Zorluk: KolayUnderstand concepts of cloud economics

A local bookstore chain is migrating its inventory database and customer-facing web application from on-premises physical servers to the AWS Cloud. Which two of the following choices represent core cloud economics benefits of this migration?

  1. Replacing upfront capital expenses for hardware with variable operating expenses.Cevap
  2. Eliminating the need to estimate capacity needs by automatically scaling resources with customer demand.Cevap
  3. C
    Increasing capital expenses by prepaying for dedicated physical server ownership in AWS data centers.
  4. D
    Ensuring high performance by maintaining constant maximum capacity regardless of actual bookstore traffic.
  5. E
    Lowering operations cost by designing a tightly coupled monolithic infrastructure structure.

Cevap

Replacing upfront capital expenses for hardware with variable operating expenses, and eliminating the need to estimate capacity needs by automatically scaling resources with customer demand.
Replacing upfront capital expenses with variable operating expenses enables a pay-as-you-go financial model. Eliminating guess capacity requirements via elasticity optimizes cost by scaling down resources when they are not needed.

Adım Adım Çözüm

1
Analyze the financial implications of shifting from on-premises infrastructure to the cloud.
Identify that the shift reduces upfront physical hardware investments (CapEx) in favor of pay-as-you-go services (OpEx).
This is a fundamental concept of cloud economics where businesses pay only for what they use.
2
Analyze how elasticity affects infrastructure sizing and cost optimization.
Identify that dynamic scaling removes the risk of under-provisioning or over-provisioning (guessing capacity).
Elasticity allows resource supply to match demand closely, maximizing cost efficiency.
