Cloud Security Migration
Zero-Trust Cloud Architecture
Project Overview
Led the security architecture and implementation for migrating critical government services from on-premises data centers to a hybrid cloud environment. The project required meeting stringent government security standards while enabling modern cloud capabilities.
The Challenge
The government agency needed to modernize their infrastructure while maintaining strict security controls. Legacy applications required careful assessment for cloud readiness. Compliance with government security frameworks was mandatory, and the migration needed to occur with zero downtime for critical public services.
The Solution
I designed a zero-trust security architecture leveraging Azure and AWS services. This included implementing conditional access policies, network micro-segmentation, and comprehensive identity management using Azure AD. Infrastructure as Code using Terraform ensured consistent, auditable deployments. Azure Sentinel was deployed for cloud-native security monitoring.

- Government security framework compliance
- Zero-trust architecture implementation
- Zero downtime during migration
- Data sovereignty requirements
- Multi-factor authentication for all access
- Encryption at rest and in transit
- Comprehensive audit logging
- Disaster recovery with RPO < 1 hour
