Background

Project Overview

StarzHD set out to modernize its infrastructure by migrating mission-critical applications from on-premises environments to AWS, while significantly improving availability, resilience, and operational control. CyberHULL partnered with StarzHD to redesign their cloud architecture, introduce secure environment separation across AWS accounts, and implement a robust multi-region failover strategy — ensuring uninterrupted service delivery even under regional outages.

Cloud Migration

Migrating legacy on-premises applications to the cloud without service disruption.

Environment Separation

Separating environments across multiple AWS accounts to improve security and governance.

Cross-Account Communication

Enabling secure, private communication between services deployed in different AWS accounts.

Multi-Region Failover

Implementing a reliable multi-region failover strategy with controlled traffic distribution.

Deployment Strategies

Supporting modern deployment strategies (Blue-Green / Canary) without increasing operational risk.

Operational Readiness

Ensuring full observability, documentation, and operational readiness for production scenarios.

Solutions

Our strategic approach to solving each challenge with precision and expertise.

Cloud Migration & Environment Separation

Conducted deep architectural review of existing services and dependencies

Refactored infrastructure following modern security, reliability, and cloud-native best practices

Provisioned isolated environments across separate AWS accounts for stronger security boundaries

Implemented Infrastructure as Code (IaC) for consistent, repeatable environment creation

Deployment & Release Engineering

Designed and implemented CI/CD pipelines supporting Blue-Green and Canary deployments

Enabled safe environment promotion from development through production

Actively supported production switchover with minimal end-user impact

Secure Cross-Account Communication

Built scalable and secure private communication layer between services across AWS accounts

Ensured encrypted traffic, controlled access, and fault isolation

Documented service interactions, workflows, and dependencies with clear architecture diagrams

Multi-Region Failover Architecture

Designed and deployed multi-region failover solution across all application stacks

Implemented traffic distribution strategies tailored per application

Enabled controlled regional traffic shifting during failover scenarios

Validated failover behavior through testing and operational drills

Observability & Documentation

Implemented advanced monitoring with metrics, dashboards, and alerting

Enabled visibility into service health, availability, and regional traffic distribution

Delivered comprehensive documentation covering infrastructure setup, workflows, and failover scenarios
