3. Learn Core AWS Services

AWS offers a vast array of services. As an AWS Cloud Engineer, you’ll need to understand the core AWS services and know how to implement them. Some of the fundamental AWS services to focus on include:

1. Compute: EC2 (Elastic Compute Cloud) for virtual machines and Lambda for serverless computing.
2. Storage: S3 (Simple Storage Service) for scalable object storage and EBS (Elastic Block Store) for block storage.
3. Database: RDS (Relational Database Service) for managed databases and DynamoDB for NoSQL databases.
4. Networking: VPC (Virtual Private Cloud) for isolated cloud resources, Route 53 for DNS, and Elastic Load Balancer for distributing traffic.
5. Security: IAM for managing access permissions, CloudTrail for auditing, and AWS KMS (Key Management Service) for encryption.

Familiarize yourself with AWS by creating a free AWS account and experimenting with these services. AWS provides a Free Tier allowing beginners to try many services without incurring charges for the first 12 months.
