Working with Lightsail Instances

Instance basics

Lightsail instances are virtual private servers that form the foundation of your application infrastructure. Each instance comes with dedicated compute resources, memory, and storage capacity.

Types of instances available

Lightsail offers a range of instance configurations to match different workload requirements:

Note: Specifications are current as of May 2025 but may change. Check the AWS Lightsail console for the most up-to-date information.

Operating system options

Lightsail supports multiple operating systems:

• Amazon Linux 2
• Ubuntu (20.04 LTS, 22.04 LTS)
• Debian (10, 11)
• Windows Server (2019, 2022)

SSH access and management

Secure instance access is provided through:

• Browser-based SSH console
• SSH key pair authentication
• Custom key management
• Terminal-based SSH access

Example: Connect to Lightsail instance using AWS CLI

# Get instance information
aws lightsail get-instance --instance-name MyLightsailInstance

# Download default SSH key
aws lightsail download-default-key-pair --output text --query privateKeyBase64
chmod 400 lightsail_key.pem

# Connect to instance
ssh -i lightsail_key.pem username@public-ip-address

RDP access for Windows

Lightsail Windows instances use Remote Desktop Protocol (RDP) for secure remote access:

• Browser-based RDP client
  • Access directly from Lightsail console
  • No additional software required
  • Supports clipboard sharing
  • Session timeout after 60 minutes of inactivity
• Using RDP client software
  • Download and use the RDP file from Lightsail console
  • Compatible with Microsoft Remote Desktop client
  • Available for Windows, macOS, iOS, and Android
  • Supports full-screen mode and peripheral redirection
• Authentication methods
  • Default administrator password (retrieved from console)
  • Custom password (set during instance creation)
  • Key-based authentication (when enabled)

Example: Connect to Windows instance using RDP client

1. From the Lightsail console, select your Windows instance
2. Click “Connect” and choose “Download RDP file”
3. Open the downloaded file with your RDP client
4. Retrieve the default password from the console
5. Enter the password when prompted by the RDP client

Example: Setting a custom password using AWS CLI

# Get the current password
aws lightsail get-instance-access-details --instance-name MyWindowsInstance

# Set a new password (user must be 'Administrator')
aws lightsail create-instance-access-key --instance-name MyWindowsInstance --protocol rdp --username Administrator

Security best practices for RDP access:

• Change the default administrator password immediately
• Use complex passwords (12+ characters with mixed case, numbers, symbols)
• Consider enabling password rotation policies
• Limit RDP access using instance firewall rules
• Monitor failed login attempts for suspicious activity
• Disconnect RDP sessions when not actively using the instance

Configuration Options

Lightsail instances offer various configuration options to tailor your environment to specific application needs. These options can be set during instance creation or modified afterward.

Storage Management

Lightsail provides flexible storage options to accommodate different application requirements:

• Primary Storage: Each instance includes built-in SSD storage that varies by plan (20GB to 640GB)
• Additional Block Storage: Expand capacity with attachable block volumes
  • Available in sizes from 8GB to 16TB
  • Independent lifecycle from instances
  • Can be attached/detached without instance restart
  • Ideal for database files, media libraries, and application data
• Snapshot Management: Create point-in-time backups of instances and disks
  • Automated or manual snapshot creation
  • Incremental storage to reduce costs
  • Rapid recovery during failures
  • Template for new instance deployment

Example: Creating and managing block storage with AWS CLI

# Create a new block storage disk
aws lightsail create-disk --disk-name MyDataDisk --availability-zone us-west-2a --size-in-gb 100

# Attach disk to instance
aws lightsail attach-disk --disk-name MyDataDisk --instance-name MyLightsailInstance --disk-path /dev/xvdf

# Format and mount the disk on Linux
ssh -i lightsail_key.pem username@your-instance-ip
sudo mkfs -t ext4 /dev/xvdf
sudo mkdir /mnt/data
sudo mount /dev/xvdf /mnt/data

Storage Performance Considerations:

• Primary instance storage performs best for OS and application files
• Block storage volumes provide consistent I/O performance
• For high I/O workloads, consider using multiple volumes
• Benchmark your specific workload to determine optimal configuration

Static IP Allocation

By default, Lightsail instances receive a dynamic public IP address that changes when the instance is stopped and started. Static IPs provide consistent addressing:

• Benefits of Static IPs:
  • Consistent DNS record mapping
  • Simplified firewall configurations
  • Improved reliability for long-running services
  • No downtime during instance replacement
  • Seamless transition during scaling operations
• Management Features:
  • One-click allocation through console
  • Easy attachment to any instance in the same region
  • Retention when instances are terminated
  • Transfer between instances without DNS changes
  • No additional cost when attached to running instances

