AWS Academy Lab Ready & Self-Contained Demo

Demo Mode available without cloud credentials. Full AWS services activate automatically when environment variables are supplied.

DevOps Architecture & Delivery

Automated CI/CD Delivery Pipeline

TaskFlow automates every code push through AWS Academy-compatible services: validating sprint commits, compiling serverless assets, and propagating updates to global edge caches.

STAGE 01
Active

Version Control

GitHub / AWS CodeCommit

Sprint branch merges trigger automated webhook validation and build artifact packaging.

Webhook Latency42ms
git push origin main
STAGE 02
In Progress

Continuous Build

AWS CodeBuild

Serverless container builds run unit tests, TypeScript compilation, and security linting in isolated environments.

Build Duration1m 48s
codebuild:buildspec.yml
STAGE 03
Validated

Artifact Persistence

Amazon S3 & DynamoDB

Compiled SPA assets sync to private S3 buckets while data models and migrations commit to DynamoDB tables.

Integrity Check100%
