AWS EC2 Deployment Skill

Deploy and manage EC2 instances with production-ready configurations.

Quick Reference

Attribute	Value
AWS Service	EC2
Complexity	Medium
Est. Time	5-15 min
Prerequisites	VPC, Security Group, Key Pair

Parameters

Required

Parameter	Type	Description	Validation
instance_type	string	EC2 instance type	Valid type (m6i.large)
ami_id	string	AMI ID	ami-[a-z0-9]{17}
subnet_id	string	Target subnet	subnet-[a-z0-9]{17}
security_group_ids	array	Security groups	Non-empty array

Optional

Parameter	Type	Default	Description
key_name	string	null	SSH key pair name
iam_instance_profile	string	null	IAM role ARN
user_data	string	null	Base64 startup script
ebs_optimized	bool	true	EBS optimization
monitoring	bool	true	Detailed monitoring

Implementation

Launch Instance

aws ec2 run-instances \
  --image-id ami-0abcdef1234567890 \
  --instance-type m6i.large \
  --subnet-id subnet-12345678 \
  --security-group-ids sg-12345678 \
  --key-name my-key \
  --iam-instance-profile Name=MyRole \
  --ebs-optimized \
  --monitoring Enabled=true \
  --metadata-options HttpTokens=required \
  --tag-specifications 'ResourceType=instance,Tags=[{Key=Name,Value=MyServer}]'

User Data Script

#!/bin/bash
set -e
yum update -y
yum install -y docker
systemctl enable docker
systemctl start docker

Retry Logic

def launch_with_retry(params, max_retries=3):
    for attempt in range(max_retries):
        try:
            return ec2.run_instances(**params)
        except ec2.exceptions.InsufficientInstanceCapacity:
            params['SubnetId'] = get_alternate_subnet()
            time.sleep(2 ** attempt)
    raise Exception("Failed to launch instance")

Troubleshooting

Common Issues

Symptom	Cause	Solution
InsufficientInstanceCapacity	AZ full	Try different AZ
InvalidAMIID	AMI not in region	Copy AMI
Unauthorized	IAM missing	Check permissions
Pending forever	ENI issue	Check subnet IPs

Debug Checklist

AMI exists in target region?
Subnet has available IPs?
Security group allows traffic?
Key pair exists?
IMDSv2 configured?

Instance Selection Guide

Workload	Family	Key Feature
Web/API	M6i, M7g	Balanced
Compute	C6i, C7g	High CPU
Memory	R6i, X2idn	High memory
GPU/ML	P4d, G5	NVIDIA GPU

Cost Optimization

Strategy	Savings
Reserved Instances	30-60%
Savings Plans	30-72%
Spot Instances	Up to 90%
Right-sizing	10-50%

Test Template

def test_ec2_launch():
    # Arrange
    params = {
        "ImageId": get_latest_amazon_linux_ami(),
        "InstanceType": "t3.micro",
        "MaxCount": 1, "MinCount": 1
    }

    # Act
    response = ec2.run_instances(**params)
    instance_id = response['Instances'][0]['InstanceId']

    # Assert
    waiter = ec2.get_waiter('instance_running')
    waiter.wait(InstanceIds=[instance_id])

    # Cleanup
    ec2.terminate_instances(InstanceIds=[instance_id])
