AWS development involves utilizing AWS resources like EC2, S3, and Lambda to develop apps, services, and other products that can be easily scaled up or down in the cloud. The best practices for AWS development include using CloudFormation to model infrastructure, IAM for access control, S3 for storage, EC2 for computing, CodeDeploy for deployments, CloudWatch for monitoring, RDS for databases, Lambda for serverless computing, CloudTrail for logging and auditing, and Security Hub for security scanning. Users can get started with AWS by creating an account, selecting services, and generating resources through the AWS website or programmatically using the CLI or SDKs. They can also benefit from the AWS free tier to experiment
