Implement Load Balancing and High Availability Setup

## Overview
Configure load balancing and high availability to ensure the platform can handle production loads and failures.

## Business Value
HA ensures uptime and load balancing enables horizontal scaling for growth.

## Current State
- Single instance deployment
- No load balancing
- No failover mechanisms

## Subtasks
- [ ] Design HA architecture
- [ ] Set up load balancer
- [ ] Configure multiple instances
- [ ] Implement health checks
- [ ] Add failover mechanisms
- [ ] Test failover scenarios
- [ ] Document HA setup

## Implementation Steps
1. Design architecture
2. Set up load balancer
3. Configure multiple instances
4. Add health checks
5. Test failover

## Acceptance Criteria
- [ ] Load balancer distributes traffic
- [ ] Health checks work
- [ ] Failover is automatic
- [ ] Zero downtime deployments
- [ ] Documentation exists

## Estimated Effort
- Hours: 24-32
- Complexity: High
