How production scaling and improved Python architectural practices led to LNMP v3.0: deterministic 32s/28s sweeper concurrency, typed SQLAlchemy 2.0 repositories, Server-Sent Events, dual PostgreSQL/Redis storage, and multi-protocol synthetics.
How production multi-user deployments led to LNMP v2.0: implementing a 4-phase Sugiyama topology engine, TimescaleDB compression, top-of-minute write semaphores, and solving in-memory authentication deadlocks.
How we upgraded the Lightweight Network Monitoring Platform with TimescaleDB continuous aggregates, pure-Python FHRP inspection, Differential RCA, and an in-memory DAG topology engine.
Network visibility isn’t just a nice-to-have; it’s essential for keeping operations running smoothly
Introduction: Why Do We Need VPNs? The internet is fundamentally a wild, untrusted place
Most enterprise security guides assume you have an unlimited budget and a massive operations team
I have been spending quite a bit of my time labing on different data centre design models, and let's just say it has been a really exciting journey
Building a lab is one thing; making two different networking "philosophies" talk to each other is another game entirely
In an era where infrastructure is code, some aspects of networking still feel like a black box? Proprietary networking platforms, such as Cisco's IOS, Juniper's...
Imagine you've built a sleek, high-performance network, only for a single router or switch to fail and bring the entire thing down
In this part of our OSPF troubleshooting series, I redesigned the topology to include three areas: Area 0 (the backbone), Area 1, and Area 2
DOWNLOAD PACKET TRACER FILE To make this lesson easier to follow, I've included the Packet Tracer file for download
Having installed the pfSense firewall, it's crucial to establish firewall rules that safeguard your network's perimeter
From the last session , we successfully configured all the router interfaces and the switch with the IP addresses we generated while learning about subnetting
We're ready to start linking the switches to our networks, even though we have yet to configure the routes on the routers
Building on the previous post, I trust you've successfully set up the infrastructure by linking the routers in Cisco Packet Tracer following the provided steps ...
Building upon the foundational concepts of Network design covered in the previous lesson , where we delved into the intricacies of subnetting IPv4 addresses to...
PfSense stands out as an open-source firewall based on FreeBSD, earning its reputation as my top choice for live deployment in medium to small-scale enterprises...
In this blog series, I will guide you through the steps of creating a campus network using Cisco Packet Tracer
