Greenfield Telecom Service Switching Platform Revolutionizing Service Migration with Cloud-Native Agility

Client

A Leading telecom provider, needed a robust and future-ready system to enable seamless transitions between broadband and landline service providers without disrupting customers or operations. 

This was a greenfield initiative: no legacy to refactor, but also no system to build upon. Speed, security, and scalability were non-negotiable. 

That’s where TechTez stepped in.

The Challenge

In the dynamic telecom landscape, portability and provider-switching workflows are often slowed by rigid systems and manual handovers.

  • A self-healing, resilient backend
  • Secure and frictionless data workflows
  • Modular components for future adaptability
  • A reliable AWS-native foundation

Our Strategy:

We architected and delivered an end-to-end cloud-native solution using AWS services, modern DevOps, and microservices principles. The system now handles:
  • Service Switching at Scale : Across regions and providers
  • Seamless API Integration : With DNS routing, email, and SMS workflows
  • Event-Driven Processing : Leveraging Fargate and Lambda
  • Workflow Orchestration : Using Camunda BPM for business logic

Tech Stack:

  • Built for Scale & Resilience : Using Amazon ECS + Fargate across 3 availability zones, we ensured zero-downtime deployments with auto-scaling built in.
  • Secure by Design: AWS Shield, WAF, and parameter store manage access, policies, and secrets across services.
  • Intelligent Workflow Management: Camunda BPM powers decision logic and stateful transitions for each switching request.
  • Smart Data Layer: The system leverages DynamoDB for performance and Aurora Serverless for critical persistence ensuring both speed and durability.
  • Async Processing at Its Best: Apache Artemis + EFS enable durable queue management and high-throughput message delivery between distributed components.
  • Communication Made Seamless: AWS SES/SNS allow for real-time status alerts and automated transactional messaging to users and administrators.

Impact & Results:

  • Delivered a fully containerized platform using AWS CDK
  • Reduced switching request latency by over 60%
  • Achieved near zero downtime during peak test simulation

We didn’t just build for specs we built for intent. 

With TechTez, every architecture is modular, every decision data-backed, and every sprint driven by impact, not just output.
