Most CLF-C02 study time goes to services: what S3 does, how EC2 is billed, which database is serverless. But a reliable slice of the exam asks a different kind of question: who do you call? A company with no cloud skills wants to migrate. A security team needs third-party firewall software billed through AWS. A startup wants someone else to run patching and backups. An engineer has a question at 2 a.m. and no paid Support plan. Each scenario maps to a specific AWS resource or engagement model, and the exam expects you to tell them apart.
This guide covers that map for the AWS Certified Cloud Practitioner: AWS Marketplace, the AWS Partner Network (APN), AWS Professional Services, AWS Managed Services (AMS), AWS Solutions Architects, AWS re:Post, AWS Prescriptive Guidance, the Solutions Library and the rest of the self-service technical resources. Support plans, Trusted Advisor and the Health Dashboard are covered in our dedicated Support plans and Trusted Advisor guide, so here we focus on everything around a Support case — and on the 2026 change that retired AWS IQ.
Where This Sits in the Exam
The CLF-C02 exam guide splits the content into four domains. The resources in this article live mainly in Domain 4, Billing, Pricing and Support (12%), under the task statement that asks you to identify AWS technical resources and AWS Support options. They also surface in Domain 1, Cloud Concepts (24%), where migration and cloud-adoption scenarios reference AWS Professional Services, partners and the Cloud Adoption Framework. Our domains breakdown shows how the weights fit together.
The exam does not expect you to have used any of these. It expects you to recognise, from a one-sentence scenario, which one is being described. So the goal of this article is a clean, differentiated definition of each, plus the trigger words that point to it.
The Resource Map at a Glance
| You need… | The answer is… | Paid? |
|---|---|---|
| Third-party software or data, billed on your AWS invoice | AWS Marketplace | Per product (many free trials) |
| A consulting firm or software vendor validated by AWS | AWS Partner Network (APN) partner | Partner’s own pricing |
| AWS’s own consultants embedded in a large migration or adoption programme | AWS Professional Services | Yes |
| AWS to operate your infrastructure day to day (patching, backup, monitoring) | AWS Managed Services (AMS) | Yes |
| Architecture advice from your AWS account team | AWS Solutions Architects | Included with the account relationship |
| Community answers and AWS-curated troubleshooting articles | AWS re:Post (includes the Knowledge Center) | Free |
| A documented strategy, guide or pattern for a specific problem | AWS Prescriptive Guidance | Free |

| Self-paced learning and exam prep from AWS | AWS Skill Builder / Training and Certification | Free and paid tiers |
| A human engineer on a case with a response-time SLA | AWS Support plan | Developer / Business / Enterprise On-Ramp / Enterprise |
Keep this table in mind; the rest of the article explains each row in enough depth to handle the distractors.
AWS Marketplace
AWS Marketplace is a curated digital catalog where you find, buy, deploy and manage third-party software, data and services that run on or with AWS. Think of it as the app store for your AWS account, with one important difference: AWS handles the billing. Charges for Marketplace products appear on your AWS bill, AWS collects payment, and AWS pays the seller.
What you can buy
| Product type | Delivered as | Example use |
|---|---|---|
| Server software | Amazon Machine Image (AMI), optionally with a CloudFormation template that deploys a whole stack | Firewalls, databases, monitoring agents on EC2 |
| Container software | Images for Amazon ECS / EKS | Packaged microservices, ingress controllers |
| SaaS | Subscription to a vendor-hosted service, integrated with your AWS account | Security, observability, data tools |
| Machine learning | Models and algorithms for Amazon SageMaker | Pre-trained vision or NLP models |
| Data products | Datasets via AWS Data Exchange | Financial, weather, demographic data |
| Professional services | Fixed-scope consulting, implementation or training engagements from partners | Migration assessments, managed onboarding |
| AWS WAF rules | Managed rule groups | Pre-built web ACL protections |
How pricing and procurement work
- Pricing models: free trial, hourly, monthly, annual, multi-year and Bring Your Own License (BYOL) for software you already own.
