Question
Which pricing model in AWS is best suited for workloads with predictable usage?a)On-Demand Instancesb)Reserved Instancesc)Spot Instancesd)None of the mentioned
Solution
The best suited pricing model in AWS for workloads with predictable usage is b) Reserved Instances.
Here's why:
-
On-Demand Instances: This model is best when you need low cost and flexibility without any up-front payment or long-term commitment. However, it can be more expensive for predictable workloads.
-
Reserved Instances: This model provides a significant discount (up to 75%) compared to On-Demand pricing and provide a capacity reservation when used in a specific Availability Zone. This makes it ideal for predictable workloads.
-
Spot Instances: This model allows you to bid on spare Amazon EC2 computing capacity. While it can be the cheapest option, it's also the most unpredictable because your instances can be terminated with short notice when Amazon needs the capacity back.
-
None of the mentioned: This is not a valid option as the question is specifically asking about AWS pricing models
