Client: Parcel Delivery App
Services Provided: Cloud Infrastructure Setup, Migration, Monitoring Integration
Technologies: Oracle Cloud Infrastructure (OCI), Node.js, Angular, Mosquitto MQTT, SSL, Load Balancer, Grafana, Prometheus

Project Overview:

Parcel Delivery App , a technology-driven platform, required a seamless migration from AWS to Oracle Cloud Infrastructure (OCI) to improve scalability, security, and performance. The scope involved setting up backend and frontend systems, ensuring secure communication, implementing high availability with a load balancer, and integrating advanced monitoring tools for proactive system management.

Challenges:

• Migrating the entire system from AWS to OCI without interrupting service.
• Setting up a secure, scalable infrastructure that meets performance and availability requirements.
• Ensuring seamless real-time communication with Mosquitto MQTT and secure SSL
• Implementing robust monitoring and alerting systems for continuous performance tracking.

Solution Delivered:

• Backend & Frontend Deployment:
  • Utilized OCI Compute Services to set up the backend in Node.js and the frontend in Angular, ensuring that the infrastructure met performance, security, and scalability goals.
• Mosquitto MQTT & SSL Integration:
  • Deployed Mosquitto MQTT on OCI compute instances to handle real-time communication and integrated SSL certificates to secure all data transmissions.
• High Availability with Load Balancer:
  • Configured an OCI Load Balancer to ensure high availability for the web application, distributing traffic effectively across multiple instances and maintaining reliability during peak loads.
• Encrypted Block Storage & Security:
  • Set up OCI Block Storage with encryption enabled, securing data with encryption keys stored securely in OCI Vault, ensuring both data integrity and confidentiality.
• Advanced Monitoring Integration:
  • Integrated Grafana and Prometheus to provide real-time monitoring and alerts for system health, along with configuring OCI’s native monitoring tools to track performance and resource usage.

Roles & Responsibilities:

• Architecture & Requirement Analysis:
  • Analyzed the project’s requirements and designed a robust and scalable architecture. Ensured that the architecture was feasible and well-tested before deployment.
• AWS to OCI Migration:
  • Managed the smooth migration of the entire system from AWS to OCI, ensuring minimal disruption and improved infrastructure performance.
• Code Review & Database Design:
  • Conducted thorough code reviews and restructured the database architecture to optimize performance and ensure scalability.
• Monitoring Tools Integration:
  • Integrated Grafana and Prometheus for comprehensive system monitoring, ensuring performance visibility and alert configuration for critical events.

Outcome:

The Parcel Delivery App project was completed successfully within the designated timeframe, resulting in:

• Improved performance with the scalable OCI infrastructure.
• Enhanced security through encrypted block storage and secure communication channels.
• High availability of the web application, ensuring minimal downtime and reliable performance during peak traffic.
• Real-time monitoring and proactive system management with integrated tools, ensuring swift response to any performance issues.

Parcel Delivery App now operates on a more secure, scalable, and efficient infrastructure, fully equipped for future growth.