- Standard contract or private offer: buy at the listed price under the vendor’s end-user license agreement, or accept a private offer — custom pricing and terms a seller extends to one buyer, typically for large or negotiated deals.
- Private Marketplace: an administrator-curated catalog for an AWS Organization. Employees see and can subscribe only to products the organisation has approved. The exam trigger is “limit which third-party products teams can purchase”.
- Vendor Insights: a security and compliance profile (certifications, evidence, risk data) for a listed product, so a buyer can assess a vendor without a separate questionnaire.
- Every software listing goes through an AWS curation process before it is published.
Anyone with an AWS account can buy. Sellers are independent software vendors (ISVs), value-added resellers or individuals who register through the seller programme.
Exam framing: the scenario words are third-party, pre-configured, consolidated billing, procure and deploy in a few clicks. If a question asks where to get a commercial product that runs on EC2 and is billed through AWS, the answer is AWS Marketplace, not Support, not a partner.
The AWS Partner Network (APN)
The AWS Partner Network is AWS’s global programme for companies that build on or deliver AWS: consultancies, software vendors, resellers, training providers and hardware makers. For the exam, the two historical partner categories still frame most questions:
- Consulting partners (now the Services path) — professional services firms that help customers design, build, migrate and manage workloads.
- Technology partners (now the Software path) — ISVs whose products run on or integrate with AWS, many of them sold through AWS Marketplace.
Partner paths and tiers
APN organises partners into five paths:
| Path | Who | Entry requirement |
|---|---|---|
| Software | ISVs with a product on AWS | Foundational Technical Review of the product |
| Hardware | Device makers | Device qualification |
| Services | Consulting, MSPs, system integrators | Earn a tier |
| Training | Authorised training providers | Earn a training tier |
| Distribution | Resellers that distribute to other partners | Invite-only agreement |
Within the Services path, partners climb a tier ladder: Registered → Select → Advanced → Premier. Each step requires more AWS-certified staff, more documented customer launches and more verified customer satisfaction. Premier is the top tier for partners recognised as leaders in their market.
Partner programs you may see named
- AWS Competency Program — validates deep expertise in an industry (healthcare, financial services), a use case (migration, security, DevOps) or a workload.
- Service Delivery Program — validates that a partner can deliver a specific AWS service well (for example, an Amazon RDS or AWS Lambda service delivery designation).
- Service Ready Program — validates that a software product works with a specific AWS service.
- Managed Service Provider (MSP) Program — validates partners that operate customer environments.
- Well-Architected Partner Program — partners trained to run Well-Architected reviews, tying into the Well-Architected Framework you already know from Domain 1.
- AWS Partner Solutions Finder — the public directory customers use to search for partners by competency and location.
Exam framing: “no in-house AWS expertise”, “needs help migrating”, “wants a validated consulting firm” point to an APN partner. The distinction from Professional Services is who employs the people: an APN partner is an independent company; Professional Services is AWS itself.
AWS Professional Services
AWS Professional Services is AWS’s own global team of consultants. They are engaged — usually by larger enterprises — to work alongside the customer’s team and, frequently, an APN partner, on outcomes like a large-scale migration, a data-platform build, a security transformation or an operating-model redesign. They bring AWS methodologies, among them the AWS Cloud Adoption Framework (CAF), which organises cloud transformation into six perspectives: Business, People, Governance, Platform, Security and Operations. CAF and migration strategy are deeper topics in their own right; the SAP-C02 migration strategies guide goes further for readers continuing past the Practitioner level.
Professional Services also publishes much of the content that becomes AWS Prescriptive Guidance (below), which is how its playbooks reach customers who never buy an engagement.
Exam framing: “AWS experts”, “work with the customer’s own team on an enterprise migration”, “Cloud Adoption Framework”. Professional Services is a paid engagement for project work; it does not run your environment afterwards. That is Managed Services.
AWS Managed Services (AMS)
AWS Managed Services operates your AWS infrastructure on your behalf. Where Professional Services helps you build and move, AMS runs what you have: monitoring and incident management, patch management, backup and restore, change management, security and compliance controls, and cost-optimisation recommendations — delivered by AWS engineers under defined operational processes and SLAs.
