Client Overview

A Distributed Telecom Enterprise at a Crossroads

A large Media & Telecom organization operating across distributed geographies.

Hybrid Exchange (on-prem + Office 365)

Legacy infrastructure with high operational overhead

Fragmented identity and access management

Increasing demand for high availability and seamless collaboration

Key Challenges

Cost, Complexity, and Continuity Pressures

Four critical pressure points blocking modernization at scale.

High Infrastructure Costs

  • Over-provisioned Azure workloads
  • Inefficient VM utilization
  • Lack of cost governance and tagging

Frequent Downtime & SLA Breaches
