A Major Player In The Telecom Software Industry

A major player in the telecom software industry set out to modernize its infrastructure to support a fully digital mobile and internet service model. Designed around next-generation customer expectations, the platform enables all customer transactions to be handled digitally—without the need for a call center, physical store, or manual intervention. The primary goal of the modernization initiative was to minimize potential service interruptions while ensuring consistent performance, system resilience, and intelligent traffic routing. To support this transformation, the company partnered with Sufle to migrate and modernize its infrastructure on Amazon Web Services (AWS), leveraging the cloud’s security, scalability, and cost-optimization benefits.

Operational Improvements

Prior to the migration, the company’s legacy infrastructure faced several challenges. Manual deployments were frequent and time-consuming, monitoring was fragmented, and scaling was difficult to manage during peak usage periods. As the service expanded to support multiple brands and customer channels, the limitations of the system became more apparent. The modernization effort aimed to resolve these bottlenecks by introducing automation, dynamic resource scaling, centralized monitoring, and intelligent traffic routing. The end goal was to deliver a future-proof platform capable of supporting growth, reducing operational complexity, and improving service quality across the board.

Why Sufle?

The organization chose Sufle for its strong expertise in cloud migration, automation, and Kubernetes-based architectures. 

Sufle’s proficiency in Infrastructure as Code (IaC), GitOps workflows, and container orchestration played a key role in establishing a scalable and secure foundation. The new architecture was designed to support rapid expansion, including the ability to replicate infrastructure for new regions or brands, with minimal rework.

Migration and Modernization on AWS

The entire infrastructure including operational workloads, observability stack, CI/CD tooling, and application environments—was migrated from legacy on-premises and cloud platforms to AWS.

A containerized architecture was implemented using Amazon EKS (Elastic Kubernetes Service), allowing microservices to scale independently. All infrastructure components were defined using IaC with Terraform, enabling consistent deployment across isolated environments. CI/CD pipelines were built from scratch using Bitbucket, Jenkins, and ArgoCD, ensuring seamless and automated application delivery across test, staging, and production.

Isolated Environments and High Scalability

To support modular growth and improve security, the new architecture provided fully isolated environments for each brand and workload. These environments were built to handle high traffic and were configured for elasticity using Amazon EC2 Auto Scaling and Karpenter. By dynamically provisioning infrastructure based on actual usage, the system maintained high performance even during peak traffic periods while optimizing infrastructure costs. This dynamic scaling capability now allows the platform to scale horizontally with demand, without the need for manual intervention or overprovisioning.

A Fully Secured Environment

Security was embedded in every layer of the modernization effort. The environment was protected using a combination of AWS GuardDuty and VPC Flow Logs, which provided continuous threat detection and traffic auditing. Real-time monitoring and security audits were enabled through Amazon CloudWatch and AWS CloudTrail, ensuring that infrastructure performance and access events could be tracked and verified at all times. Secrets management was handled through AWS Secrets Manager, and encryption was enforced for all data at rest and in transit using AWS KMS and SSL/TLS protocols. IAM policies were configured to follow least-privilege access models, and all administrative access was protected with MFA.

Business Benefits

The migration to AWS delivered measurable business outcomes. With its new architecture, the company is now capable of supporting a 150% increase in traffic during high-activity periods without performance degradation.

Deployment times have been reduced from several minutes to under one minute, enabling rapid rollout of new features and hotfixes. The introduction of infrastructure as code (IaC) and GitOps has significantly reduced operational complexity, allowing infrastructure teams to focus on innovation instead of maintenance.

The architecture now supports independent deployment and operation of each digital brand within the platform, offering enhanced scalability, reduced downtime, and strong security governance across all layers.