AMS comes in two operational plans:
| Plan | Model | Typical customer |
|---|---|---|
| AMS Accelerate | AWS operates workloads in your existing accounts; you keep control of architecture and deployment, AMS adds operations (monitoring, patching, backup, security, incident response). | Teams that already run on AWS and want to offload operations without re-platforming |
| AMS Advanced | AWS provisions and operates a managed landing zone; changes go through AMS change management (requests for change). Stronger guard-rails, more prescriptive. | Regulated enterprises wanting a fully managed, compliant environment |
Note the overlap with the Shared Responsibility Model: AMS shifts some of the customer’s responsibilities (OS patching, backups, monitoring) onto AWS as a paid service, but it does not change the underlying model — AWS is still responsible for security of the cloud, and you still own your data and access decisions.
Exam framing: “ongoing operations”, “patching and backups”, “does not want to hire an operations team”, “24x7 monitoring by AWS”. If the scenario is about running infrastructure continuously, the answer is AMS, not Professional Services and not a Support plan (Support answers cases; it does not operate your environment).
AWS Solutions Architects and Your Account Team
Every AWS customer has an account team; its size depends on spend. The two roles the exam names:
- Account Manager — commercial relationship, pricing, programmes.
- Solutions Architect (SA) — technical guidance: architecture reviews, service selection, Well-Architected discussions. SAs are advisory; they do not build or operate systems for you.
A Technical Account Manager (TAM) is different: TAMs come with Enterprise On-Ramp (a pool of TAMs) and Enterprise Support (a designated TAM) and act as your ongoing operational advocate. The distinction between an SA (pre-sales / architecture) and a TAM (Support-plan operational advisor) is a popular distractor, and the TAM side is covered in the Support plans guide.
AWS re:Post (and the Knowledge Center)
AWS re:Post is AWS’s free, managed community Q&A service and the successor to the old AWS Forums. You can ask questions, answer others, and read AWS-authored and community-authored articles. Two things the exam expects you to know:
- It is free and available on every Support plan, including Basic. A team with no paid Support plan still has re:Post, documentation and whitepapers.
- The AWS Knowledge Center lives inside re:Post. The Knowledge Center is the library of AWS-written troubleshooting and how-to articles (“How do I resolve 403 errors from CloudFront?”). Older material treats the Knowledge Center as a separate site; today its articles are published on re:Post.
There is also re:Post Private, a private, organisation-specific version with curated content and AWS technical experts, available only to customers on Enterprise On-Ramp or Enterprise Support. It is a niche feature for the exam, and AWS has announced its end of support for June 30, 2027, so do not over-invest in it — the free public re:Post is what questions mean.
Exam framing: “free”, “community”, “no Support plan”, “crowd-sourced answers”, “Knowledge Center article”.
AWS Prescriptive Guidance, the Solutions Library and the Documentation Set
These are the self-service, free technical resources. They are easy to confuse because the names are similar, so anchor each to its shape:
| Resource | Shape | Trigger words |
|---|---|---|
| AWS Documentation | Reference manuals, user guides and API references for every service | ”how a service works”, “API reference” |
| AWS Whitepapers and guides | Long-form papers on architecture, security, cost and best practice | ”best practices document”, “Well-Architected paper” |
| AWS Prescriptive Guidance | Strategies, implementation guides and reusable patterns written by AWS experts and partners for specific scenarios (migrate an Oracle database, set up a landing zone) | “step-by-step guide for a specific migration or workload” |
| AWS Solutions Library | Vetted, deployable solutions and reference architectures, often with a CloudFormation template | ”ready-to-deploy reference architecture” |
| AWS Architecture Center | Reference architecture diagrams and best-practice collections | ”architecture diagrams” |
| AWS Well-Architected Tool | Console tool to review a workload against the six pillars | ”assess workload against best practices” |
| AWS Skill Builder / Training and Certification | Courses, labs and exam prep | ”train staff”, “certification” |
Our Skill Builder guide and free resources roundup cover the training side in more detail.
