Functionality: To monitors, filters, and blocks malicious requests to the website. it applies a set of
security rules to HTTP traffic to and from an application thereby protecting applications from common attacks, such as SQL injection, cross-site scripting (XSS), file inclusion, and improper system configuration.

Azure Traffic Manager
Role: DNS-based Traffic load balancer
Functionality: The Azure Traffic Manager performs periodic health checks to figure out when to automatically fail over traffic from the primary application server, when it is unhealthy, or unreachable, to the secondary application server.

Application Servers
Role: Host Servers
Functionality: An Application server is a server that hosts applications or software that delivers a business application through a communication protocol. Each Power Pages production websites consists of at least  two application server nodes hosted in different Azure Data center regions to provide high availability and disaster recovery. 

Microsoft Dataverse
Role: Cloud Data Storage Platform
Functionality: It acts as both Metadata store for the website storing all website configuration like webpages, content snippets, site settings, user metadata, and others and the data store for business data.
