This diagram illustrates a comprehensive cloud architecture that integrates security, development, and operations in a modern DevSecOps approach. The architecture shows how different environments are organized and connected, with a strong focus on security and access control.
Key Components of the Architecture
Account Structure
The architecture is divided into several AWS accounts:
Security/Administration Account: Houses the Vault for secrets management
Development Account: Contains IAM roles, various development tools (GitLab, Artifactory, Jenkins)
VPC Flow Logs: Captures network traffic data for monitoring
At the center of the architecture is a multi-tier environment with:
Public and private subnets with clearly defined security zones
NAT Gateways for outbound connections
EC2 instances organized by security groups
Load balancers controlling traffic flow
Multiple availability zones for high availability
Security Features
Security is deeply integrated throughout:
VPN Client for secure remote access
Certificate Manager for TLS/SSL management
IAM roles for granular permission control
Security groups defining network access controls
Vault for secrets management
User Access
The diagram shows multiple access paths:
Mobile clients connecting through API Gateway
Developer access through secure VPN
Customer Gateway for external partner connections
TransitGateway for network connectivity between VPCs
Monitoring and Communication
The right side shows:
Monitoring tools like CloudWatch
Communication tools including Slack, Microsoft Teams, and email
Alerts flowing from monitoring systems to communication channels
Benefits of This Architecture
This architecture demonstrates several modern cloud best practices:
Strong security through isolation (separate accounts for different purposes)
High availability with redundant components across availability zones
Centralized monitoring and logging
Secure access paths for different user types
Integration of development tools with CI/CD pipeline capability
The design allows development teams to work efficiently while maintaining security controls and ensuring operational visibility. The separation between environments provides important isolation between workloads while still enabling necessary communication between systems.
By implementing this architecture, organizations can achieve a balance between development agility, operational stability, and security compliance – the three core pillars of DevSecOps methodology.
