Difficulty: MediumAWS Pricing Models

A smart agriculture company is deploying two distinct workloads on Amazon EC2. The first workload is a telemetry ingestion engine that runs continuously throughout the year with a highly predictable baseline resource utilization. The second workload is a periodic, non-critical data analysis job that can be interrupted and resumed at any time without affecting the application's integrity. Which two Amazon EC2 pricing models should the company select to achieve the most cost-effective solution? (Select TWO).

  1. Savings Plans for the telemetry ingestion engineAnswer
  2. Spot Instances for the periodic data analysis jobAnswer
  3. C
    On-Demand Instances for both workloads to maximize flexibility
  4. D
    Dedicated Hosts for the telemetry ingestion engine to ensure physical isolation
  5. E
    Spot Instances for the telemetry ingestion engine to reduce baseline costs

Answer

Savings Plans for the telemetry ingestion engine and Spot Instances for the periodic data analysis job.
Savings Plans provide substantial discounts (up to 72%) compared to On-Demand pricing in exchange for a commitment to a consistent amount of compute usage, making them ideal for the continuous, predictable telemetry workload. Spot Instances leverage spare AWS capacity to offer discounts up to 90%, which is perfect for non-critical, interruptible data analysis jobs.

Step-by-Step Solution

1
Analyze the resource utilization and runtime requirements of the telemetry ingestion workload.
The workload runs continuously and has a predictable baseline throughout the year.
Continuous, predictable workloads benefit from commitment-based discounts like Savings Plans or Reserved Instances rather than paying full On-Demand prices.
2
Analyze the tolerance for interruption and flexibility of the data analysis workload.
The job is periodic, non-critical, and can tolerate interruptions without data integrity issues.
Workloads that are highly flexible and interruptible are perfect candidates for Spot Instances, which provide the largest discount tier in EC2.
