Tata Consultancy Services Success Story

Tata Consultancy Services (TCS) was engaged by a leading life and pensions company, headquartered in London, to build out a new data center. The client's existing data center incorporated a diverse range of technologies and systems, resulting in a complex network that demanded intensive management and extraordinary amounts of time to bring a new service to market while increasing operation costs. Infrastructure age and complexity also restricted the company’s ability to scale to meet growing business requirements. More than 8,000 users needed access to enterprise applications and resources that resided on mainframes and servers, and storage demands were steadily increasing. The data center network also had to support quality of service for voice traffic. The new data center had to be able to support multitenancy and enable a path to SDN. At the same time, TCS needed to migrate all applications and millions of policies to the new data center with no changes to IP addressing of the application systems.

The client is a leading life and pensions company, headquartered in London, and offers a range of retirement and pension services to more than five million customers. To maintain its lead in a highly competitive market, the client had launched a service improvement program to accelerate time to market for new services, improve delivery efficiency, and remain flexible as new market opportunities arise. Its existing data center incorporated a diverse range of technologies and systems. The Cisco data network had evolved over many years, resulting in fragmented VLAN Trunk Protocol (VTP) domain networks with multiple core switches and a mix of two-tier and flat network architectures. Point-to-point WAN links connected three data centers and 11 office locations, which altogether used more than 1,100 network devices from various vendors.
