Techacademy is a well-known e-learning and IT training provider managing hundreds of client organizations on its learning platform. Techacademy partnered with Geopits to move from a shared-database, monolithic architecture to a microservices based model, migrating 456 clients from SQL Server to isolated PostgreSQL databases.

Business Challenges

As the Techacademy platform expanded, its shared database, or "macro" architecture began to impact performance and scalability. The company needs to migrate 456 clients to separate PostgreSQL databases without disrupting e-learning access, using a reliable and secure process with minimal downtime, while handling large volumes of data transfer with strong validation and error control.

Shared "macro" architecture

The platform's shared database architecture became a bottleneck as the client base grew, limiting performance, scalability, and operational efficiency.

Large-scale client separation

456 clients need to migrate to separate PostgreSQL databases without disrupting e-learning access.

Migration reliability

The migration required a reliable and secure process with minimal downtime across every environment.

Data volume and validation

large volumes of data need to be transferred efficiently, with strong validation and error control throughout.

Project Objectives

Geopits partnered with Techacademy to rebuild its data architecture around isolated, scalable databases without interrupting learners' mid-course.

Key Goals:

Move 456 clients to dedicated, isolated PostgreSQL databases

Migrate from SQL Server to PostgreSQL with minimal downtime

Strengthen scalability, security, and platform performance.

Solution Provided by Geopits

Geopits designed dedicated PostgreSQL databases for each of 456 clients and migrated all client data from SQL Server to PostgreSQL using optimized Azure Data Factory pipelines.

Dedicated client databases

A separate, isolated PostgreSQL database was designed for each of Techacademy 's 456 clients.

Automated migration pipelines

All client data was migrated from SQL Server to PostgreSQL using optimized Azure Data Factory pipelines.

Validation and error handling

The team-built validation and error-handling flows to maintain data accuracy throughout the migration.

Performance, security, and phased rollout

PostgreSQL configurations were tuned for performance and security, and the migration ran in a phased manner to ensure minimal downtime and a smooth cutover.

Results & Business Impact

Moving to isolated PostgreSQL databases and a microservices model improved performance, security, and long-term scalability.

Capabilities

Before

After

Database model

Shared, monolithic database

Isolated PostgreSQL database per client

Scalability

Difficult to scale as clients grew

Each client scales independently

Platform performance

Slower under shared load

Faster access, smoother course operations

Security and compliance

Shared-environment risk

Data isolation strengthens compliance and privacy

Migration process

Not applicable

Phased, validated, minimal downtime

Key outcomes

Improved Scalability

Each client now runs an isolated PostgreSQL database, simplifying scaling, maintenance, and independent resource management.

Enhanced Efficiency

The microservices architecture reduced platform load, enabling faster access, improved performance, and smoother course operations.

Improved Security

Data isolation strengthened compliance, privacy, and tenant-level security across all 456 client environments.

Reliable, Disruption-Free Migration

Azure Data Factory pipelines enabled accurate, phased migration across all client environments with no interruption to service, ensuring data integrity and business continuity.

Conclusion

Geopits partnered with Techacademy to modernize its e-learning platform by migrating from a monolithic, shared-database architecture to a microservices-based environment. Using a phased migration approach, Geopits successfully transitioned 456 client environments to isolated PostgreSQL databases with minimal downtime, improving scalability, security, and overall platform performance.
