What Is an AWS Well-Architected Review — and Why Your Business Needs One

What is an AWS Well-Architected Review — and why does your business need one?

If you run workloads on Amazon Web Services, you have probably heard the term "Well-Architected Review" mentioned at some point — possibly by your AWS account manager, possibly on an invoice, possibly in a conversation you quickly moved on from. It sounds like something important. It also sounds like something that might take a long time and cost a lot.

In this article, I want to demystify it — explain exactly what a Well-Architected Review (WAFR) involves, what it produces, and whether your business actually needs one.

What is a Well-Architected Review?

An AWS Well-Architected Review is a structured assessment of your cloud environment against Amazon's six Well-Architected Framework pillars: Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimisation, and Sustainability.

It is not a penetration test. It is not an audit in the compliance sense. It is closer to a structural survey — a systematic check of how your AWS environment is built, with the goal of identifying risks and improvement opportunities before they cause incidents or runaway costs.

The process is conducted by an AWS Well-Architected Partner (like us) using a formal set of questions developed and maintained by AWS. At the end, you receive a report that documents findings, assigns risk ratings (High, Medium, Low), and provides prioritised improvement recommendations.

The six pillars — briefly explained

Operational Excellence: How well are your operations designed? Are your processes documented, monitored, and able to respond effectively to events?

Security: Is access managed correctly? Are your data stores encrypted? Are your security groups, IAM policies, and network configurations following least-privilege principles?

Reliability: Can your system recover from failures? Do you have backup and recovery processes in place? Are your workloads designed to handle disruption?

Performance Efficiency: Are you using the right AWS services for the job? Are your compute resources correctly sized, or are you running oversized instances that cost more than they should?

Cost Optimisation: Are you paying for what you actually use? Are there Savings Plans, Reserved Instances, or Spot Instance opportunities you have not yet taken advantage of?

Sustainability: Are your workloads designed to minimise energy consumption and environmental impact? This pillar was added in 2021 and is increasingly relevant for organisations with ESG commitments.

What does the process actually look like?

A Well-Architected Review follows a defined process regardless of which AWS Partner delivers it.

Step 1 — Scoping. We agree which workloads to review. For smaller businesses, this is often a single production environment. For larger organisations, it might be a specific application or a representative subset of workloads.

Step 2 — Discovery session. A structured interview — typically 90 minutes to 2 hours — where we work through the AWS question set with your technical team (or with us if you do not have one). We are looking at architecture decisions, security configuration, operational processes, and cost management practices.

Step 3 — Analysis and report. We document findings, assign risk levels, and write prioritised recommendations. High-risk items are flagged for immediate attention. Medium and Low items form a longer-term improvement backlog.

Step 4 — Review presentation. We walk you through the findings, explain the rationale behind each recommendation, and agree on a remediation plan.

The entire process typically takes one to two weeks from kickoff to report delivery.

What does it cost?

A Well-Architected Review with Smile IT Solutions is free for qualifying customers. AWS funds a proportion of the cost through the Well-Architected Partner Programme — the credits are applied to your AWS account as part of the process.

To qualify, your workloads need to have an active AWS Sales Opportunity linked in AWS Partner Central. We create this on your behalf as part of the WAFR process — it is standard procedure, and it does not obligate you to anything.

What do you actually get at the end?

You receive a written report with every finding documented, risk-rated, and linked to a specific recommendation. The report is yours to keep — it is not a sales document, it is a technical deliverable you can act on independently or with our help.

Typical findings include: over-permissive IAM roles, unencrypted Amazon S3 buckets, missing backup policies, orphaned resources increasing your bill, and architecture patterns that create single points of failure.

Who should get a Well-Architected Review?

Any business running production workloads on AWS that has not had a formal review in the past twelve months should consider one. In our experience, the businesses that benefit most are those that:

• Built their AWS environment quickly — often during rapid growth — without time for architectural rigour
• Have inherited an AWS environment from a previous team or agency
• Are experiencing unexplained cost increases without a clear cause
• Have had a security incident or near-miss and want to understand their risk exposure
• Are preparing for a funding round or acquisition and need to evidence technical due diligence

How is this different from a Cloud Health Check?

Our Free Cloud Health Check is a 30-minute discovery call designed to give you a rapid, practical view of your biggest opportunities and risks. It is a conversation, not a formal assessment.

A Well-Architected Review is a full structured assessment, producing a formal report with specific findings and recommendations. The Health Check often leads into a WAFR for businesses where we identify significant risk or cost exposure.
