A US retail leader sought secure, high-performance solutions for transactions, inventory and supply chain. HCLTech was chosen to optimize IBM’s mainframe, ensuring business continuity and compliance.
The Challenge
Legacy infrastructure and mounting technical debt
The client faced multiple obstacles that impacted its ability to operate effectively. These included:
- Need for seamless infrastructure optimization without operational disruption
- Requirement for a technology partner to drive transformation and manage post-transition infrastructure
The Objective
Leveraging end-to-end mainframe as a service (MFaaS)
The client’s fundamental objective was to unify its mainframe operations to maximize its benefits and minimize potential vulnerabilities and risks. They wanted end-to-end support and managed services for the latest IBM hardware, software and related third-party software.
The Solution
Mainframe migration and upgradation
HCLTech migrated the client’s mainframe environment to a collocation data center to ensure dedicated space for client-exclusive operations. We also onboarded next-generation mainframe equipment to reduce the mounting technical debt. Our team optimized the storage environment and eliminated the “ghost clusters” interspersed across the client’s tape grid. Owing to our standardized global delivery model, the transition was completed on schedule and as per the initially defined targets. We ensured consistent service throughout the transition phase to keep operational disruptions at bay.
The Impact
Reduced TCO and optimized performance
The American retail service provider reaped both qualitative and quantitative benefits as a result of partnering with HCLTech for the mainframe transition and optimization, including but not limited to:
- Reduced mainframe TCO by 20%
- Refreshed and upgraded MFaaS model (z14 to z16)
- Minimized operation disruption owing to the zero-defect transition
- Prevented budget compromise by completing the project as per the SLA timeline
