Discuss Amazon CLF-C02 Exam Topic 4 Question 11

A company is running a monolithic on-premises application that does not scale and is difficult to maintain. The company has a plan to migrate the application to AWS and divide the application into microservices.

Which best practice of the AWS Well-Architected Framework is the company following with this plan?

AIntegrate functional testing as part of AWS deployment.

BUse automation to deploy changes.

CDeploy the application to multiple locations.

DImplement loosely coupled dependencies.

Suggested Answer: D

The company is following the best practice of implementing loosely coupled dependencies by migrating the application to AWS and dividing the application into microservices. Loosely coupled dependencies are a design principle of the AWS Well-Architected Framework that helps to reduce the interdependencies between components and improve the scalability, reliability, and performance of the system. By breaking down the monolithic application into smaller, independent, and modular services, the company can reduce the complexity and maintenance costs, increase the agility and flexibility, and enable faster and more frequent deployments. AWS CloudFormation is an AWS service that provides the ability to manage infrastructure as code. Infrastructure as code is a process of defining and provisioning AWS resources using code or templates, rather than manual actions or scripts. AWS CloudFormation allows users to create and update stacks of AWS resources based on predefined templates that describe the desired state and configuration of the resources. AWS CloudFormation automates and simplifies the deployment and management of AWS resources, and ensures consistency and repeatability across different environments and regions. AWS CloudFormation also supports rollback, change sets, drift detection, and nested stacks features that help users to monitor and control the changes to their infrastructure.Reference:Implementing Loosely Coupled Dependencies,What is AWS CloudFormation?

Not sure if this will solve their maintenance issues, though.

Theodora 11 months ago

Loosely coupled dependencies make sense for scaling.

Nikita 11 months ago

Wait, are they really going to split it up? Sounds complicated.

Whitley 12 months ago

I think they should focus on automation too!

Simona 12 months ago

They're definitely going for microservices with this move.

Charlene 12 months ago

I’m a bit confused. I thought deploying to multiple locations was more about redundancy, not really about migrating to microservices.

I feel like this question is similar to one we practiced on microservices and scaling. I think loosely coupled dependencies might be the right answer.

Rossana 1 year ago

I'm not entirely sure, but I remember something about automation in deployment. Could that relate to their migration plan?

Darnell 1 year ago

I think the company is focusing on breaking down the application, so maybe it's about implementing loosely coupled dependencies? That sounds familiar.

Izetta 1 year ago

I'm a little confused here. The question mentions scaling and maintenance, but none of the answer choices seem to directly address those issues. I'll have to re-read the question and options more closely to figure out the right approach.

Okay, I've got this. The company is moving away from a monolithic on-premises application, which is difficult to scale and maintain. Migrating to a microservices architecture on AWS is a clear example of the "Implement loosely coupled dependencies" best practice. That's my answer.

Hmm, I'm a bit unsure about this one. Dividing the application into microservices could relate to a few different best practices, like loose coupling or automation. I'll need to think this through carefully.

This seems like a straightforward question about the AWS Well-Architected Framework. I think the key is to identify which best practice the company is following by migrating to a microservices architecture.

Linn 1 year ago

This looks like a tricky networking question. I'll need to carefully read through the details and think through the different options.

I think market price is about demand and supply...pretty sure that was one of the key definitions we went over.

I remember a practice question that mentioned how autonomous services might increase composition size, but I'm not confident about that.

Hmm, I'm a little unsure about this one. I know Bloom's taxonomy covers different levels of learning, but I'm not totally confident in how to apply it to this specific scenario.

That's a good point. Automating the deployment process would definitely be important for a microservices-based application. Though I'm curious, do we know if they're actually doing that, or just planning to?

Aliza 3 years ago

Hmm, I was thinking more along the lines of 'Use automation to deploy changes'. Isn't that a key benefit of microservices, the ability to update individual components without affecting the whole system?

Letha 3 years ago

Yeah, I agree. Microservices are all about breaking down the application into smaller, independent components. That aligns with the 'Implement loosely coupled dependencies' principle from the AWS Well-Architected Framework.

Exactly! Implementing loosely coupled dependencies is key in microservices architecture.

Okay, let's think this through. Dividing the monolithic application into microservices seems like a good move to improve scalability and maintainability. I'd say the best practice they're following is 'Implement loosely coupled dependencies' - that's what microservices are all about, right?
