A shipping company is migrating its legacy container tracking system to AWS. The system experiences high demand during the holiday season (300%300\% of baseline load), stable demand during the rest of the year, and requires a minimal baseline of 1010 servers running 24/724/7 for core operations. On-premises, the company pays for server hardware depreciation (fixed capital expenses), virtualization licenses, data center cooling, and physical security. The company aims to optimize its Total Cost of Ownership (TCO) and operational efficiency on AWS.

Which of the following actions align with the core principles of AWS cloud economics? (Select TWO.)

Cevap: Transitioning from physical server depreciation and upfront hypervisor licensing fees to AWS pay-as-you-go billing shifts fixed capital expenses (CapEx) to variable operating expenses (OpEx).; Applying Amazon EC2 Auto Scaling to dynamically provision instances to handle the seasonal holiday spikes and terminate them afterwards minimizes Total Cost of Ownership (TCO) by leveraging elasticity.

Cevap

Transitioning from physical server depreciation and upfront hypervisor licensing fees to AWS pay-as-you-go billing shifts fixed capital expenses (CapEx) to variable operating expenses (OpEx), and applying Amazon EC2 Auto Scaling to dynamically provision instances to handle the seasonal holiday spikes and terminate them afterwards minimizes Total Cost of Ownership (TCO) by leveraging elasticity.
The transition from physical server depreciation and licensing to pay-as-you-go billing is correct because it shifts capital expenses (CapEx) into operating expenses (OpEx), reducing upfront costs. The dynamic usage of Amazon EC2 Auto Scaling is correct because it utilizes elasticity to align resource supply with real-time demand, removing the financial burden of running idle servers during off-peak periods.

Adım Adım Çözüm

1
Identify the financial transition
On-premises costs (server depreciation and upfront virtualization hypervisor licenses) are Capital Expenses (CapEx). Migrating to AWS pay-as-you-go billing replaces these with variable Operating Expenses (OpEx).
Understanding CapEx vs. OpEx is the foundation of cloud economics.
2
Assess workload characteristics and apply elasticity
The holiday spikes represent a 300%300\% surge that is temporary. Applying Auto Scaling dynamically handles the spikes and terminates instances off-peak, minimizing idle resource costs.
Elasticity is the direct countermeasure to the cost of idle capacity.
3
Evaluate baseline requirements against EC2 pricing options
The baseline of 1010 servers requires 24/724/7 constant availability. Spot Instances are interruptible and unsuitable here, while Reserved Instances are best suited for this steady-state baseline, not the seasonal spikes.
Matching the correct pricing model to the workload profile prevents availability issues and cost inefficiencies.

Anahtar Kavram

Cloud economics relies on transitioning CapEx to OpEx, minimizing Total Cost of Ownership (TCO) through elasticity, and selecting the appropriate pricing models for different workload profiles.

Which two outcomes represent the primary cloud economics benefits of migrating this system to AWS? (Select TWO).

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Transitioning from upfront hardware investments to a variable operational expense model that aligns costs with passenger demand.; Reducing the total cost of ownership by dynamically matching infrastructure capacity with peak transit hours, eliminating the need to pay for idle resources during overnight periods.

Cevap

Transitioning from upfront hardware investments to a variable operational expense model that aligns costs with passenger demand, and reducing the total cost of ownership by dynamically matching capacity with peak transit hours.
The correct outcomes are transitioning to a variable operational expense model and reducing TCO via dynamic capacity matching. Transitioning to a variable operational expense model replaces large upfront capital expenditures (CapEx) on hardware with pay-as-you-go operating expenses (OpEx). Dynamically matching capacity with peak demand leverages elasticity, meaning resources scale up during peak passenger volumes and scale down during overnight hours, preventing costs from running on idle resources.

Adım Adım Çözüm

1
Analyze the financial transition described in the scenario, identifying the shift from buying physical mainframes to renting AWS resources.
Identify that the upfront hardware cost constitutes Capital Expenditure (CapEx), while paying for active resources constitutes Operating Expenditure (OpEx). Thus, transitioning to a variable operational expense model is correct.
Understanding the shift from CapEx to OpEx is fundamental to cloud economics.
2
Analyze the workload characteristics (extreme peak hours vs. low overnight usage) to evaluate capacity requirements.
Identify that the system has highly variable demand, meaning elasticity (scaling resources dynamically) will prevent pay-for-idle scenarios and reduce the total cost of ownership (TCO).
Elasticity is the core mechanism that optimizes costs for fluctuating workloads.

Analyze the workload characteristics
Two distinct workloads exist: a daily fluctuating IoT workload with morning/evening peaks, and an intermittent 24-hour monthly workload.
Different workload patterns require different cost-optimization strategies in cloud economics.
2
Evaluate the daily fluctuating workload strategy
Elasticity is the best approach. Dynamic scaling matches resource supply with demand, avoiding overprovisioning costs.
Auto Scaling allows the company to transition from a fixed capacity model to a variable pay-as-you-go model.
3
Evaluate the monthly 24-hour workload strategy
On-Demand or Spot Instances are best because they only incur costs for the 24 hours of execution, whereas Reserved Instances would charge for unused hours.
Reserved Instances are designed for continuous, steady-state workloads (high utilization), not intermittent tasks.

Cevap: Refactoring

Cevap

Refactoring
Refactoring (or Re-architecting) is the correct answer because PixelQuest Games is modifying the architecture by splitting a monolithic application into microservices and rewriting the code to utilize cloud-native, serverless components. This strategy is chosen to meet business requirements for scalability and cost-efficiency that cannot be achieved with the existing architecture.

Adım Adım Çözüm

1
Analyze the business requirements and the architectural changes being made to the matchmaking application.
The company is breaking a monolithic application into microservices and rewriting the code to run on serverless services like AWS Lambda and Amazon DynamoDB.
Identifying the scope of changes helps determine which of the 6 Rs migration strategies is being applied.
2
Map these changes to the defined AWS migration strategies.
Modifying, re-architecting, or rewriting code to use cloud-native features such as serverless technology is defined as Refactoring (also known as Re-architecting).
This differentiates Refactoring from other strategies that do not involve code or architectural changes.

A retail company, Nova Retail, is planning the migration of its legacy inventory database to the AWS Cloud. Currently, the database is hosted on-premises on a virtual machine, and the operations team spends substantial effort on operating system patching, backups, and storage provisioning. To reduce this administrative burden, Nova Retail decides to migrate the database to Amazon Relational Database Service (Amazon RDS) for Oracle, keeping the database engine and the application code unchanged. Which migration strategy is Nova Retail executing for this database?

Cevap: Replatforming

Cevap

Replatforming
The correct strategy is replatforming because the company is making a platform optimization—moving from a self-managed database to the fully managed Amazon RDS platform to reduce administrative tasks like patching and backups—while keeping the application code and database engine unchanged.

Adım Adım Çözüm

1
Analyze the migration target and changes being made.
The target is Amazon RDS for Oracle, and the core application code and database engine remain unchanged.
Identifying the scope of changes helps distinguish between Rehost (no changes/EC2), Replatform (managed services/RDS), and Refactor (code changes).
2
Determine the cloud service model shift.
The database is moving from a self-managed environment (on-premises VM) to a fully managed service (Amazon RDS).
Moving to a managed service to reduce administrative tasks (like patching and backups) without changing the core application structure constitutes a platform optimization (tinkering).
3
Map the optimization to the 6 Rs migration strategies.
Since optimization is achieved by switching the platform to Amazon RDS without modifying application code, this is classified as Replatforming.
This matches the definition of Replatforming, which focuses on shifting to managed services to gain cloud benefits without re-architecting.
