Zorluk: KolayAWS Pricing Models

A media company needs to run a daily video transcoding job that processes user uploads. The workload is stateless, can be interrupted at any time without data loss, and does not have a strict completion deadline. Which Amazon EC2 pricing model is the most cost-effective choice for this workload?

  1. Spot InstancesCevap
  2. B
    On-Demand Instances
  3. C
    Reserved Instances
  4. D
    Dedicated Hosts

Cevap

Spot Instances
Spot Instances are the most cost-effective choice for this workload because they offer up to a 90% discount compared to On-Demand prices by utilizing unused AWS capacity. Because the transcoding job is stateless and has no strict completion deadline, it can easily tolerate the interruptions that may occur when AWS reclaims the capacity.

Adım Adım Çözüm

1
Identify key characteristics of the workload from the scenario: it is daily, stateless, interruptible, and has no strict deadline.
The workload is classified as fault-tolerant and flexible.
This classification allows us to filter out pricing models that charge a premium for uninterrupted service.
2
Compare the requirements against AWS EC2 pricing models to find the lowest-cost option that supports interruptions.
Spot Instances match the requirements and offer the lowest cost.
Spot Instances leverage unused EC2 capacity at significant discounts in exchange for the possibility of being reclaimed by AWS with a two-minute warning.
