A global technology services leader partnered with HCLTech to transition from legacy systems to a secure, scalable AWS environment. This transformation addressed challenges like poor scalability, high operational costs and security risks while ensuring regulatory compliance and enabling more agile operations.
The Challenge
- Limited scalability: Legacy systems could not scale to meet demand, causing performance bottlenecks
- High costs: On-prem infrastructure incurred significant maintenance and energy costs
- Security and compliance risks: Outdated systems couldn't meet stringent security and compliance standards
- Operational inefficiency: Complex processes and manual management reduced agility and innovation
The Objective
The goal was to modernize infrastructure through AWS cloud solutions to reduce operational costs, improve scalability and meet regulatory compliance standards.
- System review: Comprehensive analysis of legacy systems and IT requirements identified key challenges and areas for improvement
- Cloud strategy: Developed a phased migration plan to ensure a smooth transition and reduce operational disruptions
The Solution
HCLTech's strategy focused on modernizing the client's IT landscape with AWS:
- Cloud migration: Migrated workloads to AWS, leveraging services like Amazon RDS and EC2 for better performance and scalability
- Cost optimization: Implemented a flexible AWS pricing model, including AWS Serverless and RDS, to reduce infrastructure costs
- Security and compliance: Utilized AWS's built-in security features like IAM, encryption and VPC for enhanced compliance
- Automation: Leveraged AWS CloudFormation to automate resource provisioning and monitoring, increasing operational efficiency
The Impact
- Cost savings: Reduced operational costs by 30-50% through AWS's pay-as-you-go pricing and optimized database solutions
- Scalability: Achieved 50% faster transaction processing and the ability to scale seamlessly with AWS EC2 and Fargate
- Operational efficiency: Streamlined operations with automated scaling, monitoring and analytics, improving overall productivity by 30-70%
- Regulatory compliance: Ensured full compliance with industry regulations through AWS's security features and certifications
AWS services used:
Amazon EC2, Amazon RDS, AWS Lambda, AWS CloudFormation, Amazon S3, AWS IAM
