Zero Data Loss Across 78+ Projects EKS Migration

A leading payments and business technology provider needed to transition from on-premises infrastructure to a cloud native architecture built on Amazon EKS. Aziro executed a phased migration across 78+ projects, standardized IAM and RBAC governance aligned with Active Directory, automated cluster provisioning and workload deployment, and delivered training to over 500 users. The result was a scalable, secure, highly available platform achieved with zero data loss and zero major downtime.

The organization's on-premises infrastructure constrained scalability, high availability, and centralized governance across multiple business units. Access management lacked standardization, and operational overhead from manual infrastructure processes slowed collaboration, security, and CI/CD performance across the environment.

• Fragmented Access Control: Access and cluster management lacked centralized governance, with no IAM-integrated RBAC policies aligned to Active Directory, complicating identity and permission management.

• Limited Scalability and Availability: On-premises infrastructure could not scale efficiently or ensure high availability across multiple business units, restricting growth and consistent service delivery.

• Operational And Infrastructure Overhead: Managing infrastructure without container orchestration or managed services increased operational burden, slowing CI/CD performance, and raising overall infrastructure costs.

Aziro designed and executed a phased migration strategy to move applications and repositories onto an EKS-based architecture. The approach combines automation, standardized governance, and careful sequencing to preserve data integrity and minimize disruption across 78+ active projects.

• Phased Project Migration: Applications and repositories were migrated to AWS EKS-based architecture across 78+ projects in structured phases, ensuring data integrity throughout the transition.

• Automated Provisioning Scripts: Python and AWS SDK based automation scripts were built for cluster provisioning, user access control, and workload deployment, reducing manual effort.

• Standardized IAM Governance: A 3-tier RBAC access model was established for developers, admins, and leads, streamlining governance and aligning access with Active Directory policies.

• Bitbucket (Server & Cloud), Git
• AWS EKS, EC2, S3
• Python, Shell, AWS SDK (Boto3)
• Atlassian Access, Azure AD, AWS IAM
• Bitbucket Pipelines, Jenkins, Ansible, AWS CodePipeline
• AWS CloudWatch, Prometheus, Grafana

The migration delivered measurable improvements across cost, governance, and reliability. Standardized access controls and automation reduced operational overhead, while optimized cloud usage and structured training ensured the organization was fully equipped to operate confidently in its new EKS environment.

• Zero Data Loss Migration: Executed seamless, end-to-end migration to AWS EKS with zero data loss, preserving full data integrity across all 78+ migrated projects.

• 500+ Users Trained: Conducted training sessions and created Confluence based documentation, onboarding over 500 users to AWS and EKS workflows successfully.

• 25-30 Workloads Archived: Optimized cloud footprint by archiving inactive workloads, reducing unnecessary resource consumption and eliminating unneeded licensing costs.

• Zero Major Downtime Achieved: Blue-green deployments, rolling updates, and controlled release strategies ensured zero major downtime throughout the entire migration process.

Aziro specializes in large-scale infrastructure migrations, helping enterprises transition confidently from on-premises systems to cloud native architectures on AWS. Our teams design phased migration strategies that preserve data integrity, minimize downtime, and maintain business continuity even across complex, multi-project environments. From automation scripting to standardized IAM governance, we build the frameworks organizations need to operate securely and efficiently at scale.

Beyond migration, Aziro supports long-term operational success through structured training, documentation, and cost optimization. We help teams adopt new workflows with confidence, reduce unnecessary cloud spending, and establish governance models that scale with business growth. Whether modernizing DevOps pipelines or re-architecting access management, Aziro partners with organizations to deliver measurable, lasting outcomes.
