Case Study: Vodafone Germany achieves secure, highly available OSS modernisation with TCS

Vodafone Germany modernizes 140+ servers with TCS and restores 5-minute polling

Vodafone Germany faced significant operational and security risks within its highly integrated OSS landscape. Its legacy monitoring ecosystem was unsupported, leading to stability issues, security vulnerabilities, and performance problems like polling delays of up to two hours. To address these challenges, Vodafone partnered with vendor Tata Consultancy Services (TCS) to modernize its network management systems.

TCS executed a comprehensive upgrade of the OSS stack, which included modernizing DX NetOps Spectrum, the operating system to RHEL, and the virtualization layer to VMware ESXi across more than 140 servers. The solution implemented by TCS restored full vendor support, eliminated recurring crashes, and improved polling intervals to five minutes. The results included enhanced security, a more stable infrastructure with 10-15 minute maintenance recovery, fewer false alarms, and the addition of five new landscapes to support future growth, all achieved with minimal service disruption.
