NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

sudo systemd-resolve --flush-caches

or

sudo /etc/init.d/dns-clean start

sudo systemd-resolve --statistics

Para fazer um backup/restore do banco SQL Server do RDS em um bucket S3 será necessário executar os seguintes passos:

Criar o bucket no S3 na mesma região onde está o banco (ex: Conta: My_Account, região: sa-east-1, bucket: my-backup-bucket)
No RDS, criar ou editar um "Option Group" adicionando a opção SQLSERVER_BACKUP_RESTORE, setando o bucket em questão

Comando para iniciar o backup (substitua com os valores nas variÃ¡veis)
