OVERVIEW

A leading financial guarantee institution in Cambodia that provides innovative credit guarantees to businesses to improve financial inclusion and contribute to country’s economic growth and plays a pivotal role in strengthening the country’s financial services ecosystem. As this Cambodian credit guarantor’s digital services continued to expand, the organization recognized the need for a more resilient and flexible disaster recovery (DR) solution to ensure business continuity and safeguard its mission-critical systems against potential disruptions.

To meet these needs and establish a secure, scalable disaster recovery (DR) solution while preparing for future cloud adoption, Cambodian credit guarantor partnered with Renova Cloud to design and implement a modern cloud-native DR architecture on Amazon Web Services (AWS). This successful collaboration enabled the company to achieve high system availability, optimize operational costs, and build a strong foundation for ongoing digital growth.

KEY CHALLENGES

The Cambodian credit guarantor operates a wide range of core business applications and Kubernetes-based workloads entirely on-premises, with no existing disaster recovery site or failover mechanism.

As the organization’s operations became more digitized and interconnected, the following challenges emerged:

  • No DR site or failover mechanism for mission-critical systems and containerized workloads.
  • High capital expenditure required to build and maintain traditional on-prem DR infrastructure.
  • Growing concerns over system vulnerability to outages, hardware failures, and potential cyber threats.
  • Need for a secure, scalable, and future-proof DR solution that enables seamless transition towards full cloud adoption.

SOLUTION

To help the company achieve its business continuity and modernization goals, Renova Cloud designed a robust, scalable DR solution fully integrated with AWS cloud-native services.

Architecture & Deployment

The solution included:

  • AWS Virtual Private Cloud (VPC) and Transit Gateway: Providing secure network isolation with hybrid cloud connectivity between on-premises systems and AWS.
  • AWS Site-to-Site VPN: Establishing private, encrypted network communication between existing data centers and the AWS environment.
  • Elastic Load Balancer & Route 53: Facilitating intelligent traffic routing and load balancing for seamless failover.
  • Amazon EKS (Elastic Kubernetes Service) & Amazon ECR (Elastic Container Registry): Deploying Kubernetes clusters to mirror container workloads from on-prem, ensuring consistency across environments.
  • Amazon MSK (Managed Streaming for Apache Kafka): Supporting real-time data replication from on-premises systems.
  • Amazon S3 & EBS: Providing scalable storage for persistent data and backups.
  • AWS Systems Manager: Simplifying infrastructure management, patching, and remote access control.
  • AWS KMS: Enabling centralized encryption key management for compliance and data security.
  • AWS CloudTrail, CloudWatch & SNS: Delivering real-time monitoring, logging, auditing, and alerting to ensure system reliability.

Security & Governance

Renova Cloud implemented strict role-based access controls via AWS IAM, enforced SSL/TLS encryption, and configured AWS KMS encryption for data at rest and in transit. CloudTrail auditing ensured comprehensive visibility into all administrative activities.

Testing, Validation & Handover

A comprehensive validation phase tested workload replication, failover readiness, and operational resiliency. Following successful verification, Renova Cloud delivered training sessions to the Cambodian credit guarantor’s IT team, enabling full self-management of the DR environment.

BENEFITS

Financial Benefits

  • Reduced Capital Expenditure: Avoided the high upfront cost of building physical DR infrastructure.
  • Optimized Ongoing Costs: Pay-as-you-go AWS pricing minimized operational expenditures while ensuring scalability.

Operational Benefits

  • Business Continuity: Rapid failover capabilities minimize potential downtime during disaster scenarios.
  • Scalability & Flexibility: Easily adapt to changing business demands with elastic cloud resources.
  • Simplified Management: Automation tools reduce manual workload, allowing the IT team to focus on higher-value initiatives.

Performance Improvements

  • High Availability: Kubernetes clusters and critical workloads can scale dynamically as needed.
  • Faster Recovery Times: Reduced Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) compared to traditional DR.
  • Enhanced Resilience: AWS-managed services ensure system uptime, data integrity, and consistent performance.

CONCLUSION

Through close collaboration with Renova Cloud, the Cambodian credit guarantor successfully modernized its disaster recovery strategy by leveraging AWS’s highly available, secure, and scalable cloud platform. This project not only safeguards the company’s mission-critical systems but also establishes a strong technical foundation for future cloud-native initiatives, supporting the organization’s long-term growth and digital transformation journey.
