ShopVerse: Zero-Downtime E-commerce Migration to AWS
ShopVerse E-commerce Cloud Migration & Performance Modernization
SCOPE
What We Did
AWS Landing Zone & Network
Multi-account landing zone with Organizations & SCPs, secure VPC design, and Transit Gateway for scalable, isolated environments.
App Modernization on ECS Fargate
Containerized services and deployed on ECS Fargate with autoscaling, blue/green releases, and capacity controls for peak events.
Database Migration to Aurora
MySQL migration to Amazon Aurora using AWS DMS (CDC) for near-zero downtime cutover and read-replica promotion.
Caching & Media Acceleration
ElastiCache (Redis) for sessions/catalog, S3 + CloudFront for CDN, and image optimization for faster page loads.
Security & Compliance
WAF, Shield, IAM least-privilege, KMS encryption, audit trails, and PCI-aligned controls across workloads.
Observability & CI/CD
Unified logging/metrics/tracing via CloudWatch + Datadog, GitHub Actions pipelines, and Terraform IaC.
Outcomes Delivered
Zero-downtime cutover during peak season
p95 latency reduced by 35% across PDP/Checkout
Infrastructure cost reduced by 27% via rightsizing & Savings Plans
Conversion rate increased by 18% after performance optimizations
Uptime raised to 99.95% with multi-AZ Aurora and autoscaling services
BRIEF
ShopVerse is a high-traffic marketplace serving 40M+ monthly pageviews with extreme seasonal spikes.
Objective: exit aging on-prem hardware before the holidays, improve reliability, and reduce costs—without losing a single sale.
CHALLENGE
On-prem monolith and legacy infra strained under peak traffic, risking outages and cart abandonment.
Tight timeline before the holiday season; strict PCI requirements; need for measurable performance and cost gains.
ShopVerse implemented a comprehensive migration and modernization program:
AWS LANDING ZONE & NETWORKING
Established multi-account governance, VPC segmentation, Transit Gateway, and secure connectivity to support staged migration.
CONTAINERIZATION & ECS FARGATE
Broke out services, containerized workloads, and enabled blue/green deploys with autoscaling for predictable peak performance.
AURORA MIGRATION WITH DMS (CDC)
Used AWS DMS change data capture to keep databases in sync; promoted read replicas and switched traffic with zero customer impact.
OBSERVABILITY, SECURITY & CI/CD
Implemented WAF/Shield, KMS encryption, centralized logging/metrics/tracing, and GitHub Actions + Terraform for repeatable releases.
Key Results & Impact
The comprehensive strategy delivered exceptional results across all key performance indicators, establishing Vero Diamonds as a leader in the luxury lab-grown diamond market.
Infrastructure Cost Reduction
Savings Plans, rightsizing, and autoscaling cut baseline spend significantly.
Downtime During Cutover
Blue/green strategy with weighted DNS ensured uninterrupted checkout.
p95 Latency Improvement
Caching, CDN, and container tuning reduced page and API response times.
Post-Migration Uptime
Multi-AZ Aurora, health checks, and autoscaling improved overall availability.
Holiday-Ready, Faster, and Cheaper
By pairing a zero-downtime migration with targeted modernization, ShopVerse entered peak season with faster pages, higher conversion, and materially lower cloud spend.
