Zenith Commerce is planning to migrate its on-premises application portfolio to the AWS Cloud. The IT team has defined two specific goals for this migration phase:
1. Migrate their self-managed relational database to Amazon RDS for PostgreSQL to minimize database administration overhead, without changing the application's core logic.
2. Replace their legacy, self-managed customer relationship management (CRM) software with a cloud-native Software-as-a-Service (SaaS) solution.

Which of the following migration strategies should the company use to achieve these goals? (Select TWO.)

Select all that apply

Show answer & explanation

Answer: Replatforming to migrate the relational database to Amazon RDS; Repurchasing to transition the CRM software to a cloud-native SaaS solution

Answer

Replatforming should be used to migrate the database to Amazon RDS, and Repurchasing should be used to transition the CRM software to a SaaS solution.
The correct options are Replatforming and Repurchasing. Replatforming is correct for the database migration because it shifts the workload to a managed database service (Amazon RDS) to optimize operations without redesigning the application logic. Repurchasing is correct for the CRM system because the company is retiring its legacy, self-managed CRM software in favor of adopting a new cloud-native SaaS model.

Step-by-Step Solution

1
Analyze the first migration requirement: moving a self-managed relational database to a managed database service (Amazon RDS) to reduce administrative overhead without altering core logic.
Identify that this matches the Replatforming strategy. In a replatforming migration, core application code is not changed, but minor optimizations or component updates (like shifting to a managed service) are executed.
This strategy allows the organization to achieve cloud benefits like reduced administration without the risk and effort of a full code redesign.
2
Analyze the second migration requirement: replacing a legacy, self-managed CRM application with a cloud-native Software-as-a-Service (SaaS) solution.
Identify that this matches the Repurchasing strategy. Repurchasing involves abandoning the existing application and buying a new product, typically a SaaS version.
Replacing custom or legacy code with a SaaS platform represents a licensing model change and software replacement, which defines the repurchasing strategy.

A local dental clinic is migrating its patient scheduling system from an on-premises server room to the AWS Cloud. Instead of purchasing physical servers upfront, the clinic will now pay a variable monthly fee based on the resources they consume. Which of the following options describes this shift in financial expenditure?

Show answer & explanation

Answer: A shift from Capital Expenses (CapEx) to Operating Expenses (OpEx)

Answer

A shift from Capital Expenses (CapEx) to Operating Expenses (OpEx)
The correct answer describes a shift from Capital Expenses (CapEx) to Operating Expenses (OpEx). On-premises data centers require significant capital investment upfront to purchase physical servers and networking gear (CapEx). Moving to a cloud model like AWS allows organizations to pay only for what they use on a variable, recurring basis, which is classified as an operational expense (OpEx).

Step-by-Step Solution

1
Identify the financial model of the current state.
The clinic is purchasing physical servers upfront, which represents a capital expenditure (CapEx).
CapEx refers to money spent by a business to acquire, maintain, and upgrade physical assets such as property, buildings, or equipment.
2
Identify the financial model of the target cloud state.
The clinic will pay a variable monthly fee based on consumed resources, which represents an operating expenditure (OpEx).
OpEx represents the day-to-day expenses that a company incurs to keep its business running, such as utility bills or pay-as-you-go cloud services.
3
Determine the direction of the transition.
The transition moves from upfront capital costs to variable operating costs.

Show answer & explanation

Answer: Implement Amazon Simple Queue Service (Amazon SQS) to decouple the invoicing and reporting components, ensuring that a failure in report generation does not affect invoicing.; Use Amazon EC2 instances that are provisioned on demand to run the monthly reporting jobs and terminated immediately after the work is complete.

Answer

The company should implement Amazon Simple Queue Service (Amazon SQS) to decouple the invoicing and reporting components, and use Amazon EC2 instances that are provisioned on demand to run the monthly reporting jobs and terminated immediately after the work is complete.
Decoupling the invoicing and reporting components using Amazon Simple Queue Service (Amazon SQS) ensures that if the reporting service experiences issues, invoicing remains unaffected, fulfilling the loose coupling and design for failure principles. Additionally, provisioning Amazon EC2 instances on demand and terminating them once report generation is complete aligns with the principle of treating resources as disposable rather than static infrastructure.

Step-by-Step Solution

1
Analyze the requirements for loose coupling.
The invoicing process must not be interrupted by the reporting system, which requires decoupling them using a queueing service like Amazon SQS so that their lifecycles are independent.
This implements the 'loose coupling' and 'design for failure' principles.
2
Analyze the requirements for periodic resource utilization.
The reporting system only needs compute resources during the first week of the month, meaning compute resources should be created on demand and terminated when finished.
This implements the 'disposable resources' principle rather than keeping idle servers running constantly.
