Challenge
International e-commerce company processed telemarketing orders through a backoffice system written in Visual Basic. The system ran on-premises, was hard to modify and could not keep up with growing demands of seven European markets. It needed a rewrite and a move to cloud without stopping operations.
Legacy system difficult to maintain and extend
Multiple markets, each with its own configuration and local adjustments
Cloud migration without disrupting operations
Order processing, inventory management, payment matching
Lower operating costs compared to on-premises
Long-term support and development after migration
Solution
We rewrote the system into C# .NET and deployed it to Azure. Each market has its own instance with local adjustments. Since migration we handle operations, monitoring and development.
