HCLTech partnered with a leading Swedish retailer to migrate its on-prem Optiva Infor PLM system to AWS, addressing issues of limited scalability, complex maintenance and low resiliency. By leveraging AWS's scalability, security and geographic resilience, HCLTech implemented a robust cloud architecture with Infrastructure as Code (IaC) and disaster recovery strategies. This migration enabled rapid provisioning, enhanced uptime, on-demand scalability and cost optimization, significantly boosting the client’s operational efficiency and resilience.
The Challenge
The client relied on an on-prem Optiva Infor PLM system to manage the lifecycle of its food products. However, this setup posed several challenges:
- Limited scalability and upgrade capabilities
- Complicated maintenance of infrastructure
- Lack of resiliency in the PLM application
The Objective
The client aimed to migrate their Optiva Infor system from on-prem SaaS to AWS, addressing the limitations of the existing setup and improving overall efficiency, security and resilience. The key objectives were:
- Improve scalability and operation model, upgrade ease and simplify infrastructure maintenance
- Leverage cloud benefits of high availability, geographic resiliency and security
- Implement Infrastructure as Code (IaC)
These drivers focused on modernizing the client's infrastructure, increasing efficiency and ensuring robust security and resiliency.
The Solution
HCLTech led a comprehensive transformation of the client's PLM system to AWS, ensuring resilience and disaster recovery capabilities. Key components of the solution included:
- Cloud transformation: HCLTech migrated the client's on-prem hosted PLM to AWS, addressing the business challenges. The transformation leveraged Infrastructure as Code (IaC) to automate infrastructure creation.
- Geographically resilient architecture: HCLTech designed a geographically resilient deployment architecture, increasing application availability even in the event of a disaster.
- Disaster recovery strategy: A backup and restore strategy was implemented using AWS Backup to meet the client’s recovery point objective (RPO).
- Disaster recovery drill: A disaster recovery (DR) drill was conducted to validate the ability to restore the application within the defined recovery time objective (RTO).
- Detailed DR guide: A comprehensive disaster recovery guide was developed, detailing pre-requisites, DR drill activities and post-drill rollback steps.
This approach improved system reliability and ensured quick recovery in case of disruptions.
The Impact
The migration to AWS delivered transformative benefits, including faster infrastructure provisioning, increased uptime, on-demand scalability and optimized costs through AWS’s flexible pay-as-you-go model.
- Accelerated infrastructure provisioning: Reduced infrastructure provisioning from months to hours using automated deployment
- Increased availability: Geographically resilient architecture improved uptime, even during disasters.
- On-demand scalability: Resources could be resized in minutes to meet changing demands. System upgrades were faster as the wait times for new infrastructure were removed.
- Optimized costs: The pay-as-you-go model provided cost efficiencies, enabling the client to optimize expenses based on usage.
