The guide breaks down VLAN fundamentals with clarity covering switching, routing, load balancing, and effective network segmentation. Each concept is explained in a practical, real-world context making it easy to connect the theory to what you’ll encounter in actual environments
🌐 AWS Networking Fundamentals: Building Secure & Scalable Architectures 🔹 VPC (Virtual Private Cloud) 🔹 Subnets: Public vs Private 🔹 NAT Gateway 🔹 Load Balancer & API Gateway 🔹 Security Best Practices What's your go-to AWS networking pattern? 👇
AWS Networking — In 5 Seconds 🌐⚡ • VPC → your private cloud • Subnets → divide your network • Route Tables → control traffic flow • Security Groups → allow trusted access • NAT + IGW → internet in/out 📌 Understand this → everything else clicks.
What Exactly Is a VLAN? A VLAN (Virtual LAN) is a logical network created on a switch. Instead of using separate physical switches, a VLAN splits one switch into multiple isolated networks.
"With virtualbox, the magic sysrq key sequence cannot be sent to guest since it is always interpreted by the host. But the sysrq sequence can be sent using the management interface, e.g. VBoxManage controlvm [vbox-name] keyboardputscancode 1d 38 54 [press/release] d4 b8 9d

NETWORKING+ KNOWLEDGE CHECKPOINT A company has two VLANs on the same switch: •VLAN 10: 192.168.10.0/24 •VLAN 20: 192.168.20.0/24 Hosts in each VLAN can communicate within their own VLAN, but cannot communicate with the other VLAN, even though the switch shows both VLANs are…

A VLAN creates separate virtual networks on the same physical LAN. Here is what a tagged #Ethernet frame looks like with the VLAN header inserted 😎👇 Find high-res pdf books with all my #networking related infographics from study-notes.org
Configuración inicial en VirtualBox Abrimos VirtualBox y creamos una nueva máquina desde el menú Nueva Nueva Configuramos los parámetros de la máquina virtual, en primer lugar asignamos un nombre a la máquina virtual, definimos el tipo y versión del sistema operativo a usar y…
If you’re just starting with #VMs, don’t overthink it. Use #VirtualBox to learn the basics, jump to #VMware Workstation Player for smoother workflows, and try UTM if you’re on Apple Silicon. Start simple, break stuff, rebuild. That’s how you actually learn virtualization. #DevOps

Virtualization vs Containerization Virtualization creates multiple virtual machines (VMs) on a single physical server. Each VM runs its own complete operating system and uses a hypervisor to manage hardware resources. Containerization packages applications with their…

Le portail captif du CESI est une horreur. Je donne des formations là bas. VirtualBox en pont => en CLI t'as pas d'internet. VirtualBox en NAT => tu peux pas te connecter en SSH (sauf à faire une redirection de port) Tu peux faire 2 cartes réseau, mais c'est le bordel
