🎯 What You'll Learn:
• Horizontal scaling vs vertical scaling concepts
• Load balancing algorithms (Round Robin, Weighted Round Robin)
• Service Level Objectives: Achieving sub-200ms response times
• Component vs Building Block architecture patterns
• Nginx load balancer configuration and setup
• Health checks and failure handling in distributed systems
• Infrastructure as Code with Terraform for scaling
• Auto-scaling concepts with Kubernetes

🛠️ Practical Implementation:
• Complete demo with "Like Service" backend component
• Docker containerization for multiple service instances
• Nginx load balancer configuration and testing
• Terraform infrastructure provisioning
• Real-world traffic distribution and failover testing
