Hello wara,
Thanks for your feedback.
Yes, you’re right. Technically, your application will still be able to connect to your database during the change. But it comes at the expense of a decrease in read/write IOPS. Your DBs ability to serve requests depends on different factors like how large its capacity (instance size) is and its configuration settings.
There was this one time when I tried to increase the storage of an RDS database. I noticed a huge spike in CPU utilization during the change rendering my application unusable for a few minutes. I think this is what I was going for when I created this question. But, yeah, technically the database remains available during the change. We will make some wording adjustments to the scenario so that it’ll fit the narrative described in the documentation.
Let me know if this answers your question.
Thanks and Regards,
Carlo @ Tutorials Dojo
