[All CLF-C02 Questions]

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?

Show Suggested Answer Hide Answer
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?

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?

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?

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.

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?
