Scaling Cloud Infrastructure

Enterprise-grade AWS infrastructure that grows with your healthcare business while optimizing costs and maintaining 99.99% uptime.

THE CHALLENGE

Managing Explosive Growth on AWS

A medical device company's IoT platform was experiencing 300% monthly growth but their AWS infrastructure was becoming a bottleneck, with costs spiraling out of control and frequent downtime during peak usage.

$45k monthly AWS bill with poor performance

Over-provisioned resources and inefficient architecture

95% uptime during peak hours

Critical medical devices losing connectivity during high usage

No disaster recovery plan

Single point of failure with no multi-region backup

Cloud infrastructure
OUR SOLUTION

Enterprise AWS Architecture

Auto-Scaling Architecture

Implemented EKS with horizontal pod autoscaling and cluster autoscaling to handle traffic spikes automatically while minimizing costs.

  • • AWS EKS with Karpenter
  • • Application Load Balancer
  • • Target tracking scaling policies

Multi-Region Setup

Deployed across 3 AWS regions with active-passive failover and cross-region data replication for 99.99% availability.

  • • Primary: us-east-1
  • • Secondary: us-west-2, eu-west-1
  • • Route 53 health checks

Cost Optimization

Implemented Spot instances, Reserved instances, and intelligent resource scheduling to reduce costs by 60% while improving performance.

  • • 70% Spot instances for batch processing
  • • Reserved instances for baseline load
  • • AWS Cost Explorer automation
