Problem Statement:

Our client needed to streamline and automate deployments for over 30 productive multi-tenant environments. Each tenant operated in its own AWS account, creating complexity in deployment management. Manual processes were time-consuming and error-prone. To solve this, they required a secure, scalable, and automated One-click Deployment system (learn more about AWS CI/CD).

Key challenges included:

• Complex Deployment Processes: Manual deployments across multiple AWS accounts led to inconsistencies and high error rates.

• Scalability Issues: The infrastructure had to scale effectively to support growing tenants.

• Security and Compliance: Needed secure deployments while maintaining isolation between client environments.

• Operational Overhead: A small SRE team managed deployments, making efficiency critical.

Proposed Solution & Architecture:

Unified Techs designed and implemented a CI/CD pipeline that automated and standardized deployments across all client environments. Using AWS services and AWS Cloud Development Kit (CDK) with TypeScript, we delivered a One-click Deployment capability that minimized manual work and reduced errors.

CI/CD Pipeline Flow Overview:

Architecture:

Continuous Integration (CI)

• Source Control: Bitbucket repository triggers the pipeline when code changes are committed.

• Testing: Bitbucket Pipelines runs unit tests, lint checks, and SonarQube static analysis.

• Artifact Creation: Packaged application code and AWS CDK resources are uploaded to a centralized S3 bucket.

Continuous Deployment (CD)

• One-click Deployment: AWS CodePipeline deploys the artifact to target environments upon upload to S3.

• Cross-Account Deployment: Securely manages deployments across 30+ AWS accounts using IAM roles and AWS CodeBuild.

• Environment-Specific Builds: Tailored configurations per client account ensure flexibility and compliance.

• Blast Radius Management: Environment-specific IAM roles limit deployment impact in case of failure.

Event-Driven Deployment Process

• Central AWS Account:

  • S3 triggers EventBridge when a new artifact is uploaded.

  • EventBridge forwards deployment events to the correct AWS account.

• Target AWS Account:

  • EventBridge triggers a Lambda function (assets_tracker_lambda) that starts AWS CodeBuild.

  • CodeBuild retrieves, extracts, and deploys the correct artifact version.

Metrics for Success:

• Deployment Time Reduction: 75% faster deployments using the One-click Deployment model.

• Error Rate: 90% fewer configuration and deployment errors.

• Consistency: 100% uniform deployments across all environments via AWS CDK and centralized artifacts.

• Operational Efficiency: A small SRE team now manages 30+ environments with minimal manual work.

Lessons Learned:

• Scalable Automation is Key: Automation across multiple AWS accounts reduces errors and overhead.

• Security Through Isolation: Distinct accounts and environment-specific IAM roles improve compliance and security.

• Centralized Artifact Management: Using S3 as a single source of truth ensures deployment consistency.

• One-click Deployment Improves Agility: A fully automated, single-action deployment process increases delivery speed and reduces human error.
