"ECS vs EKS - which to choose: ECS: - Simpler to learn and operate - Tighter AWS integration - Lower operational overhead - Good for AWS-only workloads - Cheaper for small deployments EKS: - Industry standard Kubernetes - Portable across clouds - Larger ecosystem and community - Better for complex orchestration - More job opportunities New to containers Start with ECS"

"AWS: ALB vs NLB Application Load Balancer (ALB) - Works at Layer X (HTTP/HTTPS) - Routes based on URL path headers hostnames - Perfect for web apps & microservices - SSL termination built-in - Slower but smarter routing Network Load Balancer (NLB) - Works at Layer X (TCP/UDP) - Routes based on IP & port only - Ultra-fast millions of requests/sec - Static IP support - Best for extreme performance needs Use ALB When - Running web applications - Need path-based routing (/api /admin) - Host-based routing (app1.com app2.com) - Want AWS WAF integration Use NLB When - Need extreme performance/low"

"I'll try to keep the answer as simple as possible. User-data only runs once at instance launch while Ansible lets you update configurations patch software or modify settings on already-running servers without restarting them. Ansible playbooks can be run multiple times and will ensure all servers stay in the desired state even if someone manually changed something. Learning Objective - This is a beginner project and configuration management tools are essential in real DevOps workflows. While the particular steps could be covered in the user-data of the EC2 instance I think it's good to"

"Moved from Heroku to AWS ECS because Heroku cost was killing us.

But we now spend XX hours/week on infrastructure. The hidden cost of ownership is real. Sometimes premium platforms are worth it"
