Creating Your Own CDN: A Step-by-Step Guide

Posted on by Owen

CDN, or Content Delivery Network, has become essential for improving website performance, reducing latency, and delivering content faster to users across the globe. While there are popular providers that are widely used, some tech-savvy website owners may prefer to create their own Content Delivery Network and have full control over their network. In this step-by-step guide, we’ll explain how to create your own CDN using GeoDNS, perfect for beginners looking to optimize content delivery worldwide.

What is a CDN?

A CDN is a network of distributed servers located across various geographic regions. These servers store copies of your website’s static content, such as images, stylesheets, and scripts. When a user visits your website, the CDN serves the content from the nearest server, reducing load times and improving the user experience.

Defending Against R.U.D.Y. Attack: What You Need to Know

Posted on by Owen

In today’s cybersecurity landscape, Distributed Denial of Service (DDoS) attacks continue to pose significant risks to organizations and businesses. One particularly stealthy and difficult-to-detect attack type is the R.U.D.Y. (R-U-Dead-Yet) attack. Unlike traditional DDoS attacks that overwhelm servers with traffic, R.U.D.Y. attacks focus on slowly consuming server resources, making them a unique and dangerous threat.

In this blog post, we will explore how R.U.D.Y. attacks work, their impact, and how you can defend your infrastructure from this type of cyberattack.

What is a R.U.D.Y. Attack?

R.U.D.Y. is a low-and-slow type of attack that targets web applications by exploiting HTTP POST requests. Instead of sending a large volume of traffic to a server like traditional DDoS attacks, R.U.D.Y. takes advantage of the way web servers handle HTTP POST requests by sending data in small, incomplete packets over a long period.

Heartbeat Monitoring: A Simple Way to Ensure Uptime

Posted on by Owen

In today’s always-on digital landscape, uptime is paramount. Critical applications, services, and systems must run continuously, and even minor disruptions can have significant consequences. A key technique that helps ensure uptime is heartbeat monitoring. This process continuously monitors the status and health of systems by relying on periodic “heartbeat” signals sent from a monitored service to a monitoring system.

One important application of this monitoring type is ensuring the successful execution of scheduled tasks such as cron jobs. This blog will explore how heartbeat monitoring works, its importance, and technical best practices, with a focus on how it can be applied to monitor all types of services, including scheduled jobs like cron tasks.

Keeping Your Website Up: HTTP/HTTPS Monitoring Basics

Posted on by Owen

HTTP/HTTPS Monitoring is a service that plays a vital role in maintaining your website’s uptime and reliability. By continuously checking the status of your website, this monitoring service helps you quickly identify and resolve issues before they impact your visitors or your business.

What is HTTP/HTTPS Monitoring?

HTTP/HTTPS Monitoring involves the regular checking of your website’s HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) status to ensure that your site is up and running smoothly. This service simulates a user’s attempt to access your site, verifying that your web server responds correctly and within an acceptable time frame. If the monitoring service detects any issues, such as a slow response or a failure to load, it immediately alerts you, allowing for quick remediation.

7 fundamental DNS record types

Posted on by Owen

The Domain Name System (DNS) is the backbone of the internet, a critical infrastructure that translates human-friendly domain names into the IP addresses that computers use to communicate. This intricate system relies on various types of records to direct online traffic, manage email delivery, and ensure domain authenticity. For anyone involved in web administration, understanding these DNS record types is not just beneficial—it’s essential. This expanded blog post delves deeper into the seven fundamental DNS record types, providing a thorough explanation of each and highlighting their pivotal roles in the digital ecosystem.

Introduction to DNS and Its Operational Essence

Before diving into the specific record types, it’s crucial to grasp what DNS is and how it operates. The DNS is often described as the internet’s phonebook. Just as a phonebook translates names into phone numbers, the DNS translates domain names (like www.example.com) into IP addresses (like 192.0.2.1 for IPv4 or 2001:0db8:85a3:0000:0000:8a2e:0370:7334 for IPv6). This system ensures users can access websites using easily memorable names rather than complex numerical addresses.

DNS resolution: Step-by-step guide

Posted on by Owen

DNS (Domain Name System) resolution is a crucial behind-the-scenes process that enables us to access websites, send emails, and connect to various services on the internet. While it might seem like magic, it’s a well-defined process that involves multiple steps. In this step-by-step guide, we’ll demystify DNS resolution and explain how it works.

Step 1: User Input

Everything starts with a user’s request to access a website or service. This request typically comes in the form of a URL (Uniform Resource Locator) entered into a web browser’s address bar or a similar input method. For example, when you type “www.example.com” into your browser, you’re initiating a DNS resolution process.

Anycast DNS: A Complete Guide

Posted on by Owen

In the intricate web of the internet, Domain Name System (DNS) plays a pivotal role, acting as a bridge between human-friendly domain names and IP addresses that computers use to locate each other on the vast network. Anycast DNS is a powerful technique that enhances the resilience, speed, and scalability of this fundamental system. In this comprehensive guide, we’ll dive deep into the world of Anycast DNS, exploring what it is, how it works, its advantages, and its impact on the internet.

Understanding DNS Basics

Before delving into Anycast DNS, let’s revisit the core concepts of DNS. The DNS is essentially a distributed system that translates human-readable domain names (like www.example.com) into machine-readable IP addresses (such as 192.0.2.1). When you type a URL into your web browser, a DNS resolver is responsible for finding the corresponding IP address so your browser can connect to the web server hosting the website.

GeoDNS: How to start using it?

Posted on by Owen

So you want to start using GeoDNS. Congrats! That means your business is growing or already big.

Step 0. Know what GeoDNS is?

A Geographical Domain Name System or GeoDNS is a method to distribute the traffic considering the location where the DNS query was generated. GeoDNS involves a network of name servers located in strategic points of the planet. These servers have different IP addresses for the same domain based on the region or area they cover, and that represents an incredible speed boost for the DNS resolution.

The trick of GeoDNS is that it redirects the traffic based on the DNS clients’ IP addresses.

Understanding the benefits of Round Robin DNS

Posted on by Owen

Are you looking for a way to improve your website or application’s performance, reliability, and security? Round Robin DNS is a great tool that can help you achieve these goals. In this article, we will take a closer look at the benefits of Round Robin DNS and how it can help you manage the traffic on your network.

What is Round Robin DNS?

Round Robin DNS is a DNS load-balancing technique that helps to balance the traffic load on a network by distributing the requests between multiple servers. It works by rotating the IP address of each server in the network so that the traffic is evenly distributed. This allows the network to handle more requests without running into performance issues. It can be used to increase the availability of websites, improve response times, and provide better scalability. It can also be used to improve the security of a website by preventing malicious traffic from one server from affecting the rest of the network. That is why, it can be a great tool for businesses that need to manage a large amount of traffic in a cost-effective way.
