DDoS attacks have spread out lately, by exhausting the application and making it unavailable for use, and you can expect an attack of that type any time. Recently, Microsoft announced the support of Azure DDoS protection as a service for protecting Azure resources, such as Azure VMs, Load Balancers, and Application Gateways.

Azure DDoS protection comes in two flavors:

• Basic: This type has been around for a while as it is already enabled for Azure services to mitigate DDoS attacks. It incurs no charges.
• Standard: This flavor comes with more enhancements that mitigate attacks, especially for Azure VNet.
