What you’ll learn

1. Design Secure Architectures 🛡️
Focuses on protecting AWS resources, applications, and data.

Secure Access: Implement IAM/Identity Center for federated access and least privilege. Understand the Shared Responsibility Model.

Secure Workloads: Secure application credentials/configuration, control network traffic, and use services like GuardDuty, Macie, and Cognito to mitigate DDoS/SQL injection threats.

Data Security: Apply controls for data governance, retention, recovery, and ensure strong encryption with proper key management.

2. Design Resilient Architectures 📈
Focuses on building scalable, loosely coupled, highly available, and fault-tolerant systems.

Scalability & Loose Coupling: Design microservices, event-driven patterns, and multi-tier systems. Utilize horizontal scaling, caching, load balancing, and services like API Gateway, SQS, Lambda, and ECS/EKS.

High Availability & Fault Tolerance: Leverage Regions/AZs. Define Disaster Recovery (DR) strategies (e.g., pilot light, warm standby) with clear RPO/RTO. Use immutable infrastructure and failover strategies.

3. Design High-Performing Architectures 🚀
Focuses on maximizing performance across the architecture.

Storage & Compute: Select high-performing storage services (S3, EFS, EBS) and compute services (Batch, EMR, Lambda) with appropriate scaling (Auto Scaling) and container orchestration.

Databases: Optimize performance using caching (ElastiCache), read replicas, and selecting the correct database types based on data access patterns.

Networking & Data: Design efficient network architecture (routing, subnets). Utilize edge networking (CloudFront, Global Accelerator) and select fast data ingestion/transformation services (Kinesis, Glue).

4. Design Cost-Optimized Architectures 💰
Focuses on minimizing costs while maintaining quality.

Cost Management: Use AWS cost management tools (Cost Explorer, Budgets) for all services.

Storage & Compute Optimization: Implement storage tiering and data lifecycles. Utilize cost-effective purchasing options (Spot Instances, Savings Plans) and optimize resource utilization with serverless/containers.

Databases & Networking: Optimize database costs with caching and efficient capacity planning. Evaluate network costs, such as the difference between NAT instance and NAT Gateway costs.
