VPC is the number one topic where engineers make security errors. Opening 0.0.0.0/0 because "it works", confusing Security Groups with NACLs, or not knowing why a NAT Gateway is needed — these are real production incidents. We teach VPC the way a network engineer would, applied to AWS.

Attaching AdministratorAccess to everything "because it works" is one of the most dangerous habits in cloud. Real IAM is about writing precise JSON policies, understanding the evaluation logic, and knowing when a Role beats a User. We teach IAM the way an AWS security engineer would audit your account.

Teams pay for over-provisioned EC2 instances because they don't trust their Auto Scaling to work. Or they misconfigure health checks so the load balancer keeps sending traffic to unhealthy instances. We teach the failure modes first — so your scaling is reliable when it matters, not just in a demo.

Most engineers only look at CloudWatch when something breaks. Real SRE teams build dashboards, set proactive alarms, and use Logs Insights to find anomalies before users notice. This module teaches you to build the observability layer that prevents incidents, not just responds to them.

Most courses teach cloud-native but skip migration entirely. The reality is that billions of dollars of workloads still run on-premises, and companies pay serious money for engineers who can move them safely. We teach the strategy frameworks and the actual AWS tools — because real migration projects follow a process, not a tutorial.

Most engineers learn troubleshooting the hard way — by being paged at 2am and clicking randomly until something works. There's a better way. AWS has a structured methodology for diagnosing every category of problem — connectivity, performance, permissions, configuration — and this module teaches it before you're in production under pressure.
