Why Use Reserved Instances?
Financial Pain Points of Subscription and PAYG Billing
1.Subscription instances require lump sum prepayments and exert heavy upfront financial pressure.
2.Pay-as-you-go prices are high and not suitable for long-term and stable computing needs.
O&M Pain Points of Subscription and PAYG Billing
1.For subscription instances, discounts are exclusive to specific computing resources, limiting flexibility.
2.For subscription instances, you have to implement lifecycle management on a per-instance basis, which results in a huge O&M workload.
3.Without resource reservations, you may have to wait when you attempt to create pay-as-you-go instances.
Reserved Instances Help You to
1.Reduce costs: Compared with pay-as-you-go instances, reserved instances provide you with significant discounts up to 79%.
2.Ease financial pressure: In addition to All Upfront, reserved instances provide the Partial Upfront and No Upfront payment options, which allow you to pay low or none upfront payments, reducing financial pressure.
3.Improve O&M efficiency: Reserved instances are used in combination with pay-as-you-go instances. You can modify the scopes of reserved instances across zones and use reserved instances to create or release matching pay-as-you-go instances as needed.
4.Simplify lifecycle management: One reserved instance can match multiple pay-as-you-go instances. After the reserve instance expires, the pay-as-you-go instances that you create by using this reserve instance are not released.
5.Reserve resources: Zonal reserved instances provide resource reservations.
6.Deliver compute power: Reserved instances enable the direct delivery of compute power, and completely decouple discounts from specific instances, and allow enterprises to build their internal compute power pools.
