Tata Consultancy Services

Tata Consultancy Services (TCS), India's largest IT services company, generated approximately $22.2 billion in revenue in FY2021 (₹164,177 crore) with a workforce of 488,649 employees. While TCS had a well-established global delivery model and the Tata brand, the rapid shift in enterprise IT spending toward cloud transformation created both an opportunity and a challenge. Hyperscaler platforms — AWS, Microsoft Azure, and Google Cloud — were becoming the default infrastructure for enterprise IT, and clients increasingly required partners with deep, certified expertise on these platforms rather than generic IT outsourcing capabilities. TCS needed to rapidly build credible hyperscaler practices at scale to capture this demand wave, which required training tens of thousands of consultants, developing platform-specific solutions, and establishing co-go-to-market relationships with the hyperscalers themselves.

Between FY2021 and FY2024, TCS invested in building dedicated hyperscaler practice units and deepening strategic partnerships with all three major cloud providers:

• Microsoft partnership at scale: TCS built a dedicated Microsoft Business Unit with over 50,000 trained professionals delivering industry-focused solutions on Microsoft's cloud platform. By 2022, TCS achieved 17 Microsoft Advanced Specializations — a record number — including AI and Machine Learning on Azure, Analytics on Azure, and Data Warehouse Migration to Azure. TCS completed more than 1,000 Azure engagements for hundreds of global customers. This earned TCS the 2022 Microsoft Partner of the Year in five categories (Global SI & Advisory Digital Transformation, Retail & Consumer Goods, SAP on Azure, US Advisory Services, US Financial Services), plus recognition in nine additional global categories. TCS followed this with five 2023 Microsoft Partner of the Year Awards.

• AWS Premier Partnership: TCS maintained AWS Premier Consulting Partner status — the highest tier — with over a decade of collaboration. The partnership culminated in TCS winning the AWS Global System Integrator (GSI) Partner of the Year — Global award at AWS re:Invent 2023. In April 2024, TCS and AWS signed a multi-year strategic transformation agreement under which AWS committed to upskill 25,000 TCS professionals on cloud and generative AI capabilities, enabling TCS to deliver full-stack digital transformation including cloud modernization, data platforms, and GenAI solutions.
