3. Nuvola
● > 2M active users
● > 1000 sql databases & > 500GB of relational data
● ~ 400M SQL queries / day (average)
● from few to ~ 200k sessions in 5 minutes at 8 a.m.
● 1M / week archived documents
Nuvola is a data-driven software

4. Relational data: how to?
● Handle very fast increasing growth
● Handle 400M sql queries / day
● High reliability
● Automatic backups
● Automatic os and db engine patches
● Scale based on traffic
● Continuously monitoring
● … add your own spec!

5. Old infrastructure
● 25 Mysql 5.6 instances
● Master - slave replication for high reliability: 50 instances
● Backups on slaves machines.
● Self-made monitoring and patching
It works but it’s fragile, error-prone and require a bunch of sysadmins
to keep it secure, up to date and working properly.
Tons of man hours ($$$)

6. AWS
...
is your
sysadmin

7. AWS RDS
● 12 MySQL 5.7 M4.large instances
● Multi AZ
● Rich API & Ansible as configuration management tool
● Automatic snapshots & backups
● Integrated monitoring and patching
● Easy to update (single click from to MySQL 5.6 to 5.7)

It took ~ 50 minutes!

10. AWS RDS
● Db infrastructure a lot more reliable and efficient
● Everything automated
● Saved tons of man hours ($$$ and sleep hours)
Current and future steps
● Auto-scaling to better fit consumptions to real needs
● Give Aurora a try and do some benchmarks vs RDS MySQL
