This lesson explains how the AWS Well-Architected Framework (WAF) is applied to e-commerce microservices. Each microservice is evaluated through the lens of the six WAF pillars—Operational Excellence, Security, Reliability, Performance Efficiency, Cost Optimization, and Sustainability—focusing on AWS Services Used, Design Principles, and Implementation for each pillar. The goal is to showcase a comprehensive approach to building scalable, secure, and high-performing microservices.
Operational Excellence:
Focuses on automating operations, monitoring system health, and managing changes efficiently.
Explains the use of AWS services such as CloudWatch, X-Ray, and CodePipeline to support proactive monitoring, deployment automation, and tracing.
Outlines design principles like infrastructure-as-code, proactive monitoring, and incident preparedness.
Implementation highlights include CI/CD pipelines, distributed tracing, and operational runbooks.
Security:
Covers the protection of data, workloads, and infrastructure against threats.
Describes how AWS services such as IAM, KMS, VPC Endpoints, and AWS WAF are used for encryption, access control, and threat detection.
Design principles emphasize least privilege access, network isolation, and continuous security monitoring.
Implementation details include fine-grained IAM policies, data encryption with KMS, and private networking through VPC endpoints.
Reliability:
Explores strategies for ensuring high availability and fault tolerance across microservices.
Details AWS services like DynamoDB Global Tables, S3 Versioning, and ECS Fargate for data durability, fault tolerance, and elastic scaling.
Design principles focus on failover readiness, data integrity, and resilience testing.
Implementation examples include multi-region replication, disaster recovery drills, and S3 versioning for product data.
Performance Efficiency:
Focuses on delivering high throughput and low latency for e-commerce services.
Highlights AWS services like ElastiCache, OpenSearch, and DynamoDB Auto-Scaling to optimize data retrieval and search operations.
Design principles include resource right-sizing, efficient data retrieval, and monitor-and-adjust strategies.
Implementation includes caching frequently accessed data, load testing, and optimizing OpenSearch indices.
Cost Optimization:
Provides strategies for balancing performance and resource usage while reducing costs.
Explains how services like DynamoDB On-Demand, S3 Intelligent-Tiering, and Spot Instances help manage costs.
Design principles emphasize pay-for-use models, continuous optimization, and cost visibility.
Implementation covers the use of DynamoDB on-demand mode, S3 tiered storage, and regular cost audits with AWS Trusted Advisor.
Sustainability:
Highlights efforts to reduce the environmental impact of running workloads.
Discusses services like AWS Graviton2 and S3 Lifecycle Policies for energy efficiency and storage optimization.
Design principles include energy-efficient compute, data minimization, and resource optimization.
Implementation involves migrating to Graviton2 instances, archiving unused data with S3 lifecycle policies, and optimizing resource utilization.
