Page caching combined with Varnish can significantly boost the performance and scalability of web applications by serving cached pages directly from memory. In this article, we’ll explore how to utilize page caching in Rails along with Varnish as a reverse proxy cache to achieve optimal performance.
Page caching is a technique used to improve the performance of web applications by storing the entire HTML output of a page and serving it directly from the cache for subsequent requests. This eliminates the need to generate the page dynamically on each request, reducing server load and improving response times. In this article, we’ll explore the concept of page caching and discuss various solutions for implementing effective page caching strategies in web applications.
Redis is an open-source, in-memory data structure store known for its speed and flexibility. It serves as a high-performance database, cache, and message broker, offering various data structures such as strings, hashes, lists, sets, and sorted sets. In Rails applications, Redis is widely used for caching, session storage, background job processing, real-time analytics, and more. This article provides an introduction to Redis and its applications in Rails, along with a step-by-step installation guide for integrating Redis with a Rails application using the redis-rails gem.
A/B testing, also known as split testing, is a method used to compare two or more versions of a web page or application to determine which one performs better in achieving a predefined goal. This technique is widely used in web development, marketing, and user experience optimization to make data-driven decisions and improve overall performance. In this article, we’ll delve into the concept of A/B testing and explore how it can be implemented using the Split gem in Ruby on Rails.
In modern web application environments, load balancing plays a critical role in distributing traffic across multiple servers to ensure optimal performance, reliability, and scalability. Load balancing techniques and tools are deployed at various network layers, each with its own set of advantages and disadvantages. In this article, we’ll explore different types of load balancing at different network layers and provide examples.
In the realm of web servers, accurate logging of client IP addresses is crucial for security, analytics, and compliance purposes. However, when Nginx is deployed behind a reverse proxy, load balancer, or CDN, the IP addresses logged may not reflect the actual client IP addresses. This is where the Nginx Real IP module comes into play.
In today’s web development landscape, handling background job processing efficiently has become crucial for building robust and scalable applications. Sidekiq stands out as a popular choice among developers due to its simplicity, reliability, and powerful features.
Continuous Integration (CI) and Continuous Deployment (CD) are two essential practices in modern software development. These practices, often abbreviated as CI/CD, play a crucial role in ensuring the efficiency, reliability, and speed of the software development lifecycle.
CSRF (Cross-Site Request Forgery) is a type of attack where an attacker tricks a user into performing unintended actions on a web application in which the user is authenticated. In Rails, CSRF protection is implemented to prevent such attacks. This article explains what CSRF is, how it works in Rails, and the mechanisms used to prevent CSRF attacks.
In JavaScript, Promise and Deferred are essential concepts used to handle asynchronous operations, such as fetching data from a server or performing time-consuming tasks. They provide a more readable and manageable way to work with asynchronous code, making it easier to handle asynchronous tasks and their results.
