How GeoPITS Helped IIHT Modernize Its E-Learning Platform by Migrating from Monolithic Architecture to Microservices
Seamless SQL Server to PostgreSQL migration for 456 clients with secure, scalable, and isolated data environments.
Overview
The Challenge
The system was also implemented as a 'macro' or shared-database architecture, which led to problems in performance and scalability.
Migrated 456 clients to separate PostgreSQL databases without disrupting e-learning access.
Required a reliable, secure migration process with minimal downtime.
The system needed to handle large volumes of data transfer efficiently with validation and error control.
Our Solution
Designed dedicated PostgreSQL databases for each of IIHT's 456 clients.
Migrated all client data from SQL Server to PostgreSQL by utilizing optimized Azure Data Factory pipelines.
Built robust validation and error-handling flows to maintain data accuracy.
Tuned PostgreSQL configurations for performance and security across all client databases.
Migrated in a phased manner with minimum downtime and smooth cutover.
Benefits
Business Impact
Improved Scalability
Each client now has an isolated PostgreSQL database, and scaling and maintenance of the system are therefore easier.
Enhanced Efficiency
Microservices architecture lessened the load on the platform, therefore providing faster access and smoother course operations.
Improved Security
Data isolation strengthened compliance, privacy, and overall security for all 456 clients.
Reliable Migration Process
ADF pipelines enabled accurate, phased, and disruption-free migration across all client environments.
