AWS Infrastructure Implementation

Customer Name : : CSH Direk

Partner Name : Onedata Software Solutions

Onedata Software Solutions transformed CSH Direk’s single-server environment into a secure, highly available AWS infrastructure. Using EC2, RDS Multi-AZ, Auto Scaling, ALB, ACM, CloudWatch, CloudTrail, and VPC, the solution improved application performance, reduced operational overhead, enhanced reliability, and ensured compliance with FinTech security standards.

About the Customer

CSH Direk is a FinTech company delivering secure, reliable, and scalable digital financial services. As part of its growth strategy, the company developed a custom financial application stack that required a robust hosting environment. The key business need was to deploy this application on AWS with best practices in security, reliability, scalability, and cost optimization to ensure compliance and long-term growth.

Challenges Before AWS

While CSH Direk had successfully developed its core application, it lacked a cloud infrastructure that could support production-grade operations. Key challenges included:

Application Hosting Gaps – The development environment was not optimized for production workloads.
Scalability Needs – Infrastructure had to support unpredictable spikes in financial transactions and customer traffic.
Database Reliability – Required a managed, secure, and highly available database solution to safeguard financial data.
Security & Compliance – FinTech operations required strict access control, monitoring, and encryption.
Operational Efficiency – The company wanted to minimize manual server management and focus on product development.

Objectives

The AWS implementation aimed to:

Host the custom-developed application in a secure and production-ready environment.
Ensure high availability and automated failover for business continuity.
Strengthen security posture with IAM policies, encryption, and logging.
Optimize performance and scalability with AWS-native services.
Reduce operational overhead through managed services.

AWS Architecture Implemented

The infrastructure was designed and deployed using AWS-native services to balance scalability, reliability, and cost-efficiency:

Amazon EC2 – Hosted the application stack (backend APIs, frontend services, and Node.js/PHP components) with Nginx.
Amazon RDS (MySQL) – Provided a fully managed database with multi-AZ deployment, automated backups, and monitoring.
Application Load Balancer (ALB) – Ensured high availability and distributed traffic across EC2 instances.
Auto Scaling – Automatically adjusts compute resources to meet demand during peak usage.
AWS Certificate Manager (ACM) – Managed SSL/TLS certificates for secure HTTPS communication.
Amazon VPC – Hosted workloads in isolated private/public subnets with security group rules for controlled access.
AWS CloudWatch & CloudTrail – Delivered monitoring, logging, and auditing for compliance and operational insights.
IAM Roles & Policies – Enforced least-privilege access control for administrators and applications.

Implementation Approach

Assessment & Design
- Reviewed application requirements and designed a secure, scalable AWS architecture.
- Defined VPC network topology with private subnets for RDS and public subnets for EC2.
Infrastructure Setup
- Provisioned EC2 instances for application hosting.
- Deployed Amazon RDS with Multi-AZ for resilience.
- Configured IAM roles, security groups, and network ACLs.
Application Hosting
- Deployed backend (PHP/Node.js APIs) and frontend (Angular build) on EC2 with Nginx.
- Integrated RDS for financial data storage and optimized queries.
Security & Compliance
- Applied for SSL/TLS certificates via ACM.
- Enabled CloudTrail for audit logging and CloudWatch for operational monitoring.
- Implemented encryption at rest (RDS) and in transit (HTTPS).
Testing & Optimization
- Performed load and performance testing.
- Tuned Auto Scaling policies to handle transaction spikes.
- Validated backup/restore and failover processes.

Results Achieved

Secure Production Hosting – Application hosted in a secure AWS environment with IAM, SSL, and network isolation.
Improved Reliability – RDS Multi-AZ and Auto Scaling reduced downtime risk and ensured resilience.
Enhanced Performance – Load-balanced EC2 instances improved response times by ~50%.
Compliance-Ready Architecture – Logging, encryption, and monitoring supported FinTech security requirements.
Operational Efficiency – AWS managed services reduced overhead, enabling CSH Direk to focus on innovation.

Key Takeaways

The AWS infrastructure implementation empowered CSH Direk to:

Successfully host and run its custom FinTech application on AWS.
Deliver secure, reliable, and scalable digital financial services.
Build a future-proof foundation ready for additional automation, analytics, and growth.
