Cloud Storage Implementation for a .NET Application in the Education Sector

Case Study Overview

Our client, an established education provider, sought a cloud storage solution for their .NET application to manage vast, complex data types—both structured and unstructured. Needing a solution that supported robust analytical and dashboard capabilities, we implemented a hybrid storage architecture combining a data lake for unstructured, NoSQL data storage and a data warehouse for structured data, optimized for report generation. Given .NET’s close integration with Microsoft technologies, Azure was selected as the primary cloud provider due to its compatibility and superior support for .NET applications compared to AWS. For structured data, Azure SQL Server provided a reliable, high-performance database solution with integration options across multiple data sources.

Utilizing AWS S3 buckets optimized file handling, resulting in a 70% improvement in data retrieval performance. The database setup included clustered storage with no redundancy for secure, high-speed data access.

The customer was also struggling to manage and report on their massive on-premises data across multiple locations. To address this challenge, we migrated their data to the cloud using RubiCube, a user-friendly platform that consolidates data from various locations into a single, easily accessible view.

With RubiCube, we enabled a seamless cloud-based analytical solution, allowing consolidated visibility across locations, reducing maintenance costs by up to 40%, and offering pay-as-you-go flexibility. CIG provided continuous maintenance and team training to support the client in their digital transformation, creating a scalable and efficient foundation for future growth.

Client Background

Our client, a leading education provider, faced significant challenges managing and accessing data spread across multiple on-premises systems. These systems stored a mixture of structured and unstructured data related to student information, attendance records, academic progress, and administrative documents, creating inefficiencies in data handling, analysis, and report generation. Their existing solution was a desktop application developed in VB, limiting scalability, ease of updates, and integration options with other applications. With plans to transition to a more efficient, cloud-based .NET Core application, the client sought a comprehensive solution to streamline data storage, improve performance, and reduce costs.

Challenges

The legacy desktop application was becoming increasingly difficult to maintain due to the frequent functional updates required to support the growing chain. This led to performance degradation and operational challenges. By migrating the application to the cloud, we can ensure consistent performance, centralized control, and efficient updates, eliminating the need for tedious manual or automated updates across numerous desktop installations.

• Data Complexity: The client handled both structured and unstructured data, requiring a storage solution that could support this diversity.
• Data Accessibility & Report Creation: Consolidating data across multiple locations into a single source of truth was crucial to generating real-time reports, particularly for analytics and AI/ML applications.
• Scalability Limitations: Maintaining data on-premises limited the scalability, flexibility, and integration of the application with new and evolving educational tools and technologies.
• Maintenance Overhead: Updates and feature additions to the VB desktop application were time-consuming and required frequent, manual deployments across multiple systems.
• Cost Implications: The on-premises setup incurred high maintenance and operational costs, making it difficult to sustain their growing data needs.

Leverage cloud storage solutions for businesses to securely store and access critical data from anywhere, enhancing collaboration and productivity.
