Case Study - Transforming Database Resilience for Diglossia with Amazon RDS for PostgreSQL |
Diglossia, an EdTech startup, is dedicated to transforming the education landscape in the Middle East. The company focuses on empowering underprivileged children by providing educators and government agencies with insightful tools to assess Arabic language literacy levels. Diglossia's automated tests, incorporating written, spoken, and visual methodologies, enable educators to gain a comprehensive understanding of literacy levels at a population scale. This information helps formulate effective policies and strategies to enhance lives and build a brighter future for the region's youth. |
Diglossia faced a critical challenge with its on-premise hosting solution managed by a third-party provider. During testing seasons, where hundreds of thousands of students took exams on the platform, the database experienced unpredictable and massive loads. The peak hours witnessed millions of transactions, making it nearly impossible to manage the database load effectively. This led to frequent instances of downtime throughout the month, causing significant concerns about business losses. Given the central role of the database in Diglossia's application, addressing this challenge was of utmost importance. |
In response to Diglossia's challenge, our team proposed and executed a migration to Amazon Web Services (AWS), specifically leveraging Amazon RDS for PostgreSQL with Multi-AZ (Availability Zones), a choice guided by several key differentiators that addressed the limitations of traditional on-premise hosting and offered a transformative solution:
|
The implementation of Amazon RDS for PostgreSQL brought about a transformative change for Diglossia. The shift from multiple downtimes during peak periods to virtually no downtime has significantly enhanced the reliability and performance of their education platform. The adaptability of read replicas to handle varying workloads during testing seasons has ensured a seamless experience for students and schools. With automated backups and PITR, Diglossia has achieved data resilience and recovery capabilities, further safeguarding their valuable educational resources. |
