Understanding Azure Content Delivery Network

Lab Details

  1. In this lab we will walk through the Azure Content Delivery Network where we will create Azure resources and Configure Content Delivery Network Endpoints.

  2. Duration: 90 minutes

Introduction

What is a Content Delivery Network?

  • (CDN) refers to a geographically distributed group of servers which work together to provide fast delivery of Internet content..

  • A CDN allows for the quick transfer of assets needed for loading Internet content including HTML pages, javascript files, stylesheets, images, and videos.

  • A properly configured CDN may also help protect websites against some common malicious attacks, such as Distributed Denial of Service Attack (DDoS).

What are Azure Network Security Groups (NSGs) ?

  • A network security group contains security rules that allow or deny inbound and outbound network traffic, to and from, several types of Azure resources. You can specify source and destination, port, and protocol for each rule.

  • A network security group contains zero, or as many rules as desired, within Azure subscription limits.

  • An Azure network security group is used to filter network traffic to and from Azure resources in an Azure virtual network. .

  • NSGs can be linked with subnets or individual virtual machine instances within that subnet. When an NSG is associated with a subnet, the ACL (access control list) rules apply to all Virtual Machine instances of that subnet. In addition, traffic to an individual virtual machine can be further restricted by associating an NSG directly to that virtual machine.
