AWS Certification Guide 2026: Which Cert to Get and How to Prepare

AWS Certification Overview

AWS (Amazon Web Services) certifications are credentials issued by Amazon that validate expertise in cloud computing services on the AWS platform. As the world's largest cloud provider — with over 30% market share globally — AWS certifications are among the most recognized and valued credentials in the technology industry. Professionals with AWS certifications consistently earn above-average salaries, and employers ranging from startups to Fortune 500 companies actively seek AWS-certified candidates for cloud engineering, architecture, DevOps, security, and operations roles.

AWS offers 12 active certifications organized into four levels: Foundational, Associate, Professional, and Specialty. The certification path is generally sequential — most candidates begin with the AWS Certified Cloud Practitioner (foundational level) or an Associate-level certification and progress to higher levels as they gain experience. However, there are no mandatory prerequisites — you can attempt any AWS certification at any time, though practical experience and progression through lower-level exams typically improves your success rate on higher-level exams.

All AWS certifications are valid for three years. To maintain an active certification, you must recertify before expiration by passing the current version of the exam. AWS updates its exam content periodically to reflect the evolving AWS service catalog — staying current with AWS service launches and exam version updates is important for maintaining your credentials and ensuring your knowledge reflects the current AWS environment.

AWS Foundational Certification

AWS Certified Cloud Practitioner (CLF-C02)

The AWS Certified Cloud Practitioner is the entry-level AWS certification and the recommended starting point for most individuals new to cloud computing or AWS. It is designed for non-technical business professionals, students, and technical professionals who want to understand AWS services, cloud concepts, pricing, security, and architecture at a foundational level. No prior technical experience is required, though familiarity with basic IT concepts is helpful.

The Cloud Practitioner exam (CLF-C02) consists of 65 questions in a 90-minute time limit, with a minimum passing score of 700 out of 1000. The exam covers four domains: Cloud Concepts (26%), Security and Compliance (25%), Cloud Technology and Services (33%), and Billing, Pricing, and Support (16%). Common AWS services tested include EC2, S3, RDS, Lambda, VPC, IAM, and CloudWatch.

The Cloud Practitioner is valuable as a credential in its own right for business-facing roles — cloud sales, account management, project management — and as preparation for Associate-level technical certifications. Most candidates with one to three months of study pass the exam on their first attempt. Recommended preparation resources include the official AWS Cloud Practitioner Essentials course (free on AWS Skill Builder), AWS Certified Cloud Practitioner Foundational practice question sets, and third-party resources from Stephane Maarek, Adrian Cantrill, or A Cloud Guru.

AWS Associate-Level Certifications

Associate certifications are the most popular entry points for technical professionals pursuing AWS credentials. They validate practical knowledge of specific AWS domains and are widely recognized by employers as evidence of real-world AWS competency.

AWS Certified Solutions Architect – Associate (SAA-C03)

The Solutions Architect – Associate is the most popular AWS certification by exam volume. It validates your ability to design distributed applications and systems on AWS, covering topics including compute services (EC2, Lambda), storage (S3, EBS, EFS), databases (RDS, DynamoDB), networking (VPC, Route 53, CloudFront), security (IAM, KMS), and architectural best practices from the AWS Well-Architected Framework. The exam has 65 questions, 130-minute time limit, and requires a minimum score of 720 out of 1000. Recommended for developers, architects, and engineers who work with or design AWS infrastructure.

AWS Certified Developer – Associate (DVA-C02)

The Developer – Associate validates your ability to develop and maintain applications on AWS, including expertise in AWS SDKs, Lambda, API Gateway, DynamoDB, SQS, SNS, Elastic Beanstalk, and CI/CD services like CodePipeline and CodeDeploy. This certification is ideal for software developers who build AWS-native applications. The exam format is similar to the Solutions Architect – Associate (65 questions, 130 minutes, 720 passing score).

