AWS Certified Developer - Associate

Understanding these services and their use cases is essential for AWS Solutions Architect preparation.

AWS Networking

Networking is a critical part of cloud architecture. Amazon VPC provides the foundation for creating private cloud networks within AWS.

Candidates learn about public and private subnets, route tables, internet gateways, NAT gateways, security groups, and network access control lists.

For example, a web application may have public-facing components that require internet access, while database resources can be placed in private subnets for additional protection.

Understanding network traffic flow and security controls helps architects design secure and reliable cloud environments.

Security and Identity Management

Security is an essential consideration when designing AWS solutions. AWS Identity and Access Management helps organizations control access to cloud resources.

Candidates learn about IAM users, roles, policies, permissions, and the principle of least privilege. Applications and users should receive only the permissions required to perform their tasks.

AWS architecture also involves encryption, network security, monitoring, logging, and data protection. Security should be incorporated into the architecture from the beginning rather than treated as an afterthought.

High Availability and Reliability

Modern applications need to remain available even when individual infrastructure components experience failures. AWS provides several capabilities that help organizations design highly available solutions.
