The AWS Certified Developer – Associate certification validates your ability to develop, deploy, and troubleshoot cloud-based applications using AWS. This course provides a structured and hands-on approach to mastering AWS development concepts, from fundamental tools like AWS SDKs, IAM, and CloudFormation to serverless computing, event-driven architectures, and CI/CD automation. You'll gain practical experience with databases, caching solutions, and security best practices while optimizing applications for performance, scalability, and cost efficiency. The course also includes real-world scenarios and curated practice exam questions to help you confidently pass the certification exam. Whether you're a developer new to AWS or looking to formalize your knowledge, this course provides the essential skills needed to build modern cloud applications.

This course is designed for developers who want to build, deploy, and optimize applications on AWS. Specifically, it benefits: Software Developers, DevOps & Cloud Engineers, Solution Architects (with Developer Focus), and Tech Leads & Engineering Managers

Get an overview of the AWS Certified Developer – Associate certification, including its purpose, benefits, and ideal candidates. Understand the exam format, domains, and knowledge areas tested. Learn about key prerequisites and how this course is structured to help you build AWS development expertise step by step.

Learn how to interact with AWS programmatically using AWS SDKs, CLI, and authentication mechanisms like IAM roles and Amazon Cognito. Explore Infrastructure as Code (IaC) tools like AWS CloudFormation, AWS CDK, and AWS SAM, understanding when to use declarative vs. programmatic approaches.

We'll dive into AWS databases and caching solutions to design high-performance, cost-efficient applications. Learn to model NoSQL databases with Amazon DynamoDB, optimize queries, and use DynamoDB Streams for real-time processing. Explore Amazon RDS and Aurora, focusing on scalability, high availability, and failover strategies. Finally, we'll look into improving application responsiveness with Amazon ElastiCache (Redis, Memcached) and DynamoDB Accelerator (DAX) for caching and in-memory data storage.

Learn to build and deploy serverless applications using AWS Lambda, optimizing performance and execution costs. Explore event-driven architectures by integrating applications with Amazon SQS, SNS, and EventBridge for asynchronous communication and automation. You'll also learn to orchestrate serverless workflows using AWS Step Functions, ensuring scalability and fault tolerance. This section will enable you to design highly responsive, scalable applications using AWS-native serverless tools.

Automate application development and deployment using AWS CI/CD tools, including AWS CodeCommit, CodePipeline, CodeBuild, and CodeDeploy. Learn to implement different deployment strategies to ensure reliability and minimize downtime. After that, we'll look at some best practices for migrating existing applications to AWS, refactoring them to leverage AWS-native features for better performance and scalability by exploring a few real-world scenarios.

Implement effective monitoring and debugging using AWS CloudWatch, AWS X-Ray, and centralized logging. Learn how to secure AWS applications with AWS Secrets Manager, Parameter Store, and KMS encryption, while protecting APIs with API Gateway security features, AWS WAF, and AWS Shield. This section ensures your applications are secure, well-monitored, and optimized for reliability and performance.
