Lambda Behind ALB Behind CloudFront: An Architecture Deep-Dive
Five ways to expose a Lambda function over HTTP. At least. AWS keeps adding more. Most teams pick API Gateway on day one and never revisit that decision. Fine. API Gateway handles a lot.
AWS Elastic Load Balancing: An Architecture Deep-Dive
I've yet to ship a production architecture on AWS that doesn't involve Elastic Load Balancing somewhere. Most teams slap a load balancer in front of their service and move on. Fair enough. That works until it doesn't. After debugging enough 502 cascades at 2 AM, I can tell you: the differences between the four ELB types, and what happens when you pick wrong, deserve way more attention than they typically get. So here it is. Patterns, trade-offs, and operational scars from years of running load-balanced architectures at scale.
