Migrating Finance Applications to AWS Cloud for 30% Cost Reduction

Client Problem

A leading financial services company faced critical challenges with their outdated on-premise infrastructure that was unable to meet increasing demands. The legacy systems led to frequent downtime and limited scalability, hindering their ability to innovate and adapt to market changes swiftly.

The rigid infrastructure made it difficult to respond to changing business needs, while manual infrastructure management processes were time-consuming and error-prone. Additionally, the complexity of meeting compliance and security requirements in the financial services sector created significant barriers to modernization.

Solution: Migration to AWS Cloud

Tasrie IT Services’ decision to migrate the client’s finance applications to the AWS cloud was driven by the need to enhance scalability, improve operational efficiency, and reduce costs associated with maintaining outdated on-premise infrastructure.

By leveraging AWS’s robust cloud platform, we aimed to provide a scalable architecture that could easily adapt to the client’s evolving business needs, ensure high availability, and enhance security measures through AWS’s comprehensive suite of services and compliance certifications.

This strategic move allowed us to optimize performance, streamline operations, and position the client for future growth and innovation in the competitive financial services sector.
