A leading regional digital media company operating mission-critical digital platforms in Singapore sought to modernize its AWS operating model to improve governance, security, and operational efficiency as its cloud footprint scaled.

1Cloudstar engaged the customer through multiple discovery and working sessions to understand governance gaps, operational challenges, and CloudOps success criteria. These discussions covered environment separation strategy, access controls, monitoring and alerting requirements, patching cadence, incident response expectations, and cost visibility.
The outcome of these sessions defined a target CloudOps operating model aligned with AWS best practices and the customer’s operational objectives.

Prior to engaging 1Cloudstar, both UAT and Production workloads were hosted within a single AWS account. This created compliance and governance risks, limited cost visibility, and made it difficult to enforce consistent security controls and operational standards.

Manual provisioning and patching resulted in configuration drift, inconsistent security baselines, and longer recovery times during incidents. As the environment scaled, operational overhead and audit complexity increased.

Based on the discovery outcomes, 1Cloudstar designed and implemented a CloudOps framework centered on AWS Control Tower, establishing a governed multi-account architecture with clear separation between UAT and Production environments. Preventive and detective guardrails were applied to enforce security and compliance aligned with AWS best practices.

Infrastructure provisioning was standardized using AWS CloudFormation, enabling consistent patterns across environments and reducing configuration drift. AWS Systems Manager was used to define patching scope, maintenance schedules, and operational hygiene.

Amazon CloudWatch centralized monitoring, logging, and alerting, with thresholds and MTTR expectations jointly defined. AWS Security Hub and Amazon GuardDuty consolidated security findings to support continuous compliance and threat visibility. As part of the access governance design, 1Cloudstar worked with the customer to define an identity and access model aligned with operational requirements. Microsoft Entra ID was integrated with AWS IAM using SCIM-based provisioning to automate user and role synchronization, reducing manual administration while ensuring consistent access controls across environments.

Following implementation, the customer gained direct visibility into its AWS environments, enabling internal teams to actively monitor resource utilization and cost consumption.

1CLOUDSTAR delivered monthly resource-level utilization reports and conducted regular review sessions to identify optimization opportunities such as instance rightsizing and evaluation of AWS purchasing options. These efforts resulted in:

• 40% reduction in mean time to recovery (MTTR)
• 60% faster deployment cycles
• 50% faster resolution of security findings
• 25% reduction in cost per workload

Operational KPIs and alert thresholds were jointly defined, supporting proactive monitoring and faster response times. The engagement significantly improved governance, operational efficiency, and compliance across environments.

Throughout the engagement, 1CLOUDSTAR conducted walkthroughs during kickoff and implementation phases to explain the CloudOps operating model, monitoring approach, and incident escalation processes.

Architecture diagrams, support SOPs, managed services scope, and Infrastructure-as-Code templates were shared and reviewed with the customer to support knowledge transfer and operational understanding.

Post-go-live review sessions enabled the customer’s internal teams to progressively take ownership of day-to-day cloud operations while continuously improving cost efficiency and operational maturity.

By transitioning from a single, unmanaged AWS account to a secure, automated, and well-governed multi-account framework, the customer established a strong CloudOps foundation. The solution provides scalability, resilience, and visibility to support ongoing growth while maintaining compliance and operational excellence on AWS.

A leading international hospitality group operating more than 50 hotels across Asia-Pacific sought to modernize its IT operations by moving away from decentralized, property-managed infrastructure to a standardized and centrally governed cloud operating model on AWS.

1CLOUDSTAR engaged the customer through structured discovery and working sessions to understand regional operating models, governance challenges, and CloudOps success criteria.

These sessions focused on account structure, identity and access governance, monitoring and alerting requirements, patching cadence, incident response processes, disaster recovery readiness, and cost visibility across regions.

Prior to the transformation, each hotel property operated its own on-premises servers and applications. This decentralized model resulted in inconsistent patching, fragmented monitoring, rising maintenance costs, and limited visibility across environments.

Without centralized governance, the IT team struggled to enforce security policies, scale efficiently as new properties were added, and maintain consistent operational standards across regions. Compliance risks increased, and operational overhead continued to grow.

Based on the discovery outcomes, 1CLOUDSTAR designed and implemented a global CloudOps framework using AWS Control Tower as the foundation for centralized governance. A secure multi-account architecture was established to support regional autonomy while enforcing global standards through preventive and detective guardrails aligned with AWS best practices.

Joint working sessions were conducted to define the Active Directory and server migration approach, including identity architecture, domain structure, and integration strategy. This ensured that the resulting design supported consistent identity governance, operational ownership, and long-term scalability across regions.

An architectural assessment was performed using the AWS Well-Architected Tool, reviewing operational excellence, security, reliability, performance efficiency, and cost optimization. Findings were reviewed collaboratively and incorporated into the final implementation.

Infrastructure provisioning was standardized using AWS CloudFormation, enabling reusable patterns across regions and environments. AWS Systems Manager was used to define patching scope, maintenance schedules, and operational hygiene. Amazon CloudWatch centralized monitoring, logging, and alerting, with MTTR expectations and alert thresholds jointly defined.

AWS Security Hub and Amazon GuardDuty provided centralized security visibility and continuous compliance monitoring.

The solution was delivered in two phases:

• Phase 1: Singapore and Australia
• Phase 2: Southeast Asia

This phased approach enabled controlled rollout, validation, and regional onboarding while maintaining operational stability.

Throughout the engagement, 1CLOUDSTAR conducted walkthroughs during kickoff, implementation, and post-migration phases to explain the CloudOps operating model, monitoring approach, incident escalation procedures, and cost optimization strategies.

Architecture diagrams, runbooks, playbooks, Infrastructure-as-Code templates, and operational SOPs were shared and reviewed with the customer. Disaster recovery drills were also conducted to validate readiness and improve operational confidence.

These activities enabled the customer’s internal teams to progressively take ownership of day-to-day cloud operations while continuing to improve efficiency and resilience.

By moving from a decentralized on-premises model to a standardized and governed AWS CloudOps framework, the customer established a secure and scalable foundation to support global growth and long-term operational excellence.
