Q & A

What role does a message broker play in modern web applications?

A message broker, like RabbitMQ, helps manage communication between different services by facilitating asynchronous processing. This allows actions to be deferred and handled later, ensuring the application remains responsive.

How can scheduled tasks benefit an application?

Scheduled tasks automate repetitive actions, such as deleting inactive users or sending daily notifications. This reduces manual workload and ensures timely execution of critical operations.

Why is load balancing across data centers important?

Load balancing is crucial for maintaining service availability and reliability. By distributing traffic across multiple data centers, the system can prevent downtime and loss of revenue due to failures in any single location.

What is the difference between monolithic and microservices architecture?

Monolithic architecture is a single, unified codebase that can become complex and hard to manage as it grows. Microservices architecture, on the other hand, breaks the application into smaller, independent services that can be developed, deployed, and scaled individually.

What challenges arise with large monolithic applications?

Large monolithic applications can be difficult to maintain due to their complexity. Changes in one part of the system can affect others, making updates and scaling more challenging.

What are the benefits of using a mono repository for microservices?

Using a mono repository for microservices allows for centralized management of shared components and libraries, reducing duplication and ensuring consistency across different services.

Which frameworks are commonly used for frontend development?

Popular frontend frameworks include React, Vue, Angular, and Svelte. These frameworks provide tools and components to build dynamic and responsive user interfaces.

How do data management tools like Redux and Effector fit into modern applications?

Redux and Effector are state management libraries that help manage application state efficiently, ensuring that the UI remains in sync with the underlying data model.

What role do big data tools like Hadoop play in data processing?

Big data tools like Hadoop enable the processing of large datasets across distributed systems. They are essential for analyzing trends, generating reports, and handling data from various sources.

How does REST API facilitate communication between frontend and backend?

REST API allows frontend applications to communicate with backend services using standard HTTP methods. It provides a structured way to request and manipulate data, ensuring smooth interactions between the client and server.
