```### Exemplo de Automação

## Melhores Práticas

### Segurança
- Sempre verifique as somas de verificação ao baixar binários
- Use métodos de autenticação fortes (chaves de API, certificados)
- Atualize regularmente para a versão mais recente
- Siga o princípio do menor privilégio
- Ative o registro de auditoria para conformidade
- Use conexões criptografadas sempre que possível
- Valide todas as entradas e configurações
- Implemente controles de acesso adequados

### Desempenho
- Use limites de recursos apropriados para seu ambiente
- Monitore o desempenho do sistema regularmente
- Otimize a configuração para seu caso de uso
- Use processamento paralelo quando benéfico
- Implemente estratégias de cache adequadas
- Faça manutenção e limpeza regulares
- Identifique gargalos de desempenho
- Use algoritmos e estruturas de dados eficientes

### Operacional
- Mantenha documentação abrangente
- Implemente estratégias de backup adequadas
- Use controle de versão para configurações
- Monitore e alerte sobre métricas críticas
- Implemente tratamento de erros adequado
- Use automação para tarefas repetitivas
- Realize auditorias de segurança e atualizações regulares
- Planeje a recuperação de desastres

### Desenvolvimento
- Siga padrões e convenções de codificação
- Escreva testes abrangentes
- Use integração/implantação contínua
- Implemente registro e monitoramento adequados
- Documente APIs e interfaces
- Use controle de versão efetivamente
- Revise o código regularmente
- Mantenha compatibilidade com versões anteriores
