## Cloud Architecture Patterns
### High Availability Architecture
```hcl
# IaC: Multi-AZ deployment
resource "aws_instance" "app" {
count = 3
ami = var.app_ami
instance_type = "t3.medium"
availability_zone = element(var.azs, count.index)
tags = {
Name = "app-${count.index}"
Environment = var.environment
}
}
resource "aws_lb" "app" {
name = "app-lb"
load_balancer_type = "application"
subnets = aws_subnet.public[*].id
security_groups = [aws_security_group.lb.id]
}
resource "aws_lb_target_group" "app" {
name = "app-tg"
port = 8080
protocol = "HTTP"
vpc_id = aws_vpc.main.id
health_check {
path = "/health"
interval = 30
timeout = 5
healthy_threshold = 2
unhealthy_threshold = 2
}
}
```
### Auto-Scaling Configuration
```hcl
# Auto Scaling Group
resource "aws_autoscaling_group" "app" {
name = "app-asg"
vpc_zone_identifier = aws_subnet.private[*].id
target_group_arns = [aws_lb_target_group.app.arn]
min_size = 2
max_size = 10
desired_capacity = 2
launch_template {
id = aws_launch_template.app.id
version = "$Latest"
}
tag {
key = "Name"
value = "app-instance"
propagate_at_launch = true
}
}
# CPU-based scaling
resource "aws_autoscaling_policy" "cpu" {
name = "cpu-scaling"
autoscaling_group_name = aws_autoscaling_group.app.name
policy_type = "TargetTrackingScaling"
target_tracking_configuration {
predefined_metric_specification {
predefined_metric_type = "ASGAverageCPUUtilization"
}
target_value = 60.0
}
}
# Request count scaling
resource "aws_autoscaling_policy" "requests" {
name = "request-scaling"
autoscaling_group_name = aws_autoscaling_group.app.name
policy_type = "TargetTrackingScaling"
target_tracking_configuration {
predefined_metric_specification {
predefined_metric_type = "ALBRequestCountPerTarget"
}
target_value = 1000.0
}
}
```
### Serverless Architecture
```hcl
# Lambda function with API Gateway
resource "aws_lambda_function" "api" {
filename = "lambda.zip"
function_name = "api-handler"
role = aws_iam_role.lambda.arn
handler = "index.handler"
runtime = "nodejs18.x"
environment {
variables = {
TABLE_NAME = aws_dynamodb_table.data.name
}
}
}
resource "aws_apigatewayv2_api" "api" {
name = "api-gateway"
protocol_type = "HTTP"
}
resource "aws_apigatewayv2_integration" "lambda" {
api_id = aws_apigatewayv2_api.api.id
integration_type = "AWS_PROXY"
integration_uri = aws_lambda_function.api.invoke_arn
integration_method = "POST"
}
```
## Cost Optimization Strategies
### Right-Sizing Resources
```bash
# AWS: Analyze CloudWatch metrics for right-sizing
aws cloudwatch get-metric-statistics \
--namespace AWS/EC2 \
--metric-name CPUUtilization \
--dimensions Name=InstanceId,Value=i-1234567890abcdef0 \
--start-time 2024-01-01T00:00:00Z \
--end-time 2024-01-31T23:59:59Z \
--period 86400 \
--statistics Average
# Get cost recommendations
aws ce get-rightsizing-recommendation \
--service AmazonEC2
```
### Reserved Instances and Savings Plans
```hcl
# Cost optimization with reserved instances
# Analyze 30-day usage patterns first
data "aws_ec2_instance_type_offerings" "available" {
filter {
name = "instance-type"
values = ["t3.medium", "t3.large"]
}
}
# Document RI purchase recommendations
# 1-year no-upfront for flexibility
# 3-year all-upfront for maximum savings
```
### Spot Instances for Batch Workloads
```hcl
resource "aws_launch_template" "batch" {
name_prefix = "batch-"
instance_type = "c5.large"
instance_market_options {
market_type = "spot"
spot_options {
max_price = "0.05"
spot_instance_type = "one-time"
}
}
}
```
## Security Best Practices
### IAM Least Privilege
```hcl
# Principle of least privilege
data "aws_iam_policy_document" "app" {
statement {
actions = [
"s3:GetObject",
"s3:PutObject"
]
resources = [
"${aws_s3_bucket.data.arn}/*"
]
}
statement {
actions = [
"dynamodb:GetItem",
"dynamodb:PutItem",
"dynamodb:Query"
]
resources = [
aws_dynamodb_table.data.arn
]
}
}
resource "aws_iam_role_policy" "app" {
name = "app-policy"
role = aws_iam_role.app.id
policy = data.aws_iam_policy_document.app.json
}
```
### Network Security
```hcl
# Security groups with minimal access
resource "aws_security_group" "app" {
name = "app-sg"
description = "Application security group"
vpc_id = aws_vpc.main.id
ingress {
from_port = 8080
to_port = 8080
protocol = "tcp"
security_groups = [aws_security_group.lb.id]
description = "Allow from load balancer only"
}
egress {
from_port = 443
to_port = 443
protocol = "tcp"
cidr_blocks = ["0.0.0.0/0"]
description = "HTTPS to internet"
}
}
# Network ACLs for additional layer
resource "aws_network_acl" "private" {
vpc_id = aws_vpc.main.id
subnet_ids = aws_subnet.private[*].id
ingress {
rule_no = 100
protocol = "tcp"
action = "allow"
cidr_block = var.vpc_cidr
from_port = 0
to_port = 65535
}
}
```
## Monitoring and Alerting
```hcl
# CloudWatch alarms
resource "aws_cloudwatch_metric_alarm" "cpu_high" {
alarm_name = "cpu-utilization-high"
comparison_operator = "GreaterThanThreshold"
evaluation_periods = "2"
metric_name = "CPUUtilization"
namespace = "AWS/EC2"
period = "300"
statistic = "Average"
threshold = "80"
alarm_description = "CPU utilization is too high"
alarm_actions = [aws_sns_topic.alerts.arn]
dimensions = {
AutoScalingGroupName = aws_autoscaling_group.app.name
}
}
resource "aws_cloudwatch_metric_alarm" "cost_anomaly" {
alarm_name = "cost-anomaly-detected"
comparison_operator = "GreaterThanThreshold"
evaluation_periods = "1"
metric_name = "EstimatedCharges"
namespace = "AWS/Billing"
period = "86400"
statistic = "Maximum"
threshold = var.daily_cost_threshold
alarm_description = "Daily cost exceeds threshold"
alarm_actions = [aws_sns_topic.billing_alerts.arn]
}
```

- **Monitor Continuously**: Metrics, logs, traces, cost tracking
### Success Metrics
- **Availability**: >99.9% uptime for production services
- **Cost Efficiency**: Within 10% of budget, optimized resource utilization
- **Deployment Speed**: IaC deployments <15 minutes
- **Recovery Time**: RTO <1 hour, RPO <15 minutes
