Zorluk: OrtaAWS Pricing Models

An educational technology company is planning to deploy two distinct workloads on Amazon EC2:
1. A production student portal application that must run continuously 24/724/7 and exhibits stable, predictable usage throughout the school year.
2. A machine learning model training job that runs periodically, can be safely paused and resumed, and needs the absolute lowest cost compute options.

Which two Amazon EC2 pricing models should the company select to run these workloads in the most cost-effective manner?

  1. Reserved Instances for the continuous student portal applicationCevap
  2. Spot Instances for the periodic machine learning training jobCevap
  3. C
    On-Demand Instances for the continuous student portal application
  4. D
    Dedicated Hosts for the periodic machine learning training job
  5. E
    AWS Free Tier to run both workloads

Cevap

Reserved Instances for the continuous student portal application and Spot Instances for the periodic machine learning training job
For the continuous and predictable student portal application, Reserved Instances provide a significant discount (up to 72%72\%) in exchange for a one-year or three-year commitment. For the periodic and interruptible machine learning model training job, Spot Instances offer the lowest cost (up to a 90%90\% discount) because they utilize unused EC2 capacity and can be reclaimed by AWS with a two-minute warning.

Adım Adım Çözüm

1
Analyze the student portal application workload requirements.
The application requires constant 24/724/7 availability with a predictable load pattern.
Predictable, steady-state workloads benefit most from the significant discounts provided by Reserved Instances or Savings Plans in exchange for a commitment.
2
Analyze the machine learning model training workload requirements.
The training job is periodic, flexible, and can tolerate interruptions.
Spot Instances are the most cost-effective option for fault-tolerant, flexible workloads because they offer up to a 90%90\% discount compared to On-Demand rates.
