Explorer, Azure Cost Management, and GCP Billing APIs
Trigger.dev scheduled job (nightly 2am UTC) → Python worker on Fly.ioPython worker assumes the client's IAM role via STS AssumeRole (AWS) or equivalent. Fetches resource-level cost + utilization data. Stores normalized in Supabase cost_records table partitioned by tenant_id + date.
Anomaly detection runs on new daily cost data using Isolation Forest
Python Fly.io worker (scikit-learn Isolation Forest)Trains per-client per-service baseline on 60-day rolling window. Flags anomalies above 2σ. Stores in cost_anomalies table. Triggers Sonnet 4.6 to generate a plain-English anomaly explanation if any flag fires.
Weekly: right-sizing report generated for each tenant
Trigger.dev weekly job → Supabase Edge Function → Sonnet 4.6Fetches 90-day EC2/RDS/GKE utilization by service. Builds structured JSON of {service_id, type, avg_cpu, avg_memory, current_cost, recommended_type, projected_savings}. Passes to Sonnet 4.6 with right-sizing prompt. Stores JSON output in weekly_reports table.
Tag compliance audit runs monthly — classifies untagged resources via DeepSeek V4 Flash
Trigger.dev monthly job → DeepSeek V4 Flash Edge FunctionFetches all resources with missing or invalid tags per tenant. DeepSeek V4 Flash classifies each by environment (dev/staging/prod), team, and cost-center based on resource name + metadata. Results stored in tag_suggestions table with confidence scores.
Monthly executive summary generated by Sonnet 4.6 from all report data
Trigger.dev monthly job → Sonnet 4.6 Edge Function → React PDF rendererAggregates the week's right-sizing recommendations, anomaly history, tag compliance score, and commitment purchase opportunities. Sonnet 4.6 writes a 500-word CFO-readable narrative with three action items ranked by savings potential. React PDF renders a branded PDF report stored in Supabase Storage.
Client dashboard displays reports; PDF auto-emailed to client CFO and the FinOps consultant
Next.js client portal + Resend for PDF email deliveryEach tenant has an isolated portal view (RLS enforced). Right-sizing report is interactive (filter by region, service type, projected savings). PDF email sent via Resend on the 1st of each month from the agency's custom domain.
Estimated cost per request
~$0.014 per right-sizing report section (Sonnet 4.6, 3K in + 400 out). A 100-service account = $1.40/month for right-sizing + $0.022 for the executive summary + $0.00015 per untagged resource classified (DeepSeek). Total AI cost for a mid-size client: ~$2–$4/month. Infrastructure (Fly.io + Supabase + Vercel) adds $15–$25/client/month at 30-client scale.

≈ $1,469 per year
Calculator notes
- Cloud provider API costs (AWS Cost Explorer API: $0.01/1,000 requests) are not included — budget $5–$20/client/month for API calls at typical query frequency.
- Commitment-purchase scenario modeling uses Sonnet 4.6 on the same per-resource-section cost; model as an additional $0.014 × (services being analyzed for commitments).
- Anomaly detection uses Python Isolation Forest (no LLM cost) — anomaly explanation narrative via Sonnet 4.6 adds ~$0.005 per fired alert.
- SOC 2 Type II audit ($40,000–$60,000 one-time + $15,000–$25,000/yr ongoing for Vanta) is not modeled — it's a separate line item for production enterprise deployments.
Build it yourself with vibe-coding tools

Starter prompt
Build a cloud cost optimization admin tool using Next.js App Router and Supabase. This is an INTERNAL POC for one account only — not multi-tenant yet. Supabase schema: - cost_records (id, service_name, region, resource_id, resource_type, date, daily_cost_usd, avg_cpu_pct, avg_memory_pct, current_instance_type) - right_sizing_reports (id, generated_at, report_json, executive_summary_text, total_projected_savings_usd) - cost_anomalies (id, service_name, date, cost_usd, expected_cost_usd, deviation_pct, explanation_text) - tag_suggestions (id, resource_id, resource_name, suggested_environment, suggested_team, confidence_score) Pages to build: 1. /dashboard — monthly spend chart by service + top-5 anomalies with Sonnet explanation text 2. /right-sizing — table of resources with current vs. recommended type, projected savings, filter by region/service 3. /executive-report — rendered view of the latest Sonnet 4.6 executive summary + download PDF button 4. /tags — table of untagged resources with DeepSeek V4 Flash suggestions + approve/reject buttons Use Tailwind CSS + shadcn/ui + Recharts for the spend charts. Server Components everywhere except the chart and PDF download.

