Transforming H&M’s
Data Architecture Through Migration

H&M, a global retail leader, faced scalability, query speed, and manual workflow challenges with its Azure-based data infrastructure. To enhance efficiency and enable data-driven decisions, H&M migrated to the Google Cloud Platform (GCP) for its high-performance analytics, streamlined operations, and scalable cost-effectiveness.

Challenges

  • Struggled with the rapid growth of data volumes-the tools that were used initially could not handle the volumes, meaning that query response times slowed down.
  • Inefficient workflows-manual interfaces introduced inefficiencies, brought in the possibility of errors due to manual intervention in each step of the data lifecycle.
  • Scalability issues infrastructure was not scalable in regard to H&M’s new business requirements.
  • Operational bottlenecks-the workflows presented were complex, and the level of automation was low, creating huge roadblocks to overall operational efficiencies.
  • Diverted Focus from Analytics: The requirement of human intervention in workflows resulted in the diversion of focus away from analytics and actionable insights.

Solution

We moved to Google Cloud Platform and further optimized BigQuery to be efficient and scalable. We leveraged DBT to make data transformation automated, minimize errors, and standardize processes.

We built effective end-to-end data pipelines that included proactive monitoring using Cloud Composer orchestration. Additionally, we equipped the teams of H&M through training and workshops in GCP, BigQuery, and DBT, making the operation independent and scalable.
