Prove your AWS skills
Knowing service names is the easy part of AWS. Lemma looks at how you design, secure and debug real setups, through connected infrastructure code, live sessions and an adaptive assessment.

What AWS competence looks like
A competent AWS engineer picks services for reasons. They can explain why a workload fits Lambda better than containers, or why a managed database beats running their own. IAM policies follow least privilege, networking is deliberate, and nothing sits in a public bucket by accident.
They also run what they build. Infrastructure lives in code, so environments are reproducible. They set up alarms on what matters, read CloudWatch logs to find the real failure, and keep an eye on the bill. When something breaks at night, they know where to look first.

Practitioner · after the call
Clear reasoning on iam and least privilege. Talked through trade-offs first.
IAM and least privilege
Roles, policies and boundaries that grant exactly what each service needs, and nothing more.
Networking and VPCs
Subnets, routing, security groups and private connectivity designed to keep internal services off the internet.
Compute choices
Choosing between EC2, containers and Lambda based on workload shape, cost and operational effort.
Storage and databases
Using S3, DynamoDB and RDS appropriately, with backups, encryption and access patterns in mind.
Infrastructure as code
Defining resources with CloudFormation, CDK or Terraform so environments are reviewable and repeatable.
Monitoring and cost
CloudWatch alarms, logs and tracing, plus tagging and budgets that keep spending visible and explainable.
What counts as evidence of AWS skills?
Certificates in AWS show an exam was passed. Lemma records how you work: sessions where you talked through a design or an incident, an adaptive test, and configuration in repositories you link. Every entry says where it came from. See the evidence methodology for how each source is weighed.

Infrastructure code in a repository
Connect GitHub and attach a repository or commit with CloudFormation, CDK or Terraform you wrote. Lemma confirms the repo exists and your account can access it, then re-checks it periodically.
A live architecture walk-through
In a session, design or review an AWS setup with a practitioner: where traffic enters, how services talk, what fails first. Your reasoning about trade-offs is what they rate.
Diagnosing a policy or template
The adaptive assessment shows realistic situations, such as an IAM policy that grants too much or a template that will not deploy, and you pick the correct diagnosis or fix from the options.
Teaching IAM or networking
Teaching a session on least privilege or VPC design counts more than learning it. Explaining the why behind a policy is strong evidence of real understanding.
How is an AWS skills test run on Lemma?
The AWS test is adaptive, 15 to 25 questions on failure modes, permissions and cost rather than service names, and it stops once your level holds steady. With sessions and linked work it sets your AWS SCI, where recent evidence carries more weight.
A reporting job's IAM policy allows "s3:*" on "*". What is the right fix?
- AScope it to the bucket and actions it needs
- BAdd MFA to the role
- CMove the job to another region
- DRotate the access keys daily
Connect your infrastructure code
Attach GitHub repositories or commits where you defined AWS resources. Reviewers see that real infrastructure exists behind your claim, and Lemma keeps checking that the link is still valid.
Design a system in a live session
Book a session with an AWS practitioner and work through a design or an outage together. They probe your choices on IAM, networking and compute, then rate the session.
Take the adaptive AWS assessment
Scenario-based multiple-choice questions cover security, architecture and operations. Difficulty adjusts after each answer, harder questions count for more, and timed questions with no going back keep it honest.
