Analysis and Audit Cloud Optimization Migration to Cloud

A FinTech company operates in a sophisticated technological ecosystem comprising both physical and virtual servers hosted in a dedicated data center. Their infrastructure includes critical components such as web servers, a API, and a mix of database management systems. Despite the robustness of this setup, the company grappled with high operational costs, limited scalability, and significant management overhead due to manual processes.



Legacy Ecosystem

Optimizing infrastructure not only reduces operational costs but also mitigates risks associated with manual management and outdated technologies. This migration to a modernized, cloud-based system enables fintech companies to leverage advanced technologies, automate processes, and scale efficiently in response to market demands, thus positioning themselves for sustainable growth and innovation in a highly competitive industry.

Addressing challenges was crucial for the fintech company to streamline their operations, reduce costs, enhance security, and improve their ability to scale efficiently. The proposed cloud migration and infrastructure modernization aimed to resolve these issues, providing a more agile, secure, and cost-effective solution that would support the company’s long-term growth and success.

Strategic Solutions

Maintain Current Infrastructure on Physical Servers

This approach involved CSHARK taking over the management of the existing physical servers without any significant changes to the infrastructure. The primary advantage was operational stability, as the current setup would remain intact, thus avoiding migration risks. However, this option did not address the high maintenance costs or scalability issues.

Modernize Infrastructure and Maintain on Physical Servers

Here, the proposal was to implement a Kubernetes cluster on the existing hardware. This modernization would improve resource management and allow for gradual cloud migration. While this option offered better resource utilization and flexibility, it required substantial initial setup and ongoing maintenance of the on-premise hardware and software.

Lift and Shift to Cloud

The Lift and Shift strategy entailed migrating the current infrastructure to AWS with minimal changes. This method included two variations. Direct Replication to AWS EC2 that would involve transferring existing virtual machines to AWS EC2 instances. Hybrid Approach where applications would run on AWS EC2, while databases would leverage AWS managed services. Both variations promised a straightforward migration with minimal operational disruption. However, they did not fully capitalize on the cost optimization and advanced features offered by AWS.

Modernize and Migrate to Cloud

The recommended solution was to modernize and migrate the infrastructure to a cloud-native setup using AWS ECS for container management and AWS managed services for databases. This strategy promised high scalability, reduced administrative overhead, and long-term cost efficiency. Despite the complexity and higher initial costs, this approach aligned best with the fintech company’s needs for a scalable, flexible, and cost-effective solution.

Preparation Phase

The implementation plan began with a detailed preparation phase. CSHARK’s team initiated the process by conducting a thorough review of existing infrastructure. This involved examining the physical and virtual servers, the API, and the various database management systems in use. The team worked closely with the client’s IT team to exchange knowledge and insights about the current setup. An optional step in this phase was for CSHARK developers to perform analysis of the application code to identify areas for optimization and ensure compatibility with the anticipated cloud environment.


The migration to a containerized architecture managed by AWS ECS, coupled with AWS managed database services, presented the client with significant benefits. This strategic move enhanced scalability, flexibility, and cost efficiency, providing a robust foundation for future growth. Although the initial setup was complex and costly, the long-term benefits included reduced operational costs, improved resource utilization, and streamlined management processes.
