What is an 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 do load balancers do?

Load balancers improve application availability and responsiveness and prevent server overload. Each load balancer sits between client devices and backend servers, receiving and then distributing incoming requests to any available server capable of fulfilling them.

What are the types of load balancer in Azure?

There are three load balancers in Azure: Azure Load Balancer, Internal Load Balancer (ILB), and Traffic Manager.

Does Azure need a load balancer?

IaaS applications require internal load balancing within a virtual network, using Azure Load Balancer. Application-layer processing refers to special routing within a virtual network. For example, path-based routing within the virtual network across VMs or virtual machine scale sets.

What is the difference between standard and basic Azure load balancer?

The Basic tier is quite restrictive. A load balancer is restricted to a single availability set, virtual machine scale set, or a single machine. The Standard tier can span any virtual machine in a single virtual network, including blends of scale sets, availability sets, and machines.

What is F5 Big-IP?

F5 BIG-IP is the overarching marketing name used to identify F5’s software suite of licensed “modules”. All of the modules sit “logically” inside of F5’s Traffic Management Operation System® (TMOS), in other words, they are all enabled via software.

What is F5 engineer?

What is Azure NAT Gateway?

NAT gateway provides outbound internet connectivity for one or more subnets of a virtual network. Once NAT gateway is associated to a subnet, NAT provides source network address translation (SNAT) for that subnet. NAT gateway specifies which static IP addresses virtual machines use when creating outbound flows.

What is Azure App Gateway?

Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. Traditional load balancers operate at the transport layer (OSI layer 4 – TCP and UDP) and route traffic based on source IP address and port, to a destination IP address and port.

What is big IQ?

BIG-IQ is a single, end-to-end solution for analyzing the health, performance, and availability of your F5 application delivery and security portfolio in any environment.

What is a big-IP?

The BIG-IP platform is a smart evolution of Application Delivery Controller (ADC) technology. Solutions built on this platform are load balancers. And they’re full proxies that give visibility into, and the power to control—inspect and encrypt or decrypt—all the traffic that passes through your network.

What is F5OS A?

Description. F5OS-A and F5OS-C software provide the underlying operating system for F5 appliance platforms and F5 chassis platforms that use a microservices platform layer. F5OS-A software is compatible with the F5 rSeries platform. F5OS-C software is compatible with the F5 VELOS chassis system.

What is SNAT port?

To establish an outbound connection, an ephemeral port is used to provide the destination with a port on which to communicate and maintain a distinct traffic flow. When these ephemeral ports are used for SNAT, they’re called SNAT ports. By definition, every IP address has 65,535 ports.

What is Azure private link?

Azure Private Link provides private connectivity from a virtual network to Azure platform as a service (PaaS), customer-owned, or Microsoft partner services. It simplifies the network architecture and secures the connection between endpoints in Azure by eliminating data exposure to the public internet.

How does a Web application firewall work?

A WAF protects your web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application, and prevents any unauthorized data from leaving the app. It does this by adhering to a set of policies that help determine what traffic is malicious and what traffic is safe.

What is Azure virtual network?

Azure Virtual Network (VNet) is the fundamental building block for your private network in Azure. VNet enables many types of Azure resources, such as Azure Virtual Machines (VM), to securely communicate with each other, the internet, and on-premises networks.
