Development of a Cloud-Native Platform Support and Modernization Solution for Legacy Telecom Infrastructure

The client faces significant challenges in maintaining and modernizing mission-critical legacy systems that support customer services operating 24/7, with an infrastructure over three decades old, including numerous interconnected databases and billing systems. Transitioning to cloud-native architectures while ensuring zero downtime and operational continuity is complex, particularly when current development practices are waterfall-based. They need to adopt modern, scalable, and resilient infrastructure to compete with new media and digital disruptive startups, requiring deep ecosystem understanding and innovative integration of new and existing systems.

A large, established telecommunications provider with a legacy infrastructure of over 30 years, seeking to modernize their technology stack, adopt cloud-native platforms, and shift to an agile, DevOps-driven software development culture.

• Provide continuous, 24/7 support and maintenance for cloud-native platforms to ensure operational resilience and availability.
• Build and manage an efficient cache layer on top of legacy software systems to facilitate development of new features without impacting mission-critical operations.
• Upskill internal teams in cloud infrastructure management, platform operation, cloud-native application development, and DevOps practices.
• Enable rapid development and deployment of hundreds of microservices and applications, with over 500 applications in production, and more than 1000 in testing environments.
• Transition organizational practices from traditional waterfall methodologies to agile and DevOps cultures, emphasizing pair programming and continuous delivery.
• Establish resilient test and production environments to allow innovation without risking downtimes or system failures.
• Implement scalable, secure, and high-performance infrastructure supporting future growth and digital services.