Exam framing: when a question says a team wants to “follow a proven, documented approach” for a specific project, the answer is Prescriptive Guidance. When it says they want to “deploy a reference architecture quickly”, it is the Solutions Library. When it says “understand a service’s features”, it is the Documentation.
AWS Activate
AWS Activate is the programme for startups: AWS credits, training, technical support and architecture guidance for early-stage companies, often reached through accelerators and venture firms. It is the only “resource” in this article aimed at a company stage rather than a technical need, which is exactly why it appears as a distractor. Trigger words: “startup”, “credits”, “early stage”.
The 2026 Change: AWS IQ Is Gone
Older CLF-C02 study material — and some question banks — mention AWS IQ, a service for hiring AWS-certified freelance experts for short engagements, with payment through your AWS bill. AWS announced in May 2025 that it was discontinuing IQ: new expert registrations ended May 20, 2025, and the service shut down on May 28, 2026. AWS directed customers to AWS Marketplace Professional Services and APN partners instead.
What that means for you:
- If a scenario describes “hire a certified freelance expert for a short task, paid through the AWS bill”, the current-world answer is Professional Services listings on AWS Marketplace, delivered by APN partners.
- If an old practice question lists AWS IQ as the correct answer, understand why it was correct (short engagement, individual experts, Marketplace-style billing) and map that to Marketplace Professional Services today.
- Do not confuse AWS Marketplace Professional Services (partner-delivered, listed and billed via Marketplace) with AWS Professional Services (AWS’s own consulting organisation). Same two words, different providers.
The official exam guide is periodically refreshed; be ready for either phrasing.
Scenario Drills
Work each of these before reading the answer. They mirror the exam’s one-line style.
1. A retailer with no cloud experience wants to migrate 200 servers to AWS within a year and needs a firm to design and execute the migration. → An APN Services partner (consulting partner). AWS Professional Services is also plausible for a large enterprise, but “a firm” plus “no experience” points to a partner.
2. A financial-services company wants AWS engineers to handle OS patching, backups and 24x7 monitoring for its production accounts after migration. → AWS Managed Services (AMS).
3. A security team needs a commercial next-generation firewall that runs on EC2 and wants the cost on its existing AWS invoice. → AWS Marketplace (AMI product, consolidated billing).
4. An administrator must ensure developers can subscribe only to a pre-approved list of third-party tools. → AWS Marketplace Private Marketplace.
5. A vendor offers the company a discount for a three-year commitment to its SaaS product on AWS. → A private offer on AWS Marketplace.
6. A developer on the Basic Support plan has a question about an unexpected S3 error and wants help without opening a technical case (which Basic does not include). → AWS re:Post (including Knowledge Center articles).
7. A migration team wants a step-by-step, AWS-written guide for moving a specific database engine to Amazon Aurora. → AWS Prescriptive Guidance.
8. A platform team wants a ready-made, deployable architecture for a centralised logging solution. → AWS Solutions Library.
9. An enterprise wants AWS’s own consultants to lead its cloud operating-model transformation using the Cloud Adoption Framework. → AWS Professional Services.
10. A two-person startup needs credits and guidance to build its first prototype. → AWS Activate.
11. A company wants a designated technical contact who proactively reviews its account health and escalates cases. → A TAM via Enterprise Support — a Support-plan feature, not a Solutions Architect.
12. A procurement officer needs evidence of a SaaS vendor’s security certifications before approving the purchase. → AWS Marketplace Vendor Insights.
If you got the Support-plan questions (6 and 11) and the Marketplace sub-features (4, 5, 12) right, you are at the level the exam needs. If the Professional Services versus AMS versus partner split (1, 2, 9) felt blurry, re-read those three sections — that is the most frequently tested distinction in this cluster.
Common Traps
- Professional Services ≠ Managed Services. Build/migrate project work versus ongoing operations.
- AWS Professional Services ≠ Marketplace Professional Services. AWS’s own consultants versus partner-delivered services listed in Marketplace.
