A media company is redesigning its video transcoding pipeline on AWS. Currently, a monolithic system receives uploaded videos, transcodes them, and stores the results. When multiple large files are uploaded at the same time, the system runs out of resources and fails, halting the entire pipeline. Which of the following architectural changes should the company implement to align with the AWS Cloud design principles of 'loose coupling' and 'services not servers'? (Select TWO.)

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Use Amazon Simple Queue Service (Amazon SQS) to buffer incoming transcoding requests, allowing the upload and transcoding components to operate independently.; Utilize AWS Lambda functions to execute the transcoding code automatically in response to upload events without provisioning or managing virtual servers.

Cevap

The correct architecture uses Amazon Simple Queue Service (Amazon SQS) to decouple the upload and transcoding components, and AWS Lambda to process transcoding tasks without managing underlying servers.
The correct selections are using Amazon Simple Queue Service (Amazon SQS) to buffer incoming transcoding requests and utilizing AWS Lambda to execute transcoding code. Amazon SQS decouples the upload and transcoding components so they do not depend on each other's immediate availability (implementing loose coupling). AWS Lambda runs code serverlessly in response to upload events, which removes the operational burden of managing, patching, and scaling physical or virtual servers (implementing services not servers).

Adım Adım Çözüm

1
Analyze the problem in the scenario: a monolithic transcoding system runs out of resources and fails when handling simultaneous uploads, causing the entire pipeline to fail.
Identified the need for decoupled, resilient components (loose coupling) and serverless computing to avoid managing virtual servers (services not servers).
This establishes which design principles are needed to solve the problem.
2
Evaluate the option regarding Amazon Simple Queue Service (Amazon SQS).
Amazon SQS acts as a message broker that decouples components, allowing them to scale independently and preventing failures in one component from taking down the other.
This implements the 'loose coupling' design principle.
3
Evaluate the option regarding AWS Lambda.
AWS Lambda is a serverless compute service that runs code in response to events (like file uploads) without requiring EC2 instance provisioning or management.
This implements the 'services not servers' design principle.
4
Verify that other options represent design anti-patterns (such as tight coupling, monolithic setups, or static provisioning).
The option suggesting a single EC2 instance and the option suggesting synchronous API calls represent tight coupling/monolithic designs, while the option suggesting pre-provisioning a static fleet ignores elasticity.
This confirms that the distractors are incorrect based on the design principles.

Cevap: Replatforming

Cevap

Replatforming is the correct migration strategy because the company is migrating its self-managed database to a fully managed database service (Amazon RDS) to reduce administrative overhead, without making changes to the core application code.
The correct answer is Replatforming. In a replatforming strategy, also known as 'lift-tinker-and-shift,' minor optimizations are made to the application during migration to take advantage of cloud capabilities (such as shifting from a self-managed database to a fully managed AWS service like Amazon RDS) without changing the core architecture or code of the application itself.

Adım Adım Çözüm

1
Analyze the migration scenario details and identify that the database is migrating from a self-managed setup on-premises to a fully managed AWS service (Amazon RDS).
This shows a platform optimization (shifting operational tasks to AWS) while leaving the core application code unchanged.
Identifying optimizations help differentiate between Rehosting and Replatforming.
2
Evaluate the architectural modifications to see if the core code or application layout is being restructured.
The core application code and server configuration remain unchanged, ruling out Refactoring.
Refactoring requires rewriting code to adapt to cloud-native paradigms.
3
Select the migration strategy that aligns with making optimizations without altering core code.
The strategy is classified as Replatforming (lift-tinker-and-shift).
Replatforming matches the scenario of substituting a self-managed database with a managed database service (RDS) without changing the core code.

An agricultural technology company runs a crop monitoring system. The system requires massive compute resources for two weeks during the bi-annual harvesting season to process telemetry data. For the remaining 11 months of the year, the compute demand is near zero. The company is evaluating the financial impact of migrating this workload from its on-premises data center to AWS. Which of the following represents the primary economic advantage of this migration?

Cevabı ve açıklamayı göster

Cevap: Leveraging elasticity to dynamically provision resources during the peak harvest weeks and terminate them afterward, shifting from a fixed capital expense (CapEx) to a variable operating expense (OpEx).

Cevap

Leveraging elasticity to dynamically provision resources during the peak harvest weeks and terminate them afterward, shifting from a fixed capital expense (CapEx) to a variable operating expense (OpEx).
The correct answer correctly identifies that the primary economic benefit comes from elasticity and the CapEx-to-OpEx shift. Since the telemetry processing workload is highly seasonal (active for only 4 weeks out of 52), paying for resources dynamically as an operating expense (OpEx) when they are actually running prevents the company from wasting money on idle physical infrastructure (CapEx) during the rest of the year.

Adım Adım Çözüm

1
Analyze the demand pattern of the workload.
The workload has a highly variable demand pattern, requiring massive compute capacity for only 4 weeks a year (two weeks twice a year) and minimal capacity otherwise.
Understanding the demand curve helps identify which cloud economic benefits (like elasticity) apply.
2
Evaluate the financial shift between on-premises and cloud models.
On-premises requires capital expenses (CapEx) to buy hardware for peak capacity. AWS allows paying for resources as variable operating expenses (OpEx) based on consumption.
This contrasts the fixed-cost model of physical hardware with the pay-as-you-go model of the cloud.
3
Determine the optimal cloud mechanism for cost reduction.
Elasticity allows the company to scale resources up during the peak harvest weeks and scale them back down when not in use, avoiding paying for idle capacity.
Elasticity directly matches resource supply with demand to optimize cloud spending.

Anahtar Kavram

The primary economic benefit of the cloud is the shift from capital expenses (CapEx) to variable operating expenses (OpEx), enabled by elasticity, allowing customers to pay only for the resources they consume.