Example: Static IP lifecycle management with AWS CLI

# Allocate a new static IP
aws lightsail allocate-static-ip --static-ip-name MyProductionIP

# Attach to an instance
aws lightsail attach-static-ip --static-ip-name MyProductionIP --instance-name MyWebServer

# View static IP details
aws lightsail get-static-ip --static-ip-name MyProductionIP

# Detach from current instance (before attaching to another)
aws lightsail detach-static-ip --static-ip-name MyProductionIP

# Release the static IP when no longer needed
aws lightsail release-static-ip --static-ip-name MyProductionIP

Best Practices for Static IPs:

• Allocate static IPs for all production services
• Use descriptive names that reflect the service purpose
• Document IP assignments in your infrastructure inventory
• Consider DNS names for user-facing services rather than direct IP access
• Implement proper security controls as static IPs are publicly accessible

Firewall Rules and Security

Lightsail includes a built-in firewall that controls inbound traffic to your instances:

• Rule-Based Protection:
  • Fine-grained control over inbound connections
  • Protocol-specific rules (TCP, UDP, ICMP)
  • Port range configuration for service access
  • Source IP restrictions for enhanced security
  • Default deny-all with explicit allow rules
• Common Configurations:
  • Web servers: HTTP (80), HTTPS (443)
  • SSH access: TCP port 22
  • Application-specific ports (e.g., 3000 for Node.js)
  • Database access ports (MySQL: 3306, PostgreSQL: 5432)
  • Custom application requirements

Example: Comprehensive firewall configuration with AWS CLI

# Allow HTTPS traffic
aws lightsail open-instance-public-ports \
  --port-info fromPort=443,toPort=443,protocol=TCP \
  --instance-name MyWebServer

# Allow SSH from specific IP address only
aws lightsail open-instance-public-ports \
  --port-info fromPort=22,toPort=22,protocol=TCP,cidrs=203.0.113.25/32 \
  --instance-name MyWebServer

# Allow custom application port
aws lightsail open-instance-public-ports \
  --port-info fromPort=8080,toPort=8080,protocol=TCP \
  --instance-name MyWebServer

# View current firewall configuration
aws lightsail get-instance-port-states --instance-name MyWebServer

# Close a previously opened port
aws lightsail close-instance-public-ports \
  --port-info fromPort=8080,toPort=8080,protocol=TCP \
  --instance-name MyWebServer

Security Best Practices:

• Follow the principle of least privilege – open only necessary ports
• Restrict SSH access to specific IP addresses when possible
• Use HTTPS for all web traffic with proper SSL/TLS certificates
• Regularly audit your firewall rules and remove unused permissions
• Implement application-level security in addition to network controls
• Consider using a bastion host for accessing internal instances

Load Balancing in Lightsail

Understanding Lightsail Load Balancers

Load balancers are essential components for distributing traffic across multiple instances, ensuring high availability and improved performance for your applications. Lightsail’s load balancing service provides a cost-effective way to implement this critical infrastructure component.

Key Features and Capabilities

• Traffic Distribution: Automatically routes incoming traffic across multiple healthy instances
• Health Monitoring: Continuously checks instance health and routes traffic only to healthy instances
• Session Persistence: Maintains user sessions on the same instance for stateful applications
• TLS/SSL Termination: Handles HTTPS encryption/decryption to reduce instance processing load
• Multiple Availability Zone Support: Distributes instances across different zones for fault tolerance

Traffic Distribution Methods

Lightsail load balancers use several techniques to optimize traffic handling:

• Round-Robin Distribution: Evenly distributes requests across all healthy instances
• Session-Based Routing: Directs requests from the same client to the same instance using cookies
• Health-Based Routing: Automatically diverts traffic from unhealthy instances
• Protocol Support: Handles both HTTP and HTTPS traffic with configurable ports

Implementation and Configuration

Setting Up Load Balancers

Follow these steps to implement a load balancer for your application:

1. Create a new load balancer:
   • Navigate to the Lightsail console and select the “Networking” tab
   • Click “Create load balancer” and enter a name
   • Select the AWS Region where your instances are located
   • Choose HTTP or HTTPS (or both) and specify ports
2. Define target instances:
   • Select instances to receive traffic from the load balancer
   • Instances must be in the same AWS Region as the load balancer
   • Instances can be in different Availability Zones for high availability
   • Verify instance security group allows traffic from the load balancer
3. Configure networking rules:
   • Set instance ports that will receive traffic from the load balancer
   • Configure SSL if using HTTPS (upload or create certificate)
   • Set session persistence options if needed
   • Configure health check parameters
4. Configure distribution parameters:
   • Select session stickiness options if required
   • Set cookie duration for session persistence
   • Configure idle connection timeout
   • Set up path-based routing if needed
5. Enable health monitoring:
   • Define health check path (e.g., /health or /status)
   • Set health check interval (5-300 seconds)
   • Configure health threshold count (2-10 consecutive successes)
   • Set unhealthy threshold count (2-10 consecutive failures)
   • Define timeout period (2-60 seconds)