- Solutions Architect ≠ Technical Account Manager. Account-team architecture advice versus a Support-plan operational advocate (Enterprise On-Ramp / Enterprise).
- re:Post is free and on Basic. Support cases for technical issues are not.
- Marketplace is for third-party products, not for AWS’s own services and not for hiring AWS employees.
- The Knowledge Center is part of re:Post, not a separate paid resource.
- AWS IQ no longer exists. Map it to Marketplace Professional Services.
- Trusted Advisor and the Health Dashboard are tools, not engagement models; see the Support plans guide for who gets which checks.
Turn Recognition Into Reflex
Every item in this article is a definition-plus-trigger-word pair, and the exam tests recognition under time pressure: roughly 65 questions in 90 minutes, which leaves well under 90 seconds per question. The way to make these distinctions automatic is to see them phrased a dozen different ways. Sailor.sh’s AWS Certified Cloud Practitioner (CLF-C02) Mock Exam Bundle gives you full-length, timed mock exams with explanations that spell out why AMS is right and Professional Services is the distractor, so Domain 4 becomes a place to bank points rather than lose them. Pair it with our CLF-C02 study plan and exam tips for the rest of your preparation.
Frequently Asked Questions
What is the difference between AWS Professional Services and AWS Managed Services?
AWS Professional Services is AWS’s consulting team, engaged for project work such as migrations, cloud-adoption programmes and data-platform builds. AWS Managed Services (AMS) is an ongoing operations service in which AWS runs your infrastructure — patching, backups, monitoring, incident and change management. One builds and moves; the other operates.
Is AWS Marketplace free to use?
Browsing and subscribing are free; you pay only the price each seller sets, which may include free trials, hourly, monthly, annual, multi-year or BYOL options. Charges appear on your AWS bill, and AWS pays the seller.
What is the AWS Partner Network and how do partner tiers work?
The AWS Partner Network (APN) is AWS’s programme for companies that build on or deliver AWS, organised into Software, Hardware, Services, Training and Distribution paths. Services-path partners (consultancies, MSPs) progress through Registered, Select, Advanced and Premier tiers based on certified staff, customer launches and customer satisfaction.
Is AWS re:Post the same as the AWS Knowledge Center?
The Knowledge Center — AWS’s library of troubleshooting and how-to articles — is now published inside re:Post. re:Post itself is the free, managed community Q&A service that replaced the AWS Forums and is available on every Support plan, including Basic.
What replaced AWS IQ?
AWS discontinued AWS IQ, with the service shutting down on May 28, 2026. Customers who want to hire certified experts for defined engagements are directed to Professional Services listings on AWS Marketplace, delivered by AWS Partner Network partners.
When should I use AWS Prescriptive Guidance versus the AWS Solutions Library?
Prescriptive Guidance provides strategies, implementation guides and reusable patterns for a specific scenario (for example, migrating a particular database engine). The Solutions Library provides vetted, deployable reference architectures, often with CloudFormation templates. Guidance tells you how; a Solution gives you something to deploy.
Do I get a Solutions Architect with every AWS account?
Account-team coverage, including Solutions Architect access, scales with your relationship and spend; large customers have named SAs, smaller ones work through shared teams. A Technical Account Manager is different and comes only with Enterprise On-Ramp (pooled) or Enterprise Support (designated).
Conclusion
The “who helps you” cluster of the CLF-C02 is small, but it is rich in near-identical names designed to be confused: Professional Services versus Managed Services versus Marketplace Professional Services, Solutions Architect versus Technical Account Manager, re:Post versus the Knowledge Center, Prescriptive Guidance versus the Solutions Library. Anchor each one to a single job — buy third-party software (Marketplace), engage a validated independent firm (APN), engage AWS’s consultants for a project (Professional Services), have AWS run your environment (AMS), get free community and curated answers (re:Post), follow a documented pattern (Prescriptive Guidance) — and note that AWS IQ has been retired in favour of Marketplace Professional Services. Then drill scenario questions until the trigger words do the work for you.
