This post will explain what DDoS protection is offered in Azure and how to deploy Standard tier protection in a virtual network.
Distributed Denial of Service attacks have the potential to shut down a business. Often, we associate the term with hacktivists attacking high-profile companies or international espionage. However, businesses of all sizes are attacked this way. I’ve seen how a start-up tech business was attacked using a rented botnet and probably received a bribe request from the attacker to stop the flood of traffic.
DDoS protection systems are usually complex and specialized. Azure makes networking easy and this is true of DDoS protection. This was made generally available recently. Every virtual network has the Basic tier of DDoS protection enabled for free. Everyone gets it! Every resource connected to the virtual network is protected with added protection if you also have a Web Application Firewall offering external protection. There is also a Standard tier, which is paid for:

The Standard tier adds the following functionality:
The Basic tier of protection is enabled for you without any extra cost; it’s there automatically when you create a virtual network. The process of enabling Standard tier protection is pretty simple. It can be done when creating a virtual network or afterward. In the following example, I will show how to enable it afterward. The processes are almost identical.
Open the virtual network resource and click DDoS Protection under Settings. Here you can see the current tier of protection for the resources in the virtual network.
