A company needs a test environment for only a few weeks and wants to launch instances when needed and pay only for what is used, with no long-term commitment or upfront payment. Which Amazon EC2 purchasing option BEST meets these requirements?
A question asking to select the EC2 purchasing option for short-term, low-commitment use.
On-Demand Instances
This is correct. On-Demand Instances allow a company to pay by the second or hour for what is used, with no long-term commitment or upfront payment. They offer the greatest flexibility for short-term test environments and unpredictable workloads.
Reserved Instances
Reserved Instances provide discounts in exchange for a 1-year or 3-year long-term commitment.
This does not meet the requirement to avoid a long-term commitment for a few weeks of use. This is incorrect.
Savings Plans
Savings Plans provide discounts in exchange for committing to a consistent amount of usage for 1 or 3 years.
This does not meet the requirement to avoid a long-term commitment for short-term use. This is incorrect.
Dedicated Host
A Dedicated Host is a purchasing option that dedicates an entire physical server to a single customer, typically used for licensing or compliance requirements.
This does not meet the requirement for short-term, low-commitment test use. This is incorrect.
'No commitment,' 'pay only for usage,' and 'short-term or unpredictable' all point to On-Demand. For stable long-term workloads with discounts, use Reserved Instances or Savings Plans. For the lowest cost with interruptions allowed, use Spot Instances.
