Client Overview
Our client is an investment company operating in the Middle East, with clients also based in the region. They are a fintech company managing on-premises infrastructure. Their applications were hosted manually on IIS servers, including both monolithic and backend services. As their user base and development needs grew, managing everything manually became a major challenge. They needed a cloud-native, automated solution that could grow with their business.
Problem Statement
The client had a fully manual, on-premises setup where .NET applications were deployed using IIS. This setup lacked automation, scalability, and a reliable disaster recovery plan. It also created performance and maintenance issues, especially during high traffic. The client wanted to modernize their infrastructure to reduce downtime, improve reliability, and streamline operations.
Requirement Gathering
The client required a modernized infrastructure to eliminate manual deployments, support auto-scaling for fluctuating traffic, and centralize management with robust monitoring. The solution needed built-in disaster recovery to ensure high availability (99% uptime) while meeting strict compliance and security standards.
Our Approach
We proposed a migration to Oracle Cloud Infrastructure (OCI), using the Jeddah region for low-latency access and regulatory alignment. Our key strategy included:
Microservices on OKE
We converted the backend into Microservices and deployed them on a Kubernetes cluster(OKE).
Containerized .NET Monoliths
Containerizing monolithic .NET applications and deploying them on OCI Container Instances, which is more suitable for workloads not yet broken into microservices.
GitHub Actions CI/CD
Setting up GitHub Actions for continuous integration and automated deployment.
Auto-Scaling & Disaster Recovery
Enabling auto-scaling, monitoring, and disaster recovery across the environment.
This approach allowed for flexible scaling, efficient resource use, and better separation of workloads.
Implementation
Kubernetes Deployment on OCI
Containerized all backend services and deployed them on Kubernetes within OCI
Containerized Monolithic Apps
Packaged monolithic applications into Docker containers and deployed them to OCI Container Instances.
GitHub Actions CI/CD
Implemented GitHub Actions to automate deployment from code push to production.
Auto-Scaling & Monitoring
Enabled auto-scaling and centralized logging and monitoring.
Disaster Recovery Setup
Set up disaster recovery policies using OCI’s built-in features.
End-to-End Testing
Performed end-to-end testing to ensure system reliability and readiness.
Compliance & Regulatory Adherence
We setup whole solution making sure that we follow the compliance and regulatory requirements within the region.
Technologies Used
Oracle Cloud Infrastructure(OCI)
Kubernetes
Docker
Container Registries
GitHub
WSL
Visual Studio CodeOutcome
The client now operates on a modern, cloud-based infrastructure that is fully automated and scalable. Their microservices run on Kubernetes, scaling dynamically based on traffic demands, while monolithic applications are efficiently managed using OCI Container Instances. Developers can deploy code seamlessly through GitHub without any manual intervention. The entire system is now more resilient, cost-effective, and easier to manage. Uptime has significantly improved, and a robust disaster recovery plan is firmly in place.
