About the Client

The customer is a leading private-sector bank in India that runs mission-critical banking applications on AWS across multiple regions. These workloads support core banking platforms, digital channels, and internal enterprise systems.

Business Challenge

The bank had adopted AWS early, but its infrastructure was provisioned and managed manually across regions. As regulatory expectations increased, this operating model created multiple challenges:

• Manual deployments leading to operational overhead and inconsistencies.
• Longer provisioning and change cycles, impacting time-to-market.
• Limited traceability and repeatability for audits.
• Increased pressure to comply with RBI and regulatory mandates.
• Need for a controlled, standardized, and automation-driven operating model.

As an existing AWS Managed Services customer, the bank approached us to modernize its infrastructure operations while continuing under a managed services engagement.

Business Solution

As the bank’s trusted managed services partner, NuSummit expanded its scope to include Infrastructure-as-Code (IaC)– driven operations while retaining full ownership of day-to-day AWS management.

Key managed services delivered:

• IaC Enablement as Part of Operations: Converted manually-deployed AWS infrastructure into Terraform-based Infrastructure as Code, ensuring parity and stability.
• Automated and Controlled Deployments: Integrated Terraform with CI/CD pipelines and Git-based version control to enforce approval-driven, auditable changes.
• IaC-Driven Day-2 Operations: All infrastructure provisioning, changes, and updates executed exclusively through code by our managed services team.
• Governance, Security, and Compliance: Improved audit readiness through traceable change history, standardized configurations, and consistent controls across regions.
• 24×7 Managed Support: Continuous monitoring, incident management, and operational oversight of AWS environments.

Business Impact

With NuSummit’s IaC-enabled AWS Managed Services, the bank achieved:

• Improved audit and regulatory compliance with fully traceable, code-driven infrastructure.
• Faster deployments through automated, repeatable pipelines.
• Reduced operational Risk by eliminating manual changes and configuration drift.
• Higher operational efficiency with lower deployment effort and faster issue resolution.
• Improved time-to-market for banking applications and regional expansions.

Outcome

By extending its partnership with NuSummit, the bank transformed AWS operations from a manual, effort-intensive model to a fully automated, IaC-driven managed platform.

Today, all AWS infrastructure is deployed and managed through Terraform and CI/CD pipelines, under the continuous supervision of our 24×7 AWS Managed Services team, ensuring compliance, agility, and operational excellence at scale.
