Shwapno, one of the largest retail chain in Bangladesh, was rapidly expanding its online presence. As customer demand grew, their e-commerce platform started struggling to keep up. New features took weeks, sometimes months, to reach production because deployments were mostly manual and lacked proper planning. Developers often faced merge conflicts without a clear branching strategy, and whenever changes were pushed, they behaved differently across environments what worked in Dev sometimes broke in QA or Production. At the same time, the platform handled critical retail functions managing inventory, processing online orders, applying discounts, and integrating with third-party systems like SAP, MongoDB Atlas, Algolia, and City Bank for payments. Any downtime or performance issue meant frustrated customers and lost sales. To make matters worse, the lack of proper monitoring made it hard to pinpoint issues quickly, and compliance concerns around financial data added even more pressure.

The business needed: 

• A highly available e-commerce storefront that could handle peak traffic. 

• Faster feature releases with minimal downtime. 

• Integration with ERP (SAP) and payment services for smooth business workflows. 

• Secure, compliant infrastructure to protect customer and business data. 

• A reliable monitoring and alerting system to maintain service health. 

With microservices-driven architecture, multiple frontends, external integrations, and high scalability needs, DevOps practices were critical to ensure the platform's success. 

To address the challenges faced by Shwapno one of Bangladesh’s largest retail chains undergoing rapid digital expansion a comprehensive DevOps and AWS infrastructure audit was initiated. The assessment focused on deployment inefficiencies, environment inconsistencies, scalability gaps, external integrations, and compliance risks. A major portion of the strategy revolved around modernizing their deployment workflows, stabilizing their microservices-based architecture, and creating a unified environment pipeline that ensured consistency from development to production.

The first step was optimizing their version control and deployment structure. Shwapno’s developers previously relied on manual deployments, which often resulted in merge conflicts, unpredictable behavior across environments, and long release cycles. A structured Git branching model was introduced using GitHub, where feature branches flowed into develop, stage, and production. Each merge automatically triggered AWS CodeBuild pipelines, ensuring builds, linting, unit tests, and static code analysis through SonarQube were executed before any deployment. This automated process reduced manual errors and enabled predictable, traceable code releases.

Next, Shwapno’s environment management issues were addressed by provisioning dedicated Amazon EKS clusters for Development, Staging, and Production. MongoDB Atlas and Redis MQ were integrated with proper isolation rules, ensuring consistent behavior across all environments. Dependencies between microservices, frontend applications (Next.js and Angular), and third-party integrations such as SAP, Algolia, and City Bank payment gateway were aligned to ensure stable behavior across Dev → Stage → Prod.

Infrastructure as Code (IaC) was standardized using Terraform. This allowed Shwapno to manage critical infrastructure components including VPC, NAT Gateways, EKS clusters, autoscaling policies, and CloudFront distributions in a repeatable and auditable way. Automated deployments were streamlined using AWS CodeBuild , providing rollback capabilities and near-zero downtime deployments during feature releases.

To strengthen reliability, an end-to-end monitoring and observability framework was implemented. Prometheus collected metrics from microservices and EKS workloads, Jaeger captured application traces, and Grafana provided unified dashboards. MS Teams alerts were added for real-time notifications such as CPU spikes, pod restarts, or failures in MongoDB Atlas. This significantly improved operational visibility and reduced mean-time-to-detect (MTTD) during incidents.

Security and compliance were essential, given Shwapno’s handling of sensitive customer and payment data. AWS WAF was implemented to safeguard public APIs and the storefront from common attack vectors, while IAM least-privilege policies restricted internal access. VPC segmentation isolated critical workloads, and encryption was enforced across all services both at rest and in transit. Automated snapshot backups ensured data resiliency, and quarterly secrets rotation strengthened compliance readiness.

These combined efforts allowed Shwapno to stabilize their e-commerce operations, support higher traffic, facilitate rapid release cycles, and create a DevOps culture where deployments became predictable, secure, and observable.

Project Outcome

Following the implementation of these DevOps and cloud modernization strategies, Shwapno observed significant improvements across reliability, performance, deployment efficiency, and cost optimization.

The platform’s availability improved dramatically, with database uptime consistently reaching so much month over month. Failover drills verified that recovery scenarios could be handled within 5 to 10 minutes for most components, ensuring business continuity. Despite Redis and RabbitMQ being single-zone services, failure recovery was achieved within 30 minutes, mitigating major operational risks.

Performance across microservices showed strong improvements. The critical order-processing API maintained exceptional response times even during peak traffic. This directly enhanced customer experience and stabilized online order handling.

Cost optimization strategies such as autoscaling fine-tuning, resource rightsizing, and cleanup of redundant clusters reduced infrastructure spending from a baseline, achieving 15–20% cost savings month after month.

Security and compliance strengthened significantly for all sensitive data and quarterly secrets rotation. Operational readiness achieved maturity through monthly disaster recovery testing, ensuring high confidence in system resilience. Deployment reliability improved, with change failure rates now below 7%, showcasing the effectiveness of the updated CI/CD pipelines.

Most importantly, post-implementation stakeholder feedback rated the system performance and DevOps alignment as 5 out of 5, reflecting strong satisfaction from business and technical teams.
