A prominent Singapore digital media and technology company engaged 1CLOUDSTAR to enhance governance, security, and performance within its AWS cloud environment. The customer sought to segregate production and UAT workloads, modernize its architecture, and establish continuous cloud monitoring under a managed services framework.

The customer operated multiple workloads within a shared AWS account, creating several operational challenges:

• No clear separation between production and UAT workloads, posing security and stability risks.
• Manual resource provisioning and lack of standardized policies for governance.
• Limited visibility into network flow, performance, and compliance.
• High administrative overhead in maintaining infrastructure and responding to incidents.

1CLOUDSTAR implemented a comprehensive AWS Control Tower landing zone to enable multi-account governance, standardized policies, and secure workload separation.

• AWS Control Tower Implementation
  Established a governed landing zone with dedicated accounts for Production and UAT workloads, integrating AWS Organizations, AWS Config, and Control Tower Guardrails for compliance and automation.
• Production & UAT Migration
  Migrated both environments into their respective AWS accounts under Control Tower, ensuring isolation, optimized performance, and enhanced governance.
• Network and Security Enhancements
  Integrated Palo Alto Next-Generation Firewalls (NGFW) for perimeter security and AWS Transit Gateway for simplified inter-VPC routing. Deployed AWS CloudWatch and Systems Manager to enable real-time visibility, event automation, and centralized management.
• Identity & Access Control
  Configured AWS Cognito and integrated Azure Entra ID (SSO) to streamline secure access and user authentication.
• 24x7 Managed Services
  The entire AWS environment was transitioned into 1CLOUDSTAR’s CloudTrack Managed Services program, providing proactive monitoring, OS-level patching, monthly reporting, and incident response aligned with SLA-driven performance.

This architecture unified governance, enhanced visibility, and optimized the customer’s AWS operations end to end.

• Fully segregated Production and UAT environments with centralized account governance.
• Strengthened security through NGFW integration, policy guardrails, and continuous compliance monitoring.
• Improved operational visibility and automation via CloudWatch and Systems Manager.
• 24x7 managed services reduced downtime and ensured ongoing reliability and optimization.

This modernized AWS environment enabled the customer to operate with greater security, agility, and cost efficiency.

A global hospitality enterprise operating more than 50 hotels and resorts across Asia Pacific, North America, Africa, and Europe engaged 1CLOUDSTAR to lead its multi-phase cloud migration initiative. The organization sought to centralize IT management, modernize its infrastructure, and leverage AWS to improve scalability, security, and global governance.

• Disparate infrastructure across geographies, leading to inconsistent performance and management.
• Aging systems and unsupported operating environments
• High maintenance costs and limited visibility across global assets.
• Need for centralized Active Directory (AD) management and compliance with global security standards.
• Urgent requirement to modernize while maintaining 24x7 business operations across hotels and offices.

1CLOUDSTAR, as the appointed AWS Partner, executed a comprehensive cloud transformation roadmap

• Deep Discovery and Assessment
  A global deep discovery was conducted to analyze infrastructure dependencies, database utilization, and workload readiness. Using AWS Migration tools, 1CLOUDSTAR assessed more than 70 properties across 14 countries, providing right-sizing, cost optimization, and a detailed Total Cost of Ownership (TCO) plan.
• AWS Control Tower & Landing Zone Design
  A multi-account Control Tower landing zone was deployed in Singapore to establish secure governance and compliance guardrails across all future AWS environments.
  Shared accounts for security, logging, and management were implemented.
  Audit accounts were configured for centralized compliance monitoring.
  AWS Organizations, Config, and Security Hub were integrated to automate policy enforcement and reporting.
• Active Directory Consolidation
  A new centralized Active Directory Forest was established on AWS with Read-Only Domain Controllers (RODCs) in regional VPCs, achieving single-domain identity management across all corporate and property sites.
  Integration with Azure AD Connect enabled seamless hybrid authentication and improved global identity governance.
• Pilot Migration
  1CLOUDSTAR executed a pilot migration of 31 servers and applications, including corporate systems, property management workloads, and firewalls in Singapore, Australia, and the UK.
  Rehost and replatform strategies were applied using EC2, RDS, and AWS Backup.
  A Business Continuity Plan (BCP) was tested with multi-region failover for resilience and disaster recovery validation.
• Security & Compliance Framework
  A shared security model was implemented following AWS best practices:
  GuardDuty, Security Hub, CloudTrail, and KMS enabled continuous compliance monitoring.
  Data encryption at rest and in transit was enforced.
  IAM roles and policies were aligned with the principle of least privilege.
  AWS WAF and NGFW integrations were used to enhance perimeter protection.
• Operations & Knowledge Transfer
  The project concluded with the setup of a Cloud Center of Excellence (CCoE), extensive training for the customer’s IT teams, and full documentation for governance and SOP alignment. Ongoing operations are managed under 1CLOUDSTAR’s CloudTrack Managed Services.
