Introduction
HNAK, a flagship brand under Al Musbah Group, is one of Saudi Arabia’s biggest retail names, selling electronics, fashion, lifestyle, and home products. Discover how HNAK modernized its container platform by migrating from EC2-based ECS to AWS Fargate, improving scalability, deployment speed, and operational efficiency through a fully managed, serverless container architecture.
Business Challenge
Scaling Performance Without Operational Overhead
As a high-traffic eCommerce brand, HNAK operates in an environment where speed, availability, and consistency directly impact revenue and customer experience. While the platform was already containerized, the underlying EC2-managed compute model introduced increasing operational complexity as traffic patterns became more dynamic and customer expectations continued to rise.
The engineering team faced growing challenges around:
- Managing EC2 capacity for unpredictable traffic spikes
- Slow container startup during scaling events
- Manual oversight of compute health and scaling behavior
- Balancing performance requirements with cost efficiency
Although functional, the existing setup limited agility and placed unnecessary operational load on engineering teams, making it difficult to scale efficiently without increasing infrastructure overhead.
Architecture Before: ECS on EC2 at Scale
In the previous architecture:
- ECS services ran on self-managed EC2 instances
- Scaling required pre-provisioned capacity
- Large Ubuntu-based container images increased startup latency
- Engineering teams were responsible for OS patching, capacity planning, and instance lifecycle management
This model performed well under steady traffic but showed inconsistent performance and delayed scaling during peak demand.
Business Solution
Architecture After: Serverless Containers with AWS Fargate
Krish redesigned the platform using a serverless container architecture built on Amazon ECS with AWS Fargate, eliminating the need to manage underlying compute infrastructure.
Key Architectural Decisions
- Migrated ECS services from EC2 to AWS Fargate
- Introduced Application Load Balancer (ALB) for traffic distribution
- Optimized containers using Alpine Linux–based images
- Centralized observability and auditing using AWS native services
With Fargate, AWS assumes responsibility for:
- Compute provisioning and scaling
- OS patching and maintenance
- Capacity availability and isolation
This allowed the engineering team to focus entirely on application behavior and delivery.
DevOps & Container Optimization Strategy
Beyond the infrastructure shift, Krish applied several DevOps-led optimizations:
Container Optimization
- Rebuilt Next.js containers using lightweight Alpine Linux
- Reduced container image size significantly
- Optimized build layers to minimize image pull times
- Removed unnecessary runtime dependencies
CI/CD Automation
- AWS CodeCommit, CodeBuild, and CodePipeline enabled automated builds and deployments
- Amazon ECR used as a centralized container registry
- Predictable and repeatable deployments across environments
Observability & Governance
- Amazon CloudWatch for metrics, logs, and alarms
- AWS CloudTrail & AWS Config for auditability and compliance tracking
- AWS Trusted Advisor for cost and security recommendations
Operational Outcomes & Well-Architected Alignment
The new platform aligns directly with AWS Well-Architected Framework pillars, and HNAK saw a significant positive impact on its performance efficiency, operations, ROI, and governance:
Performance Efficiency
- 40% reduction in container startup time
- Faster, smoother scaling during peak traffic events
Operational Excellence
- Zero manual EC2 capacity management
- Simplified deployment and rollback processes
- Reduced operational toil for engineering teams
Cost Optimization
- Elimination of idle EC2 capacity
- Compute consumption aligned directly with workload demand
Security & Governance
- IAM-based access control
- VPC-isolated networking with security groups
- Continuous audit visibility via CloudTrail and Config
Business Impact at Scale
The modernization delivered immediate and measurable value:
- Faster scaling without performance degradation
- Increased platform stability during high-traffic periods
- Reduced operational overhead for engineering teams
- Improved release velocity and deployment confidence
By shifting to a serverless container model, HNAK transformed its infrastructure from a maintenance-heavy environment into a fully automated, resilient, and future-ready platform.
