vertical scaling
Give one instance more CPU, memory, or I/O capacity.
Use this when One database instance is constrained by a measured resource bottleneck.
without the term
“Should we buy a larger database instance? Measure whether CPU, memory, or I/O is the actual limit.”
with the term · How do you ask a model for vertical scaling?
Evaluate vertical scaling for the measured bottleneck. Compare throughput, latency, cost, and resize downtime.
What is vertical scaling?
Vertical scaling increases the resources of an instance. It can postpone distribution work, but hardware ceilings, resize procedures, and single-instance failure exposure still matter.
Why does vertical scaling matter when vibe coding?
An agent can recommend a larger machine when the real delay is lock contention or a slow query.
How do you do vertical scaling?
Identify the constrained resource, compare a larger instance under the same workload, and check resizing downtime, cost, and remaining headroom.
What goes wrong with vertical scaling?
More CPU does not repair a serialized critical section, missing index, or remote dependency bottleneck.
