Right sizing compute
An important question that arises is “do I first need to right-size my instances before reserving them?” Indeed, we don’t want to reserve an instance when it turns out it wasn’t the right instance to reserve in the first place! Doing so would contribute to waste. With SPs, this question becomes less relevant because with Compute SPs, you have more flexibility in the type of instances you launch. Even if you’re launching one instance type today, and you launch a different instance type tomorrow, you still benefit from the SP rate on the new instance type as long as you have enough in your cumulative hourly commitment to cover usage.
Right sizing is still a critical component of cloud waste management. Right sizing leverages the elasticity of the cloud. When you provisioned servers in a data center, you provisioned for peak. To maintain your service, you purchased enough servers (and beefy servers at that) to handle maximum capacity...
