Update AWS RDS Instance Type
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.
As the workload and performance requirements of an application change, there might be a need to adjust the compute capacity of the RDS instance. AWS provides the capability to modify the instance type of an RDS instance, offering flexibility in terms of performance and cost. By using this task users can seamlessly upgrade or downgrade the instance type, optimizing for their current needs. This modification, while straightforward, should be approached with caution to ensure minimal disruption to services relying on the database.
