Setting Up a Galera Cluster with GLB for Database Load Balancing
In high-demand environments where uptime and responsiveness are critical, databases often become the backbone of any application’s infrastructure. A Galera cluster offers a powerful solution for creating a high-availability database system with synchronous replication. When paired with GLB (Galera Load Balancer), you get efficient load distribution across the cluster, ensuring that no single database node…
Setting Up High Availability NFS Storage with DRBD and Pacemaker
In environments where uptime is critical, having a High Availability (HA) Network File System (NFS) storage solution can make a huge difference. A HA NFS setup ensures that services remain online and data remains accessible, even if one node fails. In this post, we’ll guide you through creating an HA NFS storage solution using DRBD…

Today, we take a look behind the scenes at the projects and vision of a versatile IT professional who harnesses technology to create impressive systems and solutions. From Vision to…
Optimizing Data Backup with A* Pathfinding: A Smarter Approach to VM Backup Management
In any data center environment, efficient data backup is essential. Managing backups for high volumes of data across virtual machines (VMs) comes with unique challenges, especially when multiple servers are involved. Our recent project took on these challenges by implementing a sophisticated A pathfinding algorithm* to determine the fastest, most efficient route for each backup.…
Enhancing Sports Journalism with NER Models for Tagging and Linking
In the fast-paced world of sports journalism, delivering detailed, relevant information quickly can set an article apart. To streamline this process, our sports editorial team has integrated a Named Entity Recognition (NER) model that not only identifies key tags in text but also, when necessary, inserts direct links to player or team profile pages. This…
Building a Robust Data API with MongoDB
Creating a scalable, flexible API to serve complex football data can be a challenge, especially when handling extensive datasets and frequent changes. Traditional relational databases like MySQL are reliable, but they may not be the best fit for dynamic data structures. In this project, we leverage MongoDB, a NoSQL database, to handle intricate football data—teams,…
How to Integrate HAProxy with Let’s Encrypt for SSL Certificate Management
Ensuring a secure HTTPS connection is a critical aspect of maintaining modern web services. Let’s Encrypt offers a fantastic way to automate the issuance of free SSL certificates. In this blog post, we’ll walk through a setup where HAProxy, a popular open-source load balancer, integrates with Let’s Encrypt to automate SSL certificate generation and renewal.…
Setting Up VRRP and Keepalived for Load Balancer Redundancy with HAProxy
To ensure high availability and redundancy in our load-balancing environment, we can leverage VRRP (Virtual Router Redundancy Protocol) with Keepalived. By configuring VRRP across two servers, we can assign virtual IPs (VIPs) that automatically migrate between servers in the event of a failure. This setup enables seamless failover, with each server acting as both a…
Understanding VRRP: Ensuring Network Resilience through Redundancy
The Virtual Router Redundancy Protocol (VRRP) is a network protocol designed to increase the availability of routing paths in a network. By creating a virtual router, VRRP allows multiple routers to work together, ensuring that if the primary router fails, a backup router can take over seamlessly. This failover capability is essential in networks where…
Understanding HAProxy: A Key Tool for Load Balancing and High Availability
HAProxy, short for High Availability Proxy, is a powerful and widely used open-source load balancer and reverse proxy solution. It plays a central role in ensuring that websites and applications can handle heavy traffic loads effectively and remain available, even when certain servers experience issues. What Does HAProxy Do? HAProxy is designed to distribute incoming…
Exploring the Pros and Cons of High Availability
High Availability (HA) is a key strategy in IT systems to ensure that applications and services remain accessible and operational, even during unexpected disruptions. Implementing HA can make a noticeable difference in the reliability and user experience of your systems, particularly when paired with tools like HAProxy, VRRP, and DNS. Let’s dive into the primary…
