What is Azure load balancer?

An Azure load balancer is a Layer-4 (TCP, UDP) load balancer that provides high availability by distributing incoming traffic among healthy VMs. A load balancer health probe monitors a given port on each VM and only distributes traffic to an operational VM.

What does 0.0 0.0 0 mean in a routing table?

all non local addresses0.0. 0.0/0 represents all possible IP addresses. In the context of the way routing tables get set up by default on AWS, 0.0. 0.0/0 is effectively “all non local addresses”.

What are azure availability zones?

Availability Zones are unique physical locations with independent power, network, and cooling. Each Availability Zone is comprised of one or more datacenters and houses infrastructure to support highly available, mission critical applications.

What is forced tunneling in Azure?

Forced tunneling lets you redirect or “force” all Internet-bound traffic back to your on-premises location via a Site-to-Site VPN tunnel for inspection and auditing. This is a critical security requirement for most enterprise IT policies.
