Project Overview
Our client, a US based prominent EMR (Electronic Medical Records) software solution provider, offers a single-tenant application utilised by multiple hospitals and clinics. This critical application, powered by Progress OpenEdge, was hosted on 400 EC2 instances running outdated operating system versions. To enhance security, performance, and scalability, the client sought to migrate their application to newer EC2 instances with updated OS versions and Progress OpenEdge.
Challenges
Following challenges were identified while the scoping discussions with the client:
- Scale and Complexity: Managing upgrades for 400 EC2 instances simultaneously posed a significant challenges across coordination, resource allocation, and risk management.
- Downtime Minimization: Minimizing downtime during the upgrade process was crucial to ensure uninterrupted business operations and avoid revenue loss.
- Automation and Coordination: Coordinating tasks across hundreds of machines required efficient automation and orchestration tools to streamline the process and minimize human error.
- Data Security and Compliance: As the application handles sensitive patient data, maintaining data security and compliance with healthcare regulations (e.g., HIPAA) throughout the migration process was critical.
- Quality Assurance: Rigorous testing and validation were essential to verify the functionality, performance, and compatibility of the migrated application with the updated infrastructure.
Solution
EbizOn devised a comprehensive solution leveraging industry best practices and cutting-edge technologies:
- Planning and Preparation: Meticulous planning, conducting thorough assessments of the existing infrastructure, application dependencies, and compatibility requirements. Created a detailed roadmap with tasks and timelines for the upgrade process.
- Technology Stack: We opted for terraform to provision new EC2 instance. Airflow, an open-source workflow management platform, was deployed for task orchestration, providing a centralized platform for scheduling and monitoring upgrade tasks. Additionally, Ansible playbooks were utilized for executing OS updates, Progress OpenEdge version upgrades, and application validations.
- Automation and Orchestration: We developed custom Ansible playbooks to automat tasks such as creating snapshots, provisioning new instances, executing upgrade scripts, and performing post-upgrade validations. Airflow DAGs (Directed Acyclic Graphs) were configured to schedule and sequence tasks across the entire fleet of EC2 instances, ensuring smooth coordination and execution.
- Testing and Validation to ensure infrastructure reliability: This included regression testing to verify application functi onality, performance testing to assess system performance, and security scans to identify and remediate vulnerabilities.
Impact
- Enhanced Security and Compliance by migrating to newer EC2 instances with updated operating system versions and Progress OpenEdge
- Improved Performance and Scalability due to upgraded infrastructure
- Future Readiness through modernized infrastructure
We turn your goals into reality.
