About The Project

Airzen is a digital eSIM platform that allows users to purchase and manage international connectivity online. As the platform’s user base expanded, its legacy standalone server setup began bottlenecking operations. Deployments required risky manual intervention, horizontal scaling was non-existent, and sudden traffic spikes frequently degraded application performance.

They approached us seeking a more reliable infrastructure to support future growth. The platform needed automated deployments, better security, improved session management, and the ability to handle increasing traffic without service interruptions.

We redesigned the entire infrastructure using AWS services and a containerized deployment approach. The new architecture reduced operational overhead and gave the platform a more stable foundation for future growth.

Key Project Deliverables

We delivered solutions that improved infrastructure management, deployment automation, security, and application performance.

AWS ECS Fargate Infrastructure

We deployed the app on AWS ECS Fargate to simplify infrastructure management and support automatic scaling.

Dockerized Backend Deployment

We containerized the Laravel app to create consistent deployment environments across staging and production.

Load Balancing

We configured an Application Load Balancer to distribute traffic across running containers and improve availability.

Secure Cloud Architecture

We built a secure VPC with public and private subnets to separate application and database resources.

Database & Caching Setup

We configured Amazon RDS MySQL and ElastiCache Redis to improve performance, session management, and reliability.

CI/CD Automation

We implemented GitHub Actions pipelines to automate application deployments and reduce manual work.

Major Project Challenges

The biggest challenge was replacing the existing standalone infrastructure without disrupting platform operations. The previous environment required manual deployments, experienced downtime during releases, and had limited scalability.

Deployment automation was another challenge. Every release required direct server access, which increased deployment time and created unnecessary risks during updates. As traffic continued to grow, the platform also faced scalability issues. The infrastructure could not automatically handle traffic spikes, resulting in performance issues during busy periods.

Security improvements were equally important. Some services were publicly exposed, and the platform needed stronger network isolation and better traffic protection. Session stability also needed attention because authentication and user sessions became unreliable during periods of high load.

Solutions & Impact

We rebuilt the infrastructure using AWS cloud services and a container-based deployment model. The new environment was designed to improve stability, simplify deployments, and support future growth.

To improve reliability and security, we implemented several infrastructure upgrades.

Deployed applications using AWS ECS Fargate.
Containerized the Laravel backend with Docker.
Configured Application Load Balancer for traffic distribution.
Built a secure VPC architecture with private subnets.
Implemented Amazon RDS for managed database services.
Configured ElastiCache Redis for sessions and caching.
Added AWS WAF for application security.
Integrated Amazon S3 for file storage.
Configured Route 53 for DNS management.
Built CI/CD pipelines using GitHub Actions.
Enabled ECS auto scaling based on traffic demand.
Added CloudWatch monitoring and centralized logging.

The new infrastructure reduced manual deployment work and improved platform stability. Releases became faster and more predictable, while auto scaling helped the platform handle traffic spikes without performance issues. Security was also improved through private networking, managed services, and application-level protection.
