Architecture that scales up or down with demand
Customer-facing site under traffic spikes, with hit management solved
Database and hosting optimised to reduce cost of ownership
Data migration with AWS Database Migration Service
NRB Bazaar sells local and international products online to Bangladeshi customers, and wants to take local products to the international marketplace too. As a sister venture of MARS Solutions Limited, it has big plans — and a website that could not carry them. Three groups felt the limits:
A single-tier, non-scalable site works until the business succeeds. Then every surge in traffic becomes a hit-management problem, and every new idea becomes a question of whether the server can take it.
Brain Station 23 introduced a multi-tier, scalable AWS architecture on Linux, migrated the database with AWS DMS and the Schema Conversion Tool, and put the security, monitoring and delivery services around it that a growing store needs.
The result is a stable, customer-facing platform that scales with demand and costs less to own — letting the team focus on the business instead of the servers.
E-commerce growth is spiky. Campaigns, holidays and launches all arrive as sudden traffic, and a platform that cannot absorb it loses sales at the moment they are easiest to win.
Four pressures shaped the migration.
Together they pointed to one decision: move to an architecture that could scale up or down with the business, without sacrificing performance.
Bring it to a 30-minute call — we will come back with an architecture and a scoped estimate.
The new platform separates the tiers, moves the data safely, and wraps the whole thing in the AWS services that keep it fast, secure and observable.
The single-tier site was re-architected into a multi-tier AWS design on Linux-based EC2 behind an Application Load Balancer, able to scale up or down with demand.
AWS Database Migration Service moved the data with less time and effort, and the Schema Conversion Tool helped reshape the database for the new platform on Amazon RDS.
Database resources were optimised to save cost on cloud hosting, reducing the overall cost of ownership without wasting capacity.
Static assets on S3 are served through CloudFront, taking load off the application tier and speeding up pages for shoppers.
A dedicated VPC, Elastic IPs and KMS encryption secure the platform and its data.
CloudWatch, SNS and CloudTrail provide monitoring, alerts and an audit trail, so the team knows about issues before customers do.
The outcomes show up on the storefront and on the balance sheet.
Solving hit management stabilised NRB Bazaar’s customer-facing presence and improved customer retention. Greater online selling capability on AWS has translated into increased revenue.
The platform can now handle future growth and scale easily, which the old system was never designed to do. Database migration took less time and effort with DMS, and the optimised architecture lowers total cost of ownership, freeing the team to focus on its business goals.
The transferable lesson is that scalability is a business feature. Every new service NRB Bazaar wants to launch now starts from “how should we build it” rather than “can the server survive it”.
Separating the tiers is what made everything else possible: the load balancer, the CDN and the managed database each solve a different bottleneck, and none of them fit a single-server design.
You might be seeing slowdowns during campaigns, paying for capacity you only need occasionally, or putting off new features because the platform cannot take them. In every case, the first step is the same.
