Famiglie Instance Types

General Purpose (m5, m6)

Equilibrato tra CPU, memoria, rete.

# m5.large - 2 vCPUs, 8 GB
cpus: '2'
memory: 8G

Use case: Web server, application server

Burstable (t2, t3)

Credit-based CPU, basso costo.

# t2.micro - 1 vCPU, 1 GB
cpus: '1'
memory: 1G

Use case: Dev, test, microservizi

Compute Optimized (c5, c6)

Alto ratio CPU/memoria.

# c5.xlarge - 4 vCPUs, 8 GB
cpus: '4'
memory: 8G

Use case: Batch processing, encoding

Memory Optimized (r5, r6)

Alto ratio memoria/CPU.

# r5.large - 2 vCPUs, 16 GB
cpus: '2'
memory: 16G

Use case: Database, caching

  image: alpine:3.19
  deploy:
    resources:
      limits:
        cpus: '0.5'
        memory: 512M

T2 Micro (Dev/Test)

dev:
  image: node:alpine
  deploy:
    resources:
      limits:
        cpus: '1'
        memory: 1G

T2 Small (Web)

web:
  image: nginx:alpine
  deploy:
    resources:
      limits:
        cpus: '1'
        memory: 2G

T2 Medium (Application)

app:
  image: python:alpine
  deploy:
    resources:
      limits:
        cpus: '2'
        memory: 4G

M5 Large (Production)

production:
  image: nginx:alpine
  deploy:
    resources:
      limits:
        cpus: '2'
        memory: 8G
