Getting Started with Public Load Balancers in Azure

Load balancers provide performance and high availability for applications and services.  In this video, we review Azure public load balancers including inbound connectivity from the internet.  We also review how to use the load balancer public IP address or IP prefix to support outbound internet access from the backend hosts.  Then we walk through steps to deploy a public load balancer in Azure.

Getting Started with Azure Internal Load Balancers

Load balancers provide performance and high availability for applications and services.  In this video, we review Azure internal load balancers including features of each SKU, or type of load balancer, load balancing algorithm and distribution modes and health probes.  Then we walk through steps to deploy an internal load balancer in Azure.

What you need to know about Azure Network Security Groups and Application Security Groups

This video covers what you need to know about Azure Network Security Groups and Application Security Groups.  I started with the idea of a quick video on Network Security groups.  Things snowballed from there, and it ended up being a comprehensive review of Network Security Groups (NSG) and application Security Groups (ASG).  I also added some bonus content on verifying IP flow with Network Watcher.  This video is intended as an introduction to NSG’s.  However, stick around even if you’ve used NSG’s for a while.  There may be some new information here for you.

Azure Networking, User Defined Routes, and Network Virtual Appliances

This video was intended to show User Defined Routes (UDRs) and a few items were added on to demonstrate how they work.  It starts with some Azure Networking Basics and then we review a hub and spoke network.  From there, A Windows Server with Routing and Remote Access Services (RRAS) is configured as a Network Virtual Appliance (NVA) to route traffic between the spokes in the network.  UDRs are configured on the spoke subnets that send inter-spoke traffic to the NVA.  After that, we add a firewall into the network and direct internet traffic to the firewall with a default route in the UDR.

Networking Basics, the OSI Model

This is the first of a series of videos on Computer Networking Basics.  In this video, we go over the OSI model and how it aligns with TCP/IP.  This is the basic fundamental to understanding a computer network.
