Platform Infrastructure & Performance

Epic Overview

EPIC: Platform Infrastructure & Performance

DESCRIPTION: Design and implement a robust, scalable, and high-performance infrastructure for the REC Verifiable Credentialing Platform. The infrastructure will be cloud-hosted, support multi-tenancy, ensure high availability, implement disaster recovery mechanisms, and meet performance requirements for response times and concurrent users. The system will be designed to scale both horizontally and vertically as demand increases.

BUSINESS VALUE: Provides a reliable, responsive, and resilient foundation for the platform, ensuring consistent service delivery even during peak usage. The scalable architecture allows the platform to grow with increasing adoption, while the high availability and disaster recovery capabilities minimize downtime and data loss risks, protecting both business continuity and reputation.

STAKEHOLDERS: - REC (Platform Owner) - Staffing Companies - Candidates - Velocity Career Labs (VCL) - Operations and Support Teams

SIZE: Large - Infrastructure is a critical component that requires significant planning and implementation effort.

USER STORIES: - As a platform administrator, I want the solution to be cloud-hosted so that we can leverage cloud scalability and reliability. - As a platform administrator, I want the system to be scalable both horizontally and vertically so that it can handle increasing demand. - As a platform administrator, I want to support a multi-tenanted environment so that we can serve hundreds of staffing companies. - As a platform administrator, I want to ensure 99.9% uptime with self-healing capabilities so that the service remains available to users. - As a platform administrator, I want to implement disaster recovery plans so that the system can be fully restored within 24 hours if needed. - As a platform administrator, I want to implement regular data backups so that data can be retrieved for the last 30 days. - As a staffing company user, I want the user interfaces to be mobile-responsive so that I can access the platform from any device. - As a staffing company user, I want the system to handle high transaction volumes so that operations aren't delayed during peak times. - As a staffing company user, I want response times under 2 seconds for all major actions so that I can work efficiently. - As a candidate, I want the platform to be responsive and reliable so that I can easily manage my credentials.
