Client Overview

A mid-sized financial enterprise with a global presence faced challenges with outdated on-premises IT infrastructure. The company sought a scalable and cost-effective cloud solution to enhance performance, reduce costs, and support business growth.

Challenges

Legacy Infrastructure: Frequent downtime and inefficiencies due to outdated hardware and software.
High Operational Costs: Significant expenses associated with maintaining on-prem servers, storage, and networking.
Scalability Constraints: Inability to dynamically scale resources to meet fluctuating business demands.
Security & Compliance Requirements: The need for improved security measures and adherence to financial industry regulations.
Remote Workforce Enablement: Ensuring secure access for remote employees and global teams

Technology Used

Nexus Infra 360 partners with industry-leading OEMs to deliver top-tier infrastructure solutions.

Solution

AWS Cloud Migration

To address these challenges, a phased migration strategy was implemented to ensure minimal disruption and seamless transition.

1. Assessment & Planning

Conducted a comprehensive infrastructure audit to identify dependencies, workloads, and risks.
Developed a cloud migration roadmap, prioritizing mission-critical applications.
Chose AWS EC2 for compute, RDS for database management, S3 for scalable storage, and AWS Managed Microsoft AD for directory services.
Defined a hybrid migration approach to maintain operational continuity during transition.

2. Migration Execution

Hybrid Connectivity Setup: Configured a site-to-site VPN and AWS Direct Connect for secure, low-latency data transfer.
Workload Migration: Leveraged AWS Server Migration Service (SMS) for virtual machine migration and AWS Database Migration Service (DMS) for database replication.
Storage Transition: Moved legacy file storage to Amazon S3 with lifecycle policies for cost efficiency.
Security & Compliance Enhancements: Implemented AWS IAM for identity management, Security Hub for threat monitoring, CloudTrail for audit logging, and GuardDuty for anomaly detection.

3. Validation & Optimization

Conducted application performance testing, security validation, and load testing to ensure cloud infrastructure stability.
Fine-tuned AWS Auto Scaling policies to optimize performance and cost.
Decommissioned on-prem infrastructure following thorough post-migration verification.
Utilized AWS Cost Explorer and Trusted Advisor for continuous cost management and efficiency improvements.

Business Impact

50% cost reduction by eliminating on-premises infrastructure and optimizing cloud resources.
Enhanced scalability with auto-scaling AWS services, allowing seamless expansion and contraction of resources.
60% improvement in security posture with AWS-native security tools and compliance frameworks.
99.99% uptime achieved through a highly available, multi-AZ architecture.
Improved workforce productivity with secure, remote access to cloud-hosted applications and data.

Conclusions

By migrating to AWS, the enterprise achieved a secure, scalable, and cost-effective infrastructure with minimal downtime. The transition enhanced operational efficiency, security, and business agility, enabling future growth and innovation.
