Cevabı ve açıklamayı göster

Cevap: Refactoring (Re-architecting) for the multiplayer matchmaking system; Replatforming for the player profiles database

Cevap

Refactoring (Re-architecting) for the multiplayer matchmaking system, and Replatforming for the player profiles database.
Refactoring (Re-architecting) is correct for the matchmaking system because it involves rewriting the application code to implement a microservices-based, serverless architecture. Replatforming is correct for the player profiles database because the database is moved to a managed cloud database service (like Amazon RDS) to minimize administrative overhead while preserving the original database engine and schema.

Adım Adım Çözüm

1
Analyze the requirements for the multiplayer matchmaking system.
The workload requires a complete rewrite to migrate from a monolithic structure to a serverless, microservices-based architecture.
This workload requires modifying the code and design to leverage cloud-native features, which defines the Refactoring (Re-architecting) migration strategy.
2
Analyze the requirements for the player profiles database.
The database needs to move to a managed service to offload administrative tasks, but without changing the engine or schema.
This workload involves shifting to a managed service (such as Amazon RDS for PostgreSQL) while keeping the core schema and engine the same, which defines the Replatforming (lift-tinker-and-shift) strategy.

A media company is migrating its video processing pipeline to the AWS Cloud. The pipeline ingests raw video files, extracts metadata, transcodes the videos into multiple formats, and generates thumbnails. In the legacy on-premises system, all these tasks run sequentially on a single large server. If one task fails, the entire pipeline halts.

On AWS, the company wants to ensure that a failure in the thumbnail generation step does not interrupt video transcoding. Additionally, they want the compute capacity to automatically scale up during peak upload hours and scale down to zero when no videos are uploaded.

Which architectural approach on AWS directly addresses these requirements by applying the correct cloud design principles?

Cevap: Decouple the processing steps using Amazon Simple Queue Service (Amazon SQS) to achieve loose coupling, and use AWS Lambda functions to achieve elasticity.

Cevap

Decouple the processing steps using Amazon Simple Queue Service (Amazon SQS) to achieve loose coupling, and use AWS Lambda functions to achieve elasticity.
The correct choice proposes decoupling the steps using Amazon SQS queues and using AWS Lambda functions. This directly implements loose coupling, preventing a failure in one component from stopping the rest of the pipeline. It also implements elasticity by scaling compute resources automatically to match load and scaling down to zero when idle.

Adım Adım Çözüm

1
Analyze the system's resilience requirement.
Identify that isolating the thumbnail generation step so that it does not impact video transcoding requires a loosely coupled architecture.
Loose coupling ensures that components can fail independently without causing a cascade failure across the entire application pipeline.
2
Analyze the system's scaling and idle-state requirements.
Identify that dynamically scaling compute resources based on demand and scaling down to zero when idle requires elasticity.
Elasticity allows the application to automatically match resource supply with fluctuating demand, reducing costs during idle periods.
3
Evaluate the AWS services and principles described in the choices.
Select the option that decouples steps using Amazon SQS (loose coupling) and runs compute on AWS Lambda (elasticity and serverless scaling to zero).
Amazon SQS provides the queue buffering needed for loose coupling, and AWS Lambda provides event-driven serverless compute that scales to zero.

Anahtar Kavram

Loose coupling and elasticity are key design principles of the AWS Cloud that enable fault isolation and dynamic resource scaling.

Cevap: Deploying an Amazon Simple Queue Service (Amazon SQS) queue to buffer requests between the frontend web servers and the backend processing service; Utilizing Amazon Aurora Serverless instead of managing a relational database on self-provisioned Amazon EC2 instances

Cevap

The correct architectural decisions are using Amazon SQS to buffer and decouple requests, and utilizing Amazon Aurora Serverless to reduce operational overhead instead of self-managing a database on Amazon EC2.
The correct architectural decisions are using Amazon SQS to buffer requests and adopting Amazon Aurora Serverless. SQS allows components to interact asynchronously, ensuring that a bottleneck or failure in the backend does not impact the frontend's ability to receive requests, which is a classic example of loose coupling. Using a managed, serverless database service like Amazon Aurora Serverless represents the 'services, not servers' principle, shifting the operational burden of database management, patching, and scaling to AWS.

Adım Adım Çözüm

1
Analyze the scenario requirements
The startup needs a highly resilient architecture that requires minimal operational effort, which means applying principles such as loose coupling, services not servers, and design for failure.
This sets the criteria for evaluating the design choices.
2
Evaluate the option to use Amazon SQS
Amazon SQS provides an asynchronous communication channel that decouples the frontend from the backend, demonstrating loose coupling.
Loose coupling prevents a failure in one component from cascading to others, improving overall resilience.
3
Evaluate the option to use Amazon Aurora Serverless
Amazon Aurora Serverless is a fully managed service that eliminates the need to manage physical or virtual servers, demonstrating the services not servers principle.
Managed services minimize operational effort by offloading tasks like patching, backups, and scaling to AWS.
4
Evaluate the remaining options to identify anti-patterns
Monolithic architectures, single-instance configurations, and over-provisioned manual scaling are anti-patterns that violate loose coupling, design for failure, and elasticity.
This confirms that the other choices represent incorrect architectural practices.

Which of the following AWS Cloud benefits directly address these business and technical requirements? (Select TWO.)

Cevap: Stop spending money running and maintaining data centers; Stop guessing capacity

Cevap

The correct benefits are 'Stop spending money running and maintaining data centers' and 'Stop guessing capacity'.
The scenario requires solving two problems: unpredictability of initial player adoption, and the overhead of managing hardware/facilities. The benefit of 'Stop guessing capacity' resolves the first problem by allowing dynamic scaling to match actual user demand. The benefit of 'Stop spending money running and maintaining data centers' resolves the second problem by offloading racking, stacking, and hardware maintenance tasks to AWS, letting engineers focus on game development.

Adım Adım Çözüm

1
Analyze the technical requirements of the development team
The team cannot predict player adoption rates and wants to avoid under-provisioning or over-provisioning.
This requirement aligns with the AWS Cloud benefit of 'Stop guessing capacity', which allows dynamic scaling to match real-time load.
2
Analyze the business requirements of executive leadership
The leadership wants the engineering team to focus on game development rather than physical hardware infrastructure tasks.
This requirement aligns with the AWS Cloud benefit of 'Stop spending money running and maintaining data centers', which offloads infrastructure management to AWS.
3
Evaluate the remaining choices against AWS core benefits and principles
The remaining options either invert the CapEx/OpEx benefit, promote single zone monolithic structures, or suggest manual pre-provisioning of hardware.
These options are incorrect because they represent common misconceptions of cloud economics, elasticity, and design principles.
