Which EC2 instance option is suitable for tasks that do not require long-term commitment?

Spot Instances
Reserved Instances
On-Demand Instances
Dedicated Hosts

The correct answer is: On-Demand Instances

On-Demand Instances are a suitable option for tasks that do not require long-term commitment because they allow users to pay for compute capacity by the hour or second (depending on which operating system you use) with no long-term contracts or upfront payments. This flexibility makes On-Demand Instances ideal for applications with unpredictable workloads or varying computing needs. Users can easily start or stop instances as necessary, making it easy to scale resources up or down as requirements change. This model is particularly beneficial for short-term projects or applications in development and testing phases, where usage can fluctuate frequently, and there is no guarantee of consistent demand for resources. In contrast, other options such as Reserved Instances require a commitment to use EC2 capacity for a one- or three-year term, and Spot Instances involve bidding on spare Amazon EC2 capacity, which may not be suitable for urgent tasks. Dedicated Hosts provide physical servers dedicated to a single customer, which is a commitment that goes beyond mere instance purchasing.