AWS Certified SysOps Administrator – Associate (SOA-C02)

The SysOps Administrator – Associate validates operational skills for managing and deploying applications on AWS, covering monitoring, automation, security operations, networking, and cost optimization. Uniquely, the SOA-C02 exam includes a lab section where candidates must complete hands-on tasks in an actual AWS environment in addition to multiple-choice questions. This makes it somewhat more challenging to prepare for than the other Associate certifications. Recommended for system administrators, cloud operations engineers, and DevOps professionals.

Professional and Specialty AWS Certifications

Professional Level

Professional-level certifications validate advanced technical skills and typically require one to two years of hands-on AWS experience beyond what is tested at the Associate level. The two Professional certifications are:

• AWS Certified Solutions Architect – Professional (SAP-C02): The most challenging and prestigious of the AWS certifications. Validates complex, multi-account AWS architectures, migration strategies, and advanced design patterns. Required by many senior cloud architect roles at enterprise companies. 75 questions, 180-minute time limit, 750 passing score.
• AWS Certified DevOps Engineer – Professional (DOP-C02): Validates expertise in continuous delivery pipelines, infrastructure as code, monitoring, security automation, and high availability patterns on AWS. Required for senior DevOps and platform engineering roles.

Specialty Certifications

AWS Specialty certifications validate deep expertise in specific domains. Current Specialty certifications include:

• AWS Certified Security – Specialty (SCS-C02): Data protection, incident response, and security compliance on AWS
• AWS Certified Machine Learning – Specialty (MLS-C01): Designing, building, and deploying ML solutions using Amazon SageMaker and related services
• AWS Certified Advanced Networking – Specialty (ANS-C01): Complex networking architectures, hybrid connectivity, and DNS
• AWS Certified Data Analytics – Specialty (DAS-C01): Data collection, storage, processing, and visualization on AWS
• AWS Certified Database – Specialty (DBS-C01): Database migration and management on AWS
• AWS Certified SAP on AWS – Specialty (PAS-C01): Designing and deploying SAP workloads on AWS

How to Study for AWS Certifications

Effective AWS certification preparation combines video-based learning, official AWS documentation, hands-on lab practice, and exam-style practice questions. Here is a recommended preparation framework:

Use AWS Skill Builder (Free and Paid)

AWS Skill Builder is Amazon's official learning platform at skillbuilder.aws. It includes free courses for all certification levels, the official AWS Certified Cloud Practitioner Essentials course, and a paid subscription tier (AWS Skill Builder Individual at $29/month) that provides access to official practice exam question sets. The official practice questions most closely reflect the actual exam's difficulty, phrasing, and topic distribution.

Follow a Structured Video Course

Third-party courses from instructors Stephane Maarek (on Udemy), Adrian Cantrill (at cantrill.io), and A Cloud Guru provide structured learning paths that explain AWS services from first principles and connect them to real-world scenarios. These courses typically include hands-on labs where you provision actual AWS resources — this hands-on practice is critical because AWS exam questions often test understanding of service behavior and architecture, not just definition-level knowledge.

Practice with Mock Exams Until You Consistently Score 80%+

Most candidates who pass AWS certifications on their first attempt report achieving consistent practice exam scores of 80% or above before sitting for the real exam. The actual passing score is 700 to 750 (out of 1000 scaled score), which typically corresponds to roughly 70% of questions correct — the 80% practice threshold provides a comfortable safety buffer for the real exam's question phrasing variations.

Hands-On Lab Practice is Non-Negotiable

AWS exams consistently reward candidates who have hands-on experience with the services being tested. Creating an AWS free-tier account and building the architectures described in your study materials — launching EC2 instances, configuring S3 buckets with policies, setting up VPCs with subnets and security groups — produces a depth of understanding that purely passive study cannot replicate. Most incorrect answers on AWS exams result from incomplete mental models of how services actually behave, which hands-on practice resolves.
