Zorluk: ZorAWS Database Services

A logistics company is designing a package tracking system to monitor real-time location telemetry from a fleet of delivery vehicles. The telemetry data consists of rapid, high-volume key-value writes that require single-digit millisecond latency at any scale. Concurrently, the company's data analysts need to perform complex SQL queries on petabytes of historical delivery data to optimize routes. Which two AWS database services should the company choose to meet these requirements?

  2. Amazon RedshiftCevap
  3. C
    Amazon RDS for PostgreSQL
  4. D
    Amazon ElastiCache
  5. E
    Amazon DocumentDB

Cevap

Amazon DynamoDB and Amazon Redshift
The correct services are Amazon DynamoDB and Amazon Redshift. Amazon DynamoDB provides the required single-digit millisecond latency for high-volume key-value telemetry data. Amazon Redshift is designed specifically for running complex analytical SQL queries against petabytes of historical structured data.

Adım Adım Çözüm

1
Analyze the real-time telemetry requirement
Identify that the telemetry data requires high-volume key-value writes and consistent, single-digit millisecond latency at any scale.
This workload profile maps directly to Amazon DynamoDB, which is optimized for high-throughput, low-latency NoSQL key-value use cases.
2
Analyze the historical analysis requirement
Identify that the data analysts require complex SQL queries on petabytes of historical shipping logs.
This analytical, large-scale SQL workload maps directly to Amazon Redshift, which is AWS's dedicated cloud data warehousing service designed for petabyte-scale analytics.
3
Evaluate and eliminate distractors
Eliminate options that fail to meet these requirements or violate AWS design principles.
Amazon RDS is not optimized for petabyte-scale data warehousing or extreme key-value writes. Amazon ElastiCache is an in-memory cache, not a persistent store. Amazon DocumentDB is a document store, not suited for the required telemetry performance or petabyte-scale SQL analytics.
