Worklog Week 12

Week 12 Objectives:

  • Event-Driven Architecture (EDA): Integrate Amazon SQS to buffer and decouple high-volume image processing tasks.
  • Resiliency: Implement asynchronous processing patterns to handle traffic spikes without dropping requests.
  • Production Readiness: Finalize Domain/DNS configuration, SSL certificates, and Operational Monitoring (SNS).
  • Complete the main interfaces of the Frontend, prepare for domain name purchase, and attend the final AWS Cloud Mastery Series event.

Tasks to be Deployed This Week:

DayTaskStart DateCompletion DateResources
Mon- Feature Logic- Completed complex logic for UpdateArticle (handling concurrency and partial updates).
- Tuned Rekognition MinConfidence thresholds to improve tag relevance.		25/11/202525/11/2025
Tue- Async Pattern- Architectural Upgrade: Refactored the AI pipeline to the Storage-First Pattern:
Upload to S3 $\rightarrow$ S3 Event $\rightarrow$ SQS Queue $\rightarrow$ Lambda Worker $\rightarrow$ DynamoDB.
- Benefit: Provides a “buffer” to protect downstream services from throttling.		27/11/202527/11/2025
WedGeo-Location- Integrated Map Pinning on the frontend.
- Modeled geospatial data (Latitude/Longitude) in DynamoDB for future geospatial queries.		27/11/202527/11/2025
Thu- Observability- Deployed Amazon SNS topics to alert administrators on critical system failures (CloudWatch Alarms).
- Audited IAM Roles to ensure “Least Privilege” before public release.		28/11/202528/11/2025
Fri- Go-Live Prep- Configured Route 53 Alias records to point the custom domain to CloudFront (Frontend) and API Gateway (Backend).
- Provisioned SSL/TLS certificates via AWS Certificate Manager (ACM) for HTTPS security.		29/11/202529/11/2025

Week 12 Achievements:

  • Resilient System: The introduction of SQS created a robust Event-Driven Architecture capable of handling burst traffic without failure.
  • Enterprise Standard: The system now features a complete serverless lifecycle: Compute (Lambda), Storage (S3), Database (DynamoDB), Integration (SQS/SNS), and Network (Route53).
  • Demo Ready: The project is fully deployed, secured with HTTPS, and operates under a professional CI/CD and Multi-stack infrastructure.
  • Successfully participated in the final AWS Cloud Mastery Series event, receiving comprehensive guidance for project completion.
  • The project has reached Demo Readiness status.
