A US-based aviation services leader increased its business applications portfolio; they wanted to expand their Azure footprint. This growth created a need for stronger governance, security controls, and architectural consistency to support safety and scalability.

They sought to simplify their operations through automation, unify deployments, and improve visibility into security risks. They partnered with Nagarro to build a secure, governed cloud foundation, designed to ensure scalable operations, strengthen security, and support long-term growth.

The challenge

The client’s Azure environment had grown rapidly to support evolving business needs, but the absence of a secure, standardized cloud foundation created gaps in visibility, governance, and control. This made discovery, validation, planning and execution even more challenging. As workloads expanded, inconsistent architecture and manual practices increased security exposure, operational complexity, compliance risk, and resilience challenges.

Exposed infrastructure

They required stronger access and connectivity controls to support secure, scalable access to critical cloud services.

Lack of centralized governance

The organization needed consistent centralised governance, policy enforcement, and architecture standards while deploying resources to meet changing business demands. 

Inconsistent cloud foundation

They wanted to enhance their Azure landing zone with standardized networking, identity, connectivity, and security capabilities to support enterprise-scale operations.

Resilience & efficiency gaps

The client sought to establish a consistent disaster recovery framework and greater automation to improve resilience, efficiency, and cost predictability.

The solution

Nagarro strengthened security controls and redesigned the network architecture to align with enterprise cloud best practices. We enhanced and modernized the client's Azure landing zone, implementing zero-trust principles, centralized governance, and automation. This created a secure, compliant, consistent, and scalable Azure foundation that supports current workloads and future cloud growth.

The engagement focused on six pillars

results-icon

Secure Azure landing zone

We automated key processes and standardized management groups, hub and spoke connectivity and network segmentation. And centralised firewalling, private connectivity. In parallel, we implemented shared services for monitoring, backup, policy enforcement, and automation to improve security posture, governance, and operational consistency.

Zero Trust network architecture

We ensured network segmentation and secured traffic inspection across the Azure environment. And implemented secured ingress and egress pattern using centralized firewall controls, private endpoints, Web Application Firewall, restricted internet exposure, traffic inspection, and secure hybrid connectivity.

Identity and access control

We enforced role-based access control, privileged identity management, and least-privilege access. Additionally, we introduced Azure Virtual Desktop to provide secure access for development and administrative teams, reducing reliance on unmanaged endpoints.

Governance & policy enforcement

Azure Policy, automated monitoring, and centralized governance frameworks were introduced to prevent misconfigurations, maintain consistency, and enforce compliance across environments.

Automation and platform engineering

Nagarro implemented Infrastructure as Code, automated network provisioning templates, and CI/CD pipelines to standardize deployments, improve efficiency, and reduce operational overhead. A scalable Data Platform and Data Landing Zone also enabled secure data management, governance, analytics, and data-driven decisions.

The impact
