A customer complaining the application has been slow or crashing.
What it does
With better database, it can solve the problem.
How I built it
Using AWS Aurora instead creating another MySQL Read Replica.
Challenges I ran into
-To overcome compatibility issues, I need to do mysqldump then upload the files into S3. -Creating MySQL replication is not as copy and paste a script. It took my weekends to make the replication works. -Recording my own voice need confidence and a quit room.
