The Challenge

Duplicated routing driving unnecessary costs.

Each application service had its own routing and traffic management components, creating duplicated infrastructure that increased AWS costs as the platform grew.

Before

Duplicated infrastructure per service

  • Separate routing and traffic management components for each application service
  • Duplicated infrastructure resources increasing AWS costs as services grew
  • Complex routing and traffic management configuration
  • Higher operational effort for maintenance and troubleshooting
  • Difficulty scaling additional services efficiently
After

Centralized shared architecture

  • Centralized shared routing architecture using host-based routing
  • Single ALB handling traffic for all application services
  • Simplified traffic management configuration
  • Reduced infrastructure complexity across the staging environment
  • Easy onboarding path for future application services
Our Approach

Three weeks. Zero downtime.

We assessed the existing architecture, consolidated duplicated components, and validated full functionality across all services within a focused 2–3 week engagement.

Step 1 · Week 1 · Infrastructure Assessment

Infrastructure Assessment

  • Reviewed existing routing and traffic management architecture
  • Identified duplicated infrastructure components across application services
  • Assessed cost impact of separate routing per service
  • Designed centralized shared architecture using host-based routing
  • Planned migration strategy to ensure zero downtime
Step 2 · Week 2 · Consolidation & Migration

Consolidation & Migration

  • Consolidated multiple routing components into shared architecture
  • Implemented host-based routing rules for all application services
  • Migrated traffic from individual components to centralized ALB
  • Removed unnecessary infrastructure resources after migration
  • Applied resource grouping and tagging for improved cost visibility
Step 3 · Week 3 · Validation & Optimization

Validation & Optimization

  • Validated all application services for uninterrupted functionality
  • Verified routing rules and traffic flow for each service
  • Confirmed cost reduction across routing and traffic management
  • Documented new architecture and operational procedures
  • Established process for onboarding future services
Results

What changed, permanently.

Consolidating duplicated routing into a centralized shared architecture delivered measurable cost savings, simplified operations, and set the stage for effortless scaling.

30–40% Cost Reduction

AWS infrastructure cost related to routing and traffic management reduced by consolidating duplicated components.

30–40%

Simplified Architecture

Centralized routing eliminated per-service infrastructure duplication, reducing complexity and maintenance effort.

Faster Service Onboarding

New application services can be added by simply creating a host-based routing rule — no new infrastructure required.

Operational Efficiency

Simplified maintenance and troubleshooting with reduced infrastructure footprint and improved cost visibility.

The centralized routing approach reduced infrastructure complexity while maintaining application performance and availability across all services.
