IAM

```bash

List users

aws iam list-users

Create role

aws iam create-role
--role-name agent-role
--assume-role-policy-document file://trust-policy.json

Attach policy

--role-name agent-role
--policy-arn arn:aws:iam::aws:policy/AmazonS3ReadOnlyAccess ```

Boto3 Python SDK

```python import boto3

S3 operations

s3 = boto3.client('s3')

Upload file

s3.upload_file('local.txt', 'bucket-name', 'remote.txt')

Download file

s3.download_file('bucket-name', 'remote.txt', 'local.txt')

List objects

response = s3.list_objects_v2(Bucket='bucket-name', Prefix='prefix/') for obj in response.get('Contents', []): print(obj['Key'])

EC2 operations

ec2 = boto3.resource('ec2')

Get all running instances

instances = ec2.instances.filter( Filters=[{'Name': 'instance-state-name', 'Values': ['running']}] ) for instance in instances: print(f"{instance.id}: {instance.instance_type}")

Lambda invocation

lambda_client = boto3.client('lambda') response = lambda_client.invoke( FunctionName='my-function', InvocationType='RequestResponse', Payload=json.dumps({'key': 'value'}) ) result = json.loads(response['Payload'].read()) ```

Terraform AWS Resources

```hcl

VPC

resource "aws_vpc" "main" { cidr_block = "10.0.0.0/16" enable_dns_hostnames = true enable_dns_support = true

tags = { Name = "golden-armada-vpc" } }

EKS Cluster

resource "aws_eks_cluster" "main" { name = "golden-armada-cluster" role_arn = aws_iam_role.cluster.arn version = "1.28"

vpc_config { subnet_ids = aws_subnet.private[*].id } }

RDS Instance

resource "aws_db_instance" "main" { identifier = "golden-armada-db" engine = "postgres" engine_version = "15" instance_class = "db.t3.medium" allocated_storage = 20

db_name = "golden_armada" username = var.db_username password = var.db_password

vpc_security_group_ids = [aws_security_group.db.id] db_subnet_group_name = aws_db_subnet_group.main.name

skip_final_snapshot = true } ```

Best Practices

1. Use IAM Roles instead of access keys
2. Enable CloudTrail for audit logging
3. Tag all resources for cost tracking
4. Use VPC for network isolation
5. Enable encryption at rest and in transit
6. Implement least privilege IAM policies