Example: Creating a complete load balancer configuration using AWS CLI

# Step 1: Create the load balancer
aws lightsail create-load-balancer \
  --load-balancer-name MyProductionLB \
  --instance-port 80 \
  --health-check-path /health \
  --health-check-delay-seconds 10 \
  --health-check-timeout-seconds 5 \
  --health-check-threshold-count 3 \
  --unhealthy-threshold-count 3 \
  --session-stickiness-enabled \
  --session-stickiness-lb-cookie-duration-seconds 86400

# Step 2: Attach instances to the load balancer
aws lightsail attach-instances-to-load-balancer \
  --load-balancer-name MyProductionLB \
  --instance-names MyWebServer1 MyWebServer2 MyWebServer3

# Step 3: Create and attach an SSL/TLS certificate
aws lightsail create-load-balancer-tls-certificate \
  --load-balancer-name MyProductionLB \
  --certificate-name MySSLCert \
  --certificate-domain-name example.com \
  --certificate-alternative-names www.example.com

# Step 4: Enable HTTPS on the load balancer
aws lightsail update-load-balancer-attribute \
  --load-balancer-name MyProductionLB \
  --attribute-name HttpsRedirectionEnabled \
  --attribute-value true

Health Check Configuration

Health checks are critical for maintaining high availability. Configure them properly to ensure accurate instance health assessment:

• Custom health check paths: Create dedicated endpoints that verify application health
  • Simple path: /health or /ping that returns HTTP 200
  • Comprehensive check: Verify database connectivity, cache access, and API dependencies
  • Stateless check: Should not require authentication or session state
• Response timeout settings:
  • Set appropriate timeout values based on expected response time
  • Shorter timeouts (2-5 seconds) for quick responses
  • Longer timeouts for complex health checks (up to 60 seconds)
• Health check intervals:
  • Balance between responsiveness and resource consumption
  • Shorter intervals (5-15 seconds) for critical applications
  • Longer intervals (30-60 seconds) for stable, non-critical workloads
• Threshold configurations:
  • Set healthy threshold count (consecutive successful checks to mark healthy)
  • Configure unhealthy threshold count (consecutive failed checks to mark unhealthy)
  • Avoid too low thresholds (prevent flapping) or too high (slow recovery)
• Automated instance removal/addition:
  • Instances automatically removed from rotation when unhealthy
  • Automatically returned to service when health is restored
  • Configure appropriate thresholds to prevent premature removal

SSL/TLS Certificate Integration

Secure your applications with HTTPS using Lightsail’s certificate management:

• Certificate management:
  • Create or upload SSL/TLS certificates directly in Lightsail
  • Automatic validation for domains managed in Route 53
  • Manual validation through DNS records or email verification
  • Support for wildcard certificates (*.example.com)
• Domain validation:
  • DNS validation: Add CNAME records to your domain
  • Email validation: Respond to verification emails
  • Validation must be completed within 72 hours
  • Multiple validation methods available for flexibility
• Automatic renewal options:
  • Lightsail-issued certificates renew automatically if validation records remain
  • Renewal begins 60 days before expiration
  • Email notifications for renewal status
  • Manual intervention required if validation method changes
• Custom certificate upload:
  • Import certificates from third-party certificate authorities
  • Support for multiple certificate formats
  • Certificate chain must be complete and valid
  • Private key must match the certificate
• SSL policy configuration:
  • TLS protocol version selection
  • Cipher suite configuration
  • Security policy compliance
  • HTTPS redirection options

Example: Setting up a complete HTTPS configuration

# Create certificate
aws lightsail create-load-balancer-tls-certificate \
  --load-balancer-name MyLoadBalancer \
  --certificate-name MyProductionCert \
  --certificate-domain-name example.com

# Check validation status
aws lightsail get-load-balancer-tls-certificates \
  --load-balancer-name MyLoadBalancer

# Enable HTTPS and redirect HTTP to HTTPS
aws lightsail update-load-balancer-attribute \
  --load-balancer-name MyLoadBalancer \
  --attribute-name HttpsRedirectionEnabled \
  --attribute-value true

# Start CloudWatch agent
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a fetch-config -m ec2 -s -c file:/opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.json

