Problem: Maraya, the official media platform of the Sharjah Broadcasting Authority (UAE), needed a high-availability solution to ensure business continuity. The challenge was to implement an affordable system capable of near real-time data replication with minimal downtime and data loss, especially during unexpected outages. ITWORKS ME's unique approach and expertise were crucial in addressing this challenge.
Solution: ITWORKS ME implemented Microsoft Hyper-V's live replication feature, achieving a 30-second replication delay. Additionally, a floating IP address configuration was integrated with Hyper-V Replica to enhance the flexibility and availability of virtual machines (VM) during failover scenarios.
Key Results: The solution provided near-zero downtime, ensured data integrity, and allowed for seamless failover using floating IP addresses. Notably, achieving a 30-second live replication delay was a significant milestone, enhancing the reliability and resilience of Maraya’s IT infrastructure.