Follow-up prompts (run in order)
- 1
Add a Supabase Edge Function that calls the AWS Cost Explorer API (using AWS SDK with credentials from environment variables for POC), fetches the last 90 days of resource-level cost and utilization data, and inserts normalized records into cost_records table. Schedule this via Trigger.dev to run nightly at 2am UTC.
- 2
Add a Supabase Edge Function that takes all cost_records from the last 90 days, groups by service and resource, builds a structured JSON input showing {resource_id, current_type, avg_cpu_90d, avg_memory_90d, current_monthly_cost}, and calls Claude Sonnet 4.6 with a right-sizing prompt. The prompt asks Sonnet to return a JSON array of {resource_id, recommended_type, projected_monthly_savings, reasoning}. Store in right_sizing_reports.
- 3
Add a Supabase Edge Function that generates the monthly executive summary. Aggregate: total current monthly spend, total projected savings from right-sizing recommendations, top-3 anomalies this month, tag compliance score (pct of resources tagged). Pass this structured data to Sonnet 4.6 with instructions to write a 400-word CFO-readable narrative with three prioritized action items. Store in right_sizing_reports.executive_summary_text.
- 4
Add a Supabase Edge Function for tag classification. For each resource where tags are missing, call DeepSeek V4 Flash with the resource name, type, and region, asking it to classify: environment (dev/staging/prod/unknown), team (infer from name), confidence (0-100). Store in tag_suggestions with confidence score. Add an approve button that writes the approved tag back to the cost_records table.
- 5
Add a React PDF export component on the /executive-report page using @react-pdf/renderer. The PDF includes the agency logo (from Supabase Storage), the Sonnet-generated executive summary text, and a summary table of the top-10 right-sizing recommendations with projected savings. Add a download button and a Resend-powered 'Email to client' button.
Expected output
A single-tenant internal dashboard that pulls real cost data from your own AWS account, generates AI right-sizing recommendations and an executive summary via Claude Sonnet 4.6, classifies untagged resources via DeepSeek V4 Flash, and exports a branded PDF report — proof of concept for the value proposition before multi-tenant production architecture.
Known gotchas
- !AWS Cost Explorer API returns aggregated data, not per-instance utilization — you need CloudWatch metrics for CPU/memory. The POC can use Cost Explorer alone, but production right-sizing needs CloudWatch, which adds per-request costs and additional IAM permissions.
- !Lovable will generate AWS SDK calls from the browser, exposing your IAM credentials. Move all AWS API calls to Supabase Edge Functions that use server-side environment variables — never expose IAM credentials to the client.
- !Claude Sonnet 4.6's 1M context handles large cost reports, but at $3/$15 per M tokens, a 200K-token monthly report (100+ resources × detailed history) costs $0.60/report — budget this explicitly for production scale.
- !OpenCost requires Kubernetes — you cannot deploy it from Lovable. The cost_records ingestion must come from either OpenCost's API (if you have a cluster) or AWS Cost Explorer API (if AWS-only). The POC can use Cost Explorer; production needs both.
- !Never store client AWS credentials in environment variables for a multi-tenant system — this is the most common security failure in FinOps tools. Production must use Supabase Vault with per-tenant KMS keys and AWS STS AssumeRole.
Compliance & risk reality check
A FinOps platform holding read-only cloud credentials to 30 enterprise client accounts is one of the highest-trust positions in the MSP stack — a credential leak is a brand-ending event. Compliance requirements reflect this trust level.
SOC 2 Type II (critical for enterprise client credentials)
Any platform that holds AWS/Azure/GCP credentials to enterprise customer accounts will be asked for SOC 2 Type II in every enterprise RFP. The audit covers: data at rest encryption (credentials in Supabase Vault), data in transit encryption (TLS 1.3), per-tenant data isolation (RLS), access logging, employee access controls, and incident response procedures. Standing up SOC 2 Type II from scratch takes $40,000 and 6–9 months.
Mitigation: Use Vanta ($4,000–$25,000/yr) for automated evidence collection. Supabase Pro infrastructure is already SOC 2 Type II compliant — your application layer needs the additional controls. Store all credentials in Supabase Vault with envelope encryption. Implement comprehensive access logging via Supabase audit logs. Run the SOC 2 readiness assessment 6 months before pitching your first enterprise client.
Per-tenant cloud credential isolation (critical)
The most dangerous failure mode for a multi-tenant FinOps platform is cross-tenant credential access — where an error in RLS policy causes Client A's AWS role to be accessible from Client B's session. This is not a theoretical risk: it has happened to FinOps SaaS platforms, and the AWS IAM access logs will show the breach within minutes. Recovery requires notifying every affected client, triggering their incident response, and likely losing the accounts.
Mitigation: Store credentials in Supabase Vault with tenant_id-keyed encryption. Never return credentials to the frontend — all cloud API calls run in server-side Edge Functions or Fly.io workers. Add automated tests that assert: given a valid session for Tenant A, no API call can return data tagged with Tenant B's tenant_id. Run these tests on every deployment.
AWS/Azure/GCP least-privilege IAM design
The read-only role deployed in client accounts must be scoped to the minimum permissions needed: Cost Explorer read, CloudWatch GetMetricStatistics, EC2 DescribeInstances, RDS DescribeInstances, and tagging read APIs. Any broader permission scope will fail enterprise security reviews. The AWS CloudFormation template you provide clients for role setup must explicitly deny all write permissions.
Mitigation: Provide clients a pre-built CloudFormation/Terraform template that creates an IAM role with explicit deny statements for all write/delete actions. Include the template in client onboarding documentation. Have a security engineer review the IAM policy before the first enterprise client deployment.
ISO 27001 for international enterprise clients
UK and EU enterprise clients will add ISO 27001 to SOC 2 Type II requirements. ISO 27001 covers the broader information security management system (ISMS), not just technical controls. Scope includes: asset inventory, vendor risk management, business continuity, and security awareness training for all employees with access to client credentials.
Mitigation: ISO 27001 certification alongside SOC 2 adds $30,000 and 6 months. For initial launch, use a SOC 2 Type II report to satisfy international clients where possible — ISO 27001 is typically a Year 2 objective. Drata ($7,500+/yr) supports both SOC 2 and ISO 27001 evidence collection.
Per-tenant LLM spend caps (critical for cost-spiral prevention)
A Trigger.dev misconfiguration that causes the right-sizing job to run in an infinite loop across 30 tenants × 1,000 resources at Sonnet 4.6 pricing can generate thousands of dollars in API costs in hours. This is not hypothetical — see the ai-compliance section on agentic spend spirals.
Mitigation: Set hard per-client monthly LLM spend caps in the Trigger.dev job configuration. Configure Anthropic usage alerts at $50, $100, and $200 per month thresholds. Add a circuit-breaker in the Edge Function that checks the current month's LLM spend for the tenant before making an API call and returns an error if the cap is exceeded.
Build vs buy: the real math

Custom build time
$45,000–$95,000
One-time investment
8–12 months
Breakeven vs buying
At $45,000–$95,000 build cost, the breakeven math depends on retainer uplift. If the AI recommendation reports enable a $1,500/mo premium on 10 FinOps retainers (from $2,000 standard to $3,500 AI-enhanced), you generate $180,000/yr in incremental revenue — recovering the build cost in 3–6 months at the upper end. The real comparison is against the Vantage partner program: at $0–$2,000/mo + 1.5% of savings, a consultant with 10 clients saving a combined $100,000/mo pays Vantage $1,500/mo in perpetuity ($18,000/yr). At 3 years that's $54,000 — comparable to the custom build cost, but you own the IP and keep improving it. As Sonnet 4.6 prices continue falling (expected 30–40% reduction by mid-2027), AI COGS margin widens automatically, making the custom build increasingly more profitable over time.

Frequently asked questions
How much does it cost to build a white-label AI cloud cost optimization tool?
The realistic range is $45,000–$95,000 with RapidDev — above the standard band specifically because of the SOC 2-grade IAM credential management, per-tenant data isolation, and multi-cloud API engineering required. If you exclude SOC 2 setup (an additional $40,000 + 6 months), the pure software build is $40,000–$70,000. The Lovable internal POC costs $25 Lovable Pro + ~$40 in Sonnet API credits and takes a weekend — but it's a one-account demo, not a production platform.
How long does it take to ship a production-ready FinOps platform?
The AI recommendation layer on top of OpenCost: 12–18 weeks. SOC 2 Type II audit: an additional 6–9 months run in parallel. If you start the SOC 2 process on day 1 and the build on day 1, a SOC-2-certified platform can be enterprise-ready in 9–12 months total. Without SOC 2, the platform will be blocked at enterprise security review regardless of technical quality.
Can RapidDev build this for my MSP?
Yes — we've shipped cloud infrastructure tooling and multi-tenant SaaS platforms. This build specifically requires SOC 2-grade IAM engineering, which is part of our scope. Our standard quote for the AI FinOps layer is $45,000–$95,000 and includes the OpenCost integration, Supabase multi-tenant backend, Sonnet 4.6 recommendation pipeline, and branded client portal. Book a free 30-minute consultation at rapidevelopers.com to scope your specific account mix and cloud providers.
Do I need SOC 2 Type II before I can sell this to enterprise clients?
Yes, for any enterprise client managing over $100,000/month in cloud spend. They will ask for SOC 2 Type II before handing over an IAM role with read access to their cloud accounts. The audit takes 6–9 months and costs $40,000–$60,000 one-time plus $15,000–$25,000/yr ongoing. Vanta ($4,000–$25,000/yr) automates most of the evidence collection. Plan SOC 2 as a parallel workstream from day 1, not as something you do after launch.
What's the real risk of using a Lovable-built app with client cloud credentials?
The risk is catastrophic and non-recoverable. A Lovable-scaffolded app with AWS credentials in environment variables, shared across 30 tenants with unchecked Supabase RLS policies, is one misconfiguration away from exposing Client A's AWS role to Client B's browser session. When that happens, you notify all 30 clients of a credential breach, they rotate credentials, you lose the accounts, and AWS Security Hub generates a finding in every affected account. Never use a Lovable POC for multi-tenant client credential storage.
What's the difference between Vantage and a custom-built platform?
Vantage delivers excellent cost dashboards under the Vantage brand, takes 1.5% of realized savings, and gives you no AI narrative generation. A custom RapidDev build delivers the same recommendations under your brand, lets you keep 100% of the savings-driven upsell value, and adds Sonnet 4.6-generated CFO executive summaries that Vantage doesn't offer. The break-even point between Vantage's partner model and a custom build is typically 10–15 accounts at $100,000+/month each in total cloud spend.
Can the AI really identify right-sizing opportunities accurately?
The AI is accurate for the recommendation narrative — the hard part is accurate utilization data. Claude Sonnet 4.6 is excellent at turning 'this EC2 instance ran at 8% CPU for 90 days' into a structured recommendation table. The bottleneck is CloudWatch telemetry quality: if clients have resource-level monitoring disabled, the utilization data is missing and Sonnet can only recommend based on cost, not usage. Part of the FinOps platform's value is ensuring every client has CloudWatch detailed monitoring enabled before the right-sizing engine has meaningful data to analyze.