# Verify agent is running
sudo /opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -m ec2 -a status

Custom Metric Creation

While Lightsail provides essential metrics out of the box, you can extend monitoring with custom metrics:

Example: Custom metric script for WordPress user registrations

#!/bin/bash
# Save as /etc/cron.hourly/wp-metrics.sh and make executable

# Connect to WordPress database and count new users in past hour
NEW_USERS=$(mysql -h wordpress-db.example.com -u dbuser -p'dbpassword' wordpress -e "
  SELECT COUNT(*) 
  FROM wp_users 
  WHERE user_registered >= DATE_SUB(NOW(), INTERVAL 1 HOUR);" | tail -1)

# Put custom metric to CloudWatch
aws cloudwatch put-metric-data \
  --namespace "WordPress/UserMetrics" \
  --metric-name "NewUserRegistrations" \
  --value $NEW_USERS \
  --unit "Count" \
  --dimensions Site=MyWordPressSite

# Log for reference
echo "$(date): Reported $NEW_USERS new user registrations" >> /var/log/wp-metrics.log

Best Practices for Monitoring

• Set up comprehensive monitoring from day one
• Monitor both infrastructure and application metrics
• Establish baseline performance metrics
• Create actionable alerts with clear thresholds
• Implement log rotation and management
• Automate routine maintenance tasks
• Review and analyze performance trends regularly
• Document monitoring procedures and escalation processes
• Test alerting systems periodically
• Maintain historical performance data for capacity planning

   • Large ($20/mo): Business sites with e-commerce or higher traffic
   • Consider future growth needs when selecting a plan
3. Configure instance location:
   • Choose a region close to your target audience
   • Select an availability zone (or use the default)
4. Set instance name and tags:
   • Use descriptive names (e.g., “company-wordpress-production”)
   • Add tags for organization (e.g., “environment:production”)

Example: Creating WordPress instance with AWS CLI

aws lightsail create-instances \
  --instance-names MyWordPressSite \
  --availability-zone us-west-2a \
  --blueprint-id wordpress \
  --bundle-id medium_3_0 \
  --tags key=environment,value=production

WordPress Configuration

Initial Access and Security

1. Get WordPress admin password:
   • Connect to your instance via browser-based SSH
   • Run cat $HOME/bitnami_application_password to get the default password
   • Note this password for the initial WordPress login
2. Configure the basic security settings:
   • Change the default Bitnami account password
   • Update the WordPress admin password to a strong alternative
   • Configure automatic WordPress core updates
3. Set up WordPress site information:
   • Log in to WordPress admin (https://your-instance-ip/wp-admin)
   • Navigate to Settings → General
   • Set site title, tagline, and time zone
   • Configure permalink structure (Settings → Permalinks)

Domain Configuration

1. Allocate a static IP:
   • From the Lightsail console, go to the Networking tab
   • Create and attach a static IP to your WordPress instance
   • Note the static IP for DNS configuration
2. Configure DNS settings:
   • Option 1: Use Lightsail DNS zone
     • Create a DNS zone in Lightsail
     • Add A records pointing to your static IP
     • Update domain registrar with Lightsail nameservers
   • Option 2: Use external DNS provider
     • Create an A record pointing to your static IP
     • Add www CNAME record if needed
3. Update WordPress site URL:
   • In WordPress admin, go to Settings → General
   • Update WordPress Address and Site Address with your domain
   • Save changes and verify site access through the domain

Example: Setting up DNS in Lightsail using AWS CLI

# Create a DNS zone
aws lightsail create-domain --domain-name example.com

# Create A record for root domain
aws lightsail create-domain-entry \
  --domain-name example.com \
  --domain-entry "{\"name\":\"@\",\"type\":\"A\",\"target\":\"192.0.2.123\"}"

# Create CNAME for www
aws lightsail create-domain-entry \
  --domain-name example.com \
  --domain-entry "{\"name\":\"www\",\"type\":\"CNAME\",\"target\":\"example.com\"}"

Security and SSL Setup

1. Set up SSL certificate:
   • Option 1: Using Bitnami HTTPS configuration toolsudo /opt/bitnami/bncert-tool
     • Follow the prompts to configure your domain and obtain a Let’s Encrypt certificate
   • Option 2: Manual Let’s Encrypt setupsudo apt update sudo apt install certbot python3-certbot-apache -y sudo certbot --apache -d example.com -d www.example.com
2. Force HTTPS redirect:
   • Verify SSL is working by accessing https://yourdomain.com
   • Check that HTTP automatically redirects to HTTPS
   • If not configured, modify .htaccess or Apache configuration
3. Implement security best practices:
