AWS Certified Developer - Associate

The certification encourages candidates to understand the purpose of AWS services and make appropriate architecture decisions instead of simply memorizing service definitions.

AWS Cloud Fundamentals

Before designing cloud solutions, learners should understand the fundamental concepts of cloud computing. Cloud computing allows organizations to access computing resources over the internet without owning and maintaining all physical infrastructure themselves.

AWS provides resources that can be provisioned according to demand. Organizations can increase or decrease resources based on workload requirements, helping them achieve flexibility and scalability.

Important AWS concepts include Regions, Availability Zones, scalability, elasticity, fault tolerance, high availability, and shared responsibility.

Understanding these concepts provides the foundation required to design effective AWS architectures.

Core AWS Services

The certification covers several major AWS services that are commonly used in cloud architectures.

Amazon EC2 provides virtual computing resources for running applications and workloads. Architects need to understand instance types, storage, security, scaling, and workload requirements when selecting EC2 resources.

Amazon S3 provides scalable object storage for files, backups, application data, media, logs, and other objects. Storage classes and lifecycle management can help organizations manage data efficiently.

Amazon RDS provides managed relational database capabilities, while Amazon DynamoDB provides a managed NoSQL database solution for applications requiring flexible and scalable data storage.

Amazon VPC allows organizations to create logically isolated networks and control communication between cloud resources.
