Core AWS Services (EC2, S3, VPC)
Deep familiarity with the foundational AWS building blocks for compute, object storage, and network isolation.
Identity & Access Management (IAM)
Designing least-privilege IAM roles, policies, and permission boundaries to keep AWS accounts secure and auditable.
Networking (VPC, Route 53)
Building and securing VPCs, subnets, routing, security groups, and DNS to connect services reliably and safely.

Provisioning AWS resources declaratively with CloudFormation, the CDK, or Terraform for repeatable, reviewable deployments.
Compute & Serverless (Lambda, ECS, EKS)
Choosing and operating the right compute model — servers, containers, or serverless functions — for each workload.
Managed Databases (RDS, DynamoDB)
Running relational and NoSQL data stores on AWS with appropriate scaling, backup, and availability configurations.
Monitoring with CloudWatch
Collecting metrics, logs, and alarms to observe workloads and respond to problems before they escalate.

Cloud Migration
Planning and executing lift-and-shift or re-platform migrations of workloads into AWS.
Associated Skills
Broader skills that round out a well-equipped AWS Cloud Engineer.
Linux Administration
Operating and troubleshooting the Linux instances that host most AWS workloads.
